INSTRUMENT CLUSTER DESCRIPTIONS

1. Speedometer

Indicates vehicle speed.
2. Instrument Cluster Display
When the appropriate conditions exist,
this display shows instrument cluster
display messages Ú page 44.
Odometer/Trip Odometer Display Area
US Federal regulations require that upon
transfer of vehicle ownership, the seller
certify to the purchaser the correct mileage
that the vehicle has been driven. If your
odometer needs to be repaired or serviced,
the repair technician should leave the odom -
eter reading the same as it was before the
repair or service. If the technician cannot do
so, then the odometer must be set at zero,
and a sticker must be placed in the door
jamb stating what the mileage was before the
repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/service, so that you can be
sure that it is properly reset, or that the door
jamb sticker is accurate if the odometer must
be reset at zero.
Gear Selector Status (PRND)
The gear selector status “P,R,N,D,1,2,3,4,5,
6” are displayed indicating the gear selector
position. Telltales “1,2,3,4,5,6” indicate the
manual mode has been engaged and the
gear selected is displayed Ú page 60.

Instrument Cluster Display Location
3. Tachometer
This gauge measures engine revolutions
per minute (RPM x 1000). Before the
pointer reaches the red area, ease up on
the accelerator to prevent engine
damage.
4. Temperature Gauge

The temperature gauge shows engine
coolant temperature. Any reading within
the normal range indicates that the engine
cooling system is operating satisfactorily.

The pointer will likely indicate a higher
temperature when driving in hot weather
or up mountain grades. It should not be
allowed to exceed the upper limits of the
normal operating range.
WARNING!

A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized
dealer for service if your vehicle overheats.

SAFETY189
(Continued)
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have an authorized dealer inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each time
the vehicle is raised for lubrication or oil
change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at
high speed.
WARNING! (Continued)
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.

return the hose to its storage area (located
on top of the housing).
7. Return the Tire Service Kit to its storage location in the vehicle.
JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so please
follow the procedures in this section carefully. NOTE:
When using a portable battery booster pack,
follow the manufacturer’s operating instruc
-
tions and precautions.
PREPARATIONS FOR JUMP START
The vehicle’s jump starting remote posts are
located under the hood, in the engine
compartment on the driver's side.
The Remote Positive (+) Post is covered with a
protective cap located on the side of the Front
Power Distribution Center. The Remote Negative
(-) Post is located on the
core support closest to the front of the vehicle.

Jump Starting Locations

WARNING!
Do not attempt jump starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.(+) Remote Positive Post
(-) Remote Negative Post
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact. You
could be seriously injured.

IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
the engine idle speed while preventing
vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.

WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.
