2008 CHEVROLET UPLANDER climate control

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 3-58.

Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle may have two accessory power outlets.
There may be one outlet located below the climate
controls on the instrument panel and one outlet located
in the rear compartment on the driver’s side.
Pull the cover down to use the accessory power outlet.
When not in use, keep the cover on.
To remove the rear accessory power outlet cover, pull
the tab on the cover and pull it off. To put the cover back
on, line up the tabs at the back of the cover and put
the cover in place. Push down the tab to secure
the cover. When not in use, always cover the rear
accessory power outlet with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
unplug electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating of 20 amperes.Certain electrical accessories may not be compatible with
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 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/retailer before adding
electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
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.

Cigarette Lighter
Your vehicle may have a cigarette lighter. To use the
lighter, located on the instrument panel below the
climate controls, push it in all the way and let go.
When it is ready, it will pop back out by itself.
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 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.
Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
3-24

The air conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
@MAX A/C (Maximum Air Conditioning):Turn the
right knob to this position for maximum air conditioning.
This will select air conditioning and recirculation for
maximum cooling of your vehicle. This mode directs
air to the instrument panel outlets.
Recirculation:This mode keeps outside air from
coming in the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or help heat
or cool the air inside your vehicle more quickly.
This mode will automatically be selected when
you select maximum air conditioning.
((Heated Seats):Press this button to turn on the
heated seats. The button on the left controls the driver’s
seat and the button on the right controls the passenger’s
seat. SeeHeated Seats on page 1-3for additional
information.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity,
or 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 or frost
from your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from the
windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs air to the windshield
and the oor outlets. When you select this mode,
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 directs most of the air to the
windshield and the side window outlets, with some air
directed to the oor outlets. In this mode, the system
will automatically run the air-conditioning compressor,
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.

Rear Window Defogger
If your vehicle has a rear window defogger a warming
grid is used to remove fog from the rear window.
defogger on or off. An indicator light in the button
will come on to let you know that the rear window
defogger is activated.
The rear window defogger will turn 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
pressing the button again or 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 your warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
Dual Climate Control System
Your vehicle may have a dual climate control system.
With this system you can control the heating, cooling,
and ventilation for your vehicle.

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 your 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 your vehicle more
effectively.
Rear Climate Control System
Your vehicle may have a rear climate control system
that lets the driver adjust the fan speed for the rear
seating area. This system works with the main climate
control system.This lever used to adjust the fan speed for the rear seat
passengers is located below the main climate control
system.
A(Fan):Slide the lever to 1, 2, or 3 to increase or
decrease airow to the rear seating area. Slide the fan
knob to 0 to turn the fan off.
AUX (Auxiliary):Slide the lever to AUX to let the
rear passengers adjust the temperature and airow
to the rear seating area.
