Buick 2007 Rendezvous - Manual (Page 296)

Theft-Deterrent Feature
THEFTLOCK ® is designed to discourage theft of
your vehicle’s radio. It works by using a secret
code to disable all radio functions whenever
battery power is removed and the radio is placed
in a different vehicle. This feature requires no
user input to be activated. The radio is
automatically armed when it is put into the vehicle
for the first time.
When the ignition is turned off, the blinking red
light indicates that THEFTLOCK
® is armed.
If THEFTLOCK ® is activated, the radio will not
operate if stolen. The radio will display LOCKED
and a red LED indicator light will come on
above the key symbol to indicate a locked
condition. If this occurs, the radio will need to be
returned to your GM dealer.
Audio Steering Wheel Controls
If your vehicle has this feature, some audio
controls can be adjusted at the steering wheel.
They include the following:
SOURCE: When listening to the radio, press this
button to play a cassette tape, CD, or a DVD
(if equipped). If a cassette tape, and CD, and/or
DVD are loaded, the system will go to the
tape play first. The inactive tape, CD, or DVD will
remain safely inside the player for future
listening.
MUTE: Press this button to silence the system.
Press it again, or any other radio button, to turn the
sound on.
