CD Messages
CHECK CD:If this message appears on the display
and/or the CD comes out, it could be for one of the
following reasons:
It is very hot. When the temperature returns to
normal, the CD should play.
You are driving on a very rough road. When the
road becomes smoother, the CD should play.
The CD is dirty, scratched, wet, or upside down.
The air is very humid. If so, wait about an hour
and try again.
There may have been a problem while burning
the CD.
The label may be caught in the CD player.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your GM dealer. If the radio displays
an error message, write it down and provide it to
your GM dealer when reporting the problem.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identi cation
Number (VIN). If the radio is moved to a different vehicle,
it will not operate and LOCKED will appear on the display.
With THEFTLOCK
®activated, the radio will not operate
if stolen.
Audio Steering Wheel Controls
If your vehicle has this feature, some audio controls can
be adjusted at the steering wheel.

Radio Reception
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. Static
can occur on AM stations caused by things like
storms and power lines. Try reducing the treble to
reduce this noise.
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. 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 SIGNAL to indicate interference.

Checking Coolant
The engine coolant surge tank is located in the rear of
the engine compartment. SeeEngine Compartment
Overview on page 5-12for more information on location.
{CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. Never turn the surge tank pressure
cap — even a little — when the engine and
radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the FULL
COLD mark or slightly higher.
If the LOW COOLANT message is displayed in the
Driver Information Center (DIC), it means you are low
on engine coolant. Have the system serviced by a
technician as soon as possible.
SeeDIC Warnings and Messages on page 3-40for
more information.
