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 “SRS AIR BAG” and “SEAT BELT” of this Service Manual WARNING: Always observe the following items for preventing accidental activation • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that 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 “SRS AIR BAG” • Never 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: Always observe the following items for preventing accidental activation • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never 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 Brake System INFOID:0000000008704277 WARNING: Since dust covering the front and rear brakes has an affect on human body, the dust must be removed with a dust collector Never splatter the dust with an air blow gun • Brake fluid use refer to MA-20, "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 For brake component parts, never wash them with water • Always confirm the specified tightening torque when installing the brake pipes • If the brake fluid or grease adheres to the disc rotor, quickly wipe it off • After pressing the brake pedal more deeply or harder than normal driving, such as air bleeding, check each item of brake pedal Adjust brake pedal if it is outside the standard value • 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 Revision: 2012 November BR-4 E26 PRECAUTIONS < PRECAUTION > • Tighten the brake tube flare nut to the specified torque with a flare nut torque wrench [(A), (commercial service tool)] • Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) harness connector (with ABS) or the battery negative terminal before performing the work • Check that no brake fluid leakage is present after replacing the parts • Brake component parts are critical safety parts If a brake fluid leak is detected, always disassemble the affected part If a malfunction is detected, replace part with a new one • Burnish the brake contact surfaces after refinishing or replacing rotors, after replacing brake pads, or if a soft pedal occurs at very low mileage - Front brake pad: Refer to BR-19, "BRAKE PAD : Inspection and Adjustment" - Front disc rotor: Refer to BR-19, "DISC ROTOR : Inspection and Adjustment" - Rear brake lining: Refer to BR-21, "BRAKE LINING : Inspection and Adjustment" - Rear brake drum: Refer to BR-21, "BRAKE DRUM :
