< PRECAUTION > [BASE AUDIO]PRECAUTIONS

PRECAUTIONPRECAUTIONSPrecaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000009266691

The Supplemental Restraint System such as AIR BAG and SEAT BELT PRE-TENSIONER, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRSsystem uses the seat belt switches to determine the front air bag deployment, and may only deploy one frontair bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.Information necessary to service the system safely is included in the SR and SB section of this Service Man-ual.WARNING: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed byan authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to personalinjury caused by unintentional activation of the system. For removal of Spiral Cable and Air BagModule, see the SR section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERSWARNING: When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with ahammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causingserious injury.

When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect thebattery, and wait at least 3 minutes before performing any service.

Precaution for Work INFOID:0000000009266692

When removing or disassembling each component, be careful not to damage or deform it. If a componentmay be subject to interference, be sure to protect it with a shop cloth.

When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the componentwith a shop cloth or vinyl tape to protect it.

Protect the removed parts with a shop cloth and prevent them from being dropped. Replace a deformed or damaged clip. If a part is specified as a non-reusable part, always replace it with a new one. Be sure to tighten bolts and nuts securely to the specified torque. After installation is complete, be sure to check that each part works properly. Follow the steps below to clean components:- Water soluble dirt: Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area. Then rub with a soft, dry cloth.- Oily dirt: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty

area. Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off. Then rub with a soft, dry cloth.- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.- For genuine leather seats, use a genuine leather seat cleaner.AV-6Revision: April 2013 2014 Versa Sedan

NORMAL OPERATING CONDITION< SYMPTOM DIAGNOSIS > [BASE AUDIO]

NORMAL OPERATING CONDITIONDescription INFOID:0000000009266708

The majority of the audio troubles are the result of outside causes (bad CD, electromagnetic interference,etc.).

NOISEThe following noise results from variations in field strength, such as fading noise and multi-path noise, orexternal noise from trains and other sources. It is not a malfunction. Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-

tains or buildings blocking the signal. Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the

antenna at a different time from the waves which reflect off mountains or buildings.The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-tion of each piece of electrical equipment to determine the cause.NOTE:The source of the noise can be found easily by listening to the noise while removing the fuses of electricalcomponents, one by one.Type of Noise and Possible Cause

Occurrence condition Possible cause

Occurs only when engine is ON.

A continuous growling noise occurs. The speed of the noise varies with changes in the engine speed. Ignition components

A whistling noise occurs while the engine speed is high. A booming noise occurs while the engine is running and the lighting switch is ON.

Generator

The occurrence of the noise is linked with the operation of the fuel pump. Fuel pump condenser

Noise only occurs when various electrical components are oper-ating.

A cracking or snapping sound occurs with the op-eration of various switches. Relay malfunction, audio unit malfunction

The noise occurs when various motors are operat-ing.

Motor case ground Motor

The noise occurs constantly, not just under certain conditions. Poor ground of antenna feeder line

A cracking or snapping sound occurs while the vehicle is being driven, especially when it is vibrating excessively.

PRECAUTIONS< PRECAUTION > [MID AUDIO]

PRECAUTIONPRECAUTIONSPrecaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000009266715

The Supplemental Restraint System such as AIR BAG and SEAT BELT PRE-TENSIONER, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRSsystem uses the seat belt switches to determine the front air bag deployment, and may only deploy one frontair bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.Information necessary to service the system safely is included in the SR and SB section of this Service Man-ual.WARNING: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed byan authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to personalinjury caused by unintentional activation of the system. For removal of Spiral Cable and Air BagModule, see the SR section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERSWARNING: When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with ahammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causingserious injury.

When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect thebattery, and wait at least 3 minutes before performing any service.
