or
Brake warning light
This light functions for both the parking brake
and the foot brake systems.
Parking brake indicator:
The light comes on when the parking brake is
applied.
Low brake fluid warning light:
When the ignition key is in the ON position, the
light warns of a low brake fluid level. If the light
comes on while the engine is running, stop the
vehicle and perform the following:
1. Check the brake fluid level. Add brake fluid as
necessary. See “Brake and clutch fluid” in the
“8. Maintenance and do-it-yourself” section.
2. If the brake fluid level is correct:
Have the warning system checked by a NISSAN
dealer.
WARNING

Your brake system may not be work-
ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for re-
pairs. Otherwise, have your vehicle
towed.

Pressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your stop-
ping distance and braking will re-
quire greater pedal effort as well as
greater pedal travel.

If the brake fluid level is below the
MINmark on the brake fluid reser-
voir, do not drive until the brake sys-
tem has been checked at a NISSAN
dealer.
Charge warning light
If the light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and checkthe alternator belt. If the belt is loose, broken,
missing or if the light remains on, see your
NISSAN dealer immediately.
CAUTION
Do not continue driving if the belt is
loose, broken or missing.
Door open warning light
This light comes on when any of the doors
and/or rear window are not closed securely
while the ignition key is ON.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If the
light flickers or comes on during normal driving,
pull off the road in a safe area, stop the engine
immediatelyand call a NISSAN dealer or other
authorized repair shop.
The oil pressure warning light is not de-
signed to indicate a low oil level. Use the
dipstick to check the oil level.See “Engine

CAUTION
Running the engine with the oil pres-
sure warning light on could cause seri-
ous damage to the engine almost imme-
diately. Turn off the engine as soon as it
is safe to do so.
4WD warning light (model)
The four wheel drive warning light comes on
when the key switch is turned to ON. It turns off
soon after the engine is started.
If the engine or vehicle is not functioning prop-
erly, the warning light will either remain illumi-
nated or blink. See “4WD warning light” in the
“5. Starting and driving” section.
CAUTION

If the warning light comes on or
blinks during operation, have your
vehicle checked by an authorized
NISSAN dealer as soon as possible.
Do not drive on dry hard surface
roads in the 4H or 4LO position. If the
4WD warning light turns on when you
are driving on dry hard surface roads

in the AUTO or 4H position, shift
the 4WD shift switch to 2WD.

in the 4LO position, stop the ve-
hicle, move the automatic trans-
mission lever to the Nposition,
and shift the 4WD shift switch to
2WD.
If the warning light is still on after the
above operation, have your vehicle
checked by an authorized NISSAN
dealer as soon as possible.
Low fuel warning light
This light comes on when the fuel in the tank is
getting low. Refuel as soon as it is convenient,
preferably before the fuel gauge reaches E.
There will be a small reserve of fuel re-
maining in the tank when the fuel gauge
needle reaches E.
Low tire pressure warning light
(if so equipped)
This light warns of a low tire pressure.
NISSAN’s low tire pressure warning system is a
tire pressure monitoring system. It monitors tire
pressure of all tires except the spare.
When the tire pressure monitoring system warn-
ing light is lit, one or more of your tires is
significantly under-inflated. You should stop and
check your tires as soon as possible, and inflate
them to the proper pressure as indicated on the
vehicle’s tire information placard. Driving on a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Each tire, including
the spare, should be checked monthly when
cold and set to the recommended inflation pres-
sure as specified in the vehicle placard and
owner’s manual.
The recommended inflation pressure may also
be found on the Tire and Loading Information
label.
Low tire pressure warning:
If the vehicle is being driven with low tire pres-
sure, the light will illuminate. Also a chime will
sound for about 10 seconds.

Make sure the area around the vehicle is
clear.

Check fluid levels such as engine oil, coolant,
brake and clutch fluid, window washer fluid
as frequently as possible, at least whenever
you refuel.

Check to be sure that all windows and light
lenses are clean.

Visually inspect tires for their appearance and
condition. Also check tires for proper infla-
tion.

Lock all doors.

Position seat and adjust head restraints.

Adjust inside and outside mirrors.

Fasten seat belts and ask all passengers to
do likewise.

Check the operation of warning lights when
key is turned to the ON (3) position.1. Apply the parking brake.
2.Automatic transmission:
Move the selector lever to P (Park position) or
N (Neutral position). (P preferred)
The selector lever cannot be moved out
of P and into any of the other gear
positions if the ignition key is turned to
LOCK or if the key is removed from the
switch.
The starter is designed not to operate if
the selector lever is in one of the driving
positions.
Manual transmission:
Move the gearshift lever to N (Neutral posi-
tion), and depress the clutch pedal to the
floor while starting the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Crank the enginewith your foot off the
accelerator pedalby turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but fails to
run, repeat the above procedure.

If the engine is very hard to start in extremely
cold weather or when restarting, depress theaccelerator pedal a little (approximately 1/3
to the floor) and hold it then crank the engine.
Release the key and the accelerator pedal
when the engine starts.

If the engine is very hard to start because it is
flooded, depress the accelerator pedal all the
way to the floor and hold it. Crank the engine
for 5 to 6 seconds. After cranking the engine,
release the accelerator pedal. Crank the en-
ginewith your foot off the accelerator
pedalby turning the ignition key to START.
Release the key when the engine starts. If the
engine starts, but fails to run, repeat the
above procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, turn the key off and wait 10
seconds before cranking again, other-
wise the starter could be damaged.
4.Warm-up
Always allow the engine to idle for at least 30
seconds after starting. Do not race the en-
gine while warming it up. Drive at moderate
speed for a short distance first, especially in

*1:
The transfer 4LO position indicator light
may blink. Stop the vehicle. Be sure to
shift the 4WD shift switch after the auto-
matic transmission lever has been shifted
to the N position. If the indicator light
keeps blinking after the 4WD shift proce-
dure in the previous page, drive slowly
without abrupt maneuvers for a while.
Then the light will turn on or off.

Avoid making a turn or abrupt starts while
shifting to 4LO. Otherwise gears may
grind, damaging the drive system.
*2: Make sure the transfer 4LO position indicator
light turns on when you shift the 4WD shift
switch to 4LO.
The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of drive
modes available, AUTO, 2WD, 4H and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H
and 4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and
the automatic transmission selector lever
is in the Nposition when changing into or
out of 4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make
sure that the 4WD shift indicator light is
on and the ATP warning light goes off.
Otherwise, the vehicle could unexpect-
edly move even if the automatic trans-
mission is in the P position.
CAUTION

Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.

The 4H position provides greater
power and traction. Avoid excessive
speed, as it will cause increased fuel
consumption and higher oil tempera-
ture, and could damage drivetrain
components. Speeds over 50 MPH
(80 km/h) in 4H are not recom-
mended.

The 4LO position provides maximum
power and traction. Avoid raising ve-hicle speed excessively, as the maxi-
mum speed is approximately 30 MPH
(50 km/h).

When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or revers-
ing.

Do not shift the 4WD shift switch
(between 2WD, AUTO and 4H) while
driving on steep downhill grades. Use
the engine brake.

Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with
the rear wheels spinning.

Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surfaces in 4H or 4LO
may cause unnecessary noise and
tire wear. We recommend driving in
the 2WD or AUTO position under
these conditions.

Vehicles equipped with a limited slip
differential (LSD) have improved driv-

oil and coolant. Improperly disposed
engine oil, engine coolant, and/or
other vehicle fluids can hurt the envi-ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This section gives instructions regarding only
those items which are relatively easy for an
owner to perform. More involved service should
be done by your NISSAN dealer.
A genuine NISSAN Service Manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “9. Technical and con-
sumer information” section.
You should be aware that incomplete or im-
proper servicing may result in operating difficul-
ties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, have it done by your NISSAN
dealer.8-6

3. Open the air release plug(s) to drain the
coolant.
4. Flush the cooling system by running fresh
water through the radiator.

Waste coolant must be disposed of
properly.

Check your local regulations.
5. Close the radiator drain plugs and engine
block drain plugs securely.
6. See the “9. Technical and consumer informa-
tion” section for cooling system capacity.
Fill the radiator slowly with the proper mixture
of coolant and water. Fill the reservoir tank
slowly up to the MAX level. Then install the
radiator cap and close the air release plug(s).
7. Start the engine and warm it up until it
reaches normal operating temperature. Then
race the engine 2 or 3 times under no load.
Watch the coolant temperature gauge for
signs of overheating.
8. Stop the engine. After it completely cools
down, refill the radiator up to the filler open-
ing. Fill the reservoir tank up the MAX level.
9. Check the radiator drain plug and engine
block drain plugs for any sign of leakage.
CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and apply
