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.
  

NOTE：

• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK position, then disconnect both battery cables.
  
• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both battery cables.
  
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
  

This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure below before starting the repair operation.

• Check the wheel hub and bearing assembly for looseness or smooth movement to the direction rotation.

Observe the following precautions when disassembling and assembling drive shaft.

• Never disassemble joint sub-assembly because it is non-overhaul parts.
• Perform work in a location which is as dust-free as possible.
• Clean the parts before disassembling and assembling.
• Prevent the entry of foreign objects must be taken into account during disassembly of the service location.
• Reassemble disassembled parts carefully in the correct order. If work is interrupted, a clean cover must be placed over parts.
