NOTE:The factory default zone is 8. During program-
ming, the zone value will wrap around from zone 15 to
zone 1.
Calibrating the Compass (Mid Line Cluster Only)
If the compass appears erratic, inaccurate, or abnormal,
you may wish to calibrate it. However, prior to calibrat-
ing the compass, make sure the proper Compass Variance
value is selected.
NOTE:The vehicle speed must be at 0 mph (0 km/h)
(manual transmission) or the gear selector lever in ªPº
(Park) (auto transmission) to enter the calibration mode.
To calibrate the compass, first, start the engine. Next,
press and hold the trip odometer button until the current
variance zone number displays (approximately ten sec-
onds). Then, press and hold the button again until the
direction displays with the ªCALº indicator on continu-
ously (approximately ten seconds). Finally, drive thevehicle in one or more complete circles, at speeds under
5 mph (8 km/h), in an area free from power lines and
large metallic objects, until the ªCALº indicator turns off.
The compass will now function normally.
ELECTRONIC VEHICLE INFORMATION CENTER
(EVIC) Ð IF EQUIPPED
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display. It is located at the
bottom of the speedometer in the instrument cluster.
Vehicles equipped with steering wheel mounted buttons
(described in this section) are also equipped with the
EVIC. The EVIC consists of the following:
²System Status
²Vehicle information warning message displays
²Tire Pressure Monitor System (If Equipped)
²Personal Settings (Customer Programmable Features)

²Service Park Assist System (with a single chime)
²Oil Change Required (with a single chime)
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The ªOil Change Requiredº message
will flash in the EVIC display for approximately 10
seconds after a single chime has sounded to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.

Unless reset, this message will continue to display each
time you turn the ignition switch to the ON position. To
turn off the message temporarily, press and release the
Menu button. To reset the oil change indicator system
(after performing the scheduled maintenance) perform
the following procedure:
1. Turn the ignition switch to the ON position (Do not
start the engine).
2. Fully depress the accelerator pedal slowly three times
within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.Trip Functions
Press and release the MENU button until one of the
following Trip Functions displays in the EVIC:
²Average Fuel Economy
²Distance To Empty
²Elapsed Time
²Display Units of Measure in
Press the SCROLL button to cycle through all the Trip
Computer functions.
The Trip Functions mode displays the following informa-
tion:
²Average Fuel Economy
Shows the average fuel economy since the last reset.
When the fuel economy is reset, the display will read
ªRESETº or show dashes for two seconds. Then, the

NOTE:The air conditioning compressor operates in Mix
and Defrost, or a blend of these modes, even if the Air
Conditioning Snowflake button is not pressed. This de-
humidifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
²Recirculation Control
Use this button to block the flow of outside
air from coming into the passenger compart-
ment. A light will illuminate when the sys-
tem is in recirculation mode. Only use the
recirculation mode as a temporary means to block out
any outside odors, smoke, or dust, and to cool the
interior rapidly upon initial start up in very hot or
humid weather.
NOTE:
²Continuous use of the recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
²The use of the recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture build-up inside the vehicle. Select
the Outside Air position for maximum defogging.
²The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.
²The A/C can be deselected manually without disturb-
ing the mode control selection.
Air Conditioning Control
Use this button to engage the Air Conditioning. A
light will illuminate when the Air Conditioning
System is engaged
NOTE:The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.

cabin infrared sensor mounted between the sun-visors
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. Other sensors take account of ve-
hicle speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple.
1. Turn the Mode Control knob (on the right) and the
Blower Control knob (on the left) to AUTO.
NOTE:The AUTO position performs best for front seat
occupants only.2. Dial in the temperature you would
like the system to maintain by rotating
the Temperature Control knob.
Once the comfort level is selected, the system will main-
tain that level automatically using the heating system.
Should the desired comfort level require air conditioning,
the system will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the ªOº (Off) position on the blower control stops the
system completely and closes the outside air intake.
72ÉF (22ÉC) is the recommended setting for maximum
comfort for the average person; however, this may vary.

²Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
Mode by pressing the Recirculation Button. However,
under certain conditions, while in Automatic Mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
Button is pressed, the indicator will flash and then
turn off. This tells you that you are unable to go into
recirculation mode at this time. If you would like the
system to go into Recirculation Mode, you must first
move the Mode Knob to Panel, Panel/Floor and then
press the Recirculation Button. This feature reduces
the possibility of window fogging.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to ªMaintenance Proceduresº in Section 7 of this manual
for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower settings. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
