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.

TOE-IN
1. Mark a base line across the tread.
After lowering front of vehicle, move it up and down to elimi-
nate friction, and set steering wheel in straight ahead position.
2. Measure toe-in.
Measure distance ªAº and ªBº at the same height as hub cen-
ter.Toe-in (Unladen):Refer to SDS, FA-39.
Toe-in = A þ B
3. Adjust toe-in by varying the length of steering tie-rods.
(1) Loosen clamp bolts or lock nuts.
(2) Adjust toe-in by turning the left and right tie-rod tubes an equal amount.
Make sure that the tie-rod bars are screwed into the tie-rod
tube more than 32.5 mm (1.280 in).
Make sure that the tie-rods are the same length. Standard length (A = B):287 mm (11.30 in)
(3) Tighten clamp bolts or lock nuts, to the specified torque.

Supplement Restraint System (SRS) ªAIR BAGº
and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System ªAir Bagº and ªSeat Belt Pre-tensionerº, used along with a seat belt, help
to reduce the risk or severity or injury to the driver and front passenger in a collision. The Supplemental
Restraint System consists of an air bag module (located in the center of the steering wheel and on the instru-
ment panel on the passenger side, where fitted), seat belt pre-tensioners, a diagnosis sensor unit, warning
lamp, wiring harness and spiral cable. Information necessary to service the system safely is included in the
BT sectionof this Service Manual.
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 must 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. SRS wiring harnesses (except ªSEAT BELT-TENSIONERº connector) can be iden-
tified with yellow harness connector and with yellow harness protector or yellow insulation tape
before the harness connectors.
Precautions
IUse only ªDOT 4º fluid from a sealed container.
I Never reuse drained brake fluid.
I Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
I To clean master cylinder parts, disc brake caliper parts or
wheel cylinder parts, use clean brake fluid.
I Never use mineral oils such as Petrol or kerosene. They
will ruin rubber parts of hydraulic system.
I Use flare nut wrench when removing and installing brake
tubes.
I Always torque brake lines when installing.
I Burnish the brake contact surfaces after refinishing or
replacing drums or rotors, after replacing pads or linings,
or if a soft pedal occurs at very low speed. Refer to ªBrake
Burnishing Procedureº, ªCheck and Adjustmentº, BR-5.
WARNING:
I Clean brakes with a vacuum dust collector to minimize risk
of health hazard from airborne materials.
I Avoid prolonged and repeated skin contact with brake
fluid.
I Wear protective clothing, including impervious gloves.
I Where there is a risk of eye contact, eye protection should
be worn Ð for example chemical goggles or face shield.
