2009 GMC SIERRA 1500 lock

The recirculation mode cannot be selected in the defog or
defrost mode. When either mode is selected, the system
runs the air conditioning compressor, unless the outside
temperature is close to freezing.
Do not drive the vehicle until all the windows are clear.
:(Outside Air):Press to turn the outside air mode
on. An indicator light comes on to show that outside air is
on. In this mode outside air circulates throughout the
vehicle. The outside air mode can be used with all
modes, but it cannot be used with the recirculation mode.
?(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that
recirculation is on.
This mode recirculates and helps to quickly cool the air
inside the vehicle. It can be used to help prevent outside
air and odors from entering the vehicle.
The recirculation mode cannot be used with oor, defog
or defrost modes. If recirculation is selected with one of
these modes, the indicator light ashes three times and
then turns off. While in recirculation mode the windows
may fog when the weather is cold and damp. To clear the
fog, select either the defog or defrost mode and increase
the fan speed.
The recirculation mode can be turned off by pressing the
outside air button, or by turning off the ignition.
#(Air Conditioning):Press to turn the air conditioning
system on or off. An indicator light comes on to show that
the air conditioning is on. The air conditioning can be
selected in any mode as long as the fan switch is on.
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.
Rear Window Defogger
For vehicles with a rear window defogger, a warming
grid is used to remove fog from the rear window.
<(Rear):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 rear window defogger only works when the ignition
is in ON/RUN. The rear window defogger stays on for
approximately 10 minutes after the button is pressed,
unless the ignition is turned to ACC/ACCESSORY or
LOCK/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.

Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airow. Use the
thumbwheels near the air outlets to open or close off the
airow.
Operation Tips

Clear away any ice, snow, or leaves from air inlets
at the base of the windshield that could block the
ow of air into the vehicle.
Keep the 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 deectors can
adversely affect the performance of the system.
Check with your dealer/retailer before adding
equipment to the outside of the vehicle.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.

This light comes on briey when the ignition key is
turned to ON/RUN. If it does not come on then, have it
xed so it is ready to warn if there is a problem.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If the light comes on while driving, pull off the road and
stop carefully. The pedal might be harder to push or
might go closer to the oor. It can take longer to stop.
If the light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 4-47.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-42.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-66for all

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.
