gauge
Indicates the temperature of the
engine coolant. At normal
operating temperature, the needle
remains within the normal area. If
it enters the red section, the
engine is overheating. Switch off
the ignition and let it cool. Refer to

Voltage gauge
If the pointer moves and stays
outside of the normal range, it
indicates that the battery is not
being charged. Have the vehicle's
electrical system checked by your
dealer as soon as possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle
remains in the normal range. If the
gauge indicates constantly low
pressure at normal engine speed,
refer toChecking and adding
engine oilin theMaintenance
and carechapter. If the gauge
indicates a low pressure and the
engine oil level is correct, switch
off the engine immediately and
have your vehicle checked at your
dealer.

STARTING YOUR VEHICLE
Important safety precautions
A computer system controls the
engine's idle revolutions per
minute (RPM). When the engine
starts, the idle RPM runs faster to
warm the engine. If the engine idle
speed does not slow down
automatically, have the vehicle
checked. Do not allow the vehicle
to idle for more than ten minutes.
Extended idling at high
engine speeds can produce
very high temperatures in the
engine and exhaust system,
creating the risk of fire or other
damage.
Do not park, idle, or drive
your vehicle in dry grass
or other dry ground cover. The
emission system heats up the
engine compartment and exhaust
system, which can start a fire.
Do not start your vehicle
in a closed garage or in
other enclosed areas. Exhaust
fumes can be toxic. Always open
the garage door before you start
the engine. SeeGuarding
against exhaust fumesin this
chapter for more instructions.

3. Turn the key to the ON position
(without turning the key to
START).
Make sure the following lights
illuminate briefly. If a light fails to
illuminate, have the vehicle
serviced.
²If the driver's safety belt is
fastened, the
light does not
illuminate.

the vehicle. Using the heater for
longer than three hours will not
harm the engine, so the heater can
be plugged in the night before
starting the vehicle.
To prevent electrical
shock, do not use your
heater with ungrounded
electrical systems or
two-pronged (cheater) adapters.
Guarding against exhaust
fumes
Although odorless and colorless,
carbon monoxide is present in
exhaust fumes. Take precautions
to avoid its dangerous effects.
If you ever smell exhaust
fumes of any kind inside
your vehicle, have your dealer
inspect and fix your vehicle
immediately. Do not drive if you
smell exhaust fumes. These
fumes are harmful and could kill
you.
Have the exhaust and body
ventilation systems checked
whenever:
²the vehicle is raised for service
²the sound of the exhaust system
changes
²the vehicle has been damaged in
a collision

that could damage drive
components.
If the transmission and transfer
case are submerged in water, their
fluids should be checked and
changed, if necessary.
If the rear axle is submerged in
water, the rear axle lubricant
should be checked and changed, if
necessary. The rear axle is filled
with a synthetic lubricant and does
not normally require a lubricant
change for the life of the vehicle.
Rear axle lubricant quantities
should not need to be checked
unless a leak is suspected.
Driving on hill or slope terrain
When driving on a hill, avoid
driving crosswise or turning on
steep slopes. You could lose
traction and slip sideways. Drive
straight up, straight down or avoid
the hill completely. Know the
conditions on the other side of a
hill before driving over the crest.
When climbing a steep hill, start in
a lower gear rather than
downshifting to a lower gear from
a higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of
stalling.
