Resynchronization
Resynchronization may be necessary due to the security
method used by this 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
previously been sent. This prevents someone from
recording and playing back the signal from the transmitter.
To resynchronize the transmitter with the receiver, do
the following:
1. Stand close to your vehicle.
2. Simultaneously press and hold the LOCK and
UNLOCK buttons on the transmitter for about seven
seconds. The door locks should cycle (lock and
unlock) to confirm resynchronization.
If the locks do not cycle, see your dealer for service.Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
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 trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

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.

Ashtrays and Cigarette Lighter
The center front ashtray may be on the instrument panel
or on the console. To remove the instrument panel
ashtray, open it, push down on the locking tab and pull
out the ashtray.
Your vehicle may be equipped with a rear ashtray. It is
located within a small door at the rear of your console.
Push on the right side of the door. The ashtray will then
rotate to the right for usage. You can only access the
ashtray by pushing on the door's right side. To remove
the ashtray, push down on the snuffer located in the
middle of the ashtray and lift it out.
NOTICE:
Don't put papers and other things that burn
into your ashtrays. If you do, cigarettes or
other smoking materials could set them on fire,
causing damage.
To use the lighter, just 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.
Sun Visors
To block out glare, you can swing down the visors. You
can also move them from side to side.
Visor Vanity Mirrors
Open the cover to expose the vanity mirror. For the
driver's mirror, slide the cover to the side. For the
passenger's mirror, lift the cover. The lamps will come
on when you open the cover on the passenger's visor.

2-55 Anti-Lock Brake System Active
Light (Option)
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti
-lock brake system
active light will come on.
Slippery road conditions may exist if this light comes
on, so adjust your driving accordingly. The light will
stay on for a few seconds after the system stops
adjusting brake pressure.
The anti
-lock brake system active 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 system is active.
Engine Coolant Temperature Light
This light tells you that
your engine coolant has
overheated or your
radiator cooling fan(s)
are not working.
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.
In ªProblems on the Road,º this manual shows what to
do. See ªEngine Overheatingº in the Index.

2-56 Engine Coolant Temperature Gage
You have a gage that shows
the engine coolant
temperature. If the gage
pointer moves into the red
area, your engine is too hot!
That reading means the same thing as the warning light.
It means that your engine coolant has overheated. 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.
In ªProblems on the Road,º this manual shows what to
do. See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on,
your system is low on
coolant and the engine
may overheat.
See ªEngine Coolantº in the Index and have your
vehicle serviced as soon as you can.

Comfort Controls
Air Conditioning with Electronic Controls
With these systems, you can control the heating, cooling
and ventilation in your vehicle. The systems work best if
you keep your windows closed while using them.
Fan Knob
The right knob with the fan symbol controls the force of
air you want. To turn the fan off, turn the knob to ªO.º
Temperature Control
If your system does not have the auxiliary temperature
control option, the center knob changes the temperature
of the air coming through the system. Turn this knob
toward red (clockwise) for warmer air. Turn it toward
blue (counterclockwise) for cooler air.
If your system does have the auxiliary temperature
control option, the center levers change the temperature
of the air coming through the system. The DRIV lever
sets the temperature for the driver and rear seat
passengers, and the PASS lever sets the temperature for
the front seat passenger. For maximum defroster
performance, set the DRIV and PASS levers at
full warm.

3-4 Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the A/C compressor
load, which should help fuel economy.
For quick cool
-down on very hot days, use MAX with
the temperature control all the way in the blue area. If
this setting is used for long periods of time, the air in
your vehicle may become too dry.
For normal cooling on hot days, use A/C with the
temperature control in the blue area. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. You
can use BI
-LEVEL with the temperature control in the
middle. The system will bring in outside air and direct it to
your upper body, while sending slightly warmed air to
your lower body. You may notice this temperature
difference more at some times than at others.
Heating
On cold days use FLOOR with the temperature control
all the way in the red area. The system will bring in
outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it'scold outside
-- 0
F (-18
C) or lower. An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.
Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window. Press the area
labeled PUSH to turn the
defogger on.

3-5
It will turn itself off after about 10 minutes. If you turn it
on again, the defogger will only run for about five
minutes before turning off. You can also turn it off by
turning off the ignition or pressing the button again.
Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
Don't put decals there because you might have to
scrape them off.
Ventilation System
Adjust the direction of airflow by moving the vents.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
Ventilation Tips

For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle.

Keep the hood and front air inlet free of ice, snow or
any other obstruction, such as leaves. The heater and
defroster will work far better, reducing the chance of
fogging the inside of your windows.
