Disconnect both battery cables The steering lock will remain released with both battery cables disconnected and the steering wheel can be turned Perform the necessary repair operation When the repair work is completed, re-connect both battery cables With the brake pedal released, turn the push-button ignition switch from ACC position to ON position, then to LOCK position (The steering wheel will lock when the push-button ignition switch is turned to LOCK position.) Perform self-diagnosis check of all control units using CONSULT Revision: July 2014 INL-3 2015 Model L33 O P PRECAUTIONS < PRECAUTION > Precaution for Work INFOID:0000000010510452 • 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

injury to the driver and front passenger for certain types of collision Information necessary to service the 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 three minutes
