3. Loosen the level gauge bolt.
4. Drain ATF from drain plug and refill with new ATF. Always refillsame volume with drained ATF.
 To replace the ATF, pour in new ATF at the A/T fluid charging
pipe with the engine idling, at the same time drain the old ATF
from the radiator cooler hose return side.
 When the color of the ATF coming out is almost same as the color of the new ATF, the replacement is complete. The
amount of new ATF to use should be 30 to 50% increase of
the stipulated amount.
CAUTION:
 Use only Genuine NISSAN Matic J ATF. Do not mix with other ATF.
 Using ATF other than Genuine NISSAN Matic J AT F will cause deterioration in driveability and A/
T durability, and may damage the A/T, which is not covered by the warranty.
 When filling ATF, take care not to scatter heat generating parts such as exhaust.
 Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to MA-26, "
Checking A/T Fluid". If ATF is still dirty, repeat step
2. through 5.
7. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
8. Tighten the level gauge bolt.
Checking Transfer FluidINFOID:0000000001328921

Balancing Wheels (Bonding Weight Type)INFOID:0000000001328926
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.
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) ⇒ 40 g (1.41 oz) bal-
ance weight (closer to calculated balance weight value)
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)
Oil grade and Viscosity:
Refer to MA-9

a. Install balance weight in the position shown in the figure at right.
b. 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 unreusable; always replace with newones.
 Do not install more than three sheets of balance weight.
c. 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 5.0 g (0.18 oz) each or below.
 If either residual unbalance value exceeds 5.0 g (0.18 oz), repeat installation procedures.
Tire RotationINFOID:0000000001328927
 After rotation the tires, adjust the tire pressure.
 Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
 Do not include the T-type spare tire when rotating the tires.
 When installing wheels, tighte n them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
 Be careful not to tighten wh eel nut at torque exceeding the
criteria for preventing strain of disc rotor.
 Use NISSAN genuine wheel nu ts for aluminum wheels.

CAUTION:
 After any collision, inspect all seat belt assembli es, including retractors and other attached hard-
wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in use
during a collision, unless not damaged an d properly operating after minor collision.
Also inspect seat belt assemblies no t in use during a collision, and replace if damaged or improperly
operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal colli-
sion where the driver and passenger air bags are deployed.
 If any component of seat belt assembl y is questionable, do not repair.
Replace as seat belt assembly.
 If webbing is cut, frayed, or damaged, replace belt assembly.
 Never oil tongue and buckle.
 Use a genuine NISSAN seat belt assembly.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612911
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 w hether 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 inopera tive, 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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t 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.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000001612914
NOTE:
 This Procedure is applied only to models with In telligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
 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 NVIS /IVIS, an electrically controlled steering lock
mechanism 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 pow er 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 ″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 Steering SystemINFOID:0000000001327705
 In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle
condition, and then check wheel alignment.
 Observe the following precautions when disassembling.
