Radio Reception
Frequency interference and static can occur
during normal radio reception if items such as
cellphone 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 reduces 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 stereo gives the best sound, but FM signals
reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
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
the loss of XM™ signal for a period of time.
The radio might display NO XM SIGNAL to
indicate interference.

Competitive Driving Mode (STS-V)
The driver can select this optional handling mode
by pressing the Traction Control button, located
near the shift lever, twice within ve seconds.
Competitive driving mode allows the driver to have
control of the power applied to the rear wheels,
while the StabiliTrak
®system helps steer the
vehicle by selective brake application. In
competitive mode, the levels at which StabiliTrak
®
is engaged have been modied to better suit a
performance driving environment. When the
traction control warning light is on, the Traction
Control System will not be operating. Adjust your
driving accordingly.
When you press the Traction Control button again,
the Traction Control System will be on. The
traction engaged symbol will be displayed
temporarily in the DIC and a chime will be heard.
SeeDIC Warnings and Messages on page 264
for more information.
Magnetic Ride Control
Your vehicle may have Magnetic Ride Control that
automatically adjusts the ride of your vehicle.
Automatic ride control is achieved through
a computer used to control and monitor the
suspension system. The controller receives input
from various sensors to determine the proper
system response. If the controller detects a
problem within the system, the DIC will display a
SERVICE SUSPENSION SYS message. See
DIC Warnings and Messages on page 264
for more information. See your dealer for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It
works like a standard axle most of the time, but
when one of the rear wheels has no traction
and the other does, this feature will allow
the wheel with traction to move the vehicle.
325

StabiliTrak®System
Your vehicle is equipped with a vehicle stability
enhancement system called StabiliTrak®.It
is an advanced computer controlled system that
assists you with directional control of the vehicle in
difficult driving conditions.
StabiliTrak
®activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling.
StabiliTrak
®selectively applies braking pressure at
any one of the vehicle’s brakes to help steer the
vehicle in the direction which you are steering.
When the system activates, a STABILITY SYS
ACTIVE message will be displayed on the Driver
Information Center. SeeDIC Warnings and
Messages on page 264. You may also hear a
noise or feel vibration in the brake pedal. This is
normal. Continue to steer the vehicle in the
direction you want it to go.If there is a problem detected with StabiliTrak
®,a
SERVICE STABILITY SYS message will be
displayed on the Driver Information Center. See
DIC Warnings and Messages on page 264. When
this message is displayed, the system is not
operational. Driving should be adjusted
accordingly.
StabiliTrak
®comes on automatically whenever you
start your vehicle. To help assist you with
directional control of the vehicle, you should
always leave the system on. You can turn
StabiliTrak
®off if you ever need to through the
TC (traction control) on/off button. SeeTraction
Control System (TCS) on page 323.
If your vehicle is in cruise control when the
StabiliTrak
®activates, the cruise control will
automatically disengage. When road conditions
allow you to safely use it again, you may reengage
the cruise control. SeeCruise Control on
page 193orAdaptive Cruise Control on page 197
for more information.

Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such as
after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts
in GM dealerships all across North America. They
will be ready and willing to help if you need it.

Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the
lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with
a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your rearview mirrors
and your instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.

Towing
Towing Your Vehicle
Consult your dealer or a professional towing
service if you need to have your disabled vehicle
towed. SeeRoadside Service on page 531.
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.
Here are some important things to consider before
you do recreational vehicle towing:
What is the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer’s recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they
can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional
for additional advice and equipment
recommendations.
Is your vehicle ready to be towed? Just as
you would prepare your vehicle for a long
trip, you will want to make sure your vehicle is
prepared to be towed. SeeBefore Leaving
on a Long Trip on page 340.
