The CRUISE light comes
on when you set the
vehicle's cruise control.
See ªCruise Controlº
in the Index.
Fuel Gage
United States CanadaThe fuel gage shows about how much fuel is in your
tank. It works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel warning light will come on and a
chime will sound. You still have a little fuel left, but
you need to get more fuel right away.
Here are some things that some owners ask about.
None of these show a problem with your fuel gage:

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

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

The gage moves up a little when you turn a corner,
speed up or make a hard stop.

The gage doesn't go back to empty when you turn
off the ignition.

Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver
Information Center (DIC). The DIC will display
information about how your vehicle is functioning,
as well as warning messages if a system problem is
detected. This feature also allows two different drivers
to store and recall their own personal choice settings.
See ªDIC Personal Choice Programmingº later in
this section.
DIC Displays and Controls
There are two lines in the DIC display. The DIC
displays the driver number identified when entering the
vehicle. You can have your dealer program your name to
appear on this display line. See your dealer for more
information.
When you turn the ignition on, the DIC will display
your DRIVER NUMBER. The system will then perform
a status check and display any messages if a problem
is detected.
If there are no problems detected, the display will return
to the mode selected by that driver the last time the
ignition was turned off.If a problem is detected, a diagnostic message will
appear in the display. The following pages will show
the messages you may see on the DIC display.
The message center is continuously updated with the
vehicle's performance status.
The following buttons are
on the DIC control panel
which is located to the left
of the steering column:
ODO/TRIP (Odometer/Trip): When this button is
pressed, the display will show the total mileage, and
Trip 1 or Trip 2 miles. Trip 1 and Trip 2 will display the
miles traveled since the last reset. To reset the trip
odometer, press the ODO/TRIP button until the
preferred trip number (1 or 2) is shown in the DIC
display, then press the RESET button. The trip odometer
will now accumulate miles until the next reset.

2-86
When the STABILITY SYSTEM ACTIVE message is
on, you should continue to steer in the direction you
want to go. The system is designed to help you in bad
weather or other difficult driving situations by making
the most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on,
you'll know that something has caused your vehicle to
start to spin, so you should consider slowing down.
DIC Personal Choice Programming
The DIC can be used to program the following personal
choice features available with your vehicle:

Automatic Door Locks

Window Lockout

Security Feedback

Delayed Locking

Perimeter Lighting

Memory Seats (If Equipped)

Tilt Mirrors (If Equipped)

Driver ID ON/OFF

Language SelectionFor vehicles not equipped with a DIC, see ªPersonal
Choice Programmingº in the Index.
The personal choice settings displayed on the DIC are
determined by the transmitter used to enter the vehicle.
Each remote keyless entry transmitter was
pre
-programmed to belong to DRIVER 1 or DRIVER 2
and is numbered on the back. After the button with the
unlock symbol on a remote keyless entry transmitter is
pressed and the ignition is in RUN, the DIC will display
the identified driver and recall the settings previously
programmed for that driver. The settings can also be
recalled by briefly pressing one of the MEMORY
buttons located on the driver's door.
If you unlock the vehicle using your door key instead of
your transmitter, the DIC will not change drivers and
will recall the information from the last transmitter used
or the last driver using the memory seat controls. If this
happens and you were not the last driver of the vehicle,
simply press your correct driver number on the memory
seat controls or press the button with the unlock symbol
on your remote keyless entry transmitter.

3. Now press the image height adjuster switch to
position the image as low as possible, while still
keeping it in full view.
4. Slide the dimmer lever downward until the HUD
image is no brighter than necessary.
To turn the HUD display off, slide the dimmer lever
all the way down.
If the sun comes out and the sky becomes cloudy,
you may need to adjust the HUD brightness using
the dimmer lever. Polarized sunglasses could make
the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of the
steering column.
Clean the inside of the windshield as necessary to
remove any dirt or film that reduces the sharpness
or clarity of the HUD image.To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.
If the ignition is on and you can't see the HUD image,
check to see if:

Something is covering the HUD unit.

The HUD dimmer lever is adjusted properly.

The HUD image is adjusted to the proper height.

A fuse is blown. See ªFuses and Circuit Breakersº
in the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD
or your HUD image may look blurred or out of focus.

OFF: If the passenger comfort control is turned on, it
can be turned off by pressing the OFF button once.
Pressing the OFF button a second time will turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to be directed toward the
floor. The system will still try to keep the interior of the
vehicle at the previously chosen temperature setting.
The outside temperature will show on the display when
the system is off.
The ventilation system always allows fresh air to flow
through your vehicle when the vehicle is moving even
when the system is off.
VENT (Flow
-Through Ventilation): The VENT
button allows outside air to flow through your vehicle
without the air conditioning compressor working. To
turn off the VENT selection, push the VENT button
again. If you select VENT while in FRONT defrost, the
VENT light will flash three times to let you know this is
not allowed. This is to prevent fogging.RECIRC (Recirculation): When RECIRC is selected,
the system will limit the amount of outside air entering
your vehicle. This is helpful when you are trying to cool
the interior of the vehicle quickly or limit the amount of
outside air entering your vehicle. RECIRC and AUTO
may be selected at the same time. The system will remain
in RECIRC until the ignition is turned off or the RECIRC
button is pressed again. RECIRC can be selected in all
manual airflow modes except FRONT defrost and VENT.
If you select RECIRC while in FRONT defrost, the
RECIRC light will flash three times to let you know this is
not allowed. This is to prevent fogging. FRONT: This selection is used to defrost
the windshield by directing the airflow toward the
windshield. To turn off FRONT, press the AUTO
or AIR FLOW button.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the windshield and the floor. If the AIR FLOW
down button is selected while in the FRONT defrost
mode, the system will direct the air toward the floor, and
the FRONT defrost mode will cancel.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.

Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your temperature setting. The system may
supply cooler air to the side of the vehicle toward the
sun. Be careful not to put anything over the sensor on
top of the dash.
The display will show fan speed, temperature level
setting and airflow direction for a few seconds whenever
AUTO is selected, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving. During stops, the
display shows the previous temperature for best
accuracy and system control.
To find your preferred temperature setting, start with the
system in AUTO mode and the TEMP button adjusted
to 75
F (24
C), give the vehicle about 20 minutes to
stabilize, and adjust your temperature setting if
necessary, by using the TEMP button. The display will
show the temperature setting for a few seconds and then
it will display the outside temperature. If you want to
see your current automatic fan speed, airflow direction
and temperature setting, press the AUTO button.In cold weather, the system will delay turning on the fan,
to avoid blowing cold air. During this delay the system
will be in FRONT defrost mode and the light in the button
will come on and stay on as long as the display is showing
the current mode, set TEMP and FAN speed. This light
will go off when the display returns to the outside
temperature. The length of the delay depends on the
engine coolant temperature and the outside temperature.
Pushing the FAN, AIR FLOW or FRONT buttons will
override this delay, turn off the AUTO setting and return
the system to manual operation.
Personal Choice Comfort Controls
(If Equipped)
This feature enables up to two drivers to store and recall
comfort control settings for the temperature, fan speed
and the direction of the airflow.
The memory buttons (1 or 2) for this feature are located
on the driver's door panel and correspond to the
numbers (1 or 2) found on the back of each keyless
entry transmitter.
To recall comfort settings, press the unlock button on the
remote keyless entry transmitter and put the ignition in
ACCESSORY or RUN. The climate control setting last
chosen by the identified driver (1 or 2) will be recalled.
