Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by
your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 356.

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may
be required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount
of cargo being hauled as soon as it is
possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service as
soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 361.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
A loose or missing fuel cap will allow fuel to
evaporate into the atmosphere. A few driving trips
with the cap properly installed should turn the
light off.
191

Service All-Wheel Drive Light
This light should come
on briey when you turn
on the ignition, as a
check to show you it
is working.
The service all-wheel drive light comes on to
indicate that there may be a problem with the drive
system and service is required. Malfunctions
can be indicated by the system before any problem
is apparent, which may prevent serious damage
to the vehicle. This system is also designed
to assist your GM dealer in correctly diagnosing a
malfunction.
Check Gages Warning Light
The check gages light
will come on briey
when you are starting
the engine.
If the light comes on and stays on while you are
driving, check your coolant temperature and
engine oil pressure gages to see if they are in the
warning zones.
Gate Ajar Light
If this light comes on,
the liftgate or liftglass is
not completely shut.
Close the liftgate or liftglass. Never drive with the
liftgate or liftglass even partially open.
196

Fuel Gage
When the ignition is on, the fuel gage tells you
about how much fuel you have remaining.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the gage indicated. For example, the gage may
have indicated the tank was half full, but it
actually took a little more or less than half the
tank’s capacity to ll the tank.
The gage moves a little when you turn a corner
or speed up.
The gage doesn’t go back to empty when you
turn off the ignition.
Low Fuel Warning Light
The light next to the fuel gage will come on briey
when you are starting the engine.
This light comes on when the fuel tank is low on
fuel. To turn it off, add fuel to the fuel tank.
SeeFuel on page 358.
Check Gas Cap Light
If your vehicle has this
light, it will come on if
your gas cap is not
securely fastened.
SeeMalfunction Indicator Lamp on page 190for
more information.

DIC Operation and Displays
The DIC comes on when the ignition is on. After a
short delay the DIC will display the information
that was last displayed before the engine
was turned off.
If a problem is detected, a warning message will
appear on the display. Pressing the trip stem
will acknowledge any warning or service
messages. Pressing any of the DIC steering wheel
buttons — trip information, fuel information,
customization, or select button — will also
acknowledge any warnings or service messages.
You should take any message that appears on
the display seriously and remember that clearing
the message will only make the message
disappear, not correct the problem.
The DIC has different modes which can be
accessed by pressing the four DIC buttons located
on the steering wheel. These buttons are trip
information, fuel information, customization, and
select. The button functions are detailed in
the following pages.

driver’s side tire.
RR TIRE shows the tire pressure for the rear
passenger’s side tire.Timer:The DIC can be used as a timer. Press
the select button while TIMER is displayed to start
the timer. The display will show the amount of
time that has passed since the timer was
last reset, not including time the ignition is off.
Time will continue to be counted as long as
the ignition is on, even if another display is being
shown on the DIC. The timer will record up to
99 hours, 59 minutes and 59 seconds (99:59:59)

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed to correct the
condition. Multiple messages may appear one
after another.Some messages may not require immediate
action. Press any of the DIC buttons on the
steering wheel or the trip odometer reset stem on
the instrument panel cluster to acknowledge
that you received the messages and to clear them
from the display.
Some messages cannot be cleared from the
display because they are more urgent. These
messages require action before they can be
removed from the DIC display. Take any messages
that appear on the display seriously and remember
that clearing the messages will only make the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
CHANGE ENGINE OIL
This message displays when the engine oil needs
to be changed and service is required for your
vehicle. SeeScheduled Maintenance on page 479
andEngine Oil on page 369for more information.
Also seeEngine Oil Life System on page 372

message clears itself after 10 seconds until the
next ignition cycle.

OIL PRESSURE LOW/STOP ENGINE
Notice:If you drive your vehicle while
the engine oil pressure is low, severe engine
damage may occur. If a low oil pressure
warning appears on the Driver Information
Center (DIC), stop the vehicle as soon as
possible. Do not drive the vehicle until the
cause of the low oil pressure is corrected. See
Engine Oil on page 369for more information.
This message displays if low oil pressure levels
occur. Stop the vehicle as soon as safely possible
and do not operate it until the cause of the low oil
pressure has been corrected. Check the oil as soon
as possible and have your vehicle serviced by your
