PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612926
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PrecautionINFOID:0000000001327568
 Before connecting or disco nnecting the BCM harness con-
nector, turn ignition switch “OFF” and disconnect the battery
cable from the negative terminal. Battery voltage is applied to
BCM even if ignition sw itch is turned “OFF”.
 When connecting or disconnect ing pin connectors into or
from BCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are not
any bends or breaks on BCM pin terminals.

Before replacing BCM, perform c ontrol unit input/output sig-
nal inspection and make sure whether BCM functions prop-
erly or not. Refer to WT-17, "
Control Unit Input/Output Signal
Standard".

2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheelrunout.
a. Remove tire from steel wheel and mount wheel on a tire balance machine.
b. Set two dial indicators as shown in the illustration.
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 below.
f. Select maximum positive runout value and the maximum nega- tive value. Add the two values to determine total runout.
CAUTION:
In case a positive or negative val ue is not available, use the
maximum value (negative or positive) for total runout.
g. If the total runout value exceeds the limit, replace steel wheel.

ROAD WHEEL TIRE ASSEMBLY
ROAD WHEEL TIRE ASSEMBLY
Balancing Wheels (Bonding Weight Type)INFOID:0000000001327574
REMOVAL
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
 Be careful not to scratch th e road wheel during removal.
 After removing double-faced adhesive tape, wi pe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT
 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 road wheels.
1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer unbalance value by 5/3 to determine balance weight t hat should be used. Select the outer balance weight
with a value closest to the calculated value above and inst all it to the designated outer position of, or at the
designated angle in relation to the road wheel.
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.
a. Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) ⇒ 37.5 g (1.32 oz) bal-
ance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
36.2 ⇒ 35 g (1.23 oz)
36.3 ⇒ 37.5 g (1.32 oz)
b. Install balance weight in the position shown in the figure.
c. When installing balance weight to road wheels, set it into the grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the tire
balance machine indication position (angle).
CAUTION:
 Always use genuine NISSAN adhesion balance weights.
 Balance weights are non-reusable; always replace with new ones.
 Do not install more than three sheets of balance weight.

d. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown in
the figure.
CAUTION:
Do not install one balance weig ht sheet on top of another.
3. Start tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the tire balance machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start tire balance machine. Make sure that inner and outer resid- ual unbalance values are 5 g (0.2 oz) each or below.
6. If either residual unbalance value exceeds 5 g (0.2 oz), repeat installation procedures.
Tire RotationINFOID:0000000001327575
1. Follow the maintenance schedule for tire rotation service intervals. Refer to MA-5, "Introduction of Peri-
odic Maintenance".
2. Do not include the spare tire when rotating the tires.
3. When installing the wheel, tighten wheel nuts to the specified torque.
CAUTION:
 When installing wheels, tighten th em diagonally by dividing the work two to three times in order
to prevent the wheels from developing any distortion.
 Be careful not to tighten wheel nut at torque exceeding the criteria for preventing strain of disc
rotor.
4. Perform the ID registration, after tire rotation. Refer to WT-19, "
ID Registration Procedure".
