WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation 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 with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle 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 rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer's rec-
ommendation to prevent carbon
monoxide entry into the vehicle. •
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.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
NOTE:
If the vehicle engine experiences exces-
sive fuel consumption or produces ex-
cessive smoke it is recommended that
you visit a NISSAN dealer for service.
THREE-WAY CATALYST (if so
equipped)
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

Please observe the following precautions:
WARNING
• Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.
• Do not drive across steep slopes. In-
stead 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 shif t gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
• 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 and apply brakes to control your
speed.
• 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.
• 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 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.
• Lower your speed when encounter-
ing 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 perfor-
mance capability of the tires, even
with 4WD engaged.
• For 4WD equipped vehicles, do not
attempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or per-
sonal injury.
