2-11 Resynchronization
Resynchronization may be necessary due to the security
method used by the remote keyless entry system. The
transmitter does not send the same signal twice to the
receiver. The receiver will not respond to a signal it has
been sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize the transmitter with the receiver, stand
close to your vehicle, and at the same time press and
hold the LOCK and UNLOCK buttons on the
transmitter for about eight seconds. The door locks
should cycle and the parking lamps should flash to
confirm synchronization. If this does not happen, you
may need to replace the battery in your transmitter or
match the transmitter to your vehicle.
Hatch
CAUTION:
It can be dangerous to drive with the hatch open
because carbon monoxide (CO) gas can come into
your vehicle. You can't see or smell CO. It can
cause unconsciousness and even death.
If you must drive with the hatch open or if
electrical wiring or other cable connections must
pass through the seal between the body and
the hatch:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT. That will force outside air into
your vehicle. See ªComfort Controlsº in
the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

To use the lighter, push it in all the way and let go.
When it's ready, it will pop back by itself.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
If you plug accessories into your cigarette lighter, such
as heating devices or air compressors, these accessories
should have a rated current of less than 15 amps.
Exceeding this limit will result in a blown fuse.
Sun Visors
To block out glare, you can swing down the visors.
You can also swing them to the side.
Visor Vanity Mirror
Pull down the sun visor and lift the cover to expose
the vanity mirror.
Accessory Plug
This plug is located behind a closed lid in front of the
parking brake on the console. The plug can be used to
connect electrical equipment such as a cellular phone or
a CB radio. Be sure to follow the installation
instructions included with the equipment.

2-82 Low Traction Light
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
If you have the traction control system, this light will also
come on when the system is limiting wheel spin. You
may feel or hear the system working, but this is normal.
Slippery road conditions may exist if the low traction
light comes on, so adjust your driving accordingly. The
light will stay on for a few seconds after the traction
control system stops limiting wheel spin.
The low traction light also comes on briefly when you turn
the ignition key to RUN. If the light doesn't come on
then, have it fixed so it will be there to tell you when the
anti
-lock brake system or traction control system is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area, your engine
is approaching an
overheating condition.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.

2-83 Low Coolant Light (5.7L V8 Engine)
This warning light should
come on briefly while you
are starting your engine.
If the light doesn't come
on, have it repaired.
Your vehicle is equipped with a low coolant indicator
that is designed to detect when the coolant level drops
below a set limit. If the coolant level sensor (on the
radiator) detects that the level drops while the engine is
running, the low coolant indicator will light and remain
lit until the ignition is turned to OFF. Check coolant
level and add coolant as needed. The low coolant light
might stay on after filling the radiator. Turn the ignition
to OFF, then restart the engine to verify that the low
coolant light goes out. See ªEngine Coolantº in
the Index.NOTICE:
Driving with the low coolant light on could cause
your vehicle to overheat. See ªEngine Overheatingº
in the Index. Your vehicle could be damaged and
it wouldn't be covered by your warranty.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.

Comfort Controls
With this system you can control the heating, air
conditioning and ventilation in your vehicle.
Your vehicle also has the flow
-through ventilation
system described later in this section.
Fan Control Knob
Turn the fan knob to select the force of air
you want.Temperature Control Knob
Turn the center knob to change the temperature of the
air flowing from the system. Turn it toward the red
(clockwise) for warmer air and toward the blue
(counterclockwise) for cooler air.
Air Control Knob
OFF: The system is off.
MAX: Provides maximum cooling or quick cool
-down
on very hot days. This setting recirculates most of the air
inside your vehicle. If it is used for long periods of time
the air may become dry. This setting directs air through
the upper air vents.
A/C: Use for normal cooling on hot days. This setting
cools outside air and directs it through the upper air vents.
The air conditioner compressor operates in MAX, A/C,
bi
-level, blend and defrost when the outside temperature
is above freezing. When the air conditioner is on, you
may sometimes notice slight changes in your vehicle's
engine speed and power due to the operation of
the compressor.

BI-LEVEL: Air is directed through the upper air
vents and the heater ducts.
VENT: Air flows through the upper air vents.
HEATER: This setting directs most of the air
through the heater ducts and some of the air through the
windshield defroster vents.
BLEND: Air is directed through the windshield
defroster vents and the heater ducts.
DEFROST: This setting directs most of the air
through the windshield defroster vents and some of the
air through the heater ducts.
Cooling
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.
1. Turn the air control knob to A/C for normal cooling.
For faster cooling turn the knob to MAX.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.
Heating
The heater works best if you keep your windows closed
while using it.
1. Turn the air control knob to heater.
2. Turn the fan control knob to the desired speed.
3. Turn the temperature control knob to a
comfortable setting.
During initial start
-up only, if your vehicle is equipped
with an optional engine coolant heater, you can use it in
cold weather (around +20
F/
-8
C or lower) to improve
heater performance on initial start up. See ªEngine
Coolant Heaterº in the Index.
Bi-Level Heating
You may want to use bi-level heating on cool, but sunny
days. This setting directs cool air toward your body and
warmer air toward your feet.
1. Turn the air control knob to bi
-level.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.

3-4 Ventilation
For mild outside temperatures when little heating or
cooling is needed, you can still direct outside air through
your vehicle.
1. Turn the air control knob to vent.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.
Defogging and Defrosting
1. Turn the air control knob to defrost.
2. Turn the temperature control knob to the
desired setting.
3. Turn the fan control knob to the desired speed.
The side window defogging works equally as well in the
heater, blend and defrost modes.
Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the button to turn on the defogger. An indicator
light will come on to remind you that the defogger is on.
The defogger will turn off automatically after about 10
minutes of use. If you turn it on again, the defogger will
operate for about five minutes only. You can turn the
defogger off by pressing the button again. The indicator
light will go off when the system is turned off.
Do not attach anything like a temporary vehicle license
or a decal across the defogger grid on the rear window.
