ing performance on rough roads.
They have increased traction perfor-
mance, so when making a turn on
paved roads, vibration and tire
squealing may occur.
The 4WD transfer case may not be
shifted between 4H and 4LO at low
ambient temperatures and the trans-
fer 4LO position indicator light may
blink even when the 4WD shift switch
is shifted. After driving for a while
you can change the 4WD transfer
case between 4H and 4LO.
When driving on rough roads,
Set the 4WD shift switch to AUTO, 4H or
4LO.
Drive carefully according to the road surface
conditions.
When the vehicle is stuck,
Place stones or wooden blocks under the
tires to free the vehicle.
Set the 4WD shift switch to 4H or 4LO.
If it is difficult to free the vehicle, repeatforward and backward movement to increase
the movement.
If the vehicle is stuck deep in mud, tire chains
may be effective.
CAUTION
Do not increase the tire rotation ex-
cessively. Tires will sink deep into the
mud, making it difficult to free the
vehicle.
Avoid shifting gears with the engine
running at high speeds as this may
cause malfunction.4WD shift switch operationsShift the 4WD shift switch to either the 2WD,
AUTO, 4H or 4LO position, depending on
driving conditions.With the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending on
road conditions encountered [ratio;0:100
(2WD)→50 : 50 (4WD)]. This results in
improved driving stability.
If the 4WD shift switch is operated while
making a turn, accelerating or deceler-
ating or if the key switch is turned off
while in the AUTO, 4H or 4LO, you may
feel a jerk. This is not abnormal.
When the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt after
the selector lever is shifted to Nor P.

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

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.

WARNING
Do not stop or park the vehicle over
flammable materials, such as dry
grass, waste paper, or rags. They may
ignite and cause a fire.
The transfer shift lever must
be in the 2H, 4H or 4L position and
the parking brake must be set to
prevent the vehicle from rolling.
Never place the transfer shift lever inthe Nposition, otherwise, the vehicle
could roll unexpectedly even if the
manual transmission is in gear or the
automatic transmission is in the P
position. This could result in serious
personal injury or property damage.
Never leave the engine running while
the vehicle is unattended.
Never leave children unattended in
the vehicle.1. Firmly apply the parking brake.
2.Manual transmission models:
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the gearshift lever in the 1st position.
Automatic transmission models:
Move the selector lever to the P (Park) posi-
tion.
WARNING
Safe parking procedures require that
both the parking brake be set and the
transmission placed into the P (Park)
for automatic transmission models
or in an appropriate gear for manual
transmission models. Failure to do
so could cause the vehicle to move
unexpectedly or roll away and result
in an accident.
Make sure the automatic transmis-
sion selector lever has been pushed
as far forward as it can go and cannot
be moved without depressing the
button at the end of the lever.

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
BRAKE SYSTEM5-34

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.

FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.ANTI-FREEZEIn the winter when it is anticipated that the
temperature will drop below 32°F (0°C), check
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“8. Maintenance and do-it-yourself” section.BATTERYIf the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain
maximum efficiency, the battery should be
checked regularly. For details, see “Battery” in
the “8. Maintenance and do-it-yourself” section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without anti-
freeze, drain the cooling system by opening the
drain valves located under the radiator and on
the engine block. Refill before operating the
vehicle. See “Engine cooling system” in the “8.
Maintenance and do-it-yourself” section for
Changing Engine Coolant.
TIRE EQUIPMENT1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your vehicle
on snowy or icy roads, NISSAN recommends
the use of MUD & SNOW or ALL SEASON
tires on all four wheels. Please consult your
NISSAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, studded
tires may be used. However, some Provinces
and States prohibit their use, so, before
installing studded tires, check local, state and
provincial laws.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow
tires.
3. TIRE CHAINS may be used if desired. Make
sure they are of proper size for the tires on
your vehicle and are installed according to
the chain manufacturer’s suggestions. Use of
tire chains may be prohibited according to
location. Check the local laws before install-
ing tire chains. When installing tire chains,
make sure they are of proper size for the tires
on your vehicle and are installed according to

reaching it. Try not to brake while
actually on the ice, and avoid any
sudden steering maneuvers.
Do not use cruise control on slippery
roads.
Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)An engine block heater to assist extreme cold
temperature starting is available through your
NISSAN dealer.
WARNING
Do not use your heater with an un-
grounded electrical system or two-
pronged (cheater) adapters. You can be
injured by an electrical shock if you use
an ungrounded connection.
