FRONT FOG LAMP
Revision: October 20052005 QX56
Aiming AdjustmentEKS00B9M
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.

See that vehicle is unloaded (except for full levels of coolant,
engine oil and fuel, and spare tire, jack, and tools). Have the
driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Access adjustment screw from underneath front bumper. Turn screw
clockwise to raise pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 200 mm (7.9 in) below the height of
the fog lamp centers as shown.

When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

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 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
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 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
required.

*1: For further details, refer to MA-12, "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 NISSAN new vehicle limited warran ty.
*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 NISSAN 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).
*7: DEXRON
TM III, MERCONTM or equivalent may also be used. Outside the continental United States and Alaska contact a NISSAN
dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRONTM III or MERCONTM Automatic
Transmission Fluid.
