XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast to coast. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. The radio may
display NO XM SIGNAL to indicate interference.
Cellular Phone Usage
Cellular phone usage may cause interference with your
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
is 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.
Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. If the surface of a CD is soiled,
dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling CDs. Pick up CDs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of the CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.

If there is a problem detected with StabiliTrak®,a
Service Stability System message will be displayed on
the Driver Information Center. SeeDIC Warnings
and Messages on page 3-65. 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. See
Traction Control System (TCS) (CTS) on page 4-8
orTraction Control System (TCS) (CTS-V) on page 4-9.
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 (CTS) on page 3-12orCruise
Control (CTS-V) on page 3-16for more information.
Panic Brake Assist
Your vehicle has a panic brake assist system that
monitors the intention of the driver while braking. If the
system senses that the driver has applied hard/fast
pressure to the brake pedal, the system will generate
additional pressure, making it easier for the driver to
maintain brake application. When this happens the brake
pedal will feel easier to push. Just hold the brake pedal
down rmly and let the system work for you. You may feel
the brakes vibrate, or you may notice some noise but this
is normal. The brakes will return to normal operation after
the brake pedal has been released.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Speed Variable Assist Steering
If your vehicle has this system, it varies the amount of
effort required to steer the vehicle in relation to the
speed of the vehicle.
