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 sys-
tem malfunction has been detected.
Check the fuel-filler cap if the LOOSE FUEL
CAP warning appears in the trip com-
puter. If the fuel-filler cap is loose or miss-
ing, tighten or install the cap and con-
tinue 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 recommended 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 emis-
sion control system. To reduce or avoid
emission control system damage:– Do not drive at speeds above 45 mph (72 km/h).

•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
malfunction and possible injury. It
could also cause the
Malfunc-
tion Indicator 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 more
than 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 will ap-
pear if the fuel-filler cap is not prop-
erly tightened. It may take a few driv-
ing trips for the message to be
displayed. Failure to tighten the fuel-
filler cap properly af ter the LOOSE
FUEL CAP warning appears 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 illu-
minate. 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 thelight does not
turn off af ter a few driving trips, have
your vehicle inspected. It is recom-
mended that you visit a NISSAN
dealer for this service.

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,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
• Be sure the ignition switch is in the

jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever 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 nec-
essary to work under the vehicle,
support 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.

MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust may form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, refer to
the “Appearance and care” section of this
manual.
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, refer to
