In many crashes severe enough to inate an
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage may
also occur from the right front passenger
airbag.
Airbags are designed to inate only once.
After they inate, you will need some new
parts for the airbag system. If you do not get
them, the airbag system will not be there
to help protect you in another crash. A new
system will include airbag modules and
possibly other parts. The service manual for
your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Recording and
Privacy on page 470andEvent Data
Recorders on page 470.
Let only qualied technicians work on your
airbag system. Improper service can mean
that an airbag system will not work properly.
See your dealer/retailer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system.
The passenger airbag status indicator in the
rearview mirror will be visible when you start the
vehicle.
The words ON and OFF, or the symbol for on and
off, will be visible during the system check.

The vehicle may have an automatic dimming
rearview mirror with OnStar®, a compass and map
lamps. Three OnStar®buttons are at the bottom
of the mirror. SeeOnStar®System on page 114
for more information on the services OnStar®
provides.
Mirror Operation
The mirror automatically changes to reduce
glare from headlamps behind you. A time delay
feature prevents rapid changing from the day
to night positions while driving under lights and
through traffic.
P(On/Off):The automatic dimming feature is
activated when the vehicle is started. The automatic
dimming feature is turned on or off by pressing this
button located on the lower part of the mirror. Press
and hold the button for up to three seconds to turn

If the word OFF or the off symbol is lit on the
passenger airbag status indicator, it means that
the passenger sensing system has turned off
the passenger’s airbag(s). SeePassenger Sensing
System on page 59for more on this, including
important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the airbag off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in
the right front passenger seat may not
have the protection of the airbag. See
Airbag Readiness Light on page 191.
Voltmeter Gage
The voltmeter shows
the voltage output
of your battery.
When the engine is
running, it shows
the voltage output of
the charging system.
The reading will change as the rate of charge
changes (with engine speed, for example), but if
the voltmeter reads at 9 volts or below, your
instrument panel cluster and other systems may
shut down. The Driver Information Center (DIC)
will read BATTERY VOLTAGE LOW when
your vehicle is at 10 volts or below. Have it
checked right away. Driving with the voltmeter
reading at 10 volts or below could drain your
battery and disable your vehicle.

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, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might 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 can cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This could also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 319.

CHANGE ENGINE OIL
This message displays when the life of the engine
oil has expired. SeeScheduled Maintenance on
page 433. After an oil change, the engine oil
life system must be reset. See “Engine Oil Life”
underDIC Controls and Displays on page 208.
Also, seeEngine Oil on page 333andEngine Oil
Life System on page 340for more information.
CHECK BRAKE FLUID
This message displays, a chime sounds, and the
brake system warning light on the instrument
panel cluster turns on if the ignition is on to inform
the driver that the brake uid level is low. See
Brake System Warning Light on page 196. Have
the brake system serviced by your dealer as
soon as possible. SeeBrakes on page 361.
CHECK COOLANT LEVEL
This message displays when the engine coolant
level is low. Have the cooling system serviced
by your dealer as soon as possible. SeeEngine
Coolant on page 347.
CHECK GAS CAP
This message displays if the fuel cap has not
been fully tightened. Check the fuel cap to make
sure that it is on properly. Once tightened, it takes
at least one overnight park to reset or clear this
message. If both the CHECK GAS CAP message
and the malfunction indicator lamp in the
instrument panel cluster are on, you may need to
see your dealer for service. SeeMalfunction
Indicator Lamp on page 200for more information.
CHECK OIL LEVEL
This message displays and two chimes sound if
the oil level in the vehicle is low. Once the vehicle
senses a change in the engine oil level, the
light remains off.
If this message appears after starting the engine,
the engine oil level may be too low. You may
need to add oil. SeeEngine Overheating on
page 350.
To acknowledge the message, press the RESET
button. The message reappears every 10 minutes
until this condition changes.

PRESS BRAKE TO START ENGINE
(Automatic Transmission Only)
This message displays if you try to start the
engine by pressing the keyless ignition start button
without having the brake pressed. The brake
needs to be pressed when starting the engine. See
Ignition Positions on page 90for more information.
REDUCED ENGINE POWER
If this message displays and the check engine
light comes on, a noticeable reduction in the
vehicle’s performance may occur. If the REDUCED
ENGINE POWER message is displayed, but
there is no reduction in performance, proceed to
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 your dealer
as soon as possible for diagnosis and repair. See
Malfunction Indicator Lamp on page 200for
more information.Multiple chimes sound when this message is
displayed.
To acknowledge the message, press the RESET
button. The message reappears every ve minutes
until this condition changes.
If the REDUCED ENGINE POWER message is
displayed in combination with the COOLANT
OVER TEMPERATURE message, seeEngine
Overheating on page 350.SERVICE ACTIVE HANDLING SYSTEM
This message displays if there is a problem
with the Active Handling System and your vehicle
needs service. The active handling system
light on the instrument panel cluster also turns on
and a chime sounds. See your dealer. When
this message is displayed, the system is not
working. Adjust your driving accordingly. See
Active Handling System on page 283for more
information.
224

If this occurs, use a gasoline rated at 87 octane or
higher as soon as possible. Otherwise, you might
damage your engine. If you are using gasoline
rated at 87 octane or higher and you hear heavy
knocking, your engine needs service.
If your vehicle has the 7.0L V8 engine
(VIN Code E), use premium unleaded gasoline
with a posted octane rating of 91 or higher.
For best performance, use premium unleaded
gasoline with a posted octane rating of 93.
In an emergency, you can use regular unleaded
gasoline with an octane rating of 87 or higher.
If 87 octane fuel is used, do not perform any
aggressive driving maneuvers such as wide open
throttle applications. You may also hear audible
spark knock during acceleration. Rell your
tank with premium fuel as soon as possible to
avoid damaging your engine. If you are using
gasoline rated at 91 octane or higher and you
hear heavy knocking, your engine needs service.Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT). General Motors recommends against the
use of gasolines containing MMT. SeeAdditives
on page 323for additional information.
California Fuel
If your vehicle is certied to meet California
Emissions Standards, it is designed to operate on
fuels that meet California specications. See the
underhood emission control label. If this fuel is not
available in states adopting California emissions
standards, your vehicle will operate satisfactorily
on fuels meeting federal specications, but
emission control system performance may be
affected. The malfunction indicator lamp may turn
on and your vehicle may fail a smog-check test.
SeeMalfunction Indicator Lamp on page 200.
322

If this occurs, return to your authorized GM dealer
for diagnosis. If it is determined that the condition is
caused by the type of fuel used, repairs may not be
covered by your warranty.
Additives
To provide cleaner air, all gasolines in the
United States are now required to contain additives
that will help prevent engine and fuel system
deposits from forming, allowing your emission
control system to work properly. In most cases,
you should not have to add anything to your
fuel. However, some gasolines contain only the
minimum amount of additive required to meet U.S.
Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves clean,
or if your vehicle experiences problems due to
dirty injectors or valves, look for gasoline that is
advertised as TOP TIER Detergent Gasoline.
Also, your dealer has additives that will help
correct and prevent most deposit-related problems.
Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines
may be available in your area. General Motors
recommends that you use these gasolines if they
comply with the specications described earlier.However, E85 (85% ethanol) and other fuels
containing more than 10% ethanol must no
be used in vehicles that were not designed for
those fuels.
Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in the fuel system and also damage
plastic and rubber parts. That damage would
not be covered under your warranty.
Some gasolines that are not reformulated for
low emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected.
The malfunction indicator lamp may turn on.
If this occurs, return to your dealer for service.
