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

INFOID:0000000005524462

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:0000000005260305

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-III 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.

5. When the repair work is completed, return the ignition switch to the

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-III.

Precaution for Rear Suspension

INFOID:0000000005260306

• 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. There are no passengers in the vehicle.

• After installing suspension components, check the wheel alignment.

• Caulking nuts are not reusable. Always use new caulking nuts for installation. New caulking nuts are pre-

oiled, do not apply any additional lubrication.

ON-VEHICLE MAINTENANCE

REAR SUSPENSION ASSEMBLY

On-Vehicle Inspection

INFOID:0000000005260309

• Check all of the component mountings for any excessive looseness, or backlash. Repair or replace the com-

ponents as necessary.

• Check the components for any excessive wear, damage, or abnormal conditions. Repair or replace the com-

ponents as necessary.

• Check the shock absorbers for any oil leaks or damage, and replace as necessary.

Wheel Alignment Inspection

INFOID:0000000005260310

Rear Wheel Alignment Adjusting Bolts

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 lubricants are all full, and that the spare tire, jack, hand tools and mats

are in their designated positions, and there are no passengers in the vehicle.

2. Check the tires for incorrect air pressure and excessive wear. Refer to

WT-53, "Tire"

.

3. Check the wheels for runout and damage. Refer to

WT-47, "Inspection"

.

4. Check the wheel bearing axial end play.

5. Check the shock absorbers for any oil 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 rear suspension member for any damage.
8. Check the vehicle height. Refer to

FSU-25, "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

RSU-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.

2. 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

1. Measure camber of both the right and left wheels with a suitable

alignment gauge and adjust as necessary to specification.

2. If outside of the specified value, adjust the camber using the

adjusting bolt in the front lower link.

CAUTION:

After adjusting the camber then check the toe-in.

NOTE:

Camber changes about 0

°

5' with each graduation of the adjust-

ing bolt.

3. Tighten the adjusting bolt nuts to specification.

TOE-IN

• Measure the toe-in of the rear wheels. If toe-in is out of specification, inspect and replace any damaged or

worn rear suspension parts before adjusting.

• Adjust toe-in by turning adjusting bolt on rear lower link.

NOTE:

Toe changes about 1.5 mm (0.059 in) [One side] with each gradua-

tion of the adjusting bolt.

• Tighten the adjusting bolt nut to the specified torque.
