FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop engine and do not smoke or
allow open flames or sparks near the
vehicle when refueling.
. Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling 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 emis-
sion control system. An incorrect cap can result in a serious malfunction and
possible injury. It could also cause the
Malfunction Indicator Light (MIL) 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 whenfilling.
—Keep the pump nozzle in contact
with the container while you are
filling it.
—Use only approved portable fuelcontainers 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 the fuel-filler cap until
a single click is heard. Failure to tighten
the fuel-filler cap properly may cause the
Malfunction Indicator Light (MIL) to
illuminate. If thelight illuminates
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 by an INFINITI retailer.
. 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 warning to be displayed.
Failure to tighten the fuel-filler cap
properly after the Loose Fuel Cap warn-
ing appears may cause the
Mal-
function Indicator Light (MIL) to
illuminate.

3. Push theorswitch*Aon the
steering wheel for longer than 1 second
to turn off the Loose Fuel Cap warning
after tightening the fuel-filler cap.WARNING
. Do not adjust the steering wheel while
driving. You could lose control of your
vehicle and cause an accident.
. Do not adjust the steering wheel any
closer to you than is necessary for
proper steering operation and comfort.
The driver’s air bag inflates with great
force. If you are unrestrained, leaning
forward, sitting sideways or out of
position in any way, you are at greater
risk of injury or death in a crash. You
may also receive serious or fatal injuries
from the air bag if you are up against it
when it inflates. Always sit back against
the seatback and as far away as practical
from the steering wheel. Always use the
seat belts.

TILT/TELESCOPIC STEERING

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.
. Closely supervise children when they are
around cars to prevent them from play-
ing and becoming locked in the trunk
where they could be seriously injured.
Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.
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 trunk lid closed while driving,
otherwise exhaust gases could be drawn
into the passenger compartment. If you
must drive with the trunk lid 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 trunk lid 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 of
the exhaust system.
—You have had an accident involvingdamage to the exhaust system,
underbody, or rear of the vehicle.

PRECAUTIONS WHEN STARTING AND
DRIVING

5-10Starting and driving
Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
INTELLIGENT ALL-WHEEL DRIVE
(AWD) DRIVING SAFETY PRECAU-
TIONS (AWD models)
WARNING
.Do not drive beyond the performance
capability of the tires, even with Intelli-
gent AWD engaged. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control.
. 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.
. 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
attempt 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 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.
