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, such as: 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,
BATTERY VOLTAGE LOW, or LOW BATTERY. 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 3-56.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, or garage door
opener. When the ignition is turned off, the power to
these features will automatically turn off after 10 minutes.
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.

Automatic Operation
AUTO (Automatic Fan):When AUTO is selected on
the fan control, the system automatically adjusts the fan
speed. If the OnStar
®system is activated when this
position is selected, the fan speed will lower.
AUTO (Automatic Mode)
1. Turn the fan control to AUTO.
2. Turn the mode control to AUTO.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
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 system will start
out blowing air to the oor, but may change 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.
4. Wait a few minutes for the system to automatically
regulate. Then adjust the temperature as necessary
to nd your comfort setting.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
After the vehicle is started, the display shows the
interior temperature settings.
3-25
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
shows readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between the readings.
AUTO (Automatic Air Conditioning):If AUTO
is selected on the fan or mode control, the system
automatically controls the air conditioning compressor.
The A/C compressor runs automatically even at cool
outside temperatures in order to dehumidify the air.
The A/C indicator light is lit when the system is operating
automatically. Press the A/C button on the fan control
to turn off the A/C. To clear windows better in defog or
defrost modes, the A/C compressor runs automatically
in damp cool conditions.
h(Auto Recirculation):If AUTO is selected on
either the fan or mode control, the system automatically
controls the supply of fresh outside air or recirculates the
interior air to cool the car faster. The indicator light on
the recirculation button will light whenever the system
switches to recirculation. You may force outside air by
pressing the outside air button. The next time AUTO fan
or mode is selected, it will reset back to AUTO operation.
Manual Operation
9(Off):Turns the climate control system off. Outside
air still enters the vehicle and is directed to the oor.
The air ow direction and temperature can be adjusted.
If the temperature is adjusted while the system is
off, the display will light to show the current settings.
wx(Driver Temperature Controls):Press
these buttons next to the fan control to increase
or decrease the temperature inside the vehicle.
wx(Passenger Temperature Controls):Press
these buttons next to the mode control to increase
or decrease the temperature for the front passenger.
If the passenger climate control system is off, pressing
one of these buttons turns it on.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. Turning this
control completely counterclockwise turns on the
automatic fan operation.
If the air ow 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 3-30
andScheduled Maintenance on page 6-4.
3-26
?(Recirculation):Press to turn the recirculation
mode on. An indicator light below the button comes on to
show that this mode is on. This mode recirculates and
helps to quickly cool the air inside the vehicle. It can be
used to prevent outside air and odors from entering the
vehicle. This mode cannot be selected while in the defog
or defrost modes. If you try to select the recirculation
mode, the indicator light ashes three times and turns off.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode.
PASS (Passenger Climate Control):Press to turn the
passenger climate control systems on or off.
When the passenger climate control system is on, the
passenger temperature setting is displayed.
If the PASS button is pressed to turn the passenger
temperature setting off, the driver temperature setting
controls the temperature for the entire vehicle.Sensors
The solar sensor, located in the defrost grille, in the
middle of the instrument panel, monitors the solar
radiation. Do not cover the solar sensor or the system
will not work properly.
3-28
There is also an interior temperature sensor located
next to the steering wheel that measures the
temperature of the air inside the vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false temperature reading to display.
In order to prevent false temperature readings at
startup, the displayed temperature will not change
until the following occurs:
Vehicle speed is above 10 mph (16 km/h) for
ve minutes.
Vehicle speed is above 32 mph (51 km/h) for
two and a half minutes.
The climate control system uses the information
from these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the air
delivery mode. The system may also 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.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press to turn the rear window
defogger on or off. An indicator light below the button
comes on to show that the rear window defogger is on.
Be sure to clear as much snow from the rear window
as possible.
The rear window defogger only works when the ignition
is in ON/RUN. The rear window defogger stays on
for about 20 minutes after the button is pressed if the
vehicle is traveling at slower vehicle speeds. At higher
vehicle speeds the rear window defogger may stay on
continuously. If turned on again, the defogger only runs
for about 10 minutes before turning off. The defogger can
be turned off by pressing the button again, by turning the
ignition to ACC/ACCESSORY or ON/RUN, or by turning
off the engine.
The heated outside rearview mirrors will 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 2-37for more information.
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.

Speedometer and Odometer
The speedometer shows the vehicle speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven, in either miles or kilometers.
This vehicle has a tamper resistant odometer.
If the vehicle needs a new odometer installed, the new
one can be set to the mileage total of the old odometer.
If this is not possible, it is set to zero and a label must be
put on the driver’s door to show the old mileage reading
when the new odometer was installed.
Trip Odometer
A trip odometer show how far the vehicle has been
driven since the odometer was last set to zero.
SeeDriver Information Center (DIC) on page 3-49
for information on resetting the trip odometer.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
3-34
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located
below the speedometer in the instrument panel cluster.
The DIC buttons are located on the instrument panel,
to the left of the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was last
displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. The bottom line of the DIC shows the shift
lever position indicator. SeeAutomatic Transmission
Operation on page 2-25for more information.
If your vehicle’s DIC has these features, the compass
direction and the outside air temperature may also
display on the DIC when viewing the trip and fuel
information. The compass direction appears on the
top right corner of the DIC display. The outside air
temperature automatically appears in the bottom right
corner of the DIC display. If there is a problem with
the system that controls the temperature display,
the numbers will be replaced with dashes. If this occurs,
have the vehicle serviced by your dealer/retailer.
The DIC also allows some features to be customized.

(Trip/Fuel):Press this button to scroll through the
following menu items:
Odometer
Press the trip/fuel button until ODOMETER displays.
This display shows the distance the vehicle has
been driven in either miles (mi) or kilometers (km).
Trip A and Trip B
Press the trip/fuel button until TRIP A or TRIP B
displays. This display shows the current distance traveled
in either miles (mi) or kilometers (km) since the last reset
for each trip odometer. Both trip odometers can be used
at the same time.Each trip odometer can be reset to zero separately by
pressing the set/reset button while the desired trip
odometer is displayed.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles (kilometers) driven since the ignition was
last turned on. This can be used if the trip odometer is not
reset at the beginning of the trip.
To use the retro-active reset feature, press and
hold the set/reset button for at least four seconds.
The trip odometer will display the number of miles (mi)
or kilometers (km) driven since the ignition was last
turned on and the vehicle was moving. Once the vehicle
begins moving, the trip odometer will accumulate
mileage. For example, if the vehicle was driven 5 miles
(8 km) before it is started again, and then the retro-active
reset feature is activated, the display will show 5 miles
(8 km). As the vehicle begins moving, the display will then
increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the display
will show the number of miles (mi) or kilometers (km) that
were driven during the last ignition cycle.
