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 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 to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. 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 engine
running for any extended length of time.
. Keep the lift gate closed while driving,
otherwise exhaust gases could be drawn
into the passenger compartment. If you
must drive with the lift gate open, follow
these precautions:
1) Open all the windows.
2) Set the
air recirculation to off
and the fan control to high to
circulate the air.
. If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the lift gate or the body,
follow the manufacturer’s recommenda-
tion to prevent carbon monoxide entry
into the vehicle.
. The exhaust system and body should be
inspected by a qualified mechanic when-
ever:
—The vehicle is raised for service.
—You suspect that exhaust fumes are
entering into the passenger compart-
ment.
—You notice a change in the sound ofthe exhaust system.
—You have had an accident involvingdamage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission
control device installed in the exhaust
system. Exhaust gases in the three-way
catalyst are burned at high temperatures to
help reduce pollutants.
WARNING
. The exhaust gas and the exhaust system
are very hot. Keep people, animals or
flammable materials away from the
exhaust system components.
. Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and

PRECAUTIONS WHEN STARTING AND
DRIVING

Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is
mainly designed for leisure use, unlike a
conventional off-road vehicle.
Remember that Two-Wheel Drive (2WD)
models are less capable than All-Wheel
Drive (AWD) models for rough road driving
and extrication when stuck in deep snow,
mud, or the like.
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. 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 vehicle.
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 ranges 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) range. Never back down in N
(Neutral), 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 range to control your speed. .
Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly 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 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. Instead 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 became hot.
. Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your INFINITI is more affected
