Entry LightingFor vehicles with courtesy lamps, they 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 20 seconds
after the door is closed. If the unlock symbol is pressed
and no door is opened, 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 and
then go out. The delay time is canceled if the ignition
key is turned to ON/RUN or the power door lock switch
is pressed. 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.
Delayed Entry LightingDelayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature continues to
work until one of the following occurs:•
The ignition is in ON/RUN.
•
The doors are locked.
•
An illumination period of about 25 seconds has
elapsed.
If during the illumination period a door is opened, the
timed illumination period is canceled and the interior
lamps remain on.
4-12

Delayed Exit LightingThis feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to work.
When the key is removed, interior illumination activates
and remains on until one of the following occurs:•
The ignition is in ON/RUN.
•
The power door locks are activated.
•
An illumination period of 20 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Parade DimmingParade mode automatically prohibits the dimming of
the instrument panel displays during the daylight while
the headlamps are on so that the displays are still
able to be seen.Reading LampsThe vehicle has reading lamps that also act as the
dome lamp. Press the button near each lamp to turn
them on and off.
Map LampsThe vehicle has map lamps on the rearview mirror.
Press the button near each lamp on the mirror to turn
the map lamps on and off.Electric Power ManagementThe 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 bring the charge back up. 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.

increase or decrease the fan speed. Positioning the knob
between two modes, can select a combination of those
modes.
If the airflow seems low when the fan is at the highest
setting, the passenger compartment air filter may need to
be replaced. There will be some airflow noticeable from
the various outlets when driving, even with the fan in
the off position. For more information, seePassenger
Compartment Air Filter on page 4-20andScheduled

Using these settings together for long periods of time
may cause the air inside the vehicle to become too dry.
To prevent this from happening, after the air inside
the vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so a small amount of water may drip under
the vehicle while idling or after turning off the engine.
This is normal.:
(Outside Air):Press to turn on outside air.
An indicator light comes on to show that it is on.
Outside air will circulate throughout the vehicle.
?
(Recirculation):Press to turn on the recirculation
mode. An indicator light comes on to show that
it is on.
This mode helps to quickly heat or cool the air inside the
vehicle once the temperature inside the vehicle is equal
to or better than the outside temperature. It can be used
to prevent outside air and odors from entering the vehicle.
The recirculation mode is not available in outside air,
floor, defog or defrost modes. If the button is selected
while in these modes, the indicator flashes three times.
Rear Window DefoggerThe 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. 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.
For vehicles with heated outside rearview mirrors, the
mirrors 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 3-34.
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 the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.

Outlet AdjustmentUse the thumbwheel located below or to the side of the
outlet, to change the direction of the air flow.Operation Tips•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into the vehicle.
•
Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•
Keep the path under the front seats clear of objects
to help circulate the air inside the vehicle more
effectively.
•
If the airflow seems low when the fan is at the
highest setting, the passenger compartment
air filter, if equipped, may need to replaced.
For more information, seePassenger Compartment
Air Filter on page 4-20andScheduled Maintenance

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.
Passenger Compartment Air FilterThe vehicle has a passenger compartment particulate
air filter. It is located in the engine compartment,
below the air inlet grille on the passenger side.
The filter traps most of the pollen from air entering
the climate control system. It needs to be changed
periodically to ensure system performance. For
information on how often to change the passenger
compartment air filter, seeScheduled Maintenance
on page 7-3.
To change the passenger compartment air filter:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the vehicle hood.
3. Pull back the hood weatherstrip from the
passengers side of the vehicle halfway to center.
