The light comes on when the hill descent
control system is activated.
If the hill descent control switch is on and
the indicator light blinks, the system is not
engaged.
If the indicator light does not come on
when the hill descent switch is on, the sys-
tem may not be functioning properly. Have
the system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
For additional information, refer to “Hill de-
scent control switch” in this section and “Hill
descent control system” in the “Starting
and driving” section of this manual.
Malfunction Indicator Light(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may
indicate a potential emission control mal-
function.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least
3 gal (11.4 L) of fuel in the fuel tank. Af ter a few driving trips, the
light
should turn off if no other potential emis-
sion control system malfunction exists.
If this indicator light comes on steady for
20 seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance
test. For additional information, refer to
“Readiness for inspection/maintenance
(I/M) test” in the “Technical and consumer
information” section of this manual.
Operation
The MIL will come on in one of two ways:
∙ MIL on steady — An emission control system malfunction has been de-
tected. Check the fuel-filler cap if the
LOOSE FUEL CAP warning appears in
the trip computer. If 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 inspected. It is recom-
mended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer. ∙ MIL blinking — An engine misfire has
been detected which may damage the
emission control system. To reduce or
avoid emission control system dam-
age:
– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or decelera- tion.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on
steady. Have the vehicle inspected. It is rec-
ommended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.

Failure to do so could cause the hood
to fly open and result in an accident.
∙ If you see steam or smoke coming from the engine compartment, to
avoid injury do not open the hood.
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 contactwith the container while you are
filling it.
– Use only approved portable fuel containers for flammable liquid.
CAUTION
∙ The LOOSE FUEL CAP warning mes-sage will be displayed if the fuel-filler
cap is not properly tightened. It may
take a few driving trips for the mes-
sage to be displayed. Failure to
tighten the fuel-filler cap properly af-
ter the LOOSE FUEL CAP warning mes-
sage is displayed may cause the
Malfunction Indicator Light (MIL) to
illuminate. ∙ Failure to tighten the fuel-filler cap
properly may cause the
Mal-
function Indicator Light (MIL) to illumi-
nate. 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 af ter a
few driving trips. If the
light does
not turn off af ter a few driving trips,
have the vehicle inspected. It is rec-
ommended that you visit a NISSAN
dealer for this service.
∙ For additional information, refer to the “Malfunction Indicator Light (MIL)”
in the “Instruments and Controls” sec-
tion in this manual.
∙ If fuel is spilled on the vehicle body, flush it away with water to avoid paint
damage.
Fuel recommendation

recommendation (if so equipped):
∙ Only vehicles with the E-85 filler door
label can operate on up to E-85 fuel.
Fuel system or other damage can oc-
cur if up to E-85 fuel is used in vehicles
that are not designed to run on E-85
fuel. For additional information, refer
to “Flexible Fuel Vehicle (FFV) fuel rec-
ommendation” in the “Technical and
consumer information” section of this
manual.
Fuel recommendation

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙ Park the vehicle on a level surface, ap-ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shif t lever
to N (Neutral). For Automatic Trans-
mission (A/T) move the shif t lever to P
(Park)
∙ Be sure the ignition key is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine run- ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle. ∙ Always wear eye protection whenever
you work on your vehicle.
∙ If you must run the engine in an en- closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ On gasoline engine models, the fuel filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off.
It is recommended that you visit a
NISSAN dealer for this service.
CAUTION
∙ Do not work under the hood while theengine is hot. Turn the engine off and
wait until it cools down. ∙
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
∙ Never leave the engine or the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
