ing at a low speed or climbing a gentle
slope, you may feel uncomfortable shift
shocks as the transmission shifts be-
tween 3rd and overdrive repeatedly. In
this case, press the overdrive switch.
The O/D OFF indicator light comes on
at this time.
When driving conditions change, press the over-
drive switch again. The O/D OFF indicator light
goes out.
Remember not to drive at high speeds for ex-
tended periods of time with the O/D OFF light
illuminated. This reduces the fuel economy.
Fail-safeWhen the Fail-safe operation occurs, the next
time the key is turned to the ON position, the
O/D OFF light will blink for approximately 8
seconds after coming on for 2 seconds. While
the vehicle can be driven under these circum-
stances please note that the gears in the auto-
matic transmission may be locked in third gear.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the Fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition key
OFF and wait for 3 seconds. Then turn thekey back to the ONposition. The vehicle
should return to its normal operating con-
dition. If it does not return to its normal
operating condition have your NISSAN
dealer check the transmission and repair if
necessary.

This occurs because the transfer clutch
is released and not because of a mal-
function.
CAUTION

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
while driving on steep downhill
grades. Use the engine brake.

Do not operate the 4WD shift switch
with the rear wheels spinning.

Before placing the 4WD shift switch
in the 4H position from 2WD or
AUTO, ensure the vehicle speed is
less than 50 MPH (80 km/h). Failure
to do so can damage the 4WD sys-
tem.

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

Engine idling speed is high whilewarming up the engine. Be especially
careful when starting or driving on
slippery surfaces with the 4WD shift
switch set in AUTO.
4WD shift indicator lightThe 4WD shift indicator light is located in the
tachometer.
The light should turn off within 1 second after
turning the ignition switch to ON.
While the engine is running, the 4WD shift
indicator light will illuminate the position se-
lected by the 4WD shift switch.

The 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light will
come on. If the indicator light does not

Part time 4WD models:

If the ATP light is ON, this indicates
that the automatic transmission P
(park) position will not function and
the transfer shift lever is in the N
position. Failure to engage the trans-
fer shift lever in H or 4L could result
in the vehicle moving unexpectedly,
resulting in serious personal injury or
property damage.
All-mode 4WD models:

If the ATP light is ON, this indicates
that the automatic transmission P
(park) position will not function and
the transfer case is in neutral. Make
sure that the 4WD shift indicator light
(and transfer 4LO position indicator)
light remains illuminated before
stopping the engine. Otherwise, the
vehicle could unexpectedly move
even if the automatic transmission is
in the P (park) position.
3. To help prevent the vehicle rolling into the
street when parked on a sloping drive way, itis a good practice to turn the wheels as
illustrated.

HEADED DOWNHILL WITH CURB:
1
Turn the wheels into the curband move the
vehicle forward until the curbside wheel
gently touches the curb.

HEADED UPHILL WITH CURB:
2
Turn the wheels away from the curband
move the vehicle back until the curb side
wheel gently touches the curb.

HEADED UPHILL OR DOWNHILL, NO
CURB:
3
Turn the wheels toward the side of the road
so the vehicle will move away from the center
of the road if it moves.
Make sure the ATP light is off before stop-
ping the engine.
4. Turn the ignition key to the LOCK position
and remove the key.The power assisted steering is designed to use
a hydraulic pump, driven by the engine, to assist
steering.
If the engine stops or drive belt breaks, you will
still have control of the vehicle. However, much
greater steering effort is needed, especially in
sharp turns or at low speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be much harder to operate.POWER STEERING

extra care is required while driving.
If a tire slips on rough roads for more than
10 seconds, the ABS brake warning light
may come on. Turn OFF the ignition key,
restart the engine and drive the vehicle at
speeds above 20 MPH (30 km/h). If the
warning light does not go out, have the
vehicle checked at a NISSAN dealer.Self-test featureThe anti-lock brake system consists of electronic
sensors, electric pumps, and hydraulic solenoids
controlled by a computer. The computer has a
built-in diagnostic feature that tests the system
each time you start the engine and move the
vehicle at a low speed in forward or reverse.
When the self-test occurs, you may hear a clunk
noise and/or feel a pulsation in the brake pedal.
This is normal and is not an indication of any
malfunction. If the computer senses any mal-
function, it switches the anti-lock brake system
OFF and turns on the ABS brake warning light in
the dashboard. The brake system will then be-
have normally, but without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair at your
earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. Stopping distances may also be
longer on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from
the vehicle in front of you. Ultimately,
the responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition of tires may also
affect braking effectiveness.

When replacing tires, install the
specified size of tires on all four
wheels.

When installing a spare tire, make
sure it is the proper size and type asspecified on the tire placard. See
“Tire placard” in the “9. Technical and
consumer information” section for
tire placard location information.

TOWING RECOMMENDED BY
NISSAN
Two wheel drive modelsNISSAN recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed truck as
illustrated.
CAUTION

Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward), as this may
cause serious and expensive damage
to the transmission. If it is necessary
to tow the vehicle with the front
wheels raised, always use towing
dollies under the rear wheels.

When towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:

Turn the ignition key to the OFF
position, and secure the steeringwheel in a straightahead position
with a rope or similar device. Never
secure the steering wheel by turn-
ing the ignition key to the LOCK
position. This may damage the
steering lock mechanism.

If you have to tow manual transmis-
sion models with the rear wheels on
the ground or four wheels on the
ground (if you do not use towing
dollies):

Always release the parking brake.

Move the transmission shift lever
to the N(Neutral) position.

Observe the following restricted tow-
ing speeds and distances for manual
transmission models only:

Speed: Below 60 MPH (95 km/h)

Distance: Less than 500 miles (800
km)
If the speed or distance must necessarily be
greater, remove the propeller shaft before tow-
ing to prevent damage to the transmission.

ing and driving” section for exhaust gas (carbon
monoxide).
Underbody:
The underbody is frequently exposed to corro-
sive substances such as those used on icy roads
or to control dust. It is very important to remove
these substances, otherwise rust will form on the
floor pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the under-
body should be thoroughly flushed with plain
water, being careful to clean those areas where
mud and dirt may accumulate. For additional
information, see “Cleaning exterior” in the “7.
Appearance and care” section.
Fluid leaks:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been
parked for a while. Water dripping from the air
conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING

Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the selector lever to the P
(Park) position.

Be sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.

If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.

It is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.

Always wear eye protection when-
ever you work on your vehicle.

If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.

Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.

Keep smoking materials, flame and
sparks away from fuel and battery.

Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the OFF
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable be-
fore working near the fan.
