2-103
Setting the Variance
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for approximately five
seconds. The last entered variance zone number will be
displayed. Press the E/M button until the proper
variance number, as shown on the map, is showing.
Press the MODE button to set the new variance zone
and resume normal operation.The display will show all the display segments briefly to
acknowledge the change in zone number.
Automatic Compass Calibration
The compass is self
-calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases the calibration symbol ªCº will be displayed
where the compass reading is normally displayed.
To calibrate the compass, in an area free from large
metal objects, make three 360
turns. The calibration
symbol will turn off and the compass reading will
be displayed.
Manual Compass Calibration
If the compass appears erratic and the calibration
symbol does not appear, you must manually put the
compass into the calibration mode.
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for at least 10 seconds
until the calibration symbol appears. Release both
buttons and complete three 360
turns in an area free
from large metal objects. The calibration symbol will
turn off and the compass reading will be displayed.

Error Displays

An error of the vehicle's speed sensor or fuel sender
will cause
-E- to be displayed.

In the absence of vehicle communications, a double
dash ª
--º is displayed.
If one of these error messages appear, see your dealer.
Trip Computer
There are five trip computer displays which may be
stepped through by pushing the MODE button. The
information will appear in the following order:

AVG ECON (Average Fuel Economy): This shows
the average fuel economy since the last reset.

INST ECON (Instantaneous Fuel Economy): This
shows fuel economy for the most recent second
of driving.

RANGE (Trip Range): This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based on
the last few hours of driving.

FUEL USED (Trip Fuel Used): This shows the
accumulated fuel used since the last reset.

AVG SPEED (Average Speed): This shows the
average speed since the last reset.
Resetting the Trip Computer
Press and hold the MODE and E/M buttons for at least
two seconds. The reset is acknowledged with the display
showing all segments on briefly. A reset can only be
done in AVG ECON, FUEL USED and AVG SPEED
displays. AVG ECON, FUEL USED and AVG SPEED
can be reset independently. Only the mode that is
displayed will be reset.

DEFOG: This setting directs air to the
windshield and through the floor ducts. This mode is
useful during cold or inclement weather because of your
vehicle's larger windshield area.
DEFROST: This setting directs most of the air to
the windshield and side window vents.
Mode Buttons
OUTSIDE AIR: Press this button
(the light will glow) to send outside air into your
vehicle. Using this setting while trying to defrost or
defog the windows will help clear the vents of moisture.
Press the RECIRCULATION button (the light on the
OUTSIDE AIR button will go off) to limit outside air
entering the vehicle. When the DEFOG or DEFROST
setting is selected, the system will automatically go to
OUTSIDE AIR mode.
RECIRCULATION: Press this button
(the light will glow) to limit the amount of fresh air
entering your vehicle by recirculating much of the air
inside your vehicle. You may use this setting to limit
odors entering your vehicle. Press the OUTSIDE AIR
button (the light on the RECIRCULATION button will
go off) to let outside air circulate into the vehicle.Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the RECIRCULATION mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
HVAC system to either the DEFOG or DEFROST mode
and increase the fan speed. To avoid re
-fogging of
the windows, operate the HVAC system in the
OUTSIDE AIR mode.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature control knob and fan speed
as desired.
To get maximum cooling or a quick cool
-down on very
hot days, press the A/C and RECIRCULATION buttons
(the lights will glow) and turn the temperature knob
counterclockwise (toward the blue area). Adjust the
mode knob to direct the air to the desired location.
This setting should not be used for long periods of time
because the air may become too cold and dry. Push the
A/C button again (the light will go off) to turn off the
air conditioning.

When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle's engine compartment when it is idling or
after it has been turned off. This is normal.
Heating
Turn the temperature knob clockwise (toward the red
area) to warm the air.
In the LOWER setting, outside air will be brought in
and sent through the floor outlets. The heater works best
if you keep your windows closed while using it.
The BI
-LEVEL setting is designed for use on sunny
days when the air is only moderately warm or cool.
On days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. For the best results, turn the temperature
control knob to the middle position, and then adjust it
for comfort.If you have the optional engine coolant heater and use it
during cold weather, 0
F (
-18
C) or lower, your heating
system will provide heat more quickly because the
engine coolant is already warmed. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
To rapidly defrost the windshield, turn the temperature
control knob all the way clockwise (to the red area) and
turn the mode knob to DEFROST. Adjust the fan to the
highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob
to DEFOG.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the BI
-LEVEL setting and adjust the fan to the
highest speed. Aim the side vents on the instrument
panel toward the side windows. For increased airflow to
the side vents, close the center vents.

3-7
Turn the temperature knob counterclockwise (to the blue
area) for cooler air, or clockwise (to the red area) for
warmer air.
To maintain a comfortable temperature in the rear, use
either rear fan control to adjust the force of air coming
through the rear outlets.
Select the desired climate control mode using the
directional controls on the instrument panel (see ªMode
Knobº earlier in this section). The mode you choose will
regulate both the front and rear climate control systems.Rear Air Vents
To maximize airflow through the rear heater outlet, place
the left bucket seat in the second row in the forward
position (see ªAdjusting Rear Seatsº in the Index).
The vent behind the left rear seat is the cold air return
vent. Be sure to keep it free of obstructions.
Keep the area around the base of the center instrument
panel console, between and under, the front seats free of
objects that could obstruct airflow to the rear.

Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
If you have power door locks, your vehicle has a feature
called Retained Accessory Power (RAP). With RAP,
you can play your audio system even after the ignition is
off. See ªRetained Accessory Powerº in the Index.
