(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace drive belts if damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, go to the FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are

5. Start wheel balancer. Make sure that inner and outer residual imbalance values are 5 g (0.18 oz) each or
below.
Wheel Balance (Maximum Allowable Imbalance)
• If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.
Tire RotationINFOID:0000000003533885
1. Rotate the tires on each side from front to back as shown.
2. Adjust the tire pressure to specification. Refer to WT-28, "
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 Fluid Level and LeaksINFOID:0000000003533886
• Check the brake fluid level in the reservoir tank. It should be
between the “MAX” and “MIN” lines 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.
CheckingBrake Line and CablesINFOID:0000000003533887
1. Check the brake lines and hoses for cracks, deterioration, and
other damage. Replace any damaged parts.
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.
