6. Install the lower glove box in the instrument panel and secure it
with the two hinge pins.
Checking Exhaust SystemINFOID:0000000001606180
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, loose connec tions, chafing or deterioration.
Checking Automatic Transmission Fluid (ATF)INFOID:0000000001606181
1. Remove the ATF level gauge bolt.
2. Before driving, the ATF level can be checked at ATF tempera-
tures of 30 ° to 50 °C (86° to 122° F) using the “COLD” range on
the ATF level gauge as follows:
a. Park the vehicle on a level surface and set the parking brake.
b. Start the engine and move the shift selector through each gear position. Move the shift selector into the “P” position.
c. Check the ATF level with the engine idling.
d. Remove the ATF level gauge and wipe it clean with a lint-free paper.
CAUTION:
When wiping the ATF from the ATF level gauge, always use
a lint-free paper, not a cloth.
e. Re-insert the ATF level gauge into the charging pipe until the cap contacts the top of the charging pipe as shown.
CAUTION:
To check ATF level, insert the ATF level gauge until the cap
contacts the top of the charging pipe, with the gauge
reversed from the normal inserted position.
f. Remove the ATF level gauge and note the ATF level. If the ATF level is at low side of range, add ATF to the transmission
through the charging pipe.
CAUTION:
Do not overfill the tr ansmission with ATF.
g. Install the ATF level gauge and the ATF level gauge bolt.
3. Warm up the engine.
4. Check for any ATF leaks.

7. Start balancer machine. Make sure that inner and outer residual imbalance values are 5 g (0.17 oz) each
or below.
8. If either residual imbalance value exceeds 5 g (0.17 oz), repeat installation procedures.
TIRE ROTATION
• Follow the maintenance schedule for tire rotation service intervals.
Refer to MA-6, "
General Maintenance".
• When installing the wheel, tighten wheel nuts to the specified
torque.
CAUTION:
• 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 nuts for aluminum wheels.
Tire RotationINFOID:0000000001606189
1. Rotate the tires on each side from front to back as shown.
2. Adjust the tire pressure to specification. Refer to WT-51, "
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 a wheel
and tire have been installed such as after repairing a flat tire.
Checking Brake Flui d Level and LeaksINFOID:0000000001606190
• Check the brake fluid level in the reservoir tank. It should be
between the “MAX” and “MIN” li nes on the reservoir tank.
• If the fluid level is extremely low, check the brake system.
• If the brake warning lamp comes on when the fluid is at the correct
level, check the brake fluid level switch and the parking brake
switch.

balance Refer to WT-46, "

CAUTION:
If brake fluid leaks are visible around the brake line joints,
retighten the joint, or replace damaged parts as necessary.
2. Check for brake fluid leaks by fully depressing brake pedal while engine is running.
