Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000007356989

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.

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

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT 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:0000000007356990

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

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

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. 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.

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

rotated.

4. Perform the necessary repair operation.

position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

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

Precaution for Front Suspension

INFOID:0000000007356991

• 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.

• 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:0000000007356996

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.

2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer to

WT-49, "Inspection"

4. Check the wheel bearing axial end play. Refer to

FAX-6, "On-Vehicle Inspection and Service"

5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the suspension member for any damage.
8. Check the vehicle height. Refer to

FSU-26, "Wheelarch Height (Unladen*1)"

GENERAL INFORMATION AND RECOMMENDATIONS

1. 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.

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

2. 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-25, "Wheel

Alignment (Unladen*1)"

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.

2. Most camera-type alignment machines are equipped with both "Rolling Compensation" method and

optional "Jacking Compensation" method to "compensate" the alignment targets or head units. "Rolling

Compensation" is the preferred method.

• If using the "Rolling Compensation" method, after installing the alignment targets or head units, push or

pull on the rear wheel to move the vehicle. Do not push or pull on the vehicle body.

• If using the “Jacking Compensation” method, after installing the alignment targets or head units, raise

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

NOTE:

Do not use the "Rolling Compensation" method if you are using sensor-type alignment equipment.

• Follow all instructions for the alignment machine you are using for more information.

CAMBER AND CASTER

1. 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.

2. 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

) with each graduation of one

adjusting bolt. Refer to table below for examples of lower link

adjusting bolt effect on camber and caster.
