2-78 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 will be displayed. Press the MODE button until
the proper variance number, as shown on the map, is
showing. Press the RESET button to set the new variance
zone and resume normal operation.
The display will show all the display segments for half a
second 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 ªCALº will be displayed, and all segments
of the compass will be illuminated 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.

2-79
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. Release the button 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 ª
-E-º 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 RESET button for at least two
seconds. The reset is acknowledged with the display
showing all segments on for a period of half a second.
A reset can only be done in AVG ECON, FUEL USED
and AVG SPEED displays.

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.

yellowblue
3-3
DEFOG: 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). Air inlet will also be
automatically set to outside air. The RECIRCULATION
button will not be selectable in this mode.
DEFROST: 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 will not be selectable in
this mode.
OUTSIDE AIR: Press this button to force the
system to use outside air. This button is usable with all
of the mode settings. An indicator on the button will
light up when this button is selected.
RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle. This button is usable in UPPER, LOWER and
BI
-LEVEL modes. An indicator 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.
A/C:Press this button to turn the air conditioning
on and off. The system will cool and dehumidify the air
inside the vehicle when the A/C light is on.

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.

3-7 Rear Window Defogger
The rear window
defogger uses a
warming grid to
remove fog from
the rear window.
Press the button
marked REAR to
turn the defogger on.
An indicator on the
button will light.
The rear window defogger will turn itself off after about
15 minutes. If you turn it on again, the defogger will
only run for about 7.5 minutes before turning off. You
can also turn the defogger off by turning the ignition off
or by 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.
