come on immediately, make sure the
area around the vehicle is safe, and
drive the vehicle straight, accelerate or
decelerate or move the vehicle in re-
verse, then shift the 4WD shift switch.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out.
CAUTION
When the 4WD shift switch is turned
to the AUTO position at low ambient
temperatures, the 4WD shift indicator
light may show 4H. If this happens,
all four wheels are driven as torque
distribution is in the 4H position. Be
careful as the vehicle may become
difficult to turn. When the vehicle is
driven, the 4WD shift indicator light
should change to AUTO.
If the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the AUTO or
4H position at low ambient tempera-
tures, the 2WD mode may be being
engaged due to malfunctioning drivesystem. If the indicator does not re-
turn to normal and the 4WD warning
light comes on, have the system
checked by the nearest NISSAN
dealer.
4WD warning lightThe 4WD warning light is located in the meter.
The 4WD warning light comes on when the key
switch is turned to ON. It turns off soon after the
engine is started.

If any malfunction occurs in the 4WD system
when the key switch is ON, the warning light will
either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
indicator light goes out.
High-temperature transfer case oil makes the
warning light blink rapidly (about twice per sec-
ond). If the warning light blinks rapidly during
operation, stop the vehicle in a safe place imme-
diately. Then if the light goes off after a while, you
can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning light
blink slowly (about once per two seconds).
Change the 4WD shift switch into 2WD and do
not drive fast.
CAUTION
If the warning light comes on or
blinks slowly during operation or rap-
idly after stopping the vehicle for a
while, have your vehicle checked by
an authorized NISSAN dealer as
soon as possible.
Shifting between 4H and 4LO is notrecommended when the 4WD warn-
ing light turns on.
When the warning light comes on,
the 2WD mode may be engaged even
if the 4WD shift switch is in AUTO or
4H. Be especially careful when driv-
ing. If corresponding parts are mal-
functioning, the 4WD mode will not
be engaged even if the 4WD shift
switch is shifted.
Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surface roads in 4H or
4L may cause unnecessary noise, tire
wear and increased fuel consump-
tion.
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.
The transfer case may be damaged if
you continue driving with the warning
light blinking rapidly.

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

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakeThe brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.Using the brakesAvoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out
the brake linings and pads faster and reduce gas
mileage.
To help save the brakes and to prevent the
brakes from overheating, before going down a
slope or long grade, reduce speed and down-
shift to a lower gear.Wet brakesWhen the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.To dry brakes, drive the vehicle at a safe speed
while lightly pressing the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
WARNING
While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.
If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
at each wheel so the wheels will not lock when
braking abruptly or when braking on slippery
surfaces. The system detects the rotation speed
at each wheel and varies the brake fluid pressure
to prevent each wheel from locking and sliding.
By preventing wheel lockup, the system helpsthe driver maintain steering control and helps to
minimize swerving and spinning on slippery sur-
faces.
Using the systemDepress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Normal operationThe anti-lock brake system will not operate at
speeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more wheels
are close to locking up, the actuator (under the
hood) rapidly applies and releases hydraulic
pressure (like pumping the brakes very quickly).
While the actuator is working, you may feel a
pulsation in the brake pedal and hear a noise or
vibration from the actuator under the hood. This
is normal and indicates that the anti-lock system
is working properly. However, the pulsation may
indicate that road conditions are hazardous and

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.

When driving on slippery surfaces or suddenly
avoiding obstacles on roads, the vehicle might
swerve or slip. With the vehicle dynamic control
(VDC) system, sensors detect these movements
and control the braking and engine output to
help improve vehicle stability while driving.
When the vehicle dynamic control system is
operating, the slip indicator in the instrument
panel blinks.
When only the traction control system portion
of the vehicle dynamic control system is
operating, the slip indicator will also blink.
If the slip indicator blinks, the vehicle is under
slippery conditions. Be sure to drive carefully.
See “Slip indicator light”, and “Vehicle dy-
namic control off indicator light” in the “2.
Instruments and controls” section.
Indicator light
If a malfunction occurs in the system, the
SLIP and
indicator lights come on in
the meter panel.
As long as these warning lights are on, the
traction control function is canceled.
If the vehicle is operated with the vehicle dy-
namic control system turned off, all VDC func-
tions will be turned off. The brake LSD and ABS
system will still operate with the VDC system off.
VDC is provided the “Brake Limited Slip Differ-ential” system. The Brake LSD system works
when the one of driving wheels is spinning on a
slippery surface. The Brake LSD system brakes
the spinning driving wheel, then distributes the
driving power to the another. While the Brake
LSD system or the ABS system is activated, the
slip indicator light will blink and you may feel a
pulsation in the brake pedal and hear operation
sound. This is normal.
While the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise or
vibration from under the hood. This is normal and
indicates that the VDC system is working prop-
erly.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in
reverse at a slow speed. 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 a malfunction.
WARNING
The vehicle dynamic control system
is designed to help improve driving
stability but does not prevent acci-
dents due to abrupt steering opera-tion at high speeds or by careless or
dangerous driving techniques. Re-
duce vehicle speed and be especially
careful when driving and cornering
on slippery surfaces and always drive
carefully.
If suspension parts such as shock
absorbers, struts, springs and bush-
ings are not standard equipment or
are extremely deteriorated, the ve-
hicle dynamic control off indicator
light may come on.
When driving on extremely inclined
surfaces such as higher banked cor-
ners, the vehicle dynamic control sys-
tem may not operate properly or the
vehicle dynamic control off indicator
light may come on. Do not drive on
these types of roads.
If the tires other than the recom-
mended ones are used, the vehicle
dynamic control system may not op-
erate properly or the vehicle dynamic
control off indicator light may come
on.

LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)The low tire pressure warning system monitors
tire pressure of all wheels (except the spare tire).
If the vehicle is being driven with very low tire
pressure (lower than 25 psi, 171 kPa), the low
tire pressure warning system will activate and
warn you of it by the low tire pressure warning
light. This system will activate only when the
vehicle is driven at speeds above 20 MPH (32
km/h). For more details, please refer to
“Warning/indicator lights and audible remind-
ers” in the “2. Instruments and controls” section,
and “Low tire pressure warning system” in the
“5. Starting and driving” section.
WARNING
If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-jury. Check the tire pressure for all
four wheels and adjust the pressure
to the COLD tire pressure shown on
the tire placard. If you have a flat tire,
replace it with a spare tire as soon as
possible.
When a spare tire is mounted or a
wheel is replaced, the low tire pres-
sure warning system will not func-
tion. Contact your NISSAN dealer as
soon as possible for tire replacement
and/or system resetting.
Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CHANGING A FLAT TIREIf you have a flat tire, follow the instructions
below.Stopping the vehicle1. Safely move the vehicle off the road away
from traffic.
2. Turn on the hazard warning flasher.3. Park on a level surface and apply the parking
brake. Shift the manual transmission into
reverse (automatic transmission in P).
WARNING
The transfer control lever
must be in the 2H, 4H or 4L position.
Never place the transfer control lever
in the Nposition. Otherwise, the ve-
hicle could roll unexpectedly even if
the manual transmission is in gear or
the automatic transmission is in the
P position. This could result in seri-
ous personal injury or property dam-
age.
All-mode 4WD models:
Make sure the 4WD shift indicator
and/or transfer 4LO position indica-
tor light remains illuminated before
stopping the engine.
Make sure the ATP light is off before
stopping the engine. Otherwise, the

Wheel nuts*:
When checking the tires, make sure no nuts are
missing, and check for any loose nuts. Tighten if
necessary.
Tire rotation*:
Tires should be rotated every 7,500 miles
(12,000 km). However, the timing for tire rotation
may vary according to your driving habits and
road surface conditions.
Wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there may
be a need for wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information booklet.
