FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or ser-
iously injured if it is misused or
mishandled. Always stop engine and
do not smoke or allow open flames or
sparks near the vehicle when refuel-
ing.
. Do not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, resulting
in fuel spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious malfunction and possible injury. It
could also cause the malfunction
indicator light to come on.
. Never pour fuel into the throttle body
to attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
— Always place the container on the ground when filling.
— Do not use electronic devices when filling.
— Keep the pump nozzle in contact with the container while you are
filling it.
— Use only approved portable fuel containers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage. .
Insert the cap straight into the fuel-
filler tube, then tighten until the fuel-
filler cap clicks. Failure to tighten the
fuel-filler cap properly may cause the
malfunction indicator light (MIL)
to illuminate. If thelight illumi-
nates because the fuel-filler cap is
loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn off after a
few driving trips. If thelight does
not turn off after a few driving trips,
have the vehicle inspected. It is
recommended you visit an INFINITI
retailer for this service.
. The Loose Fuel Cap warning will
appear if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the message to be
displayed. Failure to tighten the fuel-
filler cap properly after the Loose
Fuel Cap warning appears may cause
the
Malfunction Indicator Light
(MIL) to illuminate.
Turn the cap counterclockwise to remove.
To tighten, turn the cap clockwise until a
single click is heard.

AROUND VIEW®MONITOR SYS-
TEM LIMITATIONS
WARNING
Listed below are the system limitations
for Around View®Monitor. Failure to
operate the vehicle in accordance with
these system limitations could result in
serious injury or death.
. Do not use the Around View
®Moni-
tor with the outside mirrors in the
stored position, and make sure that
the liftgate is securely closed when
operating the vehicle using the
Around View
®Monitor.
. The apparent distance between ob-
jects viewed on the Around View
®

5-4Starting and driving
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
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
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. 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 liftgate closed while driving,
otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the
liftgate open, follow these precau-
tions:
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
connections must pass to a trailer
through the seal on the liftgate or the
body, follow the manufacturer’s re-
commendation to prevent carbon
monoxide entry into the vehicle.
. The exhaust system and body should
be inspected by a qualified mechanic
whenever:
— The vehicle is raised for service. — You suspect that exhaust fumes
are entering into the passenger
compartment.
— You notice a change in the sound of the exhaust system.
— You have had an accident invol- ving damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
THREE-WAY CATALYST
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.
WARNING
. The exhaust gas and the exhaust
system are very hot. Keep people,
animals 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.
PRECAUTIONS WHEN STARTING
AND DRIVING

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. Properly secure all cargo so
it will not be thrown forward and
cause injury to you or your passen-
gers.
. 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. 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 became hot. .
Lower your speed when encountering
strong crosswinds. With a higher
center of gravity, your INFINITI is
more affected by strong side winds.
Slower speeds ensure better vehicle
control.
. Do not drive beyond the performance
capability of the tires, even with
4WD engaged.
. For 4WD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift 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 personal
injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing), or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could result in serious vehicle damage or
personal injury (4WD models).
. When a wheel is off the ground due
to an unlevel surface, do not spin the
wheel excessively.
. 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 vehicle has a higher
center of gravity than a conventional
passenger car. The vehicle is not
designed for cornering at the same
speeds as conventional passenger
cars. Failure to operate this vehicle
correctly could result in loss of con-
trol and/or a rollover accident.
. 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 rear wheels when driving on
slippery roads and drive carefully.
. Be sure to check the brakes immedi-
ately after driving in mud or water.
See “Brake system” (P.5-122) for
wet brakes.
. Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
Starting and driving5-11

5-12Starting and driving
it rolls forward, backward or side-
ways, you could be injured.
. Whenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent
maintenance may be required. See
the maintenance schedules shown in
the "9. Maintenance and schedules"
section.
. Spinning the rear wheels on slippery
surfaces may cause the 4WD warn-
ing light to flash. The 4WD system
may also automatically switch from
the 4WD mode to the 2WD mode.
This could reduce traction. Be espe-
cially careful when towing a trailer
(4WD models).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 3
consecutive times 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.
Before operating the push-button ignition
switch, be sure to move the shift lever to the
P (Park) position.
