Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds 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.

NOTE: The system will display the last known outside
temperature when starting the vehicle and may need to
be driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect the
displayed temperature; therefore, temperature readings
are not updated when the vehicle is not moving.
ECO (Fuel Saver Mode) — If Equipped
The ECO message will display below the outside tem-
perature in the EVIC display (if the audio system is on
the ECO indicator will override the audio information
display line if the  Display Fuel Saver  personal setting is
ON — see  Personal Settings  section). This message will
appear whenever you are driving in a fuel efficient
manner.
This feature allows you to monitor when you are driving
in a fuel efficient manner, and it can be used to modify
driving habits in order to increase fuel economy. Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to set the compass manually. When the vehicle is
new, the compass may appear erratic and the EVIC will
display “CAL” until the compass is calibrated. You may
also calibrate the compass by completing one or more
360–degree turns (in an area free from large metal or
metallic objects) until the “CAL” message displayed in
the EVIC turns off. The compass will now function
normally.
NOTE: A good calibration requires a level surface and an
environment free from large metallic objects such as build-
ings, bridges, underground cables, railroad tracks, etc.

Manual Compass Calibration
If the compass appears erratic and the “CAL” indicator
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually as follows:
1. Start the engine. Leave the shift lever in PARK in order
to enter the EVIC Programming Menus.
2. Press the MENU button until Personal Settings
(Customer-Programmable Features) displays in the
EVIC.
3. Press the DOWN button until “Calibrate Compass”
displays in the EVIC.
4. Press and release the SELECT button to start the
calibration. The “CAL” indicator will display in the
EVIC. 5. Complete one or more 360–degree turns (in an area
free from large metal or metallic objects) until the
“CAL” indicator turns off. The compass will now
function normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences and provide the most accurate compass head-
ing.
NOTE: Magnetic materials should be kept away from
the top of the instrument panel; this is where the compass
sensor is located.328 UNDERSTANDING YOUR INSTRUMENT PANEL

To Change The Compass Variance:
1. Turn the ignition switch RUN (it is not necessary to
start the engine).
2. Press the MENU button until Personal Settings
(Customer-Programmable Features) displays in the EVIC. 3. Press the DOWN button until “Compass Variance”
message and the last variance zone number displays
in the EVIC.
4. Press and release the SELECT button until the proper
variance zone is selected according to the map.
5. Press and release the COMPASS button to exit.
Average Fuel Economy
Shows the average fuel economy since the last reset.
Average Fuel Economy can be reset by pressing and
holding the SELECT button (as prompted in the EVIC
display). Upon reset, the history information will be
erased, and the averaging will continue from the last fuel
average reading before the reset.Compass Variance Map

NOTE:
• Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
• The use of the Recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Select
the outside air position for maximum defogging.
• The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or Bi-Level.
• The A/C can be deselected manually without disturb-
ing the mode control selection.
• When the ignition switch is turned to the LOCK
position, the recirculation feature will be cancelled. Air Conditioning Control
Press this button to engage the Air Con-
ditioning. A light will illuminate when
the Air Conditioning system is engaged.
Rotating the dial left into the blue area
of the scale indicates cooler tempera-
tures, while rotating right into the red
area indicates warmer temperatures.
NOTE: The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.
• MAX A/C
For maximum cooling, turn on the A/C and recirculation
buttons at the same time.
• ECONOMY MODE
If economy mode is desired, press the A/C button to turn
OFF the indicator light and the A/C compressor. Then,
move the temperature control to the desired temperature. 4 UNDERSTANDING YOUR INSTRUMENT PANEL 395

• Most 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, Bi-Level 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 conditions. 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 solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” 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
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again. 4 UNDERSTANDING YOUR INSTRUMENT PANEL 401

Normal Starting
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
Turn the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Tip Start Feature – Automatic Transmission Only
Turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will continue to run, but will automatically disengage
itself when the engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure. Extreme Cold Weather (Below –20°F Or 29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!• Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and, once the
engine has started, ignite and damage the converter
and vehicle. (Continued)
