Hummer 2010 H3 - Manual (Page 156)

7-2 Infotainment System
Theft-Deterrent Feature
THEFTLOCK ® is designed to
discourage theft of the vehicle's
radio by learning a portion of the
Vehicle Identification Number (VIN).
The radio does not operate and
LOCKED displays if the radio is
stolen or moved to a different
vehicle.
When the ignition is in the off
position, a blinking red light on the
upper left side of the radio indicates
that THEFTLOCK
® is armed.
