This occurs because the transfer clutch
is released and not because of a mal-
function.
CAUTION
IWhen 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.
IDo not shift the 4WD shift switch
while driving on steep downhill
grades. Use the engine brake.
IDo not operate the 4WD shift switch
with the rear wheels spinning.
IBefore 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 system.
INever shift the 4WD shift switch be-
tween 4LO and 4H while driving.
IEngine idling speed is high while
warming up the engine. Be espe-cially 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.
IThe 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

this occurs, move the 4WD shift switch to the
4H or 4LO position.
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
second). If the warning light blinks rapidly
during operation, stop the vehicle in a safe
place immediately. 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 sec-
onds). Change the 4WD shift switch into 2WD
and do not drive fast.
CAUTION
IIf 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.
IShifting between 4H and 4LO is not
recommended when the 4WD warn-
ing light turns on.
IWhen 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.
IDo 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
Iin the AUTO or 4H position, shift
the 4WD shift switch to 2WD.
Iin the 4LO position, stop the ve-hicle, move the automatic transmis-
sion lever to the N position, and shift
the 4WD shift switch to 2WD.
IIf the warning light is still on after the
above operation, have your vehicle
checked by an authorized NISSAN
dealer as soon as possible.
IThe transfer case may be damaged if
you continue driving with the warning
light blinking rapidly.

WARNING
IDo not stop or park the vehicle over
flammable materials, such as dry
grass, waste paper, or rags. They may
ignite and cause a fire.
I
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.
INever place the transfer shift lever inthe N position, 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.
INever leave the engine running while
the vehicle is unattended.
INever leave children unattended in
the vehicle.1. Firmly apply the parking brake.
2.Manual transmission models:
Place the shift lever in the R (Reverse)
position. 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)
position.
WARNING
ISafe 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 un-
expectedly or roll away and result in
an accident.
IMake 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:
IIf 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:
IIf 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 stop-
ping the engine. Otherwise, the ve-
hicle 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,it is a good practice to turn the wheels as
illustrated.
IHEADED DOWNHILL WITH CURB:
q1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
IHEADED UPHILL WITH CURB:
q2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
IHEADED UPHILL OR DOWNHILL, NO
CURB:
q3
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, espe-
cially 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 en-
gine 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
IWhile driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
IIf 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 helps the driver maintain steering con-trol and helps to minimize swerving and spin-
ning 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
BRAKE SYSTEM5-32

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 elec-
tronic sensors, electric pumps, and hydraulic
solenoids controlled by a computer. The com-
puter 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 malfunction, it switches the anti-
lock brake system OFF and turns on the ABS
brake warning light in the dashboard. The
brake system will then behave 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.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen installing a spare tire, make
sure it is the proper size and type asspecified on the tire placard. See
ªTire placardº in the ª10. Technical
and consumer informationº section
for tire placard location information.

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 32ÉF (0ÉC), check
anti-freeze (ethylene glycol base) to assure
proper winter protection. For details, see ªEn-
gine cooling systemº in the ª8. Do-it-yourselfº
section.BATTERYIf the battery is not fully charged during ex-
tremely 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
ªBatteryº in the ª8. Do-it-yourselfº section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain valves located under the radiator
and on the engine block. Refill before operat-
ing the vehicle. See ªEngine cooling systemº in
the ª8. Do-it-yourselfº 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 Prov-
inces 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 ac-
cording to the chain manufacturer's sug-
gestions. Use of tire chains may be prohib-
ited according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are of
proper size for the tires on your vehicle andare installed according to the chain manu-
facturer's suggestions.Use only SAE
Class S chains.Other types may damage
your vehicle. Use chain tensioners when
recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of
the tire chain must be secured or removed
to prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected.
Do not use the chains on dry roads.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains
in such conditions can cause damage to the
various mechanisms of the vehicle due to
some overstress. When driving on clear
paved roads, be sure to change to 2WD.
4. For four wheel drive:
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.

CAUTION
ONLY use spare tires specified for each
four wheel drive model.SPECIAL WINTER EQUIPMENTIt is recommended that the following items be
carried in the vehicle during winter:
IA scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
IA sturdy, flat board to be placed under the
jack to give it firm support.
IA shovel to dig the vehicle out of snow-
drifts.
IExtra window washer fluid to refill the res-
ervoir tank.DRIVING ON SNOW OR ICE
WARNING
IWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow or ice can be slick andvery hard to drive on. The vehicle will
have a lot less traction or grip under
these conditions. Try to avoid driving
on wet ice until the road is salted or
sanded.
IWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction.
IAllow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
IAllow greater following distances on
slippery roads.
IWatch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while
actually on the ice, and avoid any
sudden steering maneuvers.
IDo not use cruise control on slippery
roads.ISnow 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.
