Compass Variance
Compass variance is the difference between magnetic
north and geographic north. In some areas of the
country, the difference is great enough to cause the
compass to give false readings. If this occurs, the
compass variance must be set.
Setting the Variance
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press the RESET
button for approximately five seconds. The last
entered variance zone number and VAR will be
displayed. Press the MODE button until the proper
variance number on the map is shown. Press the
RESET button to set the new variance zone and
resume normal operation.
All the display segments will be illuminated briefly
to acknowledge the change in zone number. A chime
will sound to confirm that the new zone number has
been set.

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 CAL will be displayed, and all segments of
the compass will be illuminated where the compass
reading is normally displayed.
All Segments Illuminated
To calibrate the compass, in an area free from large
metal objects, make one or two 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 the RESET button
for at least 10 seconds until the calibration symbol
appears and all segments of the compass display are
illuminated. A chime will sound to confirm that the
calibration mode is active. Release the button and
complete two or three 360
turns in an area free from
large metal objects. The calibration symbol will turn off
and the compass reading will be displayed. A chime will
sound to verify that the calibration is complete.
Error Displays

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

In the absence of vehicle communications,
a dash (
--) 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. When in a low fuel
condition, LO is displayed.

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 RESET button for at least
three seconds. The reset is acknowledged with the
display showing all segments on briefly and a chime.
A reset can only be done in AVG ECON, FUEL
USED and AVG SPEED displays. Each setting
must be reset individually.

Comfort Controls
Dual ComforTemp
Climate Controls
The Dual ComforTemp Climate Control system allows
the driver and passenger to maintain separate temperature
settings for their seating areas. 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
regulates the fan speed. Turn the fan to 1 for low fan
speed and up to 5 for maximum fan speed.OFF: Turn the fan knob to OFF to turn off the system.
The fan must be on for the air conditioning compressor
to operate.
Driver's Temperature Lever
The lever on the left adjusts the air temperature on
the driver's side of the vehicle independent of the
temperature set by the passenger. Slide the lever
upward to raise the temperature. Slide the lever
downward to lower the temperature.
Passenger's Temperature Lever
The lever on the right adjusts the air temperature on
the passenger's side of the vehicle independent of the
temperature set by the driver. Slide the lever upward to
raise the temperature. Slide the lever downward to
lower the temperature.
Mode Knob
The knob on the right side of the control panel has
several settings to control the direction of airflow:
(Vent): This setting directs air through the
instrument panel outlets.

3-3
(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 small amount to the windshield
defroster and side window outlets.
(Floor): 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. The recirculation
button cannot be selected in this mode.
(Defogger): This setting sends half of the air to
the floor ducts and half to the defroster and side window
outlets. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40
F (4
C). The air inlet will also
be automatically set to outside air. The recirculation
button cannot be selected in this mode.
(Defroster): This setting directs most of the air
through the defroster and side window vents. Some of
the air also goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 40
F (4
C). The air
inlet will also be automatically set to outside air. The
recirculation button cannot be selected in this mode.Mode Buttons
(Outside Air): Press this button to force the
system to use outside air. This button is usable in all of
the air delivery modes on the right knob. An indicator
on the button will light up when this button is selected.
(Recirculation): Press this button to limit
the amount of outside air entering your vehicle. This
is helpful when you are trying to limit odors entering
your vehicle or when you are trying to cool your vehicle
quickly with air conditioning. This button can be used
in vent and bi
-level modes. An indictor on the button
will light up when this button is selected. The system
will default back to the outside air setting, so you will
have to reselect this setting every time you restart
your vehicle.
While in the recirculation mode the system may cause
fogging of the windows when the weather is cold and
damp. To clear the fog, select either the defogger or
defroster mode and increase the fan speed. To avoid
refogging of the windows, use the outside air setting.

3-4
A/C (Air Conditioning Compressor): Press this
button to turn the air conditioning compressor on and
off. An indicator light will glow on this button when the
air conditioning compressor is turned on. The system
will cool and dehumidify the air inside the vehicle when
the A/C light and fan are on.
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, select a fan setting,
turn the right knob on the control panel to vent mode,
press the air conditioning compressor and recirculation
buttons, and move 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, turn the right knob on
the control panel to vent mode; press the air conditioning
compressor and the outside air buttons, and move the
temperature controls 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.
To remedy this, turn the right knob on the control panel
to bi
-level mode. Press the air conditioning compressor
button and move the temperature controls to a
comfortable setting.
Heating
On cold days, turn the right knob on the control panel to floor
mode. Press the outside air button and move the temperature
controls 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 right knob on the control panel
to vent mode, press the outside air button, and move the
temperature controls 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, turn the fan to the
highest setting, and use defroster with the temperature
indicator(s) all the way in the red area. To warm passengers
while keeping the windows clear, use defogger. For more
information, see ªRecirculationº in the Index.

3-5 Rear Window Defogger
Press the button marked
REAR to turn the rear
window defogger on.
An indicator light will
glow when the rear window
defogger button is on.
Press the button again to
turn it off.
When turned on, the rear window defogger uses a
warming grid to remove fog from the rear window.
If your vehicle has the heated outside rearview mirrors,
they will also heat to clear the mirrors surfaces. The
system will automatically turn off after running for
about 15 minutes. If you press the rear window
defogger button again, the system will stay on for
about seven and one half minutes before turning
off again.If in use, the system will shut off when the ignition is
turned off.
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.
