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. Information necessary to service the system safely is included in the “SRS AIR BAG” and
“SEAT BELT” of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000010297063

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-

THEFT SYSTEM).

• Remove and install all control units after disconnecting both battery cables with the ignition switch

in the LOCK position.

• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing

work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

Use the Intelligent Key or mechanical key to turn the ignition switch to the ACC position. At this time, the
steering lock will be released.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

Perform the necessary repair operation.

FSU-4

< PRECAUTION >

PRECAUTIONS

When the repair work is completed, return the ignition switch to the LOCK position before connecting the
battery cables. (At this time, the steering lock mechanism will engage.)

Perform a self-diagnosis check of all control units using CONSULT.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000010297064

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precautions for Suspension

INFOID:0000000010297065

CAUTION:

• When installing rubber bushings, the final tightening must be carried out under unladen conditions

with tires on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools

and mats are in designated positions.

• After servicing suspension parts, be sure to check wheel alignment.
• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are

pre-oiled, tighten as they are.

Check the mounting conditions (looseness, backlash) of each component and component conditions (wear,
damage) are normal.

BALL JOINT AXIAL END PLAY

Set front wheels in a straight-ahead position.

CAUTION:

Never depress brake pedal.

Place an iron bar or equivalent between transverse link and steering knuckle.

Measure axial end play by prying it up and down.

CAUTION:

• Be careful not to damage ball joint boot. Never damage the installation position by applying

excessive force.

INSPECTION

Description

CAUTION:

• Camber, caster, kingpin inclination angles cannot be adjusted.
• If camber, caster, or kingpin inclination angle exceeds the standard value, check front suspension

parts for wear and damage. Replace suspect parts if a malfunction is detected.

• Kingpin inclination angle is reference value, no inspection is required.
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

Preliminary Check

Check the following:
• Tires for improper air pressure and wear
• Road wheels for runout: Refer to

WT-57, "Inspection"

• Wheel bearing axial end play: Refer to

• Transverse link ball joint axial end play: Refer to

FSU-6, "Inspection"

• Strut operation.
• Each mounting part of axle and suspension for looseness and deformation
• Each of suspension member and transverse link for cracks, deformation and other damage
• Vehicle height (posture)

CAMBER, CASTER, AND KINGPIN INCLINATION ANGLES

• Camber, caster, kingpin inclination angles cannot be adjusted.
• Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand at the

same height so that vehicle remains horizontal.

Using a CCK Gauge

Install the CCK gauge attachment (SST: KV991040S1) with the following procedure on wheel, then measure
wheel alignment.
1.

Remove three wheel nuts, and install the guide bolts to hub bolt.

Screw the adapter into the plate until it contacts the plate tightly.

Screw the center plate into the plate.

Insert the plate assembly on the guide bolt. Put the spring in,
and then evenly screw the three guide bolt nuts. When fastening
the guide nuts, do not completely compress the spring.

Place the dent of alignment gauge onto the projection of the
center plate and tightly contact them to measure.

CAUTION:

• If camber, caster, or kingpin inclination angle exceeds the

standard value, check front suspension parts for wear and
damage. Replace suspect parts if a malfunction is
detected.

• Kingpin inclination angle is reference value, no inspection

is required.

Toe-In

Measure toe-in by the following procedure.

WARNING:

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

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

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

Put matching mark (A) on base line of the tread (rear side) of
both tires at the same height of hub center. These are measur-
ing points.

Measure distance (A) (rear side).

Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
NOTE:
If the wheels rotates more than 180 degrees (1/2 turn), start this
procedure again from the beginning. Do not push the vehicle
backward.

Measure distance (B) (front side).

• If toe-in exceeds the standard value, adjust toe-in by varying the length of between steering outer socket

and inner socket.
