PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions f or Supplemental Restraint Syst em (S RS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

ELS001BF

The Sup plemental Restraint Syste m such as “AIR BAG” and “SEAT BELT PRE-TENSIONER ”, used along with a fron t seat be lt, hel ps to re duce th e risk or s everity of injur y to th e dr iver and fro nt pass enge r for cer tain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt sw itches to d etermine the fron t air bag dep loyment, and may on ly d eploy one fr ont 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 sectio n of this Service Manual.

WARNING:

● To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death

in the eve nt of a collision whic h would result in air bag inflation, all mai ntenance must be performed by an authorized NISSAN/INFINITI dealer.

● Improper mai ntenance, includin g incorrect removal an d installation of the SRS , can lead to per-

sonal injury caus ed by unin te ntional activati on of th e system . For rem oval of Spiral Cab le an d Air Bag Module, see the SR S section.

● Do not use electrica l test equipm ent on any circ uit related to the S RS unless in structed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harn esses or harness connectors .

The maintenance items listed here should be performed from time to time, unless otherwise specified.

Lamps

If the vehicle pulls to either side while driving on a straight and level road, or if you detect uneven or abnormal tire wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at normal highway speeds, wheel balancing may be needed.

Check for cracks or wear if they do not wipe properly.

Check that al l doo r s an d the engine ho od op erate smoot hly as we l l as t he back hatch. Also make sure that all latches lock securely. Lubricate if necessary. Make sure that the secondary latch keeps the hood from opening when the primary latch is released. When driving in areas using road salt or other corrosive materials, check lubrication frequently.

Make sure that the head lamps, stop lamps, tail lamps, turn signal lamps, and other lamps are all operating properly and installed securely. Also check head lamp aim. Clean the head lamps on a regular basis.
