Puddle Lamps
If your vehicle has puddle lamps, they come on when
the unlock button on the Remote Keyless Entry (RKE)
Transmitter is pressed. The lamps time out or turn
off once the engine is started.
Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps, the
control is located next to the exterior lamps control
on the instrument panel, to the left of the steering
column.
The ignition must be in the ON/RUN position for the fog
lamps to come on.
Press the button to turn the fog lamps on or off. A light
will come on in the instrument panel cluster.
When the fog lamps are turned on, the parking lamps
automatically turn on.
When the headlamps are changed to high-beam, the
fog lamps also go off. When the high-beam headlamps
are turned off, the fog lamps will come on again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
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.

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.
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 the vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
If the vehicle has a sunroof, the performance of the
XM™ system may be affected if the sunroof is open.
Loading items onto the roof of the vehicle can interfere
with the performance of the XM™ system. Make
sure the XM™ Satellite Radio antenna is not obstructed.

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.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 4-36andTires
on page 5-68.

Keep in mind that reserve capacity numbers are
intended as a guide when selecting the amount of
equipment or cargo your truck 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 Your Vehicle on page 4-36.
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 3-20for switch location.
Truck-Camper Loading Information
A vehicle specic Truck-Camper Loading
information label is attached to the inside of your
vehicle’s glove box. This label will tell you if
your vehicle can carry a slide-in camper, how
much of a load your vehicle can carry, and how to
correctly spread out the load. Also, it will help
you match the right slide-in camper to your vehicle.
When you carry a slide-in camper, the total
cargo load of your vehicle is the weight of the
camper, plus the following:
Everything else added to the camper after it
left the factory
Everything in the camper
All the people inside
The Cargo Weight Rating (CWR) is the maximum
weight of the load your vehicle can carry. It does not
include the weight of the people inside. But, you
can gure about 150 lbs (68 kg) for each seat.
The total cargo load must not be more than your
vehicle’s CWR.
