2-81 Door/Trunk Ajar Warning Light
The DOOR/TRUNK light
will come on if your trunk
or any door is not
completely closed.
Fuel Gage
United States CanadaYour fuel gage tells you about how much fuel you have
left when the ignition is on. When the indicator nears
empty, you still have a little fuel left, but you should
get more soon.
Here are four things that some owners ask about. All
these things are normal and do not indicate that anything
is wrong with the fuel gage:

At the gas station, the pump shuts off before the gage
reads full.

It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's capacity
to fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate empty when the ignition
is turned off.

2-82 Low Fuel Light
United States Canada
If your fuel is low, a circular light on your instrument
panel cluster will come on and stay on and a chime will
sound periodically until you add fuel.
It will also come on for a few seconds when you first
turn on the ignition as a check to show you it's working.
If it doesn't come on then, have it fixed.
Driver Information Center (Option)
The Driver Information Center (DIC), located below the
tachometer on the instrument panel cluster, gives you
important safety and maintenance facts. When you turn
the ignition on, the entire center lights up for just a
few seconds.

Control Buttons
The Driver Information Center has three buttons that
control its functions.
The English/Metric (E/M), RESET and MODE
buttons for the Driver Information Center are located to
the left of the steering wheel, just below the instrument
panel cluster.
E/M (English/Metric): Press this button to change
the display from English to metric units or metric
to English.
RESET: Press this button for one second to reset the
mode displayed.
MODE: Press this button to change the mode
being displayed.

2-84 Modes
AVG ECON (Average Economy): Shows your average
fuel economy since you last reset this mode. Average
fuel economy is viewed as a long term approximation of
your overall driving and driving conditions. To learn the
average fuel economy from a new starting point, press
the RESET button while the average fuel economy is
displayed in the DIC.
INSTANTANEOUS FUEL ECONOMY: Shows your
current fuel economy. Instantaneous fuel economy
varies with your driving conditions, such as
acceleration, braking and the grade of the road being
traveled. The instantaneous fuel economy display cannot
be reset, therefore the reset button has no effect while in
this mode.OIL LIFE MONITOR: Shows an estimate of the oil's
remaining useful life. When the oil life index is less than
10%, the CHANGE OIL SOON light will come on.
When you have the oil changed according to the
maintenance schedule (see ªMaintenance Scheduleº in
the Index), you will have to reset the CHANGE OIL
SOON light.
To reset the CHANGE OIL SOON light, see ªOil Life
Systemº in the Index.
Also, see ªEngine Oil, When to Changeº and
ªMaintenance Scheduleº in the Index.
RANGE: Shows the approximate distance you can
drive without refueling. This is based on the amount of
fuel in the tank and on the fuel economy of the most
recent 25 miles (40 km). Pressing RESET while in this
mode will have no effect.
BOOST GAGE: If you have the supercharged engine,
this gage will show the amount of boost your engine is
receiving. Pressing RESET while in this mode will have
no effect.

Comfort Controls
Dual ComforTemp
Climate Control
With this system, the driver and passenger can maintain
separate temperatures in their seating areas. The system
works best if you keep your windows closed while using it.
FAN:
Turn the knob clockwise toward HI to increase fan
speed and counterclockwise toward LO to decrease
fan speed. The fan must be turned on for the air
conditioning compressor to operate.
If the airflow seems very low when the fan is adjusted
to the highest setting regardless of the mode setting,
your passenger compartment air filter may need to be
replaced. See ªMaintenance Scheduleº or ªPassenger
Compartment Air Filterº in the Index.
OFF: To turn off the fan, turn the knob all the way
counterclockwise to off.
DRIVER (Driver's Side Temperature):
The lever on the left adjusts the air temperature on the
driver's side outlets independent of the temperature set by
the passenger. Slide the lever up to raise the temperature.
Slide the lever down to lower the temperature.
PASSENGER (Passenger's Side Temperature):
The lever on the right adjusts the air temperature on the
passenger's side independent of the temperature set by
the driver. Slide the lever up to raise the temperature.
Slide the lever down to lower the temperature.

3-3
Mode Knob
The right knob has several settings to control the
direction of airflow. To access the various modes
available, turn the mode knob to the desired mode.
MAX (Maximum Air Conditioning): This setting
recirculates much of the air inside your vehicle and
sends it through the instrument panel outlets. The air
conditioning compressor will run automatically in this
setting unless the outside temperature is below 40
F
(4
C). (Even when the compressor is running, you can
control the temperature.)
VENT (Ventilation): This setting brings in outside air
and directs it through the instrument panel outlets.
BI
-LEV (Bi-Level): This setting brings in outside air
and directs it two ways. Half of the air is directed
through the instrument panel outlets. Most of the
remaining air is directed through the floor ducts and a
little to the defrost and side window vents.
HTR (Heater): This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defroster and side window vents.BLEND: This setting allows half of the air to go to the
floor ducts and half to the defroster and side window
vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40
F (4
C). (Even when the
compressor is running, you can control the temperature.)
DEF (Defrost): This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts and the side window vents.
The air conditioning compressor will run automatically
in this setting unless the outside temperature is below
40
F (4
C). (Even when the compressor is running,
you can control the temperature.)
Mode Button
A/C (Air Conditioning): 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.

3-4 Dual Automatic ComforTemp
Climate
Control (If Equipped)
With this system, you set a temperature. You can then
either let the system automatically control airflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best if you
keep your windows closed while using it.
Manual Control
If you prefer to manually control the heating,
cooling and ventilation in your vehicle, you can
select airflow direction, fan speed, outside or
recirculated air, air conditioning and temperature.AIR FLOW: This control has several settings to
control the direction of airflow when the system is
not in AUTO.
To access the various modes available, continue to press
the AIR FLOW rocker switch up or down until the
desired mode appears in the display.
WINDSHIELD/FLOOR: This setting directs half of
the air to the floor ducts and half to the defroster and
side window vents. The air conditioning compressor
will run automatically in this setting unless the outside
temperature is below 40
F (4
C).
MID/FLOOR (Instrument Panel/Floor): This setting
directs half of the air through the instrument panel
outlets. Most of the remaining air is directed through
the floor ducts and a little to the defroster and side
window vents.
MID (Instrument Panel): This setting directs air
through the instrument panel outlets.
FLOOR: This setting sends most of the air through the
ducts near the floor. The rest comes out of the defroster
and side window vents. When in this setting and the
RECIRC setting, the windows can fog up. See
ªRecirculationº in the Index.
