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. The voltmeter gauge or
the voltage display on the Driver
Information Center (DIC), if equipped,
may show the voltage moving 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 DIC
message might be displayed and it is
recommended that the driver reduce
the electrical loads as much as
possible.
Battery Power Protection
This feature shuts off any interior
lamps if they are left on for more than
10 minutes when the ignition is off.
This will keep the battery from
running down.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is turned
off, if the parking lamps or headlamps
have been manually left on. This
protects against draining the battery.
To restart the 10-minute timer, turn
the exterior lamp control to the
O
position and then back to the;or
2position.
To keep the lamps on for more than
10 minutes, the ignition must be on
or in ACC/ACCESSORY.

also turns the defrost off.
A/C : Touch AC on the climate control
display to turn the automatic air
conditioning on or off. If the fan is turned off or the outside temperature
falls below freezing, the air
conditioner will not run.
Press AUTO to return to automatic
operation and the air conditioner runs
as needed.
Automatic Air Recirculation :
When
the AUTO indicator light is on, the air
is automatically recirculated as
needed to help quickly cool the inside
of the vehicle.
@: Press to alternate between
recirculating air inside the vehicle or
pulling in outside air. The indicator
light on the button is lit when
recirculation mode is active. This
helps to quickly cool the air inside the
vehicle and reduce the entry of
outside air and odors.
Pressing this button cancels automatic
recirculation. Press AUTO to return to
automatic operation; recirculation
runs automatically as needed.
Manual recirculation mode is not
available when in Defrost or some air
distribution modes with air to the
windshield. Auto Defog :
The climate control
system uses a sensor to automatically
detect high humidity inside the
vehicle. When high humidity is
detected, the climate control system
may adjust to outside air supply, turn
on the air conditioner, and direct
more air to the windshield. If the
climate control system does not
detect possible window fogging, it
returns to normal operation. To turn
Auto Defog off or on, see “Climate and
Air Quality” underVehicle
Personalization 0138.
Rear Window Defogger
K:Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.

the mirrors.
Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything else
that is sharp. This may damage the
rear window defogger grid and
affect the radio's ability to pick up
stations clearly. The repairs would
not be covered by the vehicle
warranty.

started remotely. The system uses the
driver’s previous settings to heat or
cool the inside of the vehicle. The rear
defog may come on during remote
start based on cold ambient
conditions. The rear defog indicator
light does not come on during a
remote start. If equipped with heated

sensor information to adjust the
temperature, fan speed, recirculation,
and air delivery mode for best
comfort.
If the sensor is covered, the automatic
climate control system may not work
properly.

Operation Tips
.Clear away any ice, snow, or leaves
from the air inlets at the base of the
windshield that could block the
flow of air into the vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.When you enter a vehicle in cold
weather, press the fan up button to
the maximum fan level before
driving. This helps clear the intake
ducts of snow and moisture, and
reduces the chance of fogging the
inside of the window.
.Keep the air path under the front
seats clear of objects to help
circulate the air inside of the vehicle
more effectively.
.Use of non-GM approved hood
deflectors can adversely affect the
performance of the system. Check
with your dealer before adding
equipment to the outside of the
vehicle.Rear System Air Vents
This vehicle has four round or
rectangular air vents in the headliner
above the second and third row seats.
Press on the center vane rear edge to
open the round outlet. Use the center
vane to rotate the outlet and change
the direction of the airf low. Press on
the center vane leading edge to shut
off the air flow.
Move the slider knob and rotate the
outlet barrel left to right to change the
direction of the air flow and to shut
off the air flow.
Maintenance
Passenger Compartment
Air Filter
The filter reduces the dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance. To
find out what type of filter to use, see
Maintenance Replacement Parts
0452.
