button allows you to scroll through a menu. A blank
page ends each menu.
If a problem is detected, a diagnostic message will appear
on the display. Press RESET to acknowledge any current
warning or service messages. The following pages will
show the messages you can see on the Driver Information
Center (DIC) display by pressing the DIC buttons.
1 FUEL
The FUEL button displays average fuel economy and
instantaneous fuel economy calculated for your specific
driving conditions and range.Press the FUEL button to display average fuel economy,
such as:

AVERAGE 20.1 MPG or

AVERAGE 5.3 L/100 km
The average fuel economy is viewed as a long
-term
approximation of your overall driving conditions. If you
press RESET in this mode while you're driving, the
system will begin figuring fuel economy from that
point in time.

2-98
Miles Since Last Ignition Feature
You can also display number of miles (kilometers)
driven since you last started the vehicle if you press and
hold the RESET button for two seconds, then release.
The miles (or kilometers) since the last ignition cycle
will be set into the trip odometer.
Elapsed Time
Press the TRIP button until ELAP. TIME is displayed,
such as ELAP. TIME 00:00:00.00.
When the ignition is in ON, the Driver Information
Center (DIC) can be used as a stopwatch. The display
can show hours, minutes, seconds and hundredths of
a second. The elapsed time indicator will record up to
99 hours, 59 minutes and 59 seconds, then it will reset
to zero and continue counting. (Hundredths are shown
up to 59 minutes, 59 seconds and 99 hundredths). The
display appears as ELAP. TIME 00:00:00.00 in the
elapsed time function.
You can start or stop the elapsed time by pressing
RESET. To reset the elapsed time to zero, stop the timer
by pressing RESET. Then press and hold RESET until

Press reset in this mode to start calculating the average
speed. Press and hold RESET to clear.
Engine Oil Life
Press the TRIP button until the engine oil life is
displayed, such as OIL LIFE REMAIN 89%.
This is an estimate of the engine oil's remaining useful
life. It will show 99% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the system will alert
you with the message CHANGE OIL SOON.
When the oil life is down to zero, you will receive the
message CHANGE OIL NOW.

2-99
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful
not to reset the OIL LIFE accidentally at any time other
than when the oil has just been changed. It can't be reset
accurately until the next oil change.
To reset the system, see ªHow to Reset the Change Oil
Soon Messageº in the Index.
Also, see ªEngine Oil, When to Changeº and
ªMaintenance Scheduleº in the Index.

SERVICE ABS message is displayed when you are driving,
stop as soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the message stays
on, or comes back on again while you are driving, your

destination. The performance may be reduced the next
time the vehicle is driven.
The vehicle may be driven at a reduced speed while the
REDUCED ENGINE POWER message is displayed,
but acceleration and speed may be reduced. Anytime the
CHECK ENGINE light stays on, the vehicle should be
taken to an authorized Chevrolet dealer as soon as
possible for diagnosis and repair.

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.

low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward the
front of your vehicle. The HUD consists of the
following information:

Speedometer

Turn Signal Indicators

High
-Beam Indicator Symbol

Tachometer

Oil, Temperature and Fuel Gages

Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next higher
gear. The SHIFT light will display at an engine
speed of about 5,750 rpm, just prior to reaching the
engine fuel cut
-off mode. To better understand the

The HUD controls are located to the left of the
steering wheel.To adjust the HUD so you can see it properly:
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
the light conditions in the direction your vehicle is
facing and where you have the HUD dimmer control
set. If you are facing a dark object or a heavily
shaded area, your HUD may anticipate that you are
entering a dark area and may begin to dim.
It is possible for sunlight to enter the HUD causing
all of the graphics to light up. The display will return
to normal when the sunlight is no longer entering
the HUD.
2. Adjust the seat to your driving position. If you
change your seat position later, you may have to
re
-adjust your HUD.
3. Press the DISPLAY switch up or down to center the
HUD image in your view.
The HUD image can only be adjusted up and down,
not side
-to-side.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary. To turn HUD
off, slide the switch to OFF.
