Operating tips
Keep windows and sun roof closed while theair conditioner is in operation.

After parking in the sun, drive for two or three
minutes with the windows open to vent hot air
from the passenger compartment. Then,
close the windows. This will allow the air
conditioner to cool the interior more quickly.

The air conditioning system should be
operated for about ten minutes at least
once a month. This helps prevent dam-
age to the system due to lack of lubri-
cation.

If the coolant temperature gauge exceeds the
hot position, turn the air conditioner off. For
additional information, see “If your vehicle
overheats” in the “6. In case of emergency”
section.

b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound
of the exhaust system.
d. You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE WAY CATALYSTThe three way catalyst is an emission control
device, installed in the exhaust system. In the
converter, exhaust gases are burned at high
temperatures to help reduce pollutants.
WARNING

The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system compo-
nents.

Do not stop or park the vehicle over
flammable materials, such as drygrass, waste paper or rags. They may
ignite and cause a fire.
CAUTION

Do not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst’s ability
to help reduce exhaust pollutants.

Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by an authorized
NISSAN dealer.

Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.
Do not race the engine while warm-
ing it up.

Do not push or tow your vehicle to
start the engine.
LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)The low tire pressure warning system monitors
tire pressure of all wheels (except the spare tire).
The low tire pressure warning system will acti-
vate only when the vehicle is driven at speeds
above 20 MPH (32 km/h). Also, this system may
not detect a sudden drop in tire pressure (for
example a flat tire by catching something while
driving).
Frequently check the tire pressure and adjust
pressure of each tire properly.LOW PRESSURE warningIf the vehicle is being driven with a flat tire or low
tire pressure (lower than 25 psi, 171 kPa), the
low tire pressure warning light illuminates and
the chime sounds for about 10 seconds.

Before driving up or down grades,
check the road surface for bumps or
potholes. Be sure to climb a gentle
slope and descend a gentle slope.

Do 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.

Many 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.

Do not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.

Be sure to use the engine brake. The
foot brake performance may be re-
duced, resulting in a possible acci-
dent.

Stay alert when driving to the top of ahill. At the top there could be a drop-
off or other hazard that could cause
an accident.

If 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 R (Reverse)
gear. Never back down in N (Neutral)
or with the clutch depressed (manual
transmission vehicles), using only the
brake, as this could cause loss of
control.

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.

Unsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.
To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack and evenly
distribute the load. Secure heavy
loads in the cargo area as far forward
and as low as possible. Do not equip
the vehicle with tires larger than
specified in this manual. This could
cause your vehicle to roll over.

Do not grip the inside or spokes of
the steering wheel when driving of-
froad. The steering wheel could move
suddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim.

Before operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.

Always drive with the floor mats in
place as the floor may become hot.

Lower your speed when encountering
strong crosswinds. With a higher
center of gravity, your NISSAN is
more affected by strong side winds.5-6

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

CAUTION
Do not keep starter motor engaged for
more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before trying
again.
7. After starting your engine, carefully discon-
nect the negative cable and then the positive
cable.
8. Replace the vent caps (if so equipped). Be
sure to dispose of the cloth used to cover the
vent holes as it may be contaminated with
corrosive acid.
CAUTION

Automatic transmission models can-
not be push started. This may cause
transmission damage.

Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.

Never try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.If your vehicle is overheating indicated by an
extremely high temperature gauge reading, or if
you feel a lack of engine power, detect abnormal
noise, etc., take the following steps:
WARNING

Do not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.

To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the ra-
diator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.

Do not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, apply the
parking brake and move the gearshift lever to
the neutral position (automatic transmission

3. If engine overheating is caused by climbing a
long hill on a hot day, run the engine at a fast
idle (approximately 1,500 rpm) until the tem-
perature gauge indication returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no steam
or coolant can be seen before proceeding.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the cooling fan belt is missing or loose or the
cooling fan does not run, stop the engine.
WARNING

Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in, the
cooling fan, or drive belt.

The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at the
nearest NISSAN dealer.When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must
be followed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from your NISSAN dealer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing. To
assure proper towing and to prevent accidental
damage to your vehicle, NISSAN recommends
having a service operator tow your vehicle. It is
advisable to have the service operator carefully
read the following precautions:
WARNING

Never ride in a vehicle that is being
towed.

Never get under your vehicle after it
has been lifted by a tow truck.
CAUTION

When towing, make sure that the
transmission, axles, steering system
and powertrain are in working condi-TOWING YOUR VEHICLE
