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 operations
Shift 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.

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
so the wheels will not lock when braking abruptly
or when braking on slippery surfaces. The sys-
tem detects the rotation speed at each wheel
and varies the brake fluid pressure to prevent
each wheel from locking and sliding. By prevent-
ing wheel lockup, the system helps the drivermaintain steering control and helps to minimize
swerving and spinning on slippery surfaces.
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 and Loading
Information label. See “Vehicle iden-
tification” in the “9. Technical and
consumer information” section for
Vehicle identification location infor-
mation.

on.

The vehicle dynamic control system
is not a substitute for winter tires or
tire chains on a snow covered road.
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.

damage.
4. Turn off the engine.
5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you need help.
6. Have all passengers get out of the vehicle
and stand in a safe place away from traffic
and clear of the vehicle.
WARNING

Make sure that the parking brake is
securely applied and the manual
transmission is shifted into R (re-
verse), on the automatic transmis-
sion in P (Park).

Never change tires when the vehicle
is on a slope, ice or a slippery area.
This is hazardous.

Never change tires if oncoming trafficis close to your vehicle. Wait for pro-
fessional road assistance.

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. (For models
with the low tire pressure warning
system)
Blocking wheelsPlace suitable blocks at both the front and back
of the wheel diagonally opposite the flat tire to
prevent the vehicle from rolling when it is jacked
up.
WARNING
Be sure to block the wheel as the ve-
hicle may move and could cause per-
sonal injury.

supported only by the jack.

Use only the jack provided with your
vehicle to lift the vehicle. Do not use
the jack provided with your vehicle
on other vehicles. The jack is de-
signed only for lifting your vehicleduring a tire change.

Use the correct jack up points; never
use any other part of the vehicle for
jack support.

Never jack up the vehicle more than
necessary.

Never use blocks on or under the
jack.

Do not start or run engine while ve-
hicle is on the jack, as it may causethe vehicle to move. This is especially
true for vehicle with limited slip dif-
ferentials.

Do not allow passengers to stay in
the vehicle while it is on the jack.
Carefully read the following instructions.
1. Place the jack directly under the jack-up
point.
The jack should be used on level firm
ground.
2. Loosen each wheel nut one or two turns by
turning counterclockwise with the wheel nut
wrench.
Do not remove the wheel nuts until the tire
is off the ground.
3. Carefully raise the vehicle until the tire clears
the ground. To lift the vehicle, securely hold
the jack lever and rod with both hands as
shown above. Remove the wheel nuts, and
then remove the wheel. Do not remove the
brake drum with the wheel.

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.
Part time four wheel drive modelsNISSAN recommends that towing dollies be
used when towing your vehicle or the vehicle be
placed on a flat bed truck as illustrated.
