General MaintenanceELS000AL
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing the spare, and adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate prop-
erly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch keeps the hood from opening when the primary latch is
released.
When driving in areas using road salt or other corrosive materials, check for
lubrication frequently.BL-4
,BL-8
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-38
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.SB-3

CHECKING COOLING SYSTEM FOR LEAKS
lTo check for leakage, apply pressure to the cooling system with
atester.
WA RN ING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
Checking Fuel LinesELS000AQ
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration. If nec-
essary, repair or replace faulty parts.
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber hose clamps.
Ensure that screw does not contact adjacent parts.

lCheck radiator cap relief pressure.
lWhen connecting the radiator cap to the tester, apply water or
LLC to the cap seal part.
lReplace the radiator cap if there is an unusualness in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.

lTo check for leakage, apply pressure to the cooling system with
atester.
WAR NIN G:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.

REAR SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service
EES0007F
Check axle and suspension parts for excessive play, wear, and damage.
lMove rear wheels (RH/LH) to check abnormal free play.
lRetighten all nuts and bolts to the specified torque.
lCheck strut for oil leakage and damage.
Wheel AlignmentEES0007G
DESCRIPTION
lMeasure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check strut operation.
5. Check each mounting point of axle and suspension for looseness and deformation.
6. Check each link and arm for cracks, deformation, and other damage.
7. Check the vehicle posture.
CAMBER
Camber is preset at factory and cannot be adjusted.
lIf the camber is not within specification, inspect and replace any damaged or worn rear suspension parts.
TOE-IN
Measure toe-in using the following procedure.
lAlways perform following procedure on a flat surface.
lMake sure that no person is in front of the vehicle before push-
ing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tires at the
same height as hub center.this mark is a measuring points.

ALL MODE 4X4 SYSTEM
4WD MODE SWITCT
AUTO mode (AUTO indicator lamp ON)
lElectronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
lMakes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
lOn roads which do not require 4WD, it contributes to improved fuel economy by driving in conditions close
to front-wheel drive.
lSensors determine the vehicle's turning condition, and in response tight cornering/braking are controlled
by distributing optimum torque to rear wheels.
NOTE:
lWhen driving in AUTO mode or LOCK mode, if there is a large difference between front and rear wheel
speed which continues for a long time, oil temperature of drive system parts becomes too high and 4WD
warning lamp flashes rapidly. (When 4WD warning lamp flashes, vehicle changes to front-wheel drive
conditions.)
lWhen driving in AUTO mode, 4WD warning lamp may flash slowly if there is a significant difference in
pressure or wear between tires. At this time, vehicle performance is not fully available and cautious driving
is required. (Continues until engine is turned OFF.)
lIf 4WD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AUTO mode will be restored.
lIf the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
lWhen the difference of revolution speed between the front and rear wheel with AUTO mode the shift
switch occasionally changes to LOCK mode automatically. This is not malfunction.
LOCK mode (LOCK indicator lamp and AUTO indicator lamp ON)
lFront/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.
lWhen LOCK mode is selected, vehicle will switch automatically to AUTO mode if vehicle speed increases.
If vehicle speed then decreases, the vehicle automatically returns to direct 4-wheel driving conditions.
NOTE:
If there is a significant difference in pressure or wear between tires, full vehicle performance is not available.
Tire conditions are detected, and LOCK mode may be prohibited, or else speeds at which LOCK mode is
enabled may be restricted.
2WD mode (indicator lamps OFF)
Vehicle is in front-wheel drive.
NOTE:
lIf front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties for
the system.
lThe shift switch even if the shift switch is in 2WD mode, the sift switch occasionally automatically change
to 4WD mode depending on the driving condition (For example; Depressing the acceleration firmly). this is
not malfunction. How ever, 4WD mode indicator lamp dose not illuminate.
4WD WARNING LAMP
Turns ON when there is a malfunction in 4WD system. It indicates that fail-safe mode is engaged and vehicle
is in 2WD.
Also turns ON when ignition switch is turned ON, for purpose of bulb check. Turns OFF approximately for 3
seconds after the engine starts if system is normal.
