top-box storage compartment.
Cargo Tie Downs
The vehicle has cargo tie downs,
located in the rear cargo area.
These can be used to secure cargo.
The tie downs can also be used to
secure the cargo cover panel strap
system, if the vehicle has one. For
more information see Cargo Cover
Panels on page 4‑6.
Roof Rack System
{WARNING
If something is carried on top of
the vehicle that is longer or wider
than the roof rack— like paneling,
plywood, or a mattress— the wind
can catch it while the vehicle is
being driven. The item being
carried could be violently torn off,
and this could cause a collision,
and damage the vehicle.
Never carry something longer
or wider than the roof rack on
top of the vehicle unless using a
GM Certified accessory carrier.
For vehicles with a roof rack, the
rack can be used to load items.
For roof racks that do not have
crossrails included, GM Certified
crossrails can be purchased as an
accessory. See your dealer for
additional information. Notice:
Loading cargo on the
roof rack that weighs more than
91 kg (200 lbs) or hangs over the
rear or sides of the vehicle may
damage the vehicle. Load cargo
so that it rests evenly between
the crossrails, making sure to
fasten cargo securely.
To prevent damage or loss of cargo
when driving, check to make sure
crossrails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle’ s center
of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to
make sure the cargo remains in
its place.

4-14 Storage
Do not exceed the maximum vehicle
capacity when loading the vehicle.
For more information on vehicle
capacity and loading, seeVehicle
Load Limits on page 9‑24.
.If small heavy objects are
placed on the roof, cut a piece of
3/8 inch plywood to fit inside the
crossrails and siderails to spread
the load. Tie the plywood to the
siderail supports.
.Tie the load and secure it
to the crossrails or the siderail
supports. Use the crossrails only
to keep the load from sliding.
To move a crossrail, lift the
release lever up, on both sides
of the rail. Then slide the
crossrail to the desired position
balancing the force side to side.
Press the release lever down on
both sides of the rail, down to
tighten it. Try to slide the
crossrail back and forth slightly
to make sure it is tight.
.To carry long items, move the
crossrails as far apart as
possible. Tie the load to the
crossrails and the siderails or
siderail supports. Also tie the
load to the bumpers, but do not
tie the load so tightly that the
crossrails or siderails are
damaged.
.After moving a crossrail, be
sure it is securely locked into
the siderail.
A Center High-Mounted Stoplamp
(CHMSL) is located above the rear
window glass.
Make sure items loaded on the roof
of the vehicle do not block or
damage the CHMSL.

This system provides a way to
replace up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Do not use this system with any
garage door opener that does not
have the stop and reverse feature.
This includes any garage door
opener model manufactured before
April 1, 1982.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to have
another person assist with
programming the transmitter.
Be sure to keep the original remote
control transmitter for use in other
vehicles, as well as for future
programming. Only the original
remote control transmitter is needed
for Fixed Code programming. The
programmed buttons should be
erased when the vehicle is sold orthe lease ends. See
“Erasing
Universal Home Remote Buttons”
in this section.
Park the vehicle outside of the
garage when programming a garage

Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug
the item from the accessory
power outlet.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night.

Black plate (13,1)Chevrolet Avalanche Owner Manual - 2011
Infotainment System 7-13
Static can also occur when things
like storms and power lines interfere
with radio reception. When this
happens, try reducing the treble on
the radio.
FM Stereo
FM signals only reach about
16 to 65 km (10 to 40 miles).
Although the radio has a built-in
electronic circuit that automatically
works to reduce interference, some
static can occur, especially around
tall buildings or hills, causing the
sound to fade in and out.
XM™Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from coast to
coast in the 48 contiguous United
States, and in Canada. Just as
with FM, tall buildings or hills can
interfere with satellite radio signals,
causing the sound to fade in and
out. In addition, traveling or standing
under heavy foliage, bridges,
garages, or tunnels may cause loss
of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's radio.
This interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to the
radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Fixed Mast Antenna
The fixed mast antenna can
withstand most car washes without
being damaged as long as it is
securely attached to the base.
If the mast becomes slightly bent,
straighten it out by hand. If the mast
is badly bent, replace it.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten by
hand until fully seated plus
one quarter turn.
Satellite Radio Antenna
The XM Satellite Radio antenna is
located on the roof of the vehicle.
Keep the antenna clear of
obstructions for clear radio
reception.
If the vehicle has a sunroof, the
performance of the XM system
(if equipped) may be affected if the
sunroof is open.
