PERIODIC MAINTENANCEPFP:00026
Introduction of Periodic MaintenanceELS001BJ
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 time intervals, whichever comes first.
Maintenance For Off-road Driving (4WD only)ELS001BK
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 1ELS001BL
EMISSION CONTROL SYSTEM MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. [ ]: At the mileage intervals only
Schedule 1
Follow 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
remaining 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-

(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 da maged.
(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 inter vals are
required.

Wheel Balance (Maximum Allowable Imbalance)

If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.
Tire RotationELS001H5
1. Rotate the tires on each side from front to back as shown.
2. Adjust the tire pressure to specification. Refer to WT-38, "
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 LeaksELS001CA

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 cor-
rect level, check the brake fluid level switch and the parking
brake switch.
Checking Brake Lines and CablesELS001CB
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 BrakeELS001CC
ROTOR
Check the rotor condition for wear or damage. Refer to BR-32,
"Front Disc Brake" , BR-33, "Rear Disc Brake" .
Maximum allowable imbalance Dynamic (At rim flange)
5 g (0.18 oz) (one side)
Static 10 g (0.35 oz)
Wheel nuts : Refer to WT-6, "WHEEL AND TIRE
ASSEMBLY" .

PEDAL STROKE

When parking brake pedal is operated with the specified force, 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 properly, 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 DI-32, "Wir-
ing Diagram — WARN —" .
ADJUSTMENT
1. Remove the lower instrument panel LH. Refer to IP-13, "INSTRUMENT LOWER COVER LH" .
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 Tool.
6. Transfer measurement less 0.6 mm to the parking brake shoes and adjust accordingly.
7. Using wheel nuts, secure the disc 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.
12. Install the lower instrument panel LH. Refer to IP-13, "
INSTRU-
MENT LOWER COVER LH" .
