Your NISSAN is designed for both normal
and off-road use. It has a higher ground
clearance and a narrower track to make it
suitable for off-road use. These characteris-
tics give the vehicle a higher center of
gravity than ordinary passenger cars. An
advantage of the higher ground clearance is
a better view of your surroundings, allowing
you to anticipate problems. However, avoid
driving in deep water or mud as your
NISSAN is mainly designed for leisure use,
unlike a conventional off-road vehicle.
Please observe the following precautions:
WARNING
IDrive carefully when off the road and
avoid dangerous areas. Always wear
your seat belts to help keep you and
your passengers in position when
driving over rough terrain.
IDo not drive across steep slopes.
Instead drive either straight up or
straight down the slopes. Off-road
vehicles can tip over sideways much
more easily than they can forward or
backward.IMany hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you
may not be able to control your
speed. If you drive across them, you
may roll over.
IStay alert when driving to the top of
a hill. At the top there could be a
drop-off or other hazard that could
cause an accident.
IIf your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in reverse gear.
Never back down in N (neutral) or
with the clutch depressed, using
only the brake, as this could cause
loss of control.
I
Heavy braking going down a hill could
cause your brakes to overheat and
fade, resulting in loss of control and
an accident. Apply brakes lightly and
use a low gear to control your speed.
IIf at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN four-wheel drive
vehicle has a higher center of gravitythan a two-wheel drive vehicle and can
tip over more easily. The vehicle is not
designed for cornering at the same
speeds as conventional two-wheel
drive vehicles any more than low-
slung sports cars are designed to per-
form satisfactorily under off-road con-
ditions. Failure to operate this vehicle
correctly could result in loss of con-
trol and/or a rollover accident.
IUnsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure it so that it will
not be thrown forward and cause
injury to you or your passengers.
IAvoid raising the center of gravity by
loading things on the roof or equip-
ping the vehicle with tires larger than
specified in this manual. This could
cause your vehicle to roll over. Put
heavy loads in the cargo area as far
forward and as low as possible.
IDo not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could jerk
and injure your hands. Instead drive
with your fingers and thumbs on the
outside of the rim.
DRIVING YOUR
FOUR-WHEEL DRIVE SAFELY
5-24Starting and driving
ZX

IBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
IAlways drive with the floor mats in
place as the floor may become very
hot. Particular care should be taken
if you are barefoot.
ILower your speed when encounter-
ing strong crosswinds. With its
higher center of gravity, your
NISSAN is more affected by gusty
side winds. Slower speeds ensure
better vehicle control.
IDo not drive beyond the perfor-
mance of the tires even with 4WD.
IAccelerating quickly, steering or
braking may cause loss of control.
IInstall the same size of winter tires
on all four (four) wheels (such as
studless tires) or install tire chains
to the rear wheels when driving on
slippery roads (e.g., after a snow)
and drive carefully using 4WD.
IBe sure to check the brakes immedi-
ately after driving in mud or water asspecified in ``Wet brakes'' under the
heading ``Brake system,'' later in this
section.
IAvoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
IWhenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent
maintenance may be required. For
details, refer to ``Maintenance for off-
road driving'' in the ``Maintenance''
section of this manual.
Checking water entry
If you have driven in deep water or mud,
check water entry in the clutch housing by
removing the blind plug at the bottom of the
transmission case. After checking, be sure
to reinstall the plug.

CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. A spare tire of the same size,
brand, construction and tread pattern
must also be used. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axles
which will cause excessive tire wear
and may damage the transmission,
transfer case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. Contact an
authorized NISSAN dealer.
Snow tires
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
Tire inflation pressure
Periodically check the pressure in all tires,
including the spare, with a gauge. Adjust to
the specified pressure if necessary. Tire
pressures are shown on the tire placard
affixed to the glove box.
Tire chain
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.

WARNING
IDo not park the vehicle over flam-
mable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
I
The transfer control lever
must be in the 2H, 4H or 4L position
and the parking brake set to prevent
the vehicle from rolling.
INever place the transfer control le-
ver in the N (Neutral) position. Oth-
erwise, the vehicle could roll unex-pectedly even if the manual trans-
mission is in gear or the automatic
transmission is in the P (Park) posi-
tion. This could result in serious per-
sonal injury or property damage.
ISafe parking procedures require that
both the parking brake be set and
the transmission placed into P (Park)
position (automatic) or in the appro-
priate gear (manual). Failure to do so
could cause the vehicle to move un-
expectedly or roll away and result in
an accident. Make sure the gearlever has been pushed as far forward
as it can go and cannot be moved
without depressing the button at the
end of the lever.
INever leave children unattended in
the vehicle.
I
Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls.
Unattended children could become
involved in serious accidents.
IIf the ATP lamp 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 4LO could
result in the vehicle moving unex-
pectedly, resulting in serious per-
sonal injury or property damage.
1. Firmly apply the parking brake.
2.Manual transmission models:
Place the gearshift lever in the R (Re-
verse) position. When parking on an up-MSD0002

hill grade, place the gearshift lever in the
1st position.
Automatic transmission models:
Move the gearshift lever to the P (Park)
position.
3. To help prevent the vehicle from rolling
into the street when parked on an incline,
it is a good practice to turn the wheels as
illustrated.
IHEADED DOWNHILL WITH CURB:À
1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
IHEADED UPHILL WITH CURB:Á
2
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:Â
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.
4. Turn the ignition key to the LOCK posi-
tion 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. How-
ever, much greater steering effort is needed,
especially in sharp turns and 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.The brake system has two separate hydrau-
lic circuits. If one circuit develops a problem,
you will still have braking at two wheels.
Vacuum assisted brakes
The 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 stopping distance will be longer.
Wet brakes
When 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 the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function cor-
rectly.
