Radio Reception
You may experience frequency interference
and static 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 will 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 your radio.
FM Stereo
FM stereo will give the best sound, but FM signals
will 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
loss of XM signal for a period of time. The
radio may display NO XM SIGNAL to indicate
interference.

The SERVICE TRACTION CONTROL message,
the traction control system warning light and
the StabiliTrak
®warning light will come on to let
you know if there is a problem with the traction
control system. SeeDIC Warnings and Messages
on page 246.
When this light and the SERVICE TRACTION
CONTROL message are on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically
comes on whenever you start your vehicle. To
limit wheel spin, especially in slippery road
conditions, you should always leave the system
on. But you can turn the traction control system off
if you ever need to.
You can turn the system on or off at any time by
pressing the traction control system button located
on the console or on the end of the column
shifter. The DIC will display TRACTION CONTROL
OFF when you press the button.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modications on page 353for more
information.
Magnetic Ride Control
Your vehicle may have a feature called 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. SeeDIC Warnings
and Messages on page 246for more information. If
this message appears, have your vehicle serviced
at your dealership.
Electronically Controlled Air Ride
Suspension
If you have a Cadillac Professional Vehicle, you
may have a feature called Electronically Controlled
Air Suspension. Air ride control is achieved through
a computer used to control and monitor the system.
