PRECAUTIONS BR-3 < PRECAUTION > C D E G H I J K L M A B BR N O P PRECAUTION PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT INFOID:0000000006163262 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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air 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 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 har- ness 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 Igni- tion 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 3 minutes before performing any service. Precaution for Brake System INFOID:0000000006163263 • Always use recommended brake fluid. Refer to MA-21, "FOR NORTH AMERICA : Fluids and Lubricants" (United States and Canada), MA-22, "FOR MEXICO : Fluids and Lubricants" • Do not reuse drained brake fluid. • Be careful not to splash brake fluid on painted areas. • To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid. • Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system. • Use flare nut wrench when removing and installing brake tube. • Always check tightening torque when installing brake lines. • Before working, turn ignition switch to OFF and disconnect con- nectors for ABS actuator and electric unit (control unit) or battery terminals. • Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage. Refer to WARNING: • Clean brake pads and shoes with a waste cloth, then wipe with a dust collector. SBR686C |
