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.
For additional information regarding the above
warning, see “Warning/indicator lights and au-

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

Make sure the area around the vehicle is
clear.
Check fluid levels such as engine oil, coolant,
brake and clutch fluid, window washer fluid
as frequently as possible, at least whenever
you refuel.
Check to be sure that all windows and light
lenses are clean.
Visually inspect tires for their appearance and
condition. Also check tires for proper infla-
tion.
Lock all doors.
Position seat and adjust head restraints.
Adjust inside and outside mirrors.
Fasten seat belts and ask all passengers to
do likewise.
Check the operation of warning lights when
key is turned to the ON (3) position.1. Apply the parking brake.
2.Automatic transmission:
Move the selector lever to P (Park position) or
N (Neutral position). (P preferred)
The selector lever cannot be moved out
of P and into any of the other gear
positions if the ignition key is turned to
LOCK or if the key is removed from the
switch.
The starter is designed not to operate if
the selector lever is in one of the driving
positions.
Manual transmission:
Move the gearshift lever to N (Neutral posi-
tion), and depress the clutch pedal to the
floor while starting the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Crank the enginewith your foot off the
accelerator pedalby turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but fails to
run, repeat the above procedure.
If the engine is very hard to start in extremely
cold weather or when restarting, depress theaccelerator pedal a little (approximately 1/5
to the floor) and hold it then crank the engine.
Release the key and the accelerator pedal
when the engine starts.
If the engine is very hard to start because it is
flooded, depress the accelerator pedal all the
way to the floor and hold it. Crank the engine
for 5 to 6 seconds. After cranking the engine,
release the accelerator pedal. Crank the en-
ginewith your foot off the accelerator
pedalby turning the ignition key to START.
Release the key when the engine starts. If the
engine starts, but fails to run, repeat the
above procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, turn the key off and wait 10
seconds before cranking again, other-
wise the starter could be damaged.
4.Warm-up
Always allow the engine to idle for at least 30
seconds after starting. Drive at moderate
speed for a short distance first, especially in
cold weather.

Shift lock releaseIf the battery charge is low, the select lever may
not be moved from the P position even with the
brake pedal depressed and the select lever
button pushed.
To move the select lever, remove the shift lock
cover using a flat-bladed screwdriver, and push
the shift lock release button and select lever
button with the parking brake securely applied
and the brake pedal firmly depressed. The select
lever can be moved to N (Neutral).
To push the shift lock release button, follow the
procedure as illustrated.
If the lever cannot be moved out of P (Park) have
your NISSAN dealer check the automatic trans-
mission system as soon as possible.
WARNING
If the selector lever cannot be moved
from the P position while the engine is
running and the brake pedal is de-
pressed, the stop lights may not work.
Malfunctioning stop lights could cause
an accident injuring yourself and others.
Accelerator downshift
— In D position —For rapid passing or hill climbing, fully depress
the accelerator pedal to the floor. This shifts the
transmission down into second gear or first gear,
depending on the vehicle speed.
Overdrive switchEach time your vehicle is started, the transmis-
sion is automatically reset to overdrive on.
ON: For normal driving the overdrive switch
is engaged. The transmission is up-
shifted into overdrive as the vehicle
speed increases.
The overdrive does not engage until the
engine has warmed up.
OFF: For driving up and down long slopes
where engine braking would be advan-
tageous, push the overdrive switch. The
O/D OFF light illuminates. When cruis-

ing at a low speed or climbing a gentle
slope, you may feel uncomfortable shift
shocks as the transmission shifts be-
tween 3rd and overdrive repeatedly. In
this case, press the overdrive switch.
The O/D OFF indicator light comes on
at this time.
When driving conditions change, press the over-
drive switch again. The O/D OFF indicator light
goes out.
Remember not to drive at high speeds for ex-
tended periods of time with the O/D OFF light
illuminated. This reduces the fuel economy.
Fail-safeWhen the Fail-safe operation occurs, the next
time the key is turned to the ON position, the
O/D OFF light will blink for approximately 8
seconds after coming on for 2 seconds. While
the vehicle can be driven under these circum-
stances please note that the gears in the auto-
matic transmission may be locked in third gear.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the Fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition key
OFF and wait for 3 seconds. Then turn thekey back to the ONposition. The vehicle
should return to its normal operating con-
dition. If it does not return to its normal
operating condition have your NISSAN
dealer check the transmission and repair if
necessary.

Doing so could cause a loss of vehicle
control and result in an accident.
CAUTION
On manual transmission models, do not
shift into N(Neutral) without depressing
the clutch pedal when the cruise control
is set. Should this occur, depress the
clutch pedal and turn the main switchoff immediately. Failure to do so may
cause engine damage.
PRECAUTIONS ON CRUISE
CONTROLIf the engine coolant temperature becomes
excessively high, the cruise control system
will automatically be canceled.
If the cruise control system malfunctions, it
cancels automatically. The SET indicator light
in the instrument panel then blinks to warn
the driver.
If the SET indicator light blinks, turn the
cruise control main switch off and have the
system checked by your NISSAN dealer.
The SET indicator light may blink when the
cruise control main switch is turned on while
pushing the RES/ACCEL, COAST/
SET, or CANCEL switch (located on the
steering wheel). To properly set the cruise
control system, perform the preceding steps
in the order indicated.
CRUISE CONTROL OPERATIONSThe cruise control allows driving at a fixed speed
between 25 to 89 MPH (40 to 144 km/h)

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.

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.

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
