FUEL-FILLER CAP
WARNING
.Gasoline is extremely flammable
and highly explosive under cer-
tain 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 automatically. Contin-
ued refueling may cause fuel
overflow, resulting in fuel spray
and possibly a fire.
. Use only an original equipment
type fuel-filler cap as a replace-
ment. It has a built-in safety valve
needed for proper operation of
the fuel system and emission
control system. An incorrect cap
can result in a serious malfunc-
tion and possible injury. It could
also cause the malfunction indi-
cator light to come on. .
Never pour fuel into the throttle
body to attempt to start your
vehicle.
. Do not fill a portable fuel contain-
er 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 contain-
ers:
— Always place the container on
the ground when filling.
— Do not use electronic devices when filling.
— Keep the pump nozzle in con- tact with the container while
you are filling it.
— Use only approved portable fuel containers 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 be-
cause 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 the
light does not turn off after a
few driving trips, have the vehicle
inspected. It is recommended you
visit a NISSAN dealer for this
service.
. 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
Mal-
function Indicator Light (MIL) to
illuminate.
Pre-driving checks and adjustments3-35

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 flammable materials such as
dry grass, waste paper or rags.
They may ignite and cause a fire.
CAUTION
.Do not use leaded gasoline. De-
posits from leaded gasoline ser-
iously reduce the three-way
catalyst’s ability to help reduce
exhaust pollutants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel in-
jection, or electrical 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 notice-
able loss of performance or other
unusual operating conditions are
detected. Have the vehicle in-
spected. It is recommended you
visit a NISSAN dealer for this
service.
. 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
recommended by the vehicle manufac-
turer on the vehicle placard or tire infla-
tion 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 deter-
mine 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 illumi-
nates 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 effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity.
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 prop-
erly. The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for
approximately one minute and then re-
