FUEL-FILLER CAP
WARNING
∙ Gasoline is extremely flammable andhighly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the 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 af ter 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 emission control system. An in-
correct cap can result in a serious mal-
function and possible injury. It could
also cause the
Malfunction Indi-
cator 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 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
∙ Do not use a fuel containing morethan 15% ethanol in your vehicle. For
additional information, refer to “Fuel
recommendation” in the “Technical
and consumer information” section of
this manual. ∙
The LOOSE FUEL CAP warning message
will appear if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the message to be dis-
played. Failure to tighten the fuel-filler
cap properly af ter the LOOSE FUEL CAP
warning message appears may cause
the
Malfunction Indicator Light
(MIL) to illuminate.
∙Failure to tighten the fuel-filler cap
properly may cause the
Malfunc-
tion Indicator Light (MIL) to illuminate. If
the
light 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 af ter a few driving trips.
If the
light does not turn off af ter
a few driving trips, have the vehicle in-
spected. It is recommended that you
visit a NISSAN dealer for this service.
∙ For additional information, refer to “Malfunction Indicator Light (MIL)” in
the “Instruments and controls” sec-
tion of this manual.

tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves 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.
∙ Do not use the recirculation mode for long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.
NOTE: ∙
Odors from inside and outside the ve-
hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
∙ When parking, set the heater and air
conditioner controls to turn off air re-
circulation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.
