PRECAUTIONS

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 “SRS AIRBAG” and “SEAT BELT” 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 “SRS AIRBAG”.
  
• 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.
  

When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc.

■ WARNING ■

Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

• Brake fluid use refer to 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.
• Never use mineral oils such as gasoline or light oil. They may damage rubber parts and cause improper operation.
• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with a crowfoot (A) and torque wrench (B).
  
  
• Always conform the specified tightening torque when installing the brake pipes.
• Brake system is an important safety part. If brake fluid leakage is detected, always disassemble the affected part. If a malfunction is detected, replace part with a new one.
• 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.

• When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor operating noise may be heard from engine compartment. This is normal.
• When an error is indicated by ABS or another warning lamp, collect all necessary information from customer (what symptoms are present under what conditions) and check for estimate causes before starting diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid level, and for oil leakage.
• If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts, stopping distance or steering stability may deteriorate.
• ABS might be out of order or malfunctioning by putting a radio (wiring inclusive), an antenna, or a lead-in wire near the control unit.
• If aftermarket parts (car stereo, CD player, etc.) are installed, check for incidents such as harness pinches, open circuits, and improper wiring.
• VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may illuminate.
• When replacing the following parts with parts other than genuine parts or making modifications: Suspension related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-related parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.), and body reinforcement-related parts (roll bar, tower bar, etc.).
• When driving with worn or deteriorated suspension, tires, or brake-related parts.
• Both “VDC” and “VDC-R” are used in this manual. These indicate the same system.

 

■ CAUTION ■

After finishing servicing, check that all the tools and waste are stored in a customary place.
