strip during power close, the liftgate will re-
verse direction and return to the full open
position.
NOTE:
If the pinch strip is damaged or removed, the
power close function will not operate.
WARNING
There are some small distances immedi-
ately before the closed position which can-
not be detected. Make sure that all passen-
gers have their hands, etc., inside the
vehicle before closing the liftgate.Manual Mode:
If power operation is not available, the lift-
gate may be operated manually. Power op-
eration may not be available if multiple ob-
stacles have been detected in a single power

WARNING
∙ Do not leave children or adults whowould normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acciden-
tally 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 with ropes or straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, 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 en- tering 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 rear vent windows, liftgates, doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
∙ If electrical wiring or other cable connec- tions must pass to a trailer through the
seal on the liftgate or the body, follow
the manufacturer’s recommendation 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 involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
∙ The exhaust gas and the exhaust systemare very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
∙ Do not stop or park the vehicle over flam- mable materials such as dry grass, waste
paper or rags. They may ignite and cause
a fire.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-4Starting and driving

INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently and most people underestimate the
effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). 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 2-Wheel Drive (2WD) mod-
els are less capable than All-Wheel Drive
(AWD) models for rough road driving and
extrication when stuck in deep snow or mud,
or the like.Please observe the following precautions:
WARNING
∙ Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD to
the 2WD mode. This could reduce the
traction. Be especially careful when tow-
ing a trailer (AWD models).
∙ 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 gears while driving on down-
hill grades as this could cause loss of con-
trol 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 con-
trol your speed.
∙ Heavy braking going down a hill could cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear 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.
∙ 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.

INTELLIGENT ALL-WHEEL
DRIVE (AWD) DRIVING SAFETY
PRECAUTIONS (if so equipped)
WARNING
∙ Replacing tires with those not originallyspecified by INFINITI could affect the
proper operation of the TPMS.
∙ Always use tires of the same type, size, brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
∙ This vehicle is not designed for off-road (rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the ground
and shift the transmission to any D
(Drive) or R (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 personal injury. ∙ Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
∙ When a wheel is off the ground due to an unlevel surface, do not spin the wheel
excessively.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (The engine will stop when the
ignition switch is pushed three consecutive
times in quick succession or the ignition
switch is pushed and held for more than
2 seconds.) If the engine stops while the
vehicle is being driven, this could lead to a
crash and serious injury.
