Regenerative BrakingRegenerative braking enables theelectric drive motor to operate as agenerator when coasting or braking.Energy from the moving vehiclerecharges the hybrid battery.

The hydraulic disc brakes work withthe regenerative braking to insureeffective braking.

The braking system is computercontrolled and blends theregenerative braking with theconventional hydraulic disc brakesto meet any requirements fordeceleration. Because the controllerapplies the hydraulic brakes throughits high pressure accumulator, youmay occasionally hear the motordriven pump when it rechargesthe system. This is normal.

Driving and Operating 9-7

AutomaticTransmissionThe vehicle has an electronic shiftposition indicator within theinstrument panel cluster.

There are several different positionsfor the shift lever.

See “Range Selection Mode” in thissection.

P (Park): This position locks therear wheels. It is the best position touse when you start the enginebecause the vehicle cannot moveeasily.

When parked on a hill, especiallywhen the vehicle has a heavy load,you may notice an increase inthe effort to shift out of P (Park).See Shifting Into Park on page 9‑4.

{ WARNING

It is dangerous to get out of thevehicle if the shift lever is not fullyin P (Park) with the parking brakefirmly set. The vehicle can roll.

Do not leave the vehicle when theengine is running unless youhave to. If you have left theengine running, the vehicle canmove suddenly. You or otherscould be injured. To be sure thevehicle will not move, even whenyou are on fairly level ground,always set the parking brakeand move the shift lever toP (Park). See Shifting IntoPark on page 9‑4. If you arepulling a trailer, see “DrivingCharacteristics and Towing Tips”in the owner manual.

{ WARNING

If you have Four-Wheel Drive, thevehicle will be free to roll— evenif the shift lever is in P (Park)— ifthe transfer case is in Neutral. So,be sure the transfer case is in adrive gear, Two-Wheel Drive Highor Four-Wheel Drive High orFour-Wheel Drive Low— not inNeutral. See Shifting Into Parkon page 9‑4.

9-8 Driving and Operating

To rock the vehicle back and forthto get out of snow, ice, or sandwithout damaging the transmission,see “If the Vehicle is Stuck” in theowner manual.

N (Neutral): In this position,the engine and transmission arenot connected with the wheels.To restart the engine when thevehicle is already moving, useN (Neutral) only.

{ WARNING

Shifting into a drive gear while theengine is running at high speed isdangerous. Unless your foot isfirmly on the brake pedal, thevehicle could move very rapidly.You could lose control and hitpeople or objects. Do not shiftinto a drive gear while the engineis running at high speed.

Notice: Shifting out of P (Park) orN (Neutral) with the enginerunning at high speed maydamage the transmission. Therepairs would not be covered bythe vehicle warranty. Be sure theengine is not running at highspeed when shifting the vehicle.

D (Drive): This position is fornormal driving. It provides the bestfuel economy. If you need morepower for passing, and you are:. Going less than about 55 km/h

(35 mph), push the acceleratorpedal about halfway down.

. Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.

D (Drive) or M (Manual Mode) canbe used when towing a trailer,carrying a heavy load, driving onsteep hills, or for off-road driving.

You may want to shift thetransmission to a lower gearselection if the transmission shiftstoo often.

Downshifting the transmission inslippery road conditions could resultin skidding. See “Loss of Control” inthe owner manual.

When temperatures are very cold,the transmission's gear shifting maybe delayed, providing more stableshifts until the engine warms up.Shifts may be more noticeable witha cold transmission. This differencein shifting is normal.

M (Manual Mode): This positionlets drivers select the range of gearsappropriate for current drivingconditions. If the vehicle has thisfeature, see Manual Mode onpage 9‑9.

Automatic Transfer Case

The transfer case knob is located tothe left of the instrument panelcluster.

Use this dial to shift into and out offour-wheel drive.

You can choose among five drivingsettings:

Indicator lights in the switchesshow you which setting you are in.The indicator lights will come onbriefly when you turn on the ignitionand the last chosen setting will stayon. If the lights do not come on, you

should take the vehicle to yourdealer for service. An indicator lightwill flash while shifting. It will stay onwhen the shift is completed. If forsome reason the transfer casecannot make a requested shift, it willreturn to the last chosen setting.

2 m (Two-Wheel Drive High):This setting is used for driving inmost street and highway situations.The front axle is not engaged intwo-wheel drive. This setting alsoprovides the best fuel economy.

AUTO (Automatic Four-WheelDrive): This setting is ideal foruse when road surface tractionconditions are variable. Whendriving your vehicle in AUTO,the front axle is engaged, but thevehicle's power is primarily sent tothe rear wheels. When the vehicle'ssoftware determines a need formore traction, the system willtransfer more power to the frontwheels. Driving in this mode resultsin slightly lower fuel economy thanTwo-Wheel Drive High.

4 m (Four-Wheel Drive High):Use the four-wheel high positionwhen you need extra traction, suchas on snowy or icy roads or in mostoff-road situations. This setting alsoengages the front axle to help drivethe vehicle. This is the best settingto use when plowing snow.

4 n (Four-Wheel Drive Low) :This setting also engages the frontaxle and delivers extra torque.You may never need this setting.It sends maximum power to allfour wheels. You might chooseFour-Wheel Drive Low if you aredriving off-road in deep sand, deepmud, deep snow, and while climbingor descending steep hills.

The vehicle has StabiliTrak. Shiftinginto Four-Wheel-Drive Low will turnTraction Control and StabiliTrak off.See “StabiliTrak System” in theowner manual.

5. Start the engine and shift thetransmission to the desiredposition.

Excessively shifting the transfercase into or out of the differentmodes may cause the transfer caseto enter the shift protection mode.This will protect the transfer casefrom possible damage and willonly allow the transfer case torespond to one shift per 10 seconds.The transfer case may stay in thismode for up to three minutes.

Brakes

Regenerative BrakingRegenerative braking is a hybridtechnology that enables theelectric drive motor to operate as agenerator when coasting or braking.Energy from the moving vehiclerecharges the hybrid battery.

The hydraulic disc brakes work withthe regenerative braking to insureeffective braking, such as when ahigh braking demand is requested.

The braking system is computercontrolled and blends theregenerative braking with theconventional hydraulic disc brakesto meet any requirements fordeceleration. The controllerinterprets the braking request

and uses regenerative braking,conventional hydraulic braking or acombination of both as necessary.Because the controller applies thehydraulic brakes through its highpressure accumulator, you mayoccasionally hear the motor drivenpump when it recharges the system.This is normal.

In the event of a controller problem,the brake pedal may be harder topush and the stopping distancemay be longer.

Automatic TransmissionFluid

When to Check and ChangeAutomatic Transmission Fluid

It is usually not necessary tocheck the transmission fluid level.The only reason for fluid loss is atransmission leak or overheating thetransmission. If a small leak issuspected, then use the followingchecking procedures to check thefluid level. However, if there is alarge leak, then it may be necessaryto have the vehicle towed to adealer and have it repaired beforedriving the vehicle further.

Notice: Use of the incorrectautomatic transmission fluid maydamage the vehicle, and thedamages may not be covered bythe vehicle warranty. Always usethe automatic transmission fluidlisted in Recommended Fluidsand Lubricants on page 11‑2.

Change the fluid and filter at thescheduled maintenance intervals.See “Scheduled Maintenance”in the owner manual. Be sure touse the transmission fluid listed inRecommended Fluids andLubricants on page 11‑2.

How to Check AutomaticTransmission Fluid

Notice: Too much or toolittle fluid can damage thetransmission. Too much canmean that some of the fluid couldcome out and fall on hot engineparts or exhaust system parts,starting a fire. Too little fluidcould cause the transmissionto overheat. Be sure to get anaccurate reading if checking thetransmission fluid.

Before checking the fluid level,prepare the vehicle as follows:

1. Start the engine and park thevehicle on a level surface.Keep the engine running.

2. Apply the parking brake andplace the shift lever in P (Park).

3. With your foot on the brakepedal, move the shift leverthrough each gear range,pausing for about three secondsin each range. Then, move theshift lever back to P (Park).

4. Allow the engine to idle(500–800 RPM) for at leastone minute. Slowly release thebrake pedal.

5. Keep the engine running andpress the Trip/Fuel button ortrip odometer reset stem untilTRANS TEMP (TransmissionTemperature) displays on theDriver Information Center (DIC).

6. Using the TRANS TEMPreading, determine andperform the appropriate checkprocedure. If the TRANS TEMPreading is not within the requiredtemperature ranges, allow thevehicle to cool, or operate thevehicle until the appropriatetransmission fluid temperatureis reached.

Cold Check Procedure

Use this procedure only as areference to determine if thetransmission has enough fluid to beoperated safely until a hot checkprocedure can be made. The hotcheck procedure is the mostaccurate method to check the fluidlevel. Perform the hot checkprocedure at the first opportunity.

Use this cold check procedure tocheck fluid level when thetransmission temperature isbetween 24°C and 34°C(75°F and 93°F).

1. Locate the transmission dipstickat the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑4 for moreinformation.

2. Pull out the dipstick and wipe itwith a clean rag or paper towel.

3. Install the dipstick by pushingit back in all the way, waitthree seconds, and then pull itback out again.

4. Check both sides of the dipstickand read the lower level. Repeatthe check procedure to verify thereading.

5. If the fluid level is below theCOLD check band, add onlyenough fluid as necessary tobring the level into the COLDband. It does not take muchfluid, generally less than0.5 Liter (1 Pint). Do not overfill.

6. Perform a hot check at thefirst opportunity after thetransmission reaches anormal operating temperaturebetween 60°C and 75°C(140°F and 167°F).

7. If the fluid level is in theacceptable range, push thedipstick back in all the way.

Hot Check Procedure

Use this procedure to check thetransmission fluid level when thetransmission fluid temperatureis between 60°C and 75°C(140°F and 167°F).

The hot check is the mostaccurate method to check the fluidlevel. The hot check should beperformed at the first opportunityin order to verify the cold check.

The fluid level rises as fluidtemperature increases, so it isimportant to ensure the transmissiontemperature is within range.

1. Locate the transmission dipstickat the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑4 for moreinformation.

2. Pull out the dipstick and wipe itwith a clean rag or paper towel.

3. Install the dipstick by pushingit back in all the way, waitthree seconds, and then pull itback out again.

4. Check both sides of the dipstickand read the lower level. Repeatthe check procedure to verify thereading.

5. Safe operating level is within theHOT cross hatch band on thedipstick. If the fluid level is notwithin the HOT band, and thetransmission temperature isbetween 60°C and 75°C(140°F and 167°F), add ordrain fluid as necessary to bringthe level into the HOT band.

Tire PressureTires need the correct amount ofair pressure to operate effectively.

Notice: Neither tireunderinflation noroverinflation is good.Underinflated tires, or tiresthat do not have enough air,can result in:. Tire overloading andoverheating which couldlead to a blowout.

. Premature orirregular wear.

. Poor handling.

. Reduced fuel economy.

Overinflated tires, or tiresthat have too much air, canresult in:. Unusual wear.. Poor handling.. Rough ride.. Needless damage fromroad hazards.

The Tire and Loading Informationlabel on the vehicle indicates theoriginal equipment tires and thecorrect cold tire inflation pressures.The recommended pressure is theminimum air pressure needed tosupport the vehicle's maximum loadcarrying capacity.

For additional information regardinghow much weight the vehicle cancarry, and an example of the Tireand Loading Information label, see“Vehicle Load Limits” in the ownermanual. How the vehicle is loadedaffects vehicle handling and ridecomfort. Never load the vehicle withmore weight than it was designed tocarry.

When to Check

Check your tires once a monthor more.

How to Check

Use a good quality pocket-typegauge to check tire pressure.Proper tire inflation cannot bedetermined by looking at the tire.Check the tire inflation pressurewhen the tires are cold, meaning thevehicle has not been driven for atleast three hours or no more than1.6 km (1 mi).

Remove the valve cap from the tirevalve stem. Press the tire gaugefirmly onto the valve to get apressure measurement. If the coldtire inflation pressure matches therecommended pressure on theTire and Loading Information label,no further adjustment is necessary.If the inflation pressure is low, addair until the recommended pressureis reached. If the inflation pressureis high, press on the metal stemin the center of the tire valve torelease air.

Re-check the tire pressure with thetire gauge.

Return the valve caps on the valvestems to prevent leaks and keep outdirt and moisture.

10-20 Vehicle Care

Tire Pressure MonitorOperationThis vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly. The TPMS sensorsmonitor the air pressure in the tiresand transmit the tire pressurereadings to a receiver located inthe vehicle.

When a low tire pressure conditionis detected, the TPMS will illuminatethe low tire pressure warningsymbol located on the instrumentcluster. If the warning light comeson, stop as soon as possible and

inflate the tires to the recommendedpressure shown on the tire loadinginformation label. See “Vehicle LoadLimits” in the owner manual formore information.

A message to check the pressure ina specific tire displays in the DriverInformation Center (DIC). The lowtire pressure warning light and theDIC warning message come on ateach ignition cycle until the tiresare inflated to the correct inflationpressure. Using the DIC, tirepressure levels can be viewed.For additional information anddetails about the DIC operation anddisplays see Driver InformationCenter (DIC) on page 5‑11.

The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven.This could be an early indicator thatthe air pressure is getting low andneeds to be inflated to the properpressure.

A Tire and Loading Information labelshows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. See “Vehicle LoadLimits” for an example of the Tireand Loading Information label andits location. Also see Tire Pressureon page 10‑18.

The TPMS can warn about alow tire pressure condition but itdoes not replace normal tiremaintenance. See “Tire Inspection,”“Tire Rotation” and “Tires” in theowner manual for more information.

Notice: Tire sealant materials arenot all the same. A non-approvedtire sealant could damage theTPMS sensors. TPMS sensordamage caused by using anincorrect tire sealant is notcovered by the vehiclewarranty. Always use only theGM-approved tire sealantavailable through your dealeror included in the vehicle.

Factory-installed Tire Inflator Kitsuse a GM approved liquid tiresealant. Using non-approved tiresealants could damage the TPMSsensors. See Tire Sealant andCompressor Kit on page 10‑25 forinformation regarding the inflator kitmaterials and instructions.

TPMS Malfunction Light andMessage

The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. When thesystem detects a malfunction, thelow tire warning light flashes forabout one minute and then stays onfor the remainder of the ignitioncycle. A DIC warning messagealso displays. The malfunctionlight and DIC warning messagecome on at each ignition cycleuntil the problem is corrected.

Some of the conditions that cancause these to come on are:. The TPMS sensor matching

process was not done or notcompleted successfullyafter rotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process.See "TPMS Sensor MatchingProcess" later in this section.

. One or more TPMS sensorsare missing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed andthe sensor matching processis performed successfully.See your dealer for service.

. Replacement tires or wheelsdo not match the originalequipment tires or wheels.Tires and wheels other thanthose recommended couldprevent the TPMS fromfunctioning properly.See “Buying New Tires” inthe owner manual.

. Operating electronic devicesor being near facilities usingradio wave frequencies similarto the TPMS could cause theTPMS sensors to malfunction.

If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message comes onand stays on.

TPMS Sensor MatchingProcess

Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’s tires or replacing one ormore of the TPMS sensors.Also, the TPMS sensor matchingprocess should be performed afterreplacing a spare tire with a roadtire containing the TPMS sensor.The malfunction light and the DICmessage should go off at the nextignition cycle. The sensors arematched to the tire/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.See your dealer for service or topurchase a relearn tool.

There are two minutes to matchthe first tire/wheel position, andfive minutes overall to match allfour tire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.

The TPMS sensor matchingprocess is:

1. Set the parking brake.

2. Turn the ignition to ON/RUN withthe engine off.

3. Press Q and K on theRemote Keyless Entry (RKE)transmitter at the same time forapproximately five seconds.The horn sounds twice to signalthe receiver is in relearn modeand TIRE LEARNING ACTIVEmessage displays on the DICscreen.

4. Start with the driver sidefront tire.

5. Place the relearn tool againstthe tire sidewall, near the valvestem. Then press the button toactivate the TPMS sensor.A horn chirp confirms that thesensor identification code hasbeen matched to this tire andwheel position.

6. Proceed to the passenger sidefront tire, and repeat theprocedure in Step 5.

7. Proceed to the passenger siderear tire, and repeat theprocedure in Step 5.

8. Proceed to the driver side reartire, and repeat the procedurein Step 5. The horn soundstwo times to indicate the sensoridentification code has beenmatched to the driver side reartire, and the TPMS sensormatching process is no longeractive. The TIRE LEARNINGACTIVE message on the DICdisplay screen goes off.

9. Turn the ignition to LOCK/OFF.

10. Set all four tires to therecommended air pressurelevel as indicated on the Tireand Loading Information label.

Tire RotationTires should be rotated every12 000 km (7,500 mi).

Any time unusual wear isnoticed, rotate the tires as soonas possible and check thewheel alignment. Also check fordamaged tires or wheels. See“When It Is Time for New Tires”and “Wheel Replacement” in theowner manual for moreinformation.

The purpose of regular rotationis to achieve more uniformwear for all tires on the vehicle.The first rotation is the mostimportant. See “MaintenanceSchedule” in the owner manual.

Use this rotation pattern whenrotating the tires.

Adjust the front and rear tiresto the recommended inflationpressure on the Tire andLoading Information label afterthe tires have been rotated.See “Vehicle Load Limits” in theowner manual for an example ofthe label and its location on yourvehicle.

Reset the Tire Pressure MonitorSystem (TPMS). See TirePressure Monitor Operation onpage 10‑20.

Check that all wheel nuts areproperly tightened. See “WheelNut Torque” under “Capacitiesand Specifications” in the ownermanual.

Lightly coat the center of thewheel hub with wheel bearinggrease after a wheel change ortire rotation to prevent corrosionor rust build-up. Do not getgrease on the flat wheelmounting surface or on thewheel nuts or bolts.

Tire Chains

{ WARNING

Do not use tire chains. There isnot enough clearance. Tire chainsused on a vehicle without theproper amount of clearance cancause damage to the brakes,suspension, or other vehicleparts. The area damaged by thetire chains could cause loss ofcontrol and a crash. Use anothertype of traction device only if itsmanufacturer recommends it forthe vehicle's tire size combinationand road conditions. Follow thatmanufacturer's instructions.To avoid vehicle damage, driveslowly and readjust or remove thetraction device if it contacts thevehicle. Do not spin the wheels.If traction devices are used,install them on the rear tires.

If a Tire Goes FlatThis vehicle has a tire inflator kit.There is no spare tire, no tirechanging equipment, and no placeto store a tire.

It is unusual for a tire to blowoutwhile driving, especially if the tiresare maintained properly. If air goesout of a tire, it is much more likely toleak out slowly. But if there ever is ablowout, here are a few tips aboutwhat to expect and what to do:

If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your foot offthe accelerator pedal and grip thesteering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.

A rear blowout, particularly on acurve, acts much like a skid andmay require the same correction asused in a skid. Stop pressing theaccelerator pedal and steer tostraighten the vehicle. It may bevery bumpy and noisy. Gently braketo a stop, well off the road,if possible.

{ WARNING

Driving on a flat tire will causepermanent damage to the tire.Re-inflating a tire after it hasbeen driven on while severelyunderinflated or flat may cause ablowout and a serious crash.Never attempt to re-inflate a tirethat has been driven on whileseverely underinflated or flat.Have your dealer or an authorizedtire service center repair orreplace the flat tire as soon aspossible.

If a tire goes flat, avoid furthertire and wheel damage by drivingslowly to a level place and stopping,well off the road, if possible.Then do this:

1. Turn on the hazard warningflashers.

2. Park the vehicle. Set theparking brake firmly and putthe shift lever in P (Park).

3. Turn off the engine.

4. Inspect the flat tire.

If the tire has been separated fromthe wheel or has damaged sidewallsor large tears that allow rapid airloss, call a tire repair facility. See“Roadside Assistance Program” or“Roadside Service” in the ownermanual.

If the flat tire is due to a slow leakcaused by a nail or other similarroad hazard, the tire inflator kit maybe used to repair the damaged tire

temporarily. The kit uses a liquid tiresealant to seal small punctures inthe tread area of the tire.

After repairing a tire with the tireinflator kit, take the vehicle to anauthorized dealer to have the tireinspected and repaired as soon aspossible. The tire sealant is atemporary repair only. See TireSealant and Compressor Kit onpage 10‑25.

Jump Starting

{ WARNING

Personal injury, death, or damageto the vehicle can result if you tryjump starting or using a batterycharger on the high voltagehybrid battery. Use only the12-volt battery for jump startingand charging.

For more information about thevehicle battery, see Battery onpage 10‑13.

If the vehicle's 12‐volt battery hasrun down, you may want to useanother vehicle and some jumpercables to start your vehicle. Use thefollowing steps to do it safely.

{ WARNING

Batteries can hurt you. They canbe dangerous because:

. They contain acid that canburn you.

. They contain gas that canexplode or ignite.

. They contain enoughelectricity to burn you.

If you do not follow these stepsexactly, some or all of thesethings can hurt you.

Notice: Ignoring these stepscould result in costly damage tothe vehicle that would not becovered by the warranty.

Trying to start the vehicle bypushing or pulling it will notwork, and it could damage thevehicle.

1. Check the other vehicle. It musthave a 12‐volt battery with anegative ground system.

Notice: Only use a vehicle thathas a 12-volt system with anegative ground for jumpstarting. If the other vehicle doesnot have a 12-volt system with anegative ground, both vehiclescan be damaged.

2. Get the vehicles close enoughso the jumper cables can reach,but be sure the vehicles are nottouching each other. It couldcause a ground connection youdo not want. You would not beable to start your vehicle, andthe bad grounding could damagethe electrical systems.

To avoid the possibility of thevehicles rolling, set the parkingbrake firmly on both vehiclesinvolved in the jump startprocedure. Put the automatictransmission in P (Park) or amanual transmission inN (Neutral) before setting theparking brake. If you have afour-wheel-drive vehicle, be surethe transfer case is in a drivegear, not in N (Neutral).

Notice: If any accessories are lefton or plugged in during the jumpstarting procedure, they could bedamaged. The repairs would notbe covered by the vehiclewarranty. Whenever possible,turn off or unplug all accessorieson either vehicle when jumpstarting the vehicle.

3. Turn off the ignition on bothvehicles. Unplug unnecessaryaccessories plugged into thecigarette lighter or the accessorypower outlets. Turn off the radioand all the lamps that are notneeded.

This avoids sparks and helpssave both batteries. It couldsave the radio!

4. Open the hood on the othervehicle and locate thepositive (+) and negative (−)terminal locations on thatvehicle.

Your vehicle has a remotepositive (+) and a remotenegative (−) jump startingterminal. You should always usethese remote terminals insteadof the terminals on the battery.

6. Check that the jumper cablesdo not have loose or missinginsulation. If they do, you couldget a shock. The vehicles couldbe damaged too.

Before you connect the cables,here are some basic things youshould know. Positive (+) goesto positive (+) or to a remotepositive (+) terminal if the vehiclehas one. Negative (−) will go to aheavy, unpainted metal enginepart or a solid engine ground.

Do not connect positive (+) tonegative (−) or you will get ashort that would damage thebattery and maybe otherparts too. Do not connect thenegative (−) cable to thenegative (−) terminal on thedead battery because this cancause sparks.

7. Connect the red positive (+)cable to the positive (+) terminalof the vehicle with the deadbattery. Use a remotepositive (+) if the vehiclehas one.

8. Do not let the other end touchmetal. Connect it to thepositive (+) terminal of thegood battery. Use a remotepositive (+) if the vehiclehas one.

9. Now connect the blacknegative (−) cable to thenegative (−) terminal of thegood battery. Use a remotenegative (−) if the vehiclehas one.

Do not let the other end touchanything until the next step.The other end of the negative (−)cable does not go to the deadbattery. It goes to a heavy,unpainted metal engine part orto the remote negative (−)terminal on the vehicle withthe dead battery.

10. Connect the other end of thenegative (−) cable to theremote negative (−) terminal,on the vehicle with the deadbattery.

11. Now start the vehicle with thegood battery and run theengine for a while.

12. Try to start the vehicle thathad the dead battery. If it willnot start after a few tries,it probably needs service.
