Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000009014373 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of 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 minutes before performing any service Precaution for Work INFOID:0000000009014374 • 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 seats, use a genuine leather seat cleaner Revision: October 2012 PWC-6 2013 Pathfinder NAM PREPARATION [LH FRONT ONLY AUTO DOWN] < PREPARATION > PREPARATION A PREPARATION Special Service Tool INFOID:0000000008942199 B The actual

ON position or during the retained power operation after ignition switch turns OFF • Power window main switch can open/close door glass • Front and rear power window switch can open/close the corresponding door glass • Power window lock switch can lock all power windows other than driver seat • All power windows open when pressing Intelligent Key unlock button for seconds • Power window serial link transmits the signals from power window main switch to each power window switch POWER WINDOW AUTO-OPERATION • AUTO-DOWN operation can be performed when the front power window motor LH turns to AUTO • Encoder continues detecting the movement of power window motor and output the encoder pulse signal to power window switch while power window motor is operating • Power window motor is operable in case encoder is malfunctioning • AUTO-DOWN function does not operate if encoder is malfunctioning RETAINED POWER OPERATION • Retained power operation is an additional power supply function that enables power window system to operate during the 45 seconds even when ignition switch is turned OFF Retained Power Function Cancel Conditions • Front door CLOSE (door switch OFF)→OPEN (door
