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 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 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 3-51.

Cigarette Lighter
For vehicles with a cigarette lighter, it is located on the
instrument panel below the climate controls. Push
the lighter in all the way and let go. It pops back out
when it is ready to be used.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put ammable items in
the ashtray.

#(Air Conditioning):Press to turn the air
conditioning system on or off. The fan must be on to
operate the air conditioning. An indicator light comes
on when the air conditioning is on.
A slight change in engine performance may be
noticeable when the air conditioning compressor shuts
off and turns on again. This is normal. The system
is designed to make adjustments to help with fuel
economy while still maintaining the selected
temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down so the system
operates more efficiently.
The air conditioning system removes moisture from
the air, so a small amount of water might drip under
the vehicle while idling or after turning off the engine.
This is normal.
Outside Air:Outside air is automatically selected in
any mode, except maximum air conditioning.Rear Window Defogger

remove fog from the rear window.
window defogger on or off. An indicator light comes on
when the rear window defogger is on.
The rear window defogger turns off about 15 minutes
after the button is pressed. If turned on again, the
defogger will only run for about ve minutes before
turning off. The defogger can also be turned off
by turning off the engine.
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.
((Heated Seats):Press to turn on the heated seats.

)(Bi-Level):Air is divided between the instrument
panel and oor outlets. Some air is directed towards the
windshield and side window outlets.
6(Floor):Air is directed to the oor outlets. Use this
mode to send air to the rear of the vehicle. Keep the
area under the front seats free of objects that could
obstruct airow to the rear of the vehicle.
-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield and the oor
outlets. When this mode is selected, the system runs
the air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the defog mode.
0(Defrost):This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield
and the side window outlets, with some air directed to
the oor outlets. In this mode, the system automatically
runs the air-conditioning system, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode.
Do not drive the vehicle until all the windows are clear.
#(Air Conditioning):Press to turn the air
conditioning system on or off. The fan must be on
to operate the air conditioning. An indicator light
comes on when the air conditioning is on.
A slight change in engine performance may be
noticeable when the air conditioning turns off and on
again. This is normal. The system is designed to make

Outlet Adjustment
Use the louvers located on the air outlets to change the
direction of the airow.
Use the thumbwheels on the driver side and passenger
side air outlets to open or close the airow from
these outlets.
Operation Tips

Clear away any ice, snow, or leaves from the air
inlets at the base of the vehicle that could block
the ow of air into the vehicle.
Do not use any non-GM approved hood deectors
that could 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.
