2009 CHEVROLET AVALANCHE light

When the headlamps are turned on while the vehicle is
on, the headlamps turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will
stay on for 10 minutes before automatically turning off to
prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp
on position to make the headlamps stay on for an
additional 10 minutes.
Push the turn signal/multifunction lever toward the
instrument panel to change the headlamps from low
beam to high beam.
Headlamps on Reminder
If a door is open, a reminder chime will sound when the
headlamps or parking lamps are manually turned on
and the key is out of the ignition. To turn off the chime,
turn the headlamp switch to off or AUTO and then
back on, or close and re-open the door. In the AUTO
mode, the headlamps turn off once the ignition is
in LOCK/OFF or may remain on until the headlamp
delay ends (if enabled in the DIC). See “Exit Lighting”
underDIC Vehicle Customization (With DIC Buttons) on
page 3-67.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in P (Park).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release. For
vehicles rst sold in Canada, the transmission must be
in the P (Park) position, before the DRL lamps can
be turned off.

Automatic Headlamp System
When it is dark enough outside and the headlamp switch
is in AUTO, the automatic headlamp system will turn on
the headlamps at the normal brightness along with other
lamps such as the taillamps, sidemarker, parking lamps,
roof marker lamps, and the instrument panel lights. The
radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release. For vehicles rst sold in Canada, the
transmission must be in the P (Park) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel. Do not cover this sensor or the
system will come on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once
the vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
control is in the full bright position. SeeInstrument Panel
Brightness on page 3-17.
Fog Lamps
If your vehicle has fog lamps you can use them for
better vision in foggy or misty conditions. Your parking
lamps and/or low-beam headlamps must be on for
your fog lamps to work.
The fog lamp button is located on the left side of your
instrument panel.
#(Fog Lamps):Press the button to turn the fog lamps
on. An indicator light will glow near the button when
the fog lamps are on. Press the button again to
turn them off.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps
in the dark without turning on the headlamps.
3-16

The fog lamps will go off whenever your high-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after you
restart the vehicle, you will need to press the fog
lamp button again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Exterior Cargo Lamps
The cargo lamp can be used if more light is needed in
the cargo area of the vehicle or in the top-box
storage units. Some vehicles will only have a cargo
lamp in the driver side top box.
The cargo lamps come on by turning on the interior
dome lamps.
Instrument Panel Brightness
The knob for this feature is located next to the exterior
lamps control.
D(Instrument Panel Lights):Push the knob to
extend and then turn clockwise or counterclockwise to
brighten or dim the instrument panel lights and the radio
display. This only works if the headlamps or parking
lamps are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the knob all the way clockwise.
Dome Lamps
The dome lamps come on when any door is opened.
They turn off after all the doors are closed.
The dome lamps can also be turned on by turning the
instrument panel brightness knob, located on the
instrument panel to the left of the steering column,
clockwise to the farthest position. In this position, the
dome lamps remain on whether a door is opened
or closed.
3-17

Dome Lamp Override
The dome lamp override button is located next to the
exterior lamps control.
k(Dome Off):Press the button in and the dome
lamps remain off when a door is opened. Press the
button again to return it to the extended position so that
the dome lamps come on when a door is opened.
Entry/Exit Lighting
The vehicle has an illuminated entry/exit feature.
The dome lamps come on if the dome override button is
in the out position, when a door is opened or the key
is removed from the ignition.
Reading Lamps
If the vehicle has reading lamps, press the button
located next to the lamp to turn it on or off.
The vehicle may also have reading lamps in other
locations. The lamps cannot be adjusted.
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.

Ashtray(s) and Cigarette Lighter
If your vehicle has this feature it is located in the center
console or on the instrument panel. Pull up on the
ashtray door to open it if it is in the console or pull the
door open it if it is on the instrument panel.
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 the vehicle. Never put ammable items
in the ashtray.
To remove the ashtray, pull it out from the console or
from the slide out door. To reinstall the ashtray,
slide it back to the original position.
To use the cigarette lighter, if the vehicle has one, push
it in all the way, and let go. When it is ready for use,
it will pop back out by itself.
Do not use the lighter to plug in accessory devices. Use
the power outlets provided.
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.

9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. Turn the
knob all the way counterclockwise to turn the front
system off.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the airow
inside the vehicle. The knob can be positioned between
two modes, for a combination of those modes.
To change the current mode, select one of the following:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the instrument
panel and oor outlets. Some air is directed towards the
windshield and side window outlets. Cooler air is directed
to the upper outlets and warmer air to the oor outlets.
6(Floor):Air is directed to the oor outlets, with some
of the air directed to the windshield, side window, and
second row oor outlets. In this mode, the system
automatically selects outside air. Recirculation cannot
be selected when in Floor Mode.
-(Defog):The defog mode is used to clear the
windows of fog or moisture. Air is directed to the
windshield, oor outlets, and side window vents. In this
mode, the system turns off recirculation and runsthe air conditioning compressor unless the outside
temperature is close to freezing. The recirculation mode
cannot be selected while in the defog mode.
0(Defrost):The defrost mode is used to remove fog
or frost from the windshield more quickly. Air is
directed to the windshield and side window vents, with
some directed to the oor vents. In this mode, the
system automatically forces outside air into the vehicle.
The recirculation mode cannot be selected while in
the defrost mode. The air conditioning compressor runs
automatically in this setting, unless the outside
temperature is close to freezing.
Do not drive the vehicle until all the windows are clear.
#(Air Conditioning):Press this button 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 control is on.
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. It also helps the
system to operate 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.
3-21

:(Outside Air):Press to turn the outside air mode
on. An indicator light comes on to show that outside
air is on. Air from outside the vehicle is circulated
throughout the vehicle. The outside air mode can be
used with all modes, but it cannot be used with
the recirculation mode. Pressing this button again will
cancel the recirculation mode.
?(Recirculation):Press to turn the recirculation
mode on or off. 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,
defrost, or defogging modes. If recirculation is selected
while in one of those modes, the indicator ashes
three times and turns off. The air conditioning
compressor will also come on when this mode is
activated. 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 also be
turned off by turning off the engine.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press this button on
the right knob to turn the rear window defogger on or off.
The system automatically turns off several minutes
after it has been activated. The defogger can also be
turned off by turning off the engine. Do not drive
the vehicle until all the windows are clear.
For vehicles with heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
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.

Driver and Passenger Side Temperature
Controls
The driver and passenger side temperature buttons are
used to adjust the temperature of the air coming
through the system on the driver or passenger’s side of
the vehicle. The temperature can be adjusted even if
the system is turned off. This is possible since outside
air always ows through the system as the vehicle
is moving forward unless it is set to recirculation mode.
See “Recirculation” later in this section.
Press the + or−buttons to increase or decrease the
cabin temperature. The driver side or passenger
side temperature display shows the temperature setting
decreasing or increasing.
The passenger side temperature setting can be set to
match the driver side temperature setting by pressing
the PASS button and turning off the PASS indicator.
When the passenger side temperature setting is
set different than the driver side setting, the indicator on
the PASS button illuminates and both the driver side
and passenger side temperature displays are shown.
Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO will
be lit on the display. The current delivery mode and
fan speed will also be displayed for approximately
5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down the vehicle. The light on the
button comes on in recirculation.
