System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" B INFOID:0000000003120212 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C 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 “SRS AIRBAG” and “SEAT BELT” of this Service Manual D 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 E • 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 “SRS AIRBAG” BR • 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 G Precaution for Procedure without Cowl Top Cover INFOID:0000000003120216 When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc H I J PIIB3706J Precaution for Brake System K INFOID:0000000002913290 WARNING: Clean any dust from the front brake and rear brake with a vacuum dust collector Never blow with compressed air CAUTION: • Only use “DOT 3” brake fluid Refer to MA-11, "Fluids and Lubricants" • Never reuse drained brake fluid • Never spill or splash brake fluid on painted surfaces Brake fluid may seriously damage paint Wipe it off immediately and wash with water if it gets on a painted surface • Always clean with new brake fluid when cleaning the master cylinder, brake caliper and other components • Never use mineral oils such as gasoline or light oil to clean They may damage rubber parts and cause improper operation • Always loosen the brake tube flare nut with a flare nut wrench L M N O P Revision: 2007 October BR-5 T31 PRECAUTIONS [LHD] < PRECAUTION > • Tighten the brake tube flare nut to the specified torque with flare nut torque wrench (A) • Always confirm the specified tightening torque when installing the brake pipes • Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) connector or the battery negative terminal before performing the work • Check that no brake fluid leakage is present after replacing the parts • Burnish the brake contact surfaces after refinishing or replacing rotors, after replacing pads, or if a soft pedal occurs at JPFIA0061ZZ very low mileage - Front brake pad: refer
