If the light stays on, turn the ignition to OFF. If the light
comes on 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 light still stays on,
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-39.
The anti-lock brake system warning light should come
on brie y when you turn the ignition key to ON. If
the light does not come on then, have it xed so it will
be ready to warn you if there is a problem.Traction Control System (TCS)
Warning Light
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system.
The TC (traction control) warning light will come on
brie y when you turn the ignition to ON. If it doesn’t
come on then, have it xed so it will be ready to warn
you if there is a problem.
The light will also come on if you turn the traction
control system off using the TC (traction control) on/off
button located near the shift lever.
If the TC (traction control) warning light stays on or
comes on while you are driving, pull off the road as soon
as possible and stop carefully. Try resetting the
system by turning the ignition off then back on. If the
light still stays on or comes back on again while you are
driving, your vehicle needs service. Have the traction
control system inspected as soon as possible. See

Vehicle Information Menu Item
Descriptions
The following paragraphs contain a more detailed
description of each menu item:
OUTSIDE TEMP:If you select this item, the current
outside temperature is displayed at the top of the
screen. It will be in either degrees Fahrenheit (°F) or
degrees Celsius (°C) depending upon whether the
system is set for English or metric units. If you wish to
change the units, seeDIC Main Menu on page 3-55.
MI TRIP A and B (KM TRIP A and B):For information
on the trip odometers, seeTrip Odometers on
page 3-36.
MILES RANGE (KM RANGE):If you select this item,
the approximate number of remaining miles or
kilometers you can drive without refueling is displayed.
This estimate is based on the current driving conditions
and will change if the driving conditions change. For
example, if you are driving in traffic making frequent
stops, the display may read one number, but if you enter
the freeway, the number may change even though
you still have the same amount of gas in the gas tank.
This is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
3-51

If your vehicle is low on fuel, the Fuel Level Low
message will be displayed. See “Fuel Level Low” under
DIC Warnings and Messages on page 3-59for more
information.
MPG AVG (L/100 KM AVG):If you select this item, the
approximate average miles per gallon (mpg) or liters
per 100 kilometers (L/100 km) is displayed. This number
is calculated based on the number of mpg (L/100 km)
recorded since the last time this menu item was reset.
To reset the MPG AVG (L/100 KM AVG), press the CLR
button located to the right of the screen. The display
will return to zero.
MPG INST (L/100 KM INST):If you select this item,
the current fuel economy is displayed. This number
re ects only the fuel economy that the vehicle has right
now and will change frequently as driving conditions
change. Unlike average fuel economy, this menu item
cannot be reset.GAL FUEL USED (L FUEL USED):If you select this
item, the number of gallons or liters of fuel used
since the last reset of this menu item is displayed.
To reset GAL FUEL USED (L FUEL USED), press the
CLR button located to the right of the screen. The
display will return to zero.
AVG MPH (AVG KM/H):If you select this item, the
average speed of the vehicle is displayed in miles per
hour (mph) or kilometers per hour (km/h). This average
is calculated based on the various vehicle speeds
recorded since the last reset of this menu item.
To reset AVG MPH (AVG KM/H), press the CLR button
located to the right of the screen. The display will
return to zero.

normal range, the display will have OK after it.
For example, the display may read 13.2 BATTERY
VOLTS OK.
If there is a problem with the battery charging system,
there are four possible DIC messages that may be
displayed. SeeDIC Warnings and Messages on
page 3-59for more information.ENGINE OIL LIFE:If you select this item, the
percentage of remaining oil life is displayed. If you see
99% ENGINE OIL LIFE on the display, that means
that 99% of the current oil life remains.
When the oil life is depleted, the Change Engine Oil
message will appear on the display. See your GM dealer
for service. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4and
Engine Oil on page 5-16for more information.
When you reset the Change Engine Oil message by
clearing it from the display, you still must reset the
engine oil life system separately. For more information
on resetting the engine oil life system, see “How to
Reset the Engine Oil Life System and the Oil Life
Indicator” underEngine Oil Life System on page 5-19.If
you clear the Change Engine Oil message from the
display, it will not re-appear.
