Supplemental Restraint System (SRS) ``AIR
BAG'' (4WD models)
The Supplemental Restraint System ``AIR BAG'', used along with a seat belt, helps to reduce the risk or
severity of injury to the driver in a frontal collision. The Supplemental Restraint System consists of air bag
module (located in the center of the steering wheel), diagnosis sensor unit, warning lamp, wiring harness
and spiral cable. Information necessary to service the system safely is included in theRS sectionof this
Service Manual.
WARNING:
lTo 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 dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the
harness connectors or for the complete harness, for easy identification.

PRECAUTIONS AND PREPARATION
HA-1

Checking Refrigerant Leaks
PRELIMINARY CHECK
Perform a visual inspection of all refrigeration parts, fittings,
hoses, and components for signs of A/C lubricant leakage, dam-
age and corrosion.
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C leak
detector or equivalent. Ensure that the instrument is calibrated
and set properly per the operating instructions.
The leak detector is a delicate device. In order to use the leak
detector properly, read the operating instructions and perform
any specified maintenance.
Other gases in the work area or substances on the A/C
components, for example, anti-freeze, windshield washer
fluid, solvents and cleaners, may falsely trigger the leak
detector. Make sure the surfaces to be checked are clean.
Do not allow the sensor tip of the detector to come into
contact with any substance. This can also cause false read-
ings and may damage the detector.
1. Position probe approximately 5 mm (3/16 in) away from point
to be checked.
2. When testing, circle each fitting completely with probe.

PRECAUTIONS AND PREPARATION
MA-1

Depending on annual driving distance and engine types, different basic schedules are introduced here.
Please follow the appropriate schedule for the vehicle. Furthermore, according to the weather and atmo-
spheric conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more
frequent maintenance may be required, as shown in ``Maintenance Under Severe Driving Conditions''.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
