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 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 until the fuel-filler cap
clicks. Failure to tighten the fuel-filler
cap properly may cause the
mal-
function indicator light (MIL) to illumi-
nate. 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 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 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.

The driver’s seat, steering column and
outside mirrors will move to the mem-
orized position or to the exit position
when the entry/exit function is set to
active with the indicator light flashing,
and then the light will stay on for
approximately 5 seconds.

OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air
flow from the foot outlets may not operate.
However, this is not a malfunction. After
the coolant temperature warms up, the air
flow from the foot outlets will operate
normally.
The sensors
*Aand*Blocated on the
instrument panel help maintain a constant
temperature. Do not put anything on or
around the sensors.

CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical systems can cause overrich fuel
flow into the three-way catalyst, causing
it to overheat. Do not keep driving if the
engine misfires, or if noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
. Do not race the engine while warming it
up.
. Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and it is the driver’
s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
