Buick 2005 Century - Manual (Page 163)

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 functions
can be adjusted at the steering wheel. They include
the following:
