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 an air
bag module (located in the center of the steering wheel), a diagnosis sensor unit, warning lamp, wiring har-
ness 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.

bag module (located in the center of the steering wheel), a diagnosis sensor unit, warning lamp and spiral

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.
Precautions for Steering System
lBefore disassembly, thoroughly clean the outside of the unit.
lDisassembly should be done in a clean work area. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
lFor easier and proper assembly, place disassembled parts in order on a parts rack.
lUse nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
lBefore inspection or reassembly, carefully clean all parts with a general purpose, non-flammable
solvent.
lBefore assembly, apply a coat of recommended ATF* to hydraulic parts. Petroleum jelly may be
applied to O-rings and seals. Do not use any grease.
lReplace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-
lation. Perform functional tests whenever designated.
*: Automatic Transmission Fluid type DEXRON
TMII E, DEXRONTMIII, or equivalent.
PRECAUTIONS AND PREPARATION
ST-1

Steering System
Checking and Adjusting Drive Belts (For
power steering)
Refer to MA section (``Checking Drive Belts'', ``ENGINE MAIN-
TENANCE'').
Checking Fluid Level (For power steering)
Check fluid level with engine off.
Check fluid level with dipstick on reservoir cap.
Use ``HOT'' range for fluid temperatures of 50 to 80ÉC (122 to
176ÉF). Use ``COLD'' range for fluid temperatures of 0 to 30ÉC
(32 to 86ÉF).
CAUTION:
lDo not overfill.
lRecommended fluid is Automatic Transmission Fluid
type ``DEXRONTMII E, DEXRONTMIII'', or equivalent.

Checking Neutral Position on Steering Wheel
lMake sure that wheel alignment is correct.
Wheel alignment:
Refer to FA section (``Inspection and Adjustment'',
``SERVICE DATA AND SPECIFICATIONS'').
lVerify that the steering gear is centered before removing the
steering wheel.
Checking
1. Check that the steering wheel is in the neutral position when
driving straight ahead.
2. If it is not in the neutral position, remove the steering wheel
and reinstall it correctly.
3. If the neutral position is still not correct:
a. Loosen tie-rod lock nuts.
b. Move tie-rods, in opposite direction, the same amount on
both left and right sides.
This will compensate for error in the neutral position.
Checking Front Wheel Turning Angle
1. Rotate steering wheel fully right, then left; measure turning
angle.
Turning angle of full turns:
Refer to FA section (``Inspection and Adjustment'',
``SERVICE DATA AND SPECIFICATIONS'').
2. If it is not within specification, check stopper bolt adjustment.
Refer to FA section (``FRONT WHEEL TURNING ANGLE'',
``Front Wheel Alignment'').
Checking Hydraulic System (For power
steering)
Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve. Then bleed air. Refer to
``Bleeding Hydraulic System'', ST-5.
2. Run engine at idle speed or 1,000 rpm.
lMake sure temperature of fluid in reservoir tank rises to
60 to 80ÉC (140 to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine
is started with shut-off valve closed, fluid pressure in power
steering pump increases to maximum. This will raise fluid
temperature abnormally.
3. Check pressure with steering wheel fully turned to left and
right positions while idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel at full lock position for more
than 15 seconds.
Oil pump maximum pressure:
7,649 - 8,238 kPa (76.5 - 82.4 bar, 78 - 84 kg/cm
2,
1,109 - 1,194 psi) at idling
