2008 CHEVROLET SUBURBAN roof

Auxiliary Roof Mounted Lamp
If your vehicle has this feature, this button includes
wiring provisions for a dealer or a qualied service
center to install an auxiliary roof lamp.
This button is located on
the overhead console.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the bottom of the button will
activate the lamp and illuminate an indicator light at the
bottom of this button. Pressing the top of the button
will turn off the roof mounted lamp and indicator.
The emergency roof lamp circuit is fused at 30 amps,
so the total current draw of the attached lamps
should be less than this value. The attachment points
for the roof lamp circuits are two blunt cut wires located
above the overhead console, a dark green switched
power wire and a black ground wire.
For further information on roof mount emergency lamp
installation, please visit the GM Uptter website at
www.gmuptters.com or contact your dealer.If your vehicle has this button, your vehicle may have
the snow plow prep package. For further information see
Adding a Snow Plow or Similar Equipment on
page 4-41.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights
and is located next to the exterior lamp control.
Push the knob to extend out and then it can be turned.
Turn the knob clockwise or counterclockwise to
brighten or dim the instrument panel lights. Turning the
knob to the farthest clockwise position turns on the
dome lamps.
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 next to
the exterior lamps control, clockwise to the farthest
position. In this position, the dome lamps remain
on whether a door is opened or closed.

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
through tunnels could cause loss of the XM signal for a
period of time. The radio may display NO XM SIGNAL
to indicate interference.
Rear Side Window Antenna
The AM-FM antenna is located in the passenger rear
side windows. Make sure the inside surfaces of the rear
side windows are not scratched and that the lines on
the glass are not damaged. If the inside surfaces
are damaged, they could interfere with radio reception.
Notice:Using a razor blade or sharp object to
clear the inside of the rear side windows may
affect radio reception or damage the rear window
defogger. Repairs would not be covered by your
warranty. Do not clear the inside of the rear
side windows with sharp objects.Notice:Do not apply aftermarket glass tinting
with metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
antenna due to metallic tinting materials will not
be covered by your warranty.
Because this antenna is built into the rear side windows,
there is a reduced risk of damage caused by car
washes and vandals.
If an aftermarket cellular telephone is added to the
vehicle, and the antenna needs to be attached to the
glass, make the grid lines for the AM-FM antennas are
not damaged or the cellular telephone antenna is not
placed over the grid lines.
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.
Loading items onto the roof of your vehicle can interfere
with the performance of the XM™ system. Make sure
that the XM™ satellite antenna is not obstructed.

Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields, if the vehicle has them, are properly
attached. Be sure you read all the information about
your four-wheel-drive or all-wheel-drive vehicle in
this manual. Is there enough fuel? Is the spare tire fully
inated? Are the uid levels up where they should
be? What are the local laws that apply to off-roading
where you will be driving? If you do not know, you
should check with law enforcement people in the area.
Will you be on someone’s private land? If so, be
sure to get the necessary permission.
Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by ying objects. Secure the cargo
properly.
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.

Keep in mind that reserve capacity numbers are
intended as a guide when selecting the amount of
equipment or cargo your vehicle can carry. If you are
unsure of your vehicle’s front, rear, or total weight, go to
a weigh station and weigh your vehicle. Your
dealer/retailer can also help you with this.
The total vehicle reserve capacity for your vehicle can
be found in the lower right corner of the Certication/Tire
label as shown previously.
See your dealer/retailer for additional advice and
information about using a snow plow on your vehicle.
Also, seeLoading the Vehicle on page 4-35.
Emergency Roof Lamp Provisions
Vehicles with the RPO VYU snow plow prep package
also have an emergency roof lamp provision package,
RPO TRW. Wiring for the emergency roof lamp is
provided above the overhead console. SeeAuxiliary
Roof Mounted Lamp on page 3-18for switch location.
Towing
Towing Your Vehicle
To avoid vehicle damage, a platform or atbed trailer
should be used to transport this vehicle. Consult
your dealer/retailer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page 7-8.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing, towing your vehicle
with all four wheels on the ground, and dolly towing,
towing your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”.
With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing”, following.
