3-7 Heating (Engine Coolant Heater)
If your vehicle has an engine coolant heater, you can use it
to help your system provide warm air faster when it's cold
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.
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.
For a quick cool
-down on very hot days, use MAX with
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, use VENT with the
temperature levers 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
-LEV and set the temperature levers to a
comfortable setting. 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 others.
Push the A/C button for cooling.
Defogging and Defrosting
If you have the Dual Comfortemp Climate Control, your
system has two settings for clearing the front and side
windows. To defrost the windows quickly, turn the mode
knob to the defrost setting and turn the temperature knob
all the way in the red area.
For maximum defroster performance, set both driver and
passenger temperature controls to the warmest setting.
To warm passengers while keeping the windows clear,
use BLEND.
If you have the Dual Automatic Comfortemp Climate
Control, your system has two settings for clearing the front
and side windows. To defrost the windows quickly, press
the FRONT button, set the temperature to 90
F (32
C),
select high fan speed and turn the DUAL button off. To
warm passengers while keeping the windows clear, push
the AIR FLOW button until WINDSHIELD/FLOOR
appears in the display. Select fan speed for comfort and
windshield clearing performance.

3-8 Rear Window Defogger
Dual ComforTemp

Climate ControlDual Automatic
ComforTemp

Climate Control
The rear window defogger uses a warming grid to
remove fog from the rear window. Press the button to
turn the rear defogger on. It will turn off after about
15 minutes. If you turn it on again, the rear defogger
will only run for about seven and a half minutes before
turning off. You can also turn it off by pressing the
button again.
NOTICE:
Do not attach anything like a temporary vehicle
license or decal across the defogger grid.
NOTICE:
Don't use a razor blade or anything 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.

3-9 Ventilation System
Adjust the direction of
airflow by moving the
vent levers.
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.
If the airflow seems very low when the fan is adjusted
to the highest setting regardless of the mode setting,
your passenger compartment air filter may need to be
replaced. See ªMaintenance Scheduleº or ªPassenger
Compartment Air Filterº in the Index.Ventilation Tips

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.

When you enter a vehicle in cold weather, adjust the
mode knob or button to FLOOR and the fan to the
highest speed for a few seconds before driving off.
This helps clear the intake ducts of snow and
moisture and reduces the chance of fogging the
inside of your windows.

Keep the air path under the front seats clear
of objects. This helps air to circulate throughout
your vehicle.

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

Cassette Tape Messages
If an E and a number appears on the display while trying
to play a cassette tape, it could be for one of the
following reasons:

E10: The tape is tight and the player can't turn
the tape hubs. Remove the tape. Hold the tape with
the open end down and try to turn the right hub
counterclockwise with a pencil. Turn the tape over
and repeat. If the hubs do not turn easily, your tape
may be damaged and should not be used in the
player. Try a new tape to make sure your player is
working properly.

E11: The tape is broken. Try a new tape.
CLN (Clean): If this message appears on the display,
the cassette tape player needs to be cleaned. It will still
play tapes, but you should clean it as soon as possible to
prevent damage to the tapes and player. See ªCare of
Your Cassette Tape Playerº in the Index.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer. If your radio displays an
error number, write it down and provide it to your dealer
