INSPECTION AFTER REMOVAL

Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

●

Frequent engine starts

●

Low ambient temperatures

Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:

●

Extended highway driving

●

Frequent high engine revolution

CAUTION:

●

Do not drop or shock spark plug.

●

Do not use wire brush for cleaning.

●

If plug tip is covered with carbon, spark plug cleaner may
be used.

Checking Exhaust System

NLS0004Y

Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, chafing or deterioration.

●

If anything is found, repair or replace damaged parts.

Checking CVT Fluid

NLS0008N

FLUID LEVEL CHECK

Fluid level should be checked with the fluid warmed up to 50 to 80

C (122 to 176

F). The fluid level check pro-

cedure is as follows:

Check for fluid leakage.

With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20

C (68

F), it takes about 10

minutes for the CVT fluid to warm up to 50 to 80

C (122 to

176

F).

Park the vehicle on a level surface.

Apply parking brake firmly.

With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.

Pull out the CVT fluid level gauge from the CVT fluid charging
pipe after pressing the tab on the CVT fluid level gauge to
release the lock.

Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid
level gauge rotating 180

from the originally installed position,

then securely push the CVT fluid level gauge until it meets the
top end of the CVT fluid charging pipe.

CAUTION:

When wiping away the CVT fluid level gauge, always use
lint-free paper, not a cloth rag.

Place the selector lever in “P” or “N” and make sure the fluid
level is within the specified range.

CAUTION:

When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until it is securely locked.

Check CVT fluid condition.

●

If CVT fluid is very dark or smells burned, check operation of
CVT. Flush cooling system after repair of CVT.

●

If CVT fluid contains frictional material (clutches, brakes, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of CVT. Refer to

CO-13,

"RADIATOR"

and

CVT-17, "CVT Fluid Cooler Cleaning"

Radiator (2)

●

CVT fluid cooler hose (inlet side) (3)

●

Transaxle assembly (4)

Drain CVT fluid from CVT fluid cooler hose (outlet side) (1) and
refill with new CVT fluid at CVT fluid charging pipe with the
engine running at idle speed.

Refill until new CVT fluid comes out from CVT fluid cooler hose
(outlet side) (1).
About 30 to 50% extra fluid will be required for this procedure.

CAUTION:

●

Use only Genuine NISSAN CVT Fluid NS-2. Do not mix with other fluid.

●

Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.

●

When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.

●

Delete CVT fluid deterioration date with CONSULT-II after changing CVT fluid. Refer to

Balancing Wheels (Bonding Weight Type)

NLS00056

REMOVAL

Remove inner and outer balance weights from the road wheel.

CAUTION:

Be careful not to scratch the road wheel during removal.

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.

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

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:
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 grad and Viscosity:

Refer to

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

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 non-reusable; always replace with
new ones.

●

Do not install more than three sheets of balance weight.

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.

Start wheel balancer again.

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.

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

NLS0005T

Do not include the spare tire when rotating the tires.

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.

Perform the ID registration, after tire rotation. Refer to
