Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS composition which is available to NISSAN MODEL R20 is as follows (The composition
varies according to the destination and optional equipment.):
IFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
I For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
WARNING:
I 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 should be per-
formed by an authorized NISSAN dealer.
I Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
I Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for SRS ªAIR BAGº and ªSEAT
BELT PRE-TENSIONERº Service
IDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
I Before servicing the SRS, turn ignition switch ªOFFº, disconnect both battery cables and wait at least 3
minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
I Diagnosis sensor unit must always be installed with their arrow marks ª +º pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
I The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
I Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module (built-in type) standing with stud bolt side setting
bottom.
I Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
I After air bag inflates, the front instrument panel assembly should be replaced if damaged.
Precautions
IBefore proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to
prevent the internal parts from becoming contaminated by dirt or other foreign matter.
I Disassembly should be done in a clean work area.
I Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.
I Place disassembled parts in order for easier and proper assembly.
I All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
I Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
I It is very important to perform functional tests whenever they are indicated.
I The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place removed parts in a parts rack in order to replace them in correct positions and sequences. Care will
also prevent springs and small parts from becoming scattered or lost.
I Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.

Front Wheel Alignment
Before checking front wheel alignment, be sure to make a prelimi-
nary inspection.
PRELIMINARY INSPECTION
1. Check the tires for wear and proper inflation.
2. Check the wheel runout.Wheel runout:Refer to SDS, FA-39.
3. Check the front wheel bearings for looseness.
4. Check the front suspension for looseness.
5. Check the steering linkage for looseness.
6. Check that the front shock absorbers work properly by using the standard bounce test.
7. Measure vehicle height (Unladen): H = A þ B mm (in) Refer to SDS, FA-39.
(1) Exercise the front suspension by bouncing the front of the vehicle 4 or 5 times to ensure that vehicle is in a neutral height
attitude.
(2) Measure wheel alignment. Refer to SDS, FA-39.
(3) Measure vehicle posture ... Dimension ªHº. Refer to SDS, FA-39.
If ªHº dimension is not within the specified value, readjust
vehicle posture using anchor arm adjusting nut.
Refer to ªINSTALLATION AND ADJUSTMENTº, ªTorsion Bar
Springº, FA-31. Adjust wheel alignment if necessary.
(4) If wheel alignment is not as specified, but dimension ªHº is correct, adjust wheel alignment.
CAMBER, CASTER AND KINGPIN INCLINATION
Before checking camber, caster or kingpin inclination, move
vehicle up and down on turning radius gauge to minimize
friction. Ensure that vehicle is in correct posture (unladen
vehicle).
IMeasure camber, caster and kingpin inclination of both
right and left wheels with a suitable alignment gauge and
adjust in accordance with the following procedures.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replacable
halogen bulb. The bulb can be replaced from the engine compart-
ment side without removing the headlamp body.
IGrasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the bulb.
3. Pull off the rubber cap.
4. Press end of the retaining pin together to release bulb.
5. Remove the headlamp bulb. Do not shake or rotate the bulb when removing it.
6. Install the new bulb in reverse order of removal.
CAUTION:
I Do not leave headlamp reflector without bulb for a long
period of time as dust, moisture, smoke, etc. may enter the
headlamp body and affect the performance of the head-
lamp. Thus, the headlamp bulb should not be removed
from the headlamp reflector until just before a replacement
bulb is to be installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. For operating
instructions, of any aimer, it should be in good repair, calibrated and
used according to respective operation manuals supplied with the
unit.
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following:
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is noload in vehicle other than coolant,
engine oil filled up to correct level, full fuel tank and the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

Front Fog Lamp Aiming Adjustment
When performing fog lamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. The aimer should
be in good operational condition, calibrated and used according to
the relevant operation manuals supplied with the unit.
If an aimer is not available, aiming adjustment can be done as fol-
lows:
For details, refer to the regulations in your own country.
CAUTION:

I Place vehicle and tester on one and the same flat surface.
I Ensure that there is no-load in the vehicle other than
coolant, engine oil (filled up to correct level), full fuel tank
and the driver (or equivalent weight placed in driver's posi-
tion).
For details of front fog lamp aiming adjustment, refer to ªAiming
Adjustmentº, EL-47.
Check the distance between the vehicle and the ground illumina-
tion point of the main axis of the fog lamp beam. Keep the distance
to approximately 40 m (131 ft).
