Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned to LOCK and any 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, see ªTwilight Sentinel
žº underExterior Lamps
on page 3-14.

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.
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's dark
outside. Be sure to keep the HUD image dim
and placed low in your ®eld of view.
If your vehicle is equipped with the Head-Up Display
(HUD), 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 a re¯ection in the windshield.
The HUD consists of the following information:
·Speedometer Reading
·Turn Signal Indicators
·High-Beam Headlamp Indicator
·Check Gages Message

Notice:When using an accessory power outlet,
maximum electrical load must not exceed 15 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your battery.
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 some electrical equipment to your
vehicle can damage it or keep other things from
working as they should. This wouldn't be covered by
your warranty. Check with your dealer before
adding electrical equipment, and never use anything
that exceeds the amperage rating.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice:Power outlets are designed for accessory
plugs only. Do not hang any type of accessory
or accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.
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 may be removed for
cleaning. Hold the sides of the ashtray and then pull
the ashtray up and out.
Notice:Don't put papers or other ¯ammable
items into your ashtrays. Hot cigarettes or other
smoking materials could ignite them, causing
a damaging ®re.
To use a 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:Don't hold a cigarette lighter in with your
hand while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
The cigarette lighter will only operate when the ignition
key is in RUN and for 10 minutes after turning the
ignition off. If you would like the lighter to operate
regardless of ignition position, and for extended periods
of time, see ªEngine Compartment Fuse Blockº under
Fuses and Circuit Breakers on page 5-86or see
your dealer.

be ready to warn you if there is a problem.
Battery Warning Light
When you turn the key to
RUN, this light will turn on
brie¯y 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.

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). See
DIC Controls and
Displays on page 3-46.The oil pressure light will come on brie¯y 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 light
comeson 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.
{CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches ®re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
