WARNING

Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.

Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.EXHAUST GAS (Carbon monoxide)
WARNING
Do not breathe exhaust gases; they con-tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous.
It can cause unconsciousness or death.

If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.

Do not run the engine in closed
spaces such as a garage.

Do not park the vehicle with the en-
gine running for any extended length
of time.

Keep the back door closed while driv-
ing, otherwise exhaust gases could
be drawn into the passenger com-
partment. If you must drive with the
back door open, follow these precau-
tions:
1. Open all the windows.
2. Set the air recirculation button off
and the fan control at the highest
position to circulate the air.

If electrical wiring or other cable con-nections must pass to a trailer
through the seal on the back door or
the body, follow the manufacturer’s
recommendation to prevent carbon
monoxide entry into the vehicle.

If a special body or other equipment
is added for recreational or other
usage, follow the manufacturer’s rec-
ommendation to prevent carbon
monoxide entry into the vehicle.
(Some recreational vehicle appli-
ances such as stoves, refrigerator,
heaters, etc. may also generate car-
bon monoxide.)

The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound
of the exhaust system.PRECAUTIONS WHEN STARTING

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. Exhaust
gases in the converter are burned at high tem-
peratures 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 dry
grass, 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 a 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.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle.As
with any vehicle, a loss of control could
result in a collision with other vehicles or
objects, or cause the vehicle to rollover,
particularly if the loss of control causes the
vehicle to slide sideways.Be attentive at all
times, and avoid driving when tired. Never drive
when under the influence of alcohol or drugs
(including prescription or over-the-counter
drugs which may cause drowsiness). Always
wear your seat belt. See “Seat belts” in the “1.
Safety — Seats, seat belts and supplemental
restraint system” section. Also instruct your pas-
sengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.In a rollover crash, an

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 a
hill. 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 thebrake, 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 range 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 (if so
equipped) 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 ve-
hicle to roll over.

Do not grip the inside or spokes of
the steering wheel when driving off-road. 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.
Slower speeds ensure better vehicle
control.

Do not drive beyond the performance
of the tires, even with 4WD engaged.
Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.

If at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN four wheel
drive vehicle has a higher center of

NISSAN VEHICLE IMMOBILIZER
SYSTEMThe Nissan Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
If the engine does not start using a registered
key (for example, when interference is caused by
another registered key, an automated toll road
device or automated payment device on the key
ring), restart the engine using the following
procedures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.2. Turn the ignition switch to the OFF or LOCK
position and wait approximately 10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered key.
If this procedure allows the engine to start,
NISSAN recommends placing the registered key
on a separate key ring to avoid interference from
other devices.

matic transmission as soon as possible.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 lower range, depending
on the vehicle speed.
Overdrive switchEach time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and the shift
selector lever in the D (Drive) position, the
transmission upshifts into Overdrive as ve-
hicle speed increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down long slopes
where engine braking is necessary push
the Overdrive switch once. The O/D OFF
indicator light in the instrument panelcomes on at this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts into and out of
Overdrive repeatedly. In this case, depress the
Overdrive switch to turn the Overdrive off. The
O/D OFF indicator light in the instrument panel
comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
Remember not to drive at high speeds for ex-
tended periods of time with the Overdrive off.
This reduces fuel economy.
Fail-safeIf 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 the
key back to the ONposition. The vehicle
may return to its normal operating condi-
tion. If it does not return to its normal
operating condition have a NISSAN dealer
check the transmission and repair if neces-
sary.

WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually re-
duced. On highways, the reduced speed
may be lower than other traffic which
could increase the chance of a collision.
Be especially careful when driving. If
necessary, pull to the side of the road at
a safe place and allow the transmission
to return to normal operation, or have it
repaired if necessary.
