FUEL-FILLER CAP
WARNING
● Gasoline is extremely flammable and highly
explosive under certain conditions. 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 automati-
cally. Continued refueling may cause fuel
overflow, resulting in fuel spray and possi-
bly 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 sys-
tem. An incorrect 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 at-
tempt 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 contain- ers 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 the
light illuminates because the fuel-
filler cap is loose or missing, tighten or in-
stall the cap and continue to drive the ve-
hicle. 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 (if so equipped)
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 (if so equipped) ap-
pears may cause the
Malfunction Indi-
cator Light (MIL) to illuminate.
The fuel-filler cap is a ratcheting type. Turn the
cap counterclockwise to remove. To tighten,
turn the cap clockwise until ratcheting clicks
are heard.
3-24Pre-driving checks and adjustments

WARNING
●The Around View Monitor is a convenience
but it is not a substitute for proper vehicle
operation because it has areas where ob-
jects cannot be viewed. Always look out the
windows and check to be sure that it is safe
to move before operating the vehicle. Always
operate the vehicle slowly.
● Do not use the Around View Monitor with the
outside mirror in the stored position, and
make sure that the lift gate is securely
closed when operating the vehicle using the
Around View Monitor.
● The distance between objects viewed on the
Around View Monitor differs from the actual
distance.
● The cameras are installed above the front
grille, the outside mirrors and above the rear
license plate. Do not put anything on the
cameras.
● When washing the vehicle with high-
pressure water, be sure not to spray it
around the cameras. Otherwise, water may
enter the camera unit causing water conden-
sation on the lens, a malfunction, fire or an
electric shock. ●
Do not strike the cameras. They are precision
instruments. Doing so could cause a mal-
function or cause damage resulting in a fire
or an electric shock.
CAUTION
Do not scratch the lens when cleaning dirt or
snow from the front of the camera.
NOTE:
The color of the view on the Around View Monitor
display is different from the actual view because
the system uses infrared cameras.

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 them-
selves 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 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 dangerous. It can cause
unconsciousness or death.
● If you suspect that exhaust fumes are enter-
ing 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 run-
ning for any extended length of time.
● Keep the lift gate closed while driving, oth-
erwise 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 connec-
tions must pass to a trailer through the seal
on the lift gate or the body, follow the manu-
facturer’s recommendation to prevent car-
bon monoxide entry into the vehicle.
● The exhaust system and body should be in-
spected by a qualified mechanic whenever:
– The vehicle is raised for service.
– You suspect that exhaust fumes are en- tering into the passenger compartment.
– You notice a change in the sound of the exhaust system. – You have had an accident involving dam-
age 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 flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-2Starting and driving

●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. Properly se-
cure all cargo so it will not be thrown forward
and cause injury to you or your passengers.
● To avoid raising the center of gravity exces-
sively, do not exceed the rated capacity of
the roof rack (if so equipped) and evenly dis-
tribute the load. Secure heavy loads in the
cargo area as far forward and as low as pos-
sible. 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 steer-
ing wheel when driving off-road. The steer-
ing 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 by strong side
winds. Slower speeds ensure better vehicle
control.
● Do not drive beyond the performance capa-
bility 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 po-
sition with the engine running. Doing so may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury. ●
Do not attempt to test a 4WD equipped ve-
hicle 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 facil-
ity personnel that your vehicle is equipped
with 4WD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous 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 maneu-
vers or sudden braking may cause loss of
control.
● If at all possible, avoid sharp turning maneu-
vers, particularly at high speeds. Your ve-
hicle 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. Fail-
ure to operate this vehicle correctly could
result in loss of control and/or a rollover
accident.
Starting and driving5-9

●Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), 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 immediately af-
ter driving in mud or water. See “BRAKE SYS-
TEM” later in this section for wet brakes.
● Avoid parking your vehicle on steep hills. If
you get out of the vehicle and it rolls forward,
backward or sideways, 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 information in the “INFINITI
Service and Maintenance Guide”.
● Spinning the rear wheels on slippery sur-
faces may cause the 4WD warning light to
flash. The 4WD system may also automati-
cally 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 emer-
gency. (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 selector lever to the
P (Park) position.
OPERATING RANGE FOR ENGINE
