Instrument Panel Brightness
D(Instrument Panel Brightness):The knob with
this symbol on it is located next to the exterior lamps
control. Push the knob in all the way until it extends out
and then turn the knob clockwise to brighten or
counterclockwise to dim the lights. Push the knob back
in when nished.
Courtesy Lamps
When a door is opened, the courtesy lamps
automatically come on. They make it easy for you to
enter and leave your vehicle. You can also manually turn
these lamps on by fully turning the instrument panel
brightness control clockwise.
The reading lamps, located on the rearview mirror,
can be turned on or off independent of the automatic
courtesy lamps, when the doors are closed.
Dome Lamp
The dome lamp will come on when you open a door.
You can also turn this lamp on by turning the instrument
panel brightness control clockwise.
Entry Lighting
Your vehicle may have courtesy lamps that will come on
and stay on for a set time whenever the unlock symbol
is pressed on the Remote Keyless Entry (RKE)
Transmitter, if the vehicle has one.
If a door is opened, the lamps stay on while it is open
and then turn off automatically about 25 seconds
after the door is closed. If the unlock symbol is pressed
and you do not open a door, the lamps turn off after
about 20 seconds.
Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps do not turn off at
the end of the delay time. Instead, they slowly dim after
the delay time until they go out. The delay time is
canceled if you turn the ignition key to ON/RUN or
press the power door lock switch. The lamps will dim
right away.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps will not come on unless
a door is opened.
3-17

Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on and off.
Mirror Reading Lamps
Your vehicle has reading lamps on the rearview mirror.
Push the button to turn the reading lamps on and off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up or
down. This is normal. If there is a problem, an alert
will be displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power that
is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as Battery Saver Active or
Service Battery Charging System. If this message is
displayed, it is recommended that the driver reduce the
electrical loads as much as possible. SeeDIC Warnings
and Messages on page 3-52.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):The rear window
defogger turns off automatically after it has been
activated for 10 minutes. It can be turned off manually,
by pressing the button again or by turning the ignition
to the LOCK/OFF position. If additional window clearing
is required, the rear window defogger can be turned
on again for additional window clearing. The length of
defogger operation will increase if the vehicle is
being driven.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed. SeeOutside Power Mirrors on page 2-37.
Do not drive the vehicle until all the windows are clear.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Outlet Adjustment
Use the thumbwheel located below or to the side of
the outlet, to change the direction of the air ow.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside your vehicle more
effectively.
If the airow seems low when the fan is at the
highest setting, the passenger compartment
air lter, if equipped, may need to replaced. For
more information, seePassenger Compartment Air
Filter on page 3-26andScheduled Maintenance
on page 6-4.
If fogging reoccurs while in vent or bi-level modes
with mild temperature throughout the vehicle, turn
on the air conditioner to reduce windshield fogging.
