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. 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
10 to 40 miles (16 to 65 km).
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.
3-114 Instrument Panel
Multi-Band Antenna
The multi-band antenna is located
on the roof of the vehicle. This
type of antenna is used with
the AM/FM radio, as well as
OnStar
®and the XM™ Satellite
Radio Service System, if the vehicle
has these features. Keep this
antenna clear of snow and ice build
up for clear radio reception. If the
vehicle has a sunroof, the
performance of the radio system
may be affected if the sunroof
is open. Loading items onto the roof
of the vehicle can interfere with
the performance of the radio system
and, if the vehicle has this feature,
OnStar
®. Make sure the multi-band
antenna is not obstructed.

vehicle should be taken in for
service. For more information on the
DIC messages, seeDriver
Information Center (DIC) on
page 3-41.The StabiliTrak light will ash on the
instrument panel cluster when the
system is both on and activated.
The system may be heard or
felt while it is working; this is normal.
The traction control disable button is
located on the instrument panel
below the climate controls.
The traction control part of
StabiliTrak can be turned off by
pressing and releasing the traction
control disable button.Traction control can be turned on
by pressing and releasing the
traction control disable button if not
automatically shut off for any
other reason.
When the traction control system is
turned off, the StabiliTrak light
and the appropriate traction control
off message will be displayed on
the DIC to warn the driver. The
vehicle will still have brake-traction
control when traction control is
off, but will not be able to use the
engine speed management system.
See “Traction Control Operation”
next for more information.
When the traction control system
has been turned off, system noises
may be heard and felt as a result
of the brake-traction control working.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle is
stuck in sand, mud, ice or snow, and
you want to “rock” the vehicle to
attempt to free it. It may also be

sooner than when on dry pavement.
Allow greater following distance
on any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of
a curve or an overpass can remain
icy when the surrounding roads
are clear. Avoid sudden steering
maneuvers and braking while on ice.Turn off cruise control, if equipped,
on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 7-6.
To get help and keep everyone
in the vehicle safe:
Turn on theHazard Warning
Flashers on page 3-5.
Tie a red cloth to an outside
mirror.
{CAUTION
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside.
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
Clear away snow from
around the base of your
vehicle, especially any that is
blocking the exhaust pipe.
Check again from time to
time to be sure snow does
not collect there.
Open a window about two
inches (5 cm) on the side of
the vehicle that is away from
the wind to bring in fresh air.
Fully open the air outlets on or
under the instrument panel.

Making Turns
Notice:Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. The vehicle could
be damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won’t strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
ash whenever signaling a turn
or lane change. Properly hooked up,
the trailer lamps also ash, telling
other drivers the vehicle is turning,
changing lanes or stopping.When towing a trailer, the arrows on
the instrument panel ash for
turns even if the bulbs on the trailer
are burned out. For this reason
you may think other drivers
are seeing the signal when they are
not. It is important to check
occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Because of the added load of the
trailer, the vehicle’s engine may
overheat on hot days, when going up
a long or steep grade with a trailer. If
the engine coolant temperature gage
indicates overheating, turn off the air
conditioning to reduce engine load,
pull off the road and stop in a safe
spot. Let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for
a few minutes before turning the
engine off.Reduce speed and shift to a lower
gearbeforestarting down a long
or steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
On a long uphill grade, shift down
and reduce the vehicle speed
to around 55 mph (88 km/h) to
reduce the possibility of the engine
and the transmission overheating.

Tow/Haul Mode
Tow/Haul is a feature that assists
when pulling a heavy trailer or
a large or heavy load. The purpose
of the Tow/Haul mode is to:
Reduce the frequency and
improve the predictability of
transmission shifts when pulling
a heavy trailer or a large or
heavy load.
Provide the same solid shift feel
when pulling a heavy trailer or a
large or heavy load as when
the vehicle is unloaded.
Improve control of vehicle speed
while requiring less throttle pedal
activity when pulling a heavy
trailer or a large or heavy load.
Increase the charging system
voltage to assist in recharging
a battery installed in a trailer.Press this button located on the
console to turn on and turn off the
Tow/Haul mode.
The Tow/Haul light on the
instrument panel will come on to
indicate that Tow/Haul mode
has been selected.
Tow/Haul may be turned off by
pressing the button again, at which
time the indicator light on the
instrument panel will turn off. The
vehicle will automatically turn
off Tow/Haul every time it is started.
Tow/Haul is designed to be most
effective when the vehicle and
trailer combined weight is at least
75 percent of the vehicle’s Gross
Combined Weight Rating (GCWR).
See Weight of the Trailer later in thissection. Tow/Haul is most useful
under the following driving
conditions:
When pulling a heavy trailer or a
large or heavy load through rolling
terrain.
When pulling a heavy trailer or a
large or heavy load in stop and go
traffic.
When pulling a heavy trailer or
a large or heavy load in busy
parking lots where improved low
speed control of the vehicle is
desired.
Operating the vehicle in Tow/Haul
when lightly loaded or with no trailer
at all will not cause damage.
However, there is no bene t to the
selection of Tow/Haul when the
vehicle is unloaded. Such a selection
when unloaded may result in
unpleasant engine and transmission
driving characteristics and reduced
fuel economy. Tow/Haul is
recommended only when pulling a
heavy trailer or a large or heavy load.
