system safely is included in the SR and SB section of this Service Manual 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 by an authorized NISSAN/INFINITI dealer • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system For removal of Spiral Cable and Air Bag Module, see the SR section • Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury • When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery and wait at least minutes before performing any service Precaution for Work INFOID:0000000008945490 • When removing or disassembling each component, be careful not to damage or deform it If a component may 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 component with 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 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

[WITH VDC] < SYMPTOM DIAGNOSIS > NORMAL OPERATING CONDITION A Description INFOID:0000000008839749 B Symptom Result Brake pedal slightly vibrates and operation sound (motor sound and sound from suspension) occurs when VDC function, TCS function, ABS function, EBD function or hill start assist function operates Brake stopping distance may become longer than models without ABS function depending on the road conditions, when ABS function is operated on slippery road like rough road, gravel road or snowy road This is not a malfunction, because it is caused by VDC function, TCS function, ABS function, EBD function and hill start assist function that are normally operated C D Brake pedal vibrates and operation sound occurs during sudden acceleration and cornering, when VDC function or TCS function is operated Brake pedal vibrates and motor sound from the engine room occurs when the engine starts or the vehicle starts just after starting the engine Acceleration may be felt insufficient depending on the road conditions TCS function may operate momentarily while driving on a road where friction coefficient varies or when downshifting or fully depressing accelerator pedal ABS warning lamp and VDC warning lamp may turn ON when the vehicle is on a rotating turntable or is given a strong shaking or large vibrations on a ship while the engine is running VDC warning lamp may turn ON and VDC function and TCS function may not normally operate, when driving on a special road the is extremely slanted (bank in a circuit course) A malfunction in yaw rate/side/decel G sensor system may be detected when the vehicle sharply turns during a spin turn, acceleration turn or drift driving while VDC function and TCS function are OFF (VDC OFF switch is pressed and VDC OFF indicator lamp is in ON status) The vehicle speed does not increase when the accelerator pedal is depressed while the vehicle is on a 2-wheel chassis dynamometer for speedometer check This is not a malfunction because it is caused by operation check of ABS actuator and electric unit (control unit) This is not a malfunction because it is caused by TCS function that puts the highest priority to obtain the optimum traction (stability) E BRC G In this case, restart the engine on a normal road If the normal condition is restored, there is no malfunction In that case, erase “ABS” self-diagnosis result memory with CONSULT H This is normal (When checking the vehicle on a chassis dynamometer, operate VDC OFF switch so that TCS function is OFF.)
