Introduction of Periodic MaintenanceINFOID:0000000003776980
Two different maintenance schedules are provided, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage or ti me intervals, whichever comes first.
Maintenance for Off-road Driving (4WD only)INFOID:0000000003776981
After driving the vehicle off-road through sand, mud, or water; more frequent maintenance may be required for
the following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters

Schedule 1Follow Periodic Maintenance Schedule 1 if your driving habits frequently includes
one or more of the following driving conditions:
• Repeated short trips of less than 5 miles (8 km).
• Repeated short trips of less than 10 miles (16 km) with outside temperatures re-
maining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi
or door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy, or salt spread roads.
• Towing a trailer or using a car-top carrier. Emission Control Sys-

PERIODIC MAINTENANCE
(1) If towing a trailer, or using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every 30,000 miles
(48,000 km) or 24 months. Using automatic transmission fluid other than Genui ne NISSAN Matic S ATF or 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.
(2) Refer to “Tire rotation” unde r the “General maintenance” heading earlier in this section.

*1: For further details, refer to MA-13, "Engine Oil Recommendation".
*2: If Genuine NISSAN Matic S ATF is not available, Genuine Matic J ATF may also be used. Using automatic transmission fluid
other than Genuine NISSAN Matic S ATF or Matic J ATF will cause deterioration in drivability and automatic transmission dura-
bility, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited warranty.
*3: DEXRON
TM VI type ATF may also be used.
*4: Available in mainland U.S.A. through an INFINITI dealer.
*5: For further details, see “Air conditioner specification label”.
*6: For hot climates, viscosity SAE 90 is suitable for ambient te mperatures above 0° C (32 ° F).
*7: For improved vehicle performance, INFINITI recommends the use of unleaded premium gasoline with an octane rating of at leas t 91
AKI (RON 96). For further details, refer to GI-27, "
Precaution for Fuel (Unleaded Premium Gasoline Recommended)",
*8: See an INFINITI dealer for service for synthetic oil.

Checking the A/T Fluid (ATF)INFOID:0000000004215539
CAUTION:
If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to
MA-8, "
Introduc-
tion of Periodic Maintenance".
1. Before driving, the A/T fluid level can be checked at A/T fluid temperatures of 30 ° to 50 ° C (86 ° to 122° F) using the “COLD”
range on the A/T fluid level gauge as follows:
a. Park the vehicle on a level surface and set the parking brake.
b. Start the engine and move the A/T shift selector through each gear position. Shift the A/T shift selector into the “P” position.
c. Check the A/T fluid level with the engine idling.
d. Remove the A/T fluid level gauge and wipe it clean with a lint- free paper.
CAUTION:
When wiping the A/T fluid from the A/T fluid level gauge,
always use a lint-free paper, not a cloth.
e. Re-insert the A/T fluid level gauge into the A/T fluid charging pipe until the cap contacts the top of the A/T fluid charging pipe
as shown.
CAUTION:
To check A/T fluid level, insert th e A/T fluid level gauge until
the cap contacts the top of the A/T fluid charging pipe, with
the gauge reversed from the normal inserted position.
f. Remove the A/T fluid level gauge and note the A/T fluid level. If the A/T fluid level is at low side of range, add A/T fluid to the
transmission through the A/T fluid charging pipe.
CAUTION:
Do not overfill the tran smission with A/T fluid.
g. Install the A/T fluid level gauge and the A/T fluid level gauge bolt.
2. Warm up the engine and transmission.
3. Check for any A/T fluid leaks.
4. Drive the vehicle to increase the A/T fluid temperature to 80 ° C (176 ° F).
5. Allow the A/T fluid temperature to fall to approximately 65 °C (149° F). Use the CONSULT-III to monitor the
A/T fluid temperature as follows:

Checking Brake Fluid Level and Leaks
INFOID:0000000003777006
• 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.
• Visually check around reservoir tank for fluid leaks.
Checking Brake Line and CablesINFOID:0000000003777007
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:0000000003777008
ROTOR
Check the rotor condition for wear or damage. Refer to BR-7, "DISC
ROTOR : Inspection" , BR-9, "DISC ROTOR : Inspection" .

• Check the steering column connections for looseness.
STEERING LINKAGE
• Check the ball joint, dust cover and other component parts for looseness, wear, damage, and grease leak-
age.
Checking Power Steering Fluid and LineINFOID:0000000003777010
CHECKING FLUID LEVEL
• Check the power steering fluid level with the engine off.
• Check fluid level on reservoir. Use “HOT” range at fluid tempera- tures of 50 ° to 80° C (122° to 176° F). Use “COLD” range at fluid
temperatures of 0 ° to 30° C (32° to 86° F).
CAUTION:
• Do not overfill.
• Refer to MA-12, "
Fluids and Lubricants" .
CHECKING LINES
• Check lines for improper attachment, leaks, cracks, damage, loose
connections, chafing, and deterioration.
