you will need to resynchronize the transmitter. To do
this, press the LOCK and UNLOCK buttons on the
transmitter together and hold for approximately
seven seconds or until three brief horn chirps are heard.

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.
CAUTION: (Continued)
CAUTION: (Continued)
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.

or on the console. To remove the instrument panel
ashtray, open it, push down on the locking tab and pull
out the ashtray.
To remove the console ashtray, open the ashtray door,
lift up on the ashtray and pull it out.
The rear ashtray is located within a small door at the rear
of the 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

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.

To block out glare, you can swing down the visors. You
can also move them from side to side. The visors also
have extenders that you can pull out for added coverage.

Engine Coolant Temperature Gage
United
States
-Standard
ClusterUnited
States-Optional
Cluster
Canada
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210
F (100
C) or less. If you are pulling a
load or going up hills, it is normal for the temperature to
fluctuate and approach the 250
F (122
C) mark. If the
gage reaches the 260
F (125
C) mark, it indicates that
the cooling system is working beyond its capacity.
The ªProblems on the Road,º section of this manual shows
what to do. See ªEngine Overheatingº in the Index.

Comfort Controls
Manual Single Zone Climate Control
With this system, you can control the heating, cooling
and ventilation in your vehicle. The system works best if
you keep your windows closed while using it.
Fan Knob
The knob on the left side of the climate control panel controls
the fan speed. To turn the fan off, turn the knob to OFF.
If airflow seems very low when the fan knob is turned to
the highest setting, regardless of the mode setting, your
passenger compartment air filter (if equipped) may need
to be replaced. See ªMaintenance Scheduleº in the Index.Temperature Knob
The center knob on the control panel 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.
Mode Knob
The right knob on the control panel has several settings
to control the direction of airflow:
UPPER: This setting directs air through the
instrument panel outlets.
BI-LEVEL: This setting directs air two ways.
Half of the air is directed through the instrument panel
outlets. Most of the remaining air is directed through the
floor vents and a little to the windshield defroster and
side window outlets.
LOWER: This setting sends most of the air
through the ducts near the floor. The remaining air
comes out of the defroster and side window outlets.

3-6 Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool
-down on very hot days, turn the mode
knob on the control panel to UPPER, push the A/C
button on, push the RECIRCULATION button on and
move the temperature levers 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, turn the mode knob on
the control panel to UPPER, push the A/C button on,
push the OUTSIDE AIR button on and move the
temperature levers all the way 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 turn the mode knob on the control panel to
BI
-LEV, push the A/C button on and move the
temperature levers to a comfortable setting.
Heating
On cold days, turn the mode knob on the control panel
to LOWER, push the OUTSIDE AIR button on and
move the temperature levers all the way in the red area.
The system will bring in outside air, heat it and send it to
the floor ducts.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, turn the mode knob on the control
panel to UPPER, push the A/C button off, push the
OUTSIDE AIR button on and move the temperature
levers to a comfortable setting. Your vehicle also has
the flow
-through ventilation system described later in
this section.
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 indicators turned all the
way in the red area. To warm passengers while keeping
the windows clear, use DEFOG.
