Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           ELS000LQ


The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along                            B
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              C
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 and SB section of this Service Man-
ual.
WARNING:                                                                                                                 D
q    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 per-
     formed by an authorized NISSAN/INFINITI dealer.                                                                     E
q    Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
     sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
     Bag Module, see the SRS section.                                                                                    F
q    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 harness connec-
     tors.

 Engine drive belts                                                                                                MA-15 QR25DE or

 Exhaust system            Make sure there are no loose supports, cracks or holes. If the sound of the
                           exhaust seems unusual or there is a smell of exhaust fumes, immediately locate               MA-29
                           the trouble and correct it.
 Underbody                 The underbody is frequently exposed to corrosive substances such as those
                           used on icy roads or to control dust. It is very important to remove these sub-
                           stances, otherwise rust will form on the floor pan, frame, fuel lines and around
                                                                                                                          --
                           the exhaust system. At the end of winter, the underbody should be thoroughly
                           flushed with plain water, being careful to clean those areas where mud and dirt
                           can easily accumulate.
 Fluid leaks               Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
                           has been parked for a while. Water dripping from the air conditioner after use is
                                                                                                                          --
                           normal. If you should notice any leaks or gasoline fumes are evident, check for
                           the cause and correct it immediately.
