Functions
(Door Ajar): If one of the doors is ajar, this
light will appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the
system indicates that it's time for an oil change. The
system predicts remaining oil life using data from length
of drives, coolant temperature, engine rpm and vehicle
speed. It alerts you to change the oil on a schedule
consistent with the vehicle's driving conditions. After
changing the oil, the system must be reset. See ªHow to
Reset the GM Oil Life System
º in the Index.
LOW: This light will come on when the ignition is
on and the fluid in the washer fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.LOW TRAC (Low Traction): This light will come on
when the enhanced traction system is limiting wheel
spin. See ªEnhanced Traction Systemº or ªLow Traction
Lightº in the Index.
TRAC OFF (Traction Off): This light lets you know
that the enhanced traction system has been disabled and
will not limit wheel spin. See ªEnhanced Traction
System Warning Lightº or ªLow Traction Lightº in
the Index.
TRAC (Traction): If the vehicle has the enhanced
traction system, you will have a disable button on the far
right side of the DIC. The enhanced traction system is
automatically activated when you turn the ignition on.
This button will activate/deactivate the system. If you
need to disable the system, such as when you are stuck
and are rocking the vehicle back and forth, push this
button. See ªStuck: In Sand, Mud, Ice or Snowº in
the Index.

since you last reset this mode. The amount can be
displayed in gallons or liters.
AVG ECON (Average Economy): Shows the average
fuel economy since you last reset this mode.
OIL LIFE: Shows a percentage of the oil's remaining
useful life. The system predicts remaining oil life using
data from length of drives, coolant temperature, engine
rpm and vehicle speed. Each time you get an oil change,
be sure to reset this function so that it will give you an
accurate percentage. See ªHow to Reset the GM Oil Life
System
º in the Index.RANGE: Shows how much farther you can travel with
the fuel you have remaining in the gas tank before
refueling. When the range displays L, for 40 to 50 miles
(64.36 to 80.45 km), the display will flash LOW
continuously. The range is calculated from the AVG
ECON value multiplied by the fuel remaining in
the tank.
LOW: This light will come on the vehicle outline when
the ignition is on and the fluid in the washer fluid
container is low.
DOOR AJAR: If one of the doors is left ajar, a light
will appear next to that door on the vehicle outline.

ªEnhanced Traction System Warning Lightº and ªLow
Traction Lightº in the Index.
TRAC (Traction) or TCS (Traction Control System):
If the vehicle has the enhanced traction system (3100 or
3800 V6 engine) or the traction control system
(3800 supercharged V6 engine), you will have a disable
button on the far right side of the trip computer. The
enhanced traction system and traction control system are
automatically activated when you turn the ignition on.
This button will activate/deactivate the system. If you
need to disable the system, such as when you are stuck
and are rocking the vehicle back and forth, push this
button. See ªStuck: In Sand, Mud, Ice or Snowº in
the Index.Head-Up Display (HUD) (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the Head-Up
Display (HUD), you can
see the speedometer reading
(in English or metric units)
and a brief display of the
current radio station or CD
track, displayed ªthroughº
the windshield.

2-97
When you sit up straight in your seat, the HUD image
will appear straight ahead near the front bumper.
The HUD also shows the following lights when they are
lit on the instrument panel cluster:

Turn Signal Indicators

High
-Beam Indicator Symbol

Low Fuel Symbol
The HUD will display CHECK GAGES when the
following items are lit on the instrument panel cluster:

Oil Warning Symbol

Coolant Temperature Symbol

Charging System Symbol
When the ignition key is turned to RUN, the entire HUD
image will come on. Then the Head
-Up Display will
operate normally.
NOTICE:
Although the HUD image appears to be near
the front of the vehicle, do not use it as a parking
aid. The HUD was not designed for that purpose.
If you try to use it that way, such as in a parking
lot, you may misjudge distance and run
into something.
When the HUD is on, the speedometer reading will be
displayed continually. The current radio station or CD
track number will only be displayed for three seconds
after the radio or CD track status changes. This will
happen whenever one of the radio controls is pressed,
either on the radio itself or on the optional steering
wheel controls.

3-3
(Vent): This setting brings in outside air and directs
it through the instrument panel outlets.
(Bi-Level): This setting brings in outside air and
directs it two ways. Half of the air is directed through
the vent outlets. Most of the remaining air is directed
through the floor ducts and a small amount to the defrost
and side window vents.
(Floor): This setting sends most of the air through
the ducts near the floor. The remaining airflow comes
out of the defroster and side window vents.
(Defogger): This setting allows half of the air to
go to the floor ducts and half to the defroster and side
window vents.
FRONT (Defroster): This setting directs most of
the air through the defroster. Some of the air goes to the
floor ducts and the side window vent. The air conditioning
compressor will run automatically in this setting unless the
outside temperature is below 38
F (3.3
C).
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioning
compressor. The indicator light above the button will
glow when the button is pressed. You don't have topress the button to run the compressor in MAX
or defrost because it will already be running in
these modes.
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time it takes for
the vehicle to cool down.
For quick cool down on very hot days, turn the fan on
and use MAX with 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 fan on and use
vent with the temperature levers in the blue area and the
A/C button pressed in. 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. To
remedy this, you can use bi
-level with the temperature
levers in the middle and the A/C button pushed in. The
system will bring in outside air and direct it to your
upper body, while sending slightly warmed air to your
lower body.

3-4
Heating
On cold days select a fan setting and use floor with 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.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside 0
F (
-18
C) or lower. An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Ventilation
For mild outside temperatures when little heating
or cooling is needed, use a fan setting and vent with
the A/C button off, to direct outside air through
your vehicle.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, turn the
fan to a high setting and use defroster with the
temperature levers all the way in the red area. To
warm passengers while keeping the windows clear,
use defogger.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The comfort control
system has a button to
operate your vehicle's
rear window defogger.
It is marked REAR.
Press the button to turn the rear window defogger on or
off. When the rear window defogger is operating, an
indicator above this button will light. The rear warming
grid will turn off after about 15 minutes.
If you turn the rear window defogger on again, it will
operate for about seven and one half minutes before
turning off. The system will turn off when the ignition is
turned off.
Do not attach anything like a temporary vehicle license
or decal across the rear window defogger grid.

Your tape player is built to work best with tapes that
are up to 30 to 45 minutes long on each side. Tapes
longer than that are so thin they may not work well in
this player.
While the tape is playing, use the VOL, FADE, BAL,
BASS and TREBLE controls just as you do for the
radio. The display will show an arrow to show which
side of the tape is playing. When the down indicator
arrow is lit, selections listed on the bottom side of the
cassette are playing. When the up arrow is lit, selections
listed on the top side of the cassette are playing. The
tape player automatically begins playing the other side
when it reaches the end of the tape.
If an error appears on the display, see ªCassette Tape
Messagesº later in this section.
