Changing A/T Fluid

NLS00041

1.

Warm up ATF.

2.

Stop engine.

3.

Loosen the level gauge bolt.

4.

Drain ATF from drain plug and refill with new ATF. Always refill
same volume with drained ATF.

●

To replace the ATF, pour in new ATF at the A/T fluid charging
pipe with the engine idling and at the same time drain the old
ATF from the radiator cooler hose return side.

●

When the color of the ATF coming out is about the 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 ATF 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-19, "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 Differential Gear Oil

NLS00042

Check for oil leakage.

CHASSIS AND BODY MAINTENANCE

Changing Differential Gear Oil

NLS00043

1.

Drain oil from drain plug and refill with new gear oil.
(For details, refer to 

RFD-9, "Changing Differential Gear Oil"

 .)

Balancing Wheels (Bonding Weight Type)

NLS00044

REMOVAL

1.

Remove inner and outer balance weights from the road wheel.

CAUTION:

Be careful not to scratch the road wheel during removal.

2.

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

2.

When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install 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) 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 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)

Oil grade and Viscosity:

Refer to

a.

Install balance weight in the position shown in the figure at left.

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 wheel
balancer indication position (angle).

CAUTION:

●

Always use genuine Nissan adhesion balance weights.

●

Balance weights are unreusable; always replace with new
ones.

●

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 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
unbalance values are 5 g (0.17 oz) each or below.

●

If either residual unbalance value exceeds 5 g (0.17 oz), repeat installation procedures.

Tire Rotation

NLS00077

1.

Follow the maintenance schedule for tire rotation service intervals. Refer to 

MA-6, "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 them diagonally by divid-
ing 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-24,

"ID Registration Procedure"
