Hazard Warning Flashers
The hazard warning ashers let you warn the
police and others that you have a problem. The
front and rear turn signal lamps will ash on
and off.
The hazard warning
asher button is located
on the instrument
panel below the climate
control system.
The hazard warning ashers work no matter what
position the key is in, and even if the key is not
in the ignition switch.
Press the button to make the front and rear turn
signal lamps ash on and off. Press the button
again to turn the ashers off.
While the hazard warning ashers are on, the turn
signals do not work.
Other Warning Devices

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 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 220.

Certain accessory power plugs may not be
compatible to the accessory power outlet 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. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
Follow the proper installation instructions that are
included with any electrical equipment you
install.
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.Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and cigarette
lighter.
Notice:If you put papers, pins, 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.
Ashtray
The ashtray is located under the climate control
panel on the instrument panel. Press on the
door to release the ashtray.

Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, defrosting, and ventilation for the vehicle.
Automatic Operation
The climate control system automatically adjusts
the air temperature, air delivery mode, fan
speed, and air conditioning for best comfort in the
vehicle.To activate the automatic system:
AUTO (Automatic Mode):
1. Turn the fan and mode controls to the AUTO
position. This also sets the recirculation mode
to automatic operation on the display.
2. Press the up or down arrows to adjust the
temperature to a comfortable setting between
70°F (21°C) and 80°F (27°C).
3. Allow the system time to stabilize. This might
take several minutes in very hot or cold
weather. Then adjust the temperature, as
needed for best comfort.
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available.
The automatic system starts out blowing air at
the oor, but changes modes automatically as
the vehicle warms up to maintain the chosen
temperature setting.
The length of time needed to warm the interior
depends on the outside temperature and
the amount of time that has passed since the
vehicle was last driven.

«ª(Driver’s Temperature Controls):Press
the up or down buttons closest to the driver
to manually increase or decrease the temperature
inside the vehicle.
«ª(Passenger’s Temperature Controls):
Press the up or down buttons closest to the
passenger to manually increase or decrease the
temperature for the front passenger. If the
passenger’s climate control system is off, pressing
either of these buttons turns it on.
Manual Operation
9(Fan):Turn the left control to adjust the fan
speed manually if the automatic setting is higher or
lower than desired. The fan speed remains at
this level until you return to AUTO or adjust to a
different level. In the automatic position, the blower
might go to a lower speed during an OnStar
®
session to limit the background noise.To change the current mode, select one of the
following positions using the right control:
AUTO:Turn the control to this position to turn on
the automatic delivery mode operation.
F(Vent):Turn the control to this position so that
air is directed to the instrument panel outlets.
*(Bi-Level):Turn the control to this position so
that half of the air is directed to the instrument
panel outlets and the other half goes to the oor
outlets. The temperature of the air to the oor
will be warmer than the air to the upper outlets.
7(Floor):Turn the control to this position so that
most of the air is directed to the oor outlets
with some air directed to the outboard outlets, side
window outlets, and defroster outlet.
W(Defog):Turn the control to this position so
that air is directed between the windshield
and oor outlets, with some air going to the
outboard outlets and side window outlets. More
information of defogging can be found later in this
section.
190

0(Defrost):Turn the control to this position so
that most of the air is directed to the windshield
with some air going to the side window outlets.
More information on defrosting can be found later
in this section.
O(On/Off):Press this button to turn the climate
control system on or off. While off, adjusting
any button or control, except recirculation and rear
window defog turns the system back on. The air
inlets default to outside air when the climate
control system is turned off.
PASS (Passenger’s Climate Control):Press this
button to turn the passenger’s climate control
system on or off. Then press the up or down
buttons to choose the desired setting. Pressing
the button again automatically sets the passengers
temperature to the drivers setting. Turning the
passenger’s temperature display off does not turn
off the climate control system for the passenger.
Recirculation Operation
There are three options for bringing air into the
climate control system. They are controlled
by pressing the center button on the climate
control panel. The climate control display indicates
one of the following three modes:
9AUTO (Auto Air Inlet):This mode lets the
automatic climate control system choose the
best air inlet position for cooling or warming the
vehicle. To have full automatic climate control,
the fan and mode controls must be set to
the AUTO position. Generally, recirculation will
only automatically be selected on hot days.
Your vehicle may have an optional Air Quality
Sensor. To activate the air quality sensor, the
auto air inlet setting must be used. For more
information, see Air Quality Sensor found later
in this section.
191

There is also an interior temperature sensor
located below the climate control system next to
the steering wheel.
There is also an ambient sensor located behind
the grille in front of the vehicle.
These sensors help the climate control system
automatically control the temperature setting. The
system can supply cooler air to the side of the
vehicle facing the sun. The recirculation mode will
also be used as needed to maintain cool outlet
temperatures.
Do not cover any of the sensors or the climate
control system might not work properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog from the windshield.
W(Floor/Defog):Use this mode to clear the
windows of fog and warm the passengers.
The system turns off recirculation and runs the air
conditioning compressor unless the outside
temperature is at or below freezing. If recirculation
mode is selected while using the defog mode,
the system recirculates air initially but returns to
the fresh air mode after 10 minutes.
0(Defrost):Use this mode to remove fog or
frost from the windshield more quickly. When
selected, the system turns off recirculation
and runs the air conditioning compressor, unless
the outside temperature is at or below freezing.
Do not drive the vehicle until all the windows are
clear.
193

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press the center of the
right control to turn the rear window defogger on or
off. Be sure to clear as much snow from the
rear window as possible. The rear window
defogger turns off about 20 minutes after the
button is rst pressed if the vehicle is moving at
slower speeds. At higher vehicle speeds, the rear
defogger can stay on continuously. Each
additional press runs the defogger for about
10 minutes.
The heated outside rearview mirrors also heat to
help clear fog or frost from the surface of the
mirror when the rear window defogger is on.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the knobs located in the center of each outlet
to change the direction of the airow. Use the
thumbwheels to open or close the outlets.
Operation Tips

Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that
could block the ow of air into the 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 of the
vehicle more effectively.
If the airow seems low when the fan speed is
at the highest setting, the passenger
compartment air lter might need to be
replaced. For more information, see
Passenger Compartment Air Filter on
page 195.
Set the climate control system to AUTO fan
and mode and then adjust the temperature
setting up or down a few degrees for
best comfort.
