PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000005145934
Two different maintenance schedules are provi
ded, 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:0000000005145935
Whenever you drive off-road through sand, mud, or wa ter; 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 the 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) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading reaches the maximum limit.
(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) Periodic maintenance is not required. However, 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
required.

(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 Ge nuine NISSAN Matic S ATF or Matic J ATF will cause
deterioration in drive ability 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” under the “General maintenance” heading earlier in this section.

RUNOUT
1. Attach disc rotor to wheel hub using wheel nuts (at two or more
positions).
2. Inspect runout using a dial gauge placed at 10 mm (0.39 in) inside the disc edge.
NOTE:
Before measuring, make sure that wheel bearing axial end play
is within the specification. Refer to RAX-6, "
On-Vehicle Inspec-
tion and Service".
3. When runout exceeds limit value, displace mounting positions of disc rotor by one hole. And then find a position of the minimum value for runout.
4. If runout is outside the specified value after performing the above operation, turn disc rotor using Tool.

PEDAL STROKE
• When parking brake pedal is operated with the specified forc e, make sure the stroke is within the specified
number of notches. Check by listening and counting the ratchet clicks.
INSPECTION
• Make sure the components are attached pr operly, checking for looseness or backlash.
• Check parking brake pedal assembly for bends, damage and cracks, and replace if necessary.
• Check cable for wear and damage, and replace if necessary.
• Check parking brake warning lamp switch for malfunction, and replace if necessary. Refer to BCS-38, "
Diag-
nosis Procedure".
ADJUSTMENT
1. Remove the lower instrument panel LH. Refer to IP-14, "Exploded View".
2. Partially engage parking brake pedal to access adjusting nut.
3. Insert a deep socket wrench to rotate adjusting nut and loosen cable sufficiently. Then, disengage the parking brake pedal.
4. Remove the wheel and tire using power tool.
5. Remove the disc rotor and measure inner diameter at widest point using suitable tool.
6. Transfer measurement less 0.6 mm (0.024 in) to the parking brake shoes and adjust accordingly.
7. Using wheel nuts, secure the disc rotor to the hub to prevent it from tilting.
8. Rotate the disc rotor to make sure there is no drag.
9. Adjust cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg-f, 110 lb-f).
b. Rotate adjusting nut with deep socket to adjust pedal stroke to specification.
c. With parking brake pedal completely disengaged, make sure there is no drag on the parking brake.
10. Install the disc rotor.
11. Install the wheel and tire using power tool. Pedal stroke : Refer to
PB-12, "
Parking Brake Control".
