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 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.
A high electrical load occurs when several of the
following 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 3-79.
Inadvertent Power Battery Saver
This feature is designed to protect the vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes
if a new car has 15 miles (24 km) or less). 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.

I. Rear Window Defogger
J. Air Delivery Mode
ControlAUTO (Automatic):The system automatically
controls the fan speed, air delivery, air conditioning
and recirculation modes in order to heat or cool the
vehicle to the desired temperature.
To place the system in automatic mode:
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. If the system is set at the warmest
temperature setting, the system will try to
continuously heat the vehicle and will not adjust
the system down as the vehicle warms up.
To avoid blowing cold air in cold weather, the
system delays turning on the fan until warm air
is available. The system starts out blowing air
at the oor, but can automatically change modes
as the vehicle warms up to maintain the chosen
temperature setting. The length of time needed for
warm up depends on the outside temperature and
the length of time that has elapsed since the vehicle
was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
The display can be changed from English to metric units
through the Driver Information Center (DIC). SeeDIC

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The defogger only works when the ignition is on or
during remote start, if programmed. See “Personal
Settings Menu” underVehicle Personalization on
page 2-61for additional information.
=(Rear Window Defogger):Press to turn the rear
window defogger on or off. The rear window defogger
stays on for 10 minutes, before turning off.
If the vehicle’s speed is above 30 mph (48 km/h), the
rear defogger stays on continuously. If turned on again,
the defogger only runs for about ve minutes before
turning off. The defogger can also be turned off by
turning off the engine.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. SeeOutside Heated
Mirrors on page 2-41.
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.

Sensors
The solar sensor located on the instrument panel, near
the windshield, monitors the solar heat.
The interior temperature sensor located on the
instrument panel to the right of the steering wheel,
measures the temperature of the air inside the vehicle.
The climate control system uses the information
from these sensors to adjust the temperature, the fan
speed and the air delivery, in order to maintain the
selected temperature. The system may also supply
cooler air to the side of the vehicle facing the sun.
Do not cover the sensors or the automatic climate
control system will not work properly.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airow.
Turn the thumbwheel towards the vehicle door to open
the outlets and allow the maximum amount of air to
enter your vehicle. Turn the thumbwheel towards
the center console to close the outlets and minimize
the amount of air entering the vehicle.
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 of your vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air
lter may need to be replaced. For more information,
seePassenger Compartment Air Filter on page 3-54.
