Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a 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:
+ 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 in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+ Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the RS section.
+ 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 either just before
the harness connectors or for the complete harness are related to the SRS.
Precautions for Brake System
+Use brake ¯uid ``DOT 3''.
+ Never reuse drained brake ¯uid.
+ Be careful not to splash brake ¯uid on painted areas; it
may cause paint damage. If brake ¯uid is splashed on
painted areas, wash it away with water immediately.
+ To clean master cylinder parts, disc brake caliper parts or
wheel cylinder parts, use clean brake ¯uid.
+ Never use mineral oils such as gasoline or kerosene. They
will ruin rubber parts of hydraulic system.
+ Use ¯are nut wrench when removing and installing brake
tubes.
+ Always torque brake lines when installing.
WARNING:
Clean brakes with a vacuum dust collector to minimize risk of
health hazard from powder caused by friction.

Precautions
+When installing rubber parts, ®nal tightening must be car-
ried out under unladen condition* with tires on ground.
* Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+Use ¯are nut wrench when removing and installing brake
tubes.
+After installing removed suspension parts, check wheel
alignment and adjust if necessary.
+Always torque brake lines when installing.

Front Axle and Front Suspension Parts
Check front axle and front suspension parts for excessive play,
cracks, wear and other damage.
+Shake each front wheel to check for excessive play.
+Make sure that cotter pin is inserted.
+Retighten all axle and suspensions nuts and bolts to the speci-
®ed torque.
Tightening torque:
Refer to FRONT SUSPENSION (FA-24).
+Check front axle and front suspension parts for wear, cracks
and other damage.
+Check shock absorber for oil leakage and other damage.
+Check knuckle ¯ange for grease leakage and knuckle ¯ange
grease seal for cracks and other damage.
Front Wheel Bearing
+Check that wheel bearings operate smoothly.
+Check axial end play.
Axial end play:
0mm(0in)
+Adjust wheel bearing preload if there is any axial end play or
wheel bearing does not turn smoothly.

PRELOAD ADJUSTMENT
Adjust wheel bearing preload after wheel bearing has been
replaced or front axle has been reassembled.
Adjust wheel bearing preload as follows:
1. Before adjustment, thoroughly clean all parts to prevent dirt
entry.
2. Apply multi-purpose grease sparingly to the following parts:
+Wheel hub (as shown at left)
+Wheel bearing
+Grease seal lip
+Contact surface between wheel bearing lock washer (cham-
fered side) and outer wheel bearing
3. Tighten wheel bearing lock nut with Tool.
: 167 - 196 Nzm (17 - 20 kg-m, 123 - 145 ft-lb)
4. Turn wheel hub several times in both directions.
5. Loosen wheel bearing lock nut so that torque becomes0Nzm
(0 kg-m, 0 ft-lb).
6. Retighten wheel bearing lock nut with Tool.

TOE-IN
Measure toe-in using the following procedure.
WARNING:
+Always perform the following procedure on a ¯at surface.
+Make sure that no person is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. This mark is a measuring point.
4. Measure distance ``A'' (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180 degrees
(1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try
the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance ``B'' (front side).
Total toe-in:
Refer to SDS (FA-27).
7. Adjust toe-in by varying the length of steering tie-rod.
(1) Loosen lock nuts.
(2) Adjust toe-in by screwing tie-rod in and out.
Make sure both tie-rods are the same length.
(3) Tighten lock nuts to speci®ed torque.
Lock nut tightening torque:
Refer to ST section (``POWER STEERING GEAR
AND LINKAGE'').
FRONT WHEEL TURNING ANGLE
Turning angle is set by stroke length of steering gear rack and
cannot be adjusted.
1. Set wheels in straight-ahead position. Then move vehicle for-
ward until front wheels rest on turning radius gauge properly.
2. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Do not hold the steering wheel on full lock for more than 15
seconds.
Wheel turning angle (Full turn):
Refer to SDS (FA-27).
3. Adjust by stopper bolt if necessary.

Repacking Front Wheel Bearing and Axle Joint
Grease
FRONT WHEEL BEARING GREASE
Apply multi-purpose grease sparingly to the following parts:
+Threaded portion of spindle
+Contact surface between wheel bearing washer and outer
wheel bearing
+Grease seal lip
+Wheel hub (as shown at the left)
AXLE JOINT GREASE
+Drain approximately 2 liters (1-3/4 Imp qt) of differential oil.
+Remove knuckle spindle.
+Slightly pull out axle and repack axle joint with recommended
grease.
Refer to FA section.
Checking Free-running Hub Grease
Check free-running hub grease for leakage and water or dust entry.
Checking Water Entry in Knuckle Flange
+Check for water entry in knuckle ¯ange by removing one bolt
of lower knuckle ¯ange bearing cap and probing with a suitable
thin bar.
+After checking, be sure to reinstall the bolt to a tightening torque
of 30 to 40 Nzm (3.1 to 4.1 kg-m, 22 to 30 ft-lb).
Checking Brake Fluid Level and Leaks
If ¯uid level is extremely low, check brake system for leaks.
