The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.

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 inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

Precaution

INFOID:0000000001672900

• When installing the rubber bushings, the final tightening must be done under unladen condition and with the

tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immediately.

• Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The spare

tire, jack, hand tools, and mats are in their designated positions.

• After installing suspension components, check the wheel alignment.
• Lock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not

apply any additional lubrication.

Front Suspension Parts

INFOID:0000000001672926

Check front suspension parts for excessive play, cracks, wear and
other damage.
• Shake each front wheel to check for excessive play. If looseness is

noted:

- inspect wheel bearing end play. Refer to

FAX-5, "On-Vehicle

Inspection and Service"

- check ball joint end play. Refer to

FSU-9, "Inspection"

• Make sure that the cotter pin is inserted in drive shaft end (4WD

only).

• Retighten all nuts and bolts to the specified torque.

• Check shock absorber for oil leakage and other damage.
• Check suspension ball joint for grease leakage and ball joint dust

cover for cracks and other damage.

Front Wheel Alignment

INFOID:0000000001672927

PRELIMINARY INSPECTION

WARNING:

Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1.

Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.

Check the tires for incorrect air pressure and excessive wear.

Check the wheels for run out and damage. Refer to

WT-34, "Inspection"

Check the wheel bearing axial end play. Refer to

FAX-5, "On-Vehicle Inspection and Service"

Check the shock absorbers for leaks or damage.

Check each mounting point of the suspension components for any excessive looseness or damage.

Check each link, arm, and the suspension member for any damage.

Check the vehicle height. Refer to

FSU-24, "Wheelarch Height (Unladen*

GENERAL INFORMATION AND RECOMMENDATIONS

A Four-Wheel Thrust Alignment should be performed.
• This type of alignment is recommended for any NISSAN vehicle.
• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel

is centered.

• The alignment machine itself should be capable of accepting any NISSAN vehicle.

ON-VEHICLE SERVICE

• The alignment machine should be checked to ensure that it is level.

Make sure the alignment machine is properly calibrated.
• Your alignment machine should be regularly calibrated in order to give correct information.
• Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-

bration Schedule.

THE ALIGNMENT PROCESS

IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to

FSU-23, "Wheel

Alignment (Unladen*1)"

When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
• The alignment specifications programmed into your alignment machine that operate these indicators

may not be correct.

• This may result in an ERROR.

Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
• Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the

vehicle and rotate the wheels 1/2 turn both ways.

• See Instructions in the alignment machine you are using for more information.

CAMBER AND CASTER

Measure camber and caster of both the right and left wheels
with a suitable alignment gauge and adjust as necessary to
specification.

NOTE:
Some vehicles may be equipped with straight (non-adjustable)
lower link bolts and washers. In order to adjust camber and
caster on these vehicles, first replace the lower link bolts and
washers with adjustable (cam) bolts and washers.

If outside of the specified value, adjust camber and caster using
the adjusting bolts in the front lower link.

CAUTION:

After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 3' (0.05

) minutes with each graduation

of one adjusting bolt. Refer to table below for examples of lower
link adjusting bolt effect on camber and caster.

Tighten the adjusting bolt nuts to specification. Refer to

FSU-12, "Component"

TOE-IN

WARNING:

• Always perform the following procedure on a flat surface.
• Make sure that no person is in front of the vehicle before pushing it.

Bounce the front of vehicle up and down to stabilize the vehicle height (posture).

Push the vehicle straight ahead about 5 m (16 ft).

Put a mark on base line of the tread (rear side) of both front tires
at the same height as hub center as shown. These marks are
measuring points.

Measure the distance “A” on the rear side of the front tires as
shown.

Push the vehicle slowly ahead to rotate the wheels 180

degrees (1/2 a turn).

CAUTION:

If the wheels have rotated more than 180

degrees (1/2

turn), start this procedure again from the beginning. Never
push the vehicle backward.

Measure the distance “B” on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as “A” – “B”.

Adjust the toe-in by varying the length of the steering outer tie-
rods.

Loosen the outer tie-rod lock nuts.

Adjust the toe-in by screwing the outer tie-rods in or out.

Tighten the outer tie-rod lock nuts to specification.

FRONT WHEEL TURNING ANGLE

NOTE:
Check front wheel turning angle after the toe-in inspection.

Place front wheels on turning radius gauges in straight ahead
position and rear wheels on stands so that vehicle can be level.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.

Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.

• Any turning angles are not adjustable. If any of steering angles

are out of the specification, check if the following parts are
worn or damaged.

- Steering gear
- Steering column
- Front suspension components

If found that they are worn or damaged, replace them with new ones.
