2007 CHEVROLET AVALANCHE roof

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 PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only your DRL lamps will
be on. The taillamps, sidemarker, and other lamps
will not be on. The instrument panel will not be
lit up either.
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 transaxle
must be in the PARK (P) position, before the
DRL lamps can be turned off.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp
system will turn on your 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 transaxle must be in the PARK (P) position,
before the automatic headlamp system can
be turned off.
Your vehicle has a light sensor located on the
top of the instrument panel. Be sure it is not
covered, or the system will be on whenever the
ignition is on.
The system may also turn on your headlamps
when driving through a parking garage, heavy
overcast weather, or a tunnel. This is normal.

Care of Your CDs and DVDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans
the bottom surface of the disc. If the surface of a
CD is damaged, such as cracked, broken, or
scratched, the CD does not play properly or not
at all. If the surface of a CD is soiled, take a soft,
lint free cloth or dampen a clean, soft cloth in
a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface.
Pick up CDs by grasping the outer edges or
the edge of the hole and the outer edge.
Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the
lens of the CD optics with lubricants internal to
the CD mechanism.
Fixed Mast Antenna
The xed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast
is still tightened to its base. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear
of snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the best
performance from the XM™ system if the sunroof
is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

CAUTION: (Continued)

Heavy loads on the roof raise the
vehicle’s center of gravity, making it
more likely to roll over. You can be
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
Keep cargo in the cargo area as far
forward and low as possible.
There are some important things to remember
about how to load your vehicle.
The heaviest things should be on the load
oor and forward of the rear axle. Put
heavier items as far forward as you can.
Be sure the load is secured properly, so
driving on the off-road terrain does not
toss things around.
You will nd other important information in this
manual. SeeLoading Your Vehicle on page 402,
Luggage Carrier on page 171, andTires on
page 492.
Environmental Concerns
Off-road driving can provide wholesome and
satisfying recreation. However, it also raises
environmental concerns. We recognize these
concerns and urge every off-roader to follow these
basic rules for protecting the environment:
Always use established trails, roads, and areas
that have been specially set aside for public
off-road recreational driving; obey all
posted regulations.
Avoid any driving practice that could damage
the environment — shrubs, owers, trees,
grasses — or disturb wildlife. This includes
wheel-spinning, breaking down trees, or
unnecessary driving through streams or over
soft ground.
Always carry a litter bag — make sure all
refuse is removed from any campsite
before leaving.
Take extreme care with open res where
permitted, camp stoves, and lanterns.
Never park your vehicle over dry grass or
other combustible materials that could
catch re from the heat of the vehicle’s
exhaust system.
