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.

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.
