Light Sensor
Your Twilight
Sentinel®and DRL work
with the light sensor
located on top of the
instrument panel.
Do not cover it up. If you do, it will sense darkness and
the Twilight Sentinel
®lighting will turn on.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition
is turned to LOCK and a door has been opened.
This protects against draining the battery in case you
have accidentally left the headlamps or parking
lamps on. If you need to leave the lamps on for more
than 10 minutes, use the manual control to turn the
lamps back on after the ignition is turned to LOCK and
any door is opened. To delay the lamps from turning
off, seeTwilight Sentinel
®on page 3-16.
Instrument Panel Brightness
The lever for this feature is
located to the left of the
steering column.
The brightness of the instrument panel lights can be
adjusted by sliding the INTERIOR lever from LO to HI.
The instrument panel lights will be on only while the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the
way to HI.
Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. You can also turn these lamps
on by sliding the INTERIOR lever all the way to HI.
3-17

Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher RPM setting than normal to make sure the
battery charges. High electrical loads may occur when
several of the following are on: headlamps, high beams,
rear window defogger, fan at high speed, heated
seats (if equipped) and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, or garage
door opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes. Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened or
the courtesy lamp switch is turned on.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If your vehicle has the Head-Up Display (HUD) feature,
you can see some of the driver information that
appears on your instrument panel cluster.
The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. The HUD consists of the
following information:
Speedometer Reading
Turn Signal Indicators
High-Beam Headlamp Indicator
Check Gages Message
3-20

Your vehicle may have a small cap that must be pulled
down to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it with
the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible to
the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem
see your dealer for additional information on the
accessory power outlets.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Check with your
dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.Ashtrays and Cigarette Lighter
Pull down the front center tray to reveal the front
ashtray, cigarette lighter and accessory power outlet.
The front center and rear ashtrays can be removed for
cleaning. Hold the sides of the ashtray and then pull
the ashtray up and out.
Notice:If you put papers or other ammable
items in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put ammable items in
the ashtray.
To use the lighter, push the center all the way in and let
it go. When it is ready, the center will pop back out
by itself. Pull out the entire unit to use it.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating. Do not
use anything other than the cigarette lighter in the
heating element.

Battery Warning Light
When you turn the key to
RUN, this light will turn on
briey to show that the
generator and battery
charging systems
are working.
If the light stays on, a chime will sound indicating that
the vehicle needs service. You should take your vehicle
to the dealer as soon as possible. To save the battery
until you get there, turn off all accessories and set
the climate control system to OFF.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can still
work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on when you turn the key to
RUN. If it doesn’t come on then, have it xed so it will
be ready to warn you if there’s a problem.

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 in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON 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 your vehicle has the
standard instrument panel
cluster, this light will
come on if there is a
problem with your vehicle’s
engine oil pressure.
If your vehicle has the optional gage cluster, you can
read your oil pressure directly from the Driver
Information Center (DIC). SeeDIC Controls and
Displays on page 3-47.
The oil pressure light will come on briey when you turn
your key to RUN. That’s just a check to be sure the
light works. This is normal and doesn’t show a problem.
If it doesn’t come on and then go off, be sure to have
it xed so it will be there to warn you if there is
a problem.
When this lightcomeson andstayson, and a chime
sounds, it means oil isn’t going through the engine
properly. The oil could be low, or there might be some
other oil problem. See your dealer for service.

see the COOLANT TEMP HOT message, the engine
is overheated. You should pull off the road, stop
your vehicle and turn off your engine as soon as
possible. This manual explains what to do. SeeEngine
Overheating on page 5-26.
Press the GAGE INFO button until the display shows
BATTERY STATE. If the voltage is normal the display
will show BATTERY STATE NORMAL. If the voltage
drops below 10.5 volts, the display will show BATTERY
STATE LOW. If the voltage is above 16.2 volts, the
display will show BATTERY STATE HIGH. If the displayshows the high or low message, you need to have your
battery and charging system checked. See your
GM dealer.
Press the GAGE INFO button until OIL LIFE INDEX
appears in the display. The OIL LIFE INDEX NORMAL
display will show an estimate of the oil’s remaining
useful life. When the oil life index is less than 10 percent,
the display will show OIL LIFE INDEX CHANGE OIL.
This means service is required for your vehicle.
See your GM dealer.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. See
Part A: Scheduled Maintenance Services on page 6-4
andEngine Oil on page 5-13for more information.
When you have the oil changed according to the
maintenance schedule, you will have to reset the engine
oil life system. To reset the engine oil life system, see
“How to Reset the Engine Oil Life System” underEngine
Oil Life System on page 5-17.
Press the GAGE INFO button until TIRE PRESSURE
appears in the display. TIRE PRESSURE NORMAL
