Buick 2006 Rendezvous - Manual (Page 274)

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.
