PRECAUTIONS

< PRECAUTION >

PRECAUTION

PRECAUTIONS

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

INFOID:0000000006246398

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:0000000006246399

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.

PRECAUTIONS

5. 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.)

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

Precaution for Road Wheel

INFOID:0000000008189303

• Genuine NISSAN aluminum wheel is designed for each type of vehicle. Use it on the specified vehicle only.

• Use Genuine NISSAN parts for the wheel nuts.

• Always adjusting the wheel balance prior to using them. For the balance weights, use Genuine NISSAN alu-

minum wheel weights.

• Use caution when handling the aluminum wheels, because they can be easily scratched. When removing

dirt, do not use any abrasives, a wire brush, or other items that may scratch the coating. Use a neutral deter-

gent if a detergent is needed.

• After driving on roads scattered with anti-icing salts, wash off the wheels completely.

• When installing road wheels onto the vehicle, always wipe off any dirt or foreign substances to prevent them

from being trapped between the contact surfaces of wheel.

• Never apply oil to nut and bolt threads.

Inspection

INFOID:0000000006246404

ALUMINUM WHEEL

1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If

deformed, remove wheel and check wheel runout.

CAUTION:

DO NOT use center hole cone-type clamping machines to

hold the wheel assembly during tire removal/installation or

balancing or damage to the wheel paint, cladding or chrome

may result. Use only rim-type or universal lug-type clamp-

ing machines to hold the wheel assembly during servicing.

a. Remove tire from wheel and mount wheel on a tire balance

machine.

b. Set dial indicator as shown. Refer to

WT-54, "Road Wheel"

3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.

STEEL WHEEL

1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks, and other damage. If deformed, remove wheel and check wheel

runout.

a. Remove tire from steel wheel and mount on a tire balance machine.
b. Set two dial indicators as shown.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around

the circumference of the wheel.

e. Calculate runout at each point as shown.

Select maximum positive runout value and the maximum nega-

tive value.

Add the two values to determine total runout. In case a positive

or negative value is not available, use the maximum value (neg-

ative or positive) for total runout. If the total runout value

exceeds the limit, replace the steel wheel.

Adjustment

INFOID:0000000006246406

BALANCING WHEELS (ADHESIVE WEIGHT TYPE)

Preparation Before Adjustment

Remove inner and outer balance weights from the road wheel using releasing agent, remove double-faced

adhesive tape from the road wheel.

CAUTION:

• Be careful not to scratch the road wheel during removal.

• After removing double-faced adhesive tape, wipe clean all traces of releasing agent from the road

wheel.

Wheel Balance Adjustment

• If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and

skip Step 2. below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2.

to calculate the correct size adhesive weight.

1. Set road wheel on balancer machine using the center hole as a guide. Start the balancer machine.
2. For balancer machines that only have a clip-on (rim flange) weight mode setting, follow this step to calcu-

late the correct size adhesive weight to use. When inner and outer imbalance values are shown on the

balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that

should be used. Select the outer balance weight with a value closest to the calculated value above and

install in to the designated outer position of, or at the designated angle in relation to the road wheel.

a. Indicated imbalance value

5/3 = balance weight to be installed

Calculation example:

23 g (0.81 oz)

5/3 (1.67) = 38.33 g (1.35 oz)

⇒

40 g (1.41 oz)

balance weight (closer to calculated balance weight value)

NOTE:

Note that balance weight value must be closer to the calculated

balance weight value.

Example:

37.4

⇒

35 g (1.23 oz)

37.5

⇒

40 g (1.41 oz)

3. Install balance weight in the position shown.

CAUTION:

• Do not install the inner balance weight before installing

the outer balance weight.

• Before installing the balance weight, be sure to clean the

mating surface of the road wheel.

• When installing balance weight (1) to road wheel, set it into the

grooved area (A) on the inner wall of the road wheel as shown

so that the balance weight center (B) is aligned with the bal-

ancer machine indication position (angle) (C).

CAUTION:

• Always use genuine NISSAN adhesive balance weights.

• Balance weights are non-reusable; always replace with

new ones.

• Do not install more than three sheets of balance weight.
