VEHICLE DESIGNATIONSThe Vehicle Code Designations chart lists the vehi-

cle description and code for Cherokee and Wranglervehicles. The codes are used to identify vehicle typesin charts, captions and in service procedures. The ve-hicle codes are different than the Vehicle Identifica-tion Number (VIN) or the wheelbase/model code.

The following illustrations shows the labels, decalsand plates as well as locations on each vehicle.

VEHICLE SAFETY CERTIFICATION LABELA vehicle safety certification label (Fig. 1) is at-

tached to every Jeep vehicle. The label certifies thatthe vehicle conforms to all applicable Federal MotorVehicle Safety Standards. The label also lists: Gross vehicle weight rating (GVWR) and the grossfront and rear axle weight ratings (GAWRs) based ona minimum tire rim size and a maximum cold tireinflation pressure. Month and year of vehicle manufacture. Vehicle identification number (VIN). Type of vehicle. Month, day and hour (MDH) of final assembly.

The label is located on the driver-side door shut-face.

VEHICLE IDENTIFICATION NUMBER (VIN) PLATEThe Vehicle Identification Number (VIN) plate is

located on the lower windshield fence near the leftA-pillar. The VIN contains 17 characters that providedata concerning the vehicle. Refer to the VIN decod-ing chart to determine the identification of a vehicle.

The Vehicle Identification Number is also imprintedon the: Body Code Plate. Vehicle Safety Certification Label. Frame rail.

To protect the consumer from theft and possiblefraud the manufacturer is required to include aCheck Digit at the ninth position of the Vehicle Iden-tification Number. The check digit is used by themanufacturer and government agencies to verify theauthenticity of the vehicle and official documentation.The formula to use the check digit is not released tothe general public.

VEHICLE CODE PLATEA metal vehicle code plate is attached to the left

(driver) side of the dash panel in the engine compart-ment (Fig. 2). There can be a maximum of seven rowsof vehicle information imprinted on the plate. Theinformation should be read from left to right, startingwith line 1 at the bottom of the plate up through line7 (as applicable) at the top of the code plate.

Refer to the decoding chart to decode lines 1 upthrough 3.

Lines 4 through 7 (if used) on the vehicle code plateare imprinted on the plate (in sequence) according tothe following:

3-character sales code. 3-digit numerical code. 6-digit SEC code.

If there is not enough space left in the row for allof the 6-digit SEC code (if used): The unused space will remain blank. The code will be listed in the next row.

The last nine positions of row 7 will contain a2-digit code, when applicable, and a 6-digit gatelineserial number (same as the last 6 numbers of theVIN).

The last code imprinted on a vehicle code plate willbe followed by the imprinted word END. When twovehicle code plates are required, the last availablespaces on the first plate will be imprinted with theletters CTD (for continued).

When a second vehicle code plate is necessary, thefirst four spaces on each row will not be used becauseof the plate overlap.

ENGINE AND TRANSMISSION/TRANSFER CASEIDENTIFICATION

When required, refer to Group 9, Engines for allengine identification data. Refer to Group 21, Trans-missions for all transmission/transfer case identifica-tion data.

MAJOR COMPONENT IDENTIFICATIONWhen required, refer to the applicable service infor-

mation group for major component identificationdata.

VEHICLE DIMENSION DATAThe vehicle dimension data charts list the exterior

and interior dimensions for each type of Jeep vehicle.

VEHICLE LOAD DATAThe Vehicle Load Data chart lists the following in-

formation: Gross vehicle weight rating (GVWR). Gross axle weight ratings (GAWR). Cargo weight. Passenger weight for each Jeep type/body style.

TRAILER TOWING SPECIFICATIONSThe Trailer Towing Specification chart provide:

Minimum Vehicle requirements. The maximum trailer tongue weight. The maximum trailer weight. The maximum combined weight of the trailer/load/towing vehicle with a specific engine/transmission/axle combination.

INTERNATIONAL VEHICLE CONTROL AND DISPLAYSYMBOLS

Most of the graphic symbols illustrated in the fol-lowing chart are used to identify various instrumentcontrols and displays.

SPECIFICATION NOTATIONS

WARNING: THE USE OF INCORRECT ATTACHINGHARDWARE CAN RESULT IN COMPONENT DAM-AGE AND/OR PERSONAL INJURY.

It is important to retain the original attachinghardware for assembly of the components. If the at-taching hardware is not reusable, hardware withequivalent specifications must be used.

METRIC AND ENGLISH/SAE CONVERSIONThe following chart will assist in converting metric

units to equivalent English and SAE units, or viseversa.

TORQUE SPECIFICATIONS

TORQUE CHARTSA torque chart for fasteners is provided at the end

of each group (of service information). Refer to theTorque Specifications chart to determine torque val-ues not listed in the group.

It is important to be aware that the torque valueslisted in the chart are based on clean and dry boltthreads. Reduce the torque value by 10 percent whenthe bolt threads are lubricated and by 20 percent ifnew.

BOLT THREAD AND GRADE/CLASSIDENTIFICATION

THREAD IDENTIFICATIONSAE and metric bolt/nut threads are not the same.

The difference is described in the Thread Notationchart.

GRADE/CLASS IDENTIFICATIONThe SAE bolt strength grades range from grade 2 to

grade 8. The higher the grade number, the greaterthe bolt strength. Identification is determined by theline marks on the top of each bolt head. The actualbolt strength grade corresponds to the number of linemarks plus 2. The most commonly used metric boltstrength classes are 9.8 and 12.9. The metric strengthclass identification number is imprinted on the headof the bolt. The higher the class number,

the greater the bolt strength. Some metric nuts are

imprinted with a single-digit strength class on thenut face. Refer to the bolt identification and boltstrength chart.

METRIC CONVERSIONRefer to the chart to convert torque values listed in

metric Newton-meters (Nzm). Also, use the chart toconvert between millimeters (mm) and inches (in.)
