Hazard Warning Flashers
Your hazard warning ashers let you warn others. They
also let police know you have a problem. Your front

Exterior Lamps
The control on the driver’s side of your instrument panel
operates the exterior lamps.
The exterior lamp control has four positions:
9(Off):Turn the knob to this position and release it
to turn off all exterior lamps including the DRLs. To turn
any lamps back on when in the off mode, turn the
knob to the desired lamp mode. To return to the AUTO
mode, turn the knob to the off position and release
it. The off mode will also cancel and the lamps will return
to the AUTO when the vehicle is turned off. This
mode is not available for vehicles rst sold in Canada.AUTO:Turn the control to this position to put the
system into automatic headlamp mode. The Daytime
Running Lamps (DRL) will also be activated if it is light
enough outside.
;(Parking Lamps):Turn the control to this position
to turn on the parking lamps, together with the
following:
Parking Lamps
Sidemarker Lamps
Taillamps
License Plate Lamps
Roof Marker Lamps
Instrument Panel Lights
2(Headlamps):Turn the control to this position to
turn on the headlamps, together with the previously
listed lamps and lights.
When the vehicle is turned off and the headlamps are in
AUTO, the headlamps may automatically remain on
for a set time. You can change this delay time using the
DIC. SeeDriver Information Center (DIC) on page 3-44.
You can switch your headlamps from low to high-beam
by pushing the turn signal/multifunction lever toward
the instrument panel.
3-13

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a personal trip
and business trip odometer. See “Trip Information” under
DIC Operation and Displays on page 3-44.
The odometer mileage can be checked without the
vehicle running. Simply press the trip stem on the
instrument panel cluster.
If your vehicle ever needs a new odometer installed, the
new one will be set to the correct mileage total of the
old odometer.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will ash for several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeAir Bag System on page 1-61.
3-28

Transmission Temperature Gage
Your vehicle is equipped with a transmission
temperature gage.When your ignition is on, the gage shows the
temperature of the transmission uid. The normal
operating range is from 100°F (38°C) to about
265°F (130°C).
At approximately 265°F (130°C), the DIC will display a
TRANSMISSION HOT message and the transmission
will enter a transmission protection mode. When
the transmission enters the protection mode, you may
notice a change in the transmission shifting patterns.
The transmission will return to normal shifting patterns
when the transmission uid temperature falls below
260°F (127°C).
SeeDriver Information Center (DIC) on page 3-44for
further information. United States

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.
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.
