(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

*1: For further details, refer to MA-10, "SAE Viscosity Number" .
*2: Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and automatic
transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited warranty.
*3: For Canada, NISSAN Automatic Transmission Fluid (ATF), DEXRON
TM III or MERCONTM or equivalent ATF may also be used.
*4: Available in mainland U.S.A. through your INFINITI dealer.
*5: For further details, see “Air conditioner specification label”.
*6: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0° C (32° F).

6. Install the lower glove box in the instrument panel and secure it
with the two hinge pins.
Checking Exhaust SystemINFOID:0000000003533876
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, loose connections, chafing or deterioration.
Checking Automatic Transmission Fluid (ATF)INFOID:0000000003533877
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 selector lever through each gear
position. Shift the selector lever 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 transmission 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.

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.
Checking Disc BrakeINFOID:0000000003533888
