Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, how much fuel you’re using, and many other things you’ll need to drive safely and economically. The
indicator warning lights and gages are explained on the following pages.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with 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,
transaxle, 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.
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.
3-40

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 possible
If 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 5-8. 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.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misring, hesitation
on acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
3-41

If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to x any
mechanical or electrical problems that may have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection.This can happen if you have recently replaced your
battery or if your battery has run down. The diagnostic
system is designed to evaluate critical emission
control systems during normal driving. This may take
several days of routine driving. If you have done this and
your vehicle still does not pass the inspection for lack
of OBD system readiness, your GM dealer can prepare
the vehicle for inspection.
Oil Pressure Light
If you have low engine oil
pressure, this light will stay
on after you start your
engine, or come on when
you are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it xed immediately by
your GM dealer.
3-42

Highbeam On Light
This light will come on
when the high-beam
headlamps or the
Flash-to-Pass feature
is in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8.
Fuel Gage
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.Your fuel gage tells you about how much fuel you have
left when the ignition is on.
Here are four things some owners ask about. All these
things are normal and do not indicate that anything
is wrong with the 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 reads. For example, the gage read half full,
but it took more (or less) than half of the tank’s
capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate empty when the ignition
is turned off.
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.

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located in
the instrument panel cluster, below the tachometer. The
DIC buttons are located on the center of the instrument
panel, below the center outlets.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display WELCOME DRIVER (1 or 2)
if a personalized key 1 or 2 is used, and then the
information that was last displayed before the engine
was turned off.
The DIC displays the odometer, trip odometers, fuel
economy, trip computer, vehicle system information, and
compass display, if equipped. It also displays warning
messages if a system problem is detected. In addition,
the DIC displays phone numbers that are called
using the OnStar
®system, if equipped. SeeOnStar®
System on page 2-44.If equipped, the outside air temperature automatically
appears in the bottom right corner of the DIC display
when viewing all of the information screens, except for
the oil life screens. If the outside air temperature is
at or below 37°F (3°C), the temperature reading
will toggle between displaying the outside temperature
and the word ICE for two minutes. If there is a problem
with the system that controls the temperature display,
the letters OC (open circuit) or SC (short circuit)
will appear on the display. If this occurs, have the
vehicle serviced by your GM dealer.
The DIC also allows some features to be customized or
personalized, if equipped. SeeDIC Vehicle
Personalization (Uplevel Only) on page 3-68for more
information.
DIC Operation and Displays
The DIC has different modes which can be accessed by
pressing the DIC buttons located on the center of the
instrument panel. The buttons are the information,
set/reset, and menu buttons.
The button functions are detailed in the following pages.
3-45

DIC Buttons
Q4R(Information):Press this button to display the
odometer, trip distance, time elapsed, average speed,
fuel economy, battery voltage, oil life, and to turn off
the DIC.
r(Set/Reset):Press this button to set or reset
certain functions and to turn off or acknowledge
messages on the DIC.
q(Menu):Press this button to display the units,
language, personalization, if equipped, compass zone
and compass calibration, if equipped. SeeDIC

Information Button Items
Q4R
(Information):Press this button to scroll
through the following items:
Odometer
Press the information button until the odometer displays.
This mode shows the distance the vehicle has been
driven in either miles or kilometers.
Trip A and Trip B
Press the information button until A or B displays. This
mode shows the current distance traveled in either
miles or kilometers since the last reset for each
trip odometer. Both trip odometers can be used at the
same time.
The display will show the odometer on the top line and
the trip odometer information, either A or B, on the
bottom line.
Each trip odometer can be reset to zero separately by
pressing the set/reset button while the desired trip
odometer is displayed.
3-46

Fuel Range
Press the information button until FUEL RANGE
displays. This mode shows the approximate number of
remaining miles or kilometers the vehicle can be
driven without refueling.
Fuel range is based on several factors, including
distance travelled, fuel used, fuel capacity, etc. This
estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this mode may read one number, but if the vehicle
is driven on a freeway, the number may change even
though the same amount of fuel is in the fuel tank. This
is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See “LOW
FUEL” underDIC Warnings and Messages on
page 3-51for more information.
Average Fuel Economy
Press the information button until AVG ECONOMY
displays. This mode shows the approximate average
miles per gallon (mpg) or liters per 100 kilometers
(L/100 km). 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 AVG ECONOMY,
press and hold the set/reset button. The display
will return to zero.
Instantaneous Fuel Economy
Press the information button until INST ECONOMY
displays. This mode shows the current fuel economy at
a particular moment and will change frequently as
driving conditions change. This mode shows the
instantaneous fuel economy in miles per gallon (mpg) or
liters per 100 kilometers (L/100 km). Unlike average
fuel economy, this screen cannot be reset.
Battery
Press the information button until BATTERY displays.
This mode shows the current battery voltage.
If there is a problem with the battery charging system, a
DIC message will display. SeeDIC Warnings and
Messages on page 3-51for more information.

LOW BRAKE FLUID
This message will display when the brake uid level is
low. Fill the brake master cylinder to the proper
level. SeeEngine Compartment Overview on page 5-12
for the location of the brake master cylinder reservoir.
Also, seeBrakes on page 5-36for proper uid level.
The brake system warning light will also appear on the
instrument panel cluster when this message appears
on the DIC. SeeBrake System Warning Light on
page 3-37.
This message will display and a chime will sound only
while the ignition is in RUN. Press any of the DIC
buttons to acknowledge this message and to clear it
from the screen.
This message will continue to display for two seconds if
it has not been acknowledged when the engine is
turned off. It will also re-display for two seconds if the
message has been acknowledged, but the condition still
exists when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on.
LOW FUEL
This message will display when your vehicle is low on
fuel. You should rell the tank as soon as possible. See
Fuel Gage on page 3-44andFilling the Tank on
page 5-8for more information.The message will display and a chime will sound while
the ignition is in RUN. Press any of the DIC buttons
to acknowledge this message and to clear it from
the screen.
If the condition still exists, the message will re-appear
when the engine is turned on.
LOW OIL PRESSURE
Notice:If the LOW OIL PRESSURE warning
message appears on the DIC display, stop the
vehicle immediately. Do not drive the vehicle until
the cause of the low oil pressure is corrected.
Severe engine damage can result from driving a
vehicle with low oil pressure. SeeEngine Oil
on page 5-13for more information.
This message will display when the vehicle’s engine oil
pressure is low. The oil pressure light will also appear
on the instrument panel cluster. SeeOil Pressure Light
on page 3-42.
Stop the vehicle immediately, as engine damage can
result from driving a vehicle with low oil pressure. Have
the vehicle serviced by your GM dealer as soon as
possible when this message is displayed.
This message will display only when the ignition is in
RUN. A chime will sound continuously when this
message is displayed.

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to
move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are
going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will nd experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?
