PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT A

BELT PRE-TENSIONER"

EES0025U

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B

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 SRS and SB section of this Service Man-

ual.

WARNING:

G 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 per-

formed by an authorized NISSAN/INFINITI dealer.

G 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 SRS section.

G 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

harness connectors.
Precautions for work

G
EES0025V

G After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check

their operation.

G Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

WHEEL Inspection
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 wheel and mount wheel on a tire balance
machine. b. Set dial indicator as shown in the illustration. Refer to WT-38,
"Road Wheel" . 3. Check front wheel bearings for looseness. 4. Check front suspension for looseness.

REMOVAL

PFP:40300
A
EES001D6

1. Remove inner and outer balance weights from the wheel.

CAUTION:

Be careful not to scratch the wheel during removal.

2. Using releasing agent, remove double-faced adhesive tape from the wheel.

CAUTION:

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the wheel.

WHEEL BALANCE ADJUSTMENT

G If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting, select and adjust a drive-in weight mode suitable for wheels.

1. Set wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.

2. When inner and outer imbalance values are shown on the wheel balancer indicator, multiply outer imbalance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value and install it to the designated outer position of, or at the desig- F nated angle in relation to the road wheel.

CAUTION:

G Do not install the inner balance weight before installing the outer balance weight.

G Before installing the balance weight, be sure to clean the mating surface of the wheel.

Indicated imbalance value × 5/3 = balance weight to be installed

Calculation example:

23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance

weight (closer to calculated balance weight value)

Note that balance weight value must be closer to the calculated

balance weight value.

Example:

37.4 g = 35 g (1.23 oz)

37.5 g = 40 g (1.41 oz)

a. Install balance weight in the position shown.
b. When installing balance weight to wheels, set it into the grooved area on the inner wall of the wheel as shown so that the balance weight center is aligned with the wheel balancer indication position (angle).
CAUTION: G Always use Genuine NISSAN adhesion balance weights.
G Balance weights are not reusable; always replace with new ones.
G Do not install more than three sheets of balance weights.

c. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown.
CAUTION: Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the wheel balancer indication position (angle).
CAUTION: Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual imbalance values are 5 g (0.18 oz) each or below.
G If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.

Rotation

EES001PX

NOTE: Follow the maintenance schedule for tire rotation service intervals. Refer to MA-7, "PERIODIC MAINTENANCE" .
1. Rotate the tires on each side from front to back as shown. Do not include the spare tire when rotating the tires.

Wheel nut : 133 N·m (14 kg-m, 98 ft-lb)

CAUTION: When installing wheels, tighten them diagonally by dividing the work two to three times in order to prevent the wheels from developing any distortion.
2. Adjust the tire pressure to specification. Refer to WT-38, "Tire" .
3. After the tire rotation, retighten the wheel nuts after the vehicle has been driven for 1,000 km (600 miles), and also after every wheel and tire have been installed such as after repairing a flat tire.

DESCRIPTION

EES001DF

During driving, the low tire pressure warning system receives the signal transmitted from the transmitter installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) for this system has pressure judgement and trouble diagnosis functions.

FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the warning lamp in the combination meter comes on. To start the self-diagnostic results mode, ground the tire pressure warning check terminal. The malfunction location is indicated by the warning lamp flashing and the buzzer sounds.

REMOVAL AND INSTALLATION
REMOVAL AND INSTALLATION Transmitter (Pressure Sensor)
REMOVAL 1. Deflate tire. Unscrew transmitter nut and allow transmitter to fall into tire. 2. Gently bounce tire so that transmitter falls to bottom of tire.
Place wheel and tire assembly on tire changing machine and break both tire beads. Ensure that the transmitter remains at the bottom of the tire while breaking the bead.
3. Turn tire so that valve hole is at bottom, and gently bounce the tire to ensure transmitter is near valve hole. Carefully lift tire onto turntable and position valve hole (and transmitter) 270 degrees from mounting/dismounting head.
4. Lubricate tire well, and remove top side of tire. Reach inside the tire and remove the transmitter.
5. Remove the second side of the tire as normal.
INSTALLATION 1. Place first side of tire onto rim.
