Instruments and controls2-21

Charge warning light
If this light comes on while the engine is
running, it may indicate the charging sys-
tem is not functioning properly. Turn the
engine off and check the generator belt. If
the belt is loose, broken, missing, or if the
light remains on, have the system checked.
It is recommended that you visit a NISSAN
dealer for this service.
CAUTION
∙ Do not ground electrical accessoriesdirectly to the battery terminal. Doing
so will bypass the variable voltage
control system (if so equipped) and
the vehicle battery may not charge
completely. For additional informa-
tion, refer to “Variable voltage control
system” in the “Do-it-yourself ” sec-
tion of this manual.
∙ Do not continue driving if the genera- tor belt is loose, broken or missing.

Instruments and controls2-25

CAUTION
∙ Continuing vehicle operation withoutproper servicing of the engine control
system could lead to poor driveability,
reduced fuel economy, and damage
to the engine control system, which
may affect the vehicle’s warranty

2-28Instruments and controls

∙ Keep your engine tuned up.
∙ Follow the recommended scheduledmaintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ For vehicles equipped with
, use
4H or 4L position only when necessary.
4-wheel drive operation lowers fuel
economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.
WARNING
∙ For 4WD equipped vehicles, do not at-tempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
∙ Do not attempt to test a 4WD equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions
testing), or similar equipment even if
the other two wheels are raised off the
ground. Make sure you inform test fa-
cility personnel that your vehicle is
equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drive-
train damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal
injury.
CAUTION
∙ Do not drive the vehicle in the 4H or4LO position on dry hard surface
roads. Driving on dry, hard surfaces in
4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning light or vehicle in-
formation display warning message
turns on when you are driving on dry
hard surface roads:
– in the 4H position, shif t the 4WD shif t switch to 2WD.
– in the 4LO position, stop the ve- hicle, move the shif t lever to the N
(Neutral) position with the brake
pedal depressed, and shif t the
4WD shif t switch to 2WD.
∙ If the warning light or vehicle infor- mation display warning message is
still on af ter the above operation,
have your vehicle checked as soon as
possible. It is recommended 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, ap-ply 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 OFF or LOCK position when perform-
ing 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. ∙
The automatic engine cooling fan (if so
equipped) may come on at any time
without warning, even if the ignition
switch is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative bat-
tery cable before working near the fan.
∙ 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.
∙ Because the fuel lines on gasoline en- gine models are under high pressure
even when the engine is off, it is rec-
ommended that you visit a NISSAN
dealer for service of the fuel filter or
fuel lines.
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 automatic
transmission related component har-
nesses disconnected while the igni-
tion 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.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
