Wrap your Lexus in a force field of security. The Lexus glass breakage sensor (GBS) helps deter theft, courtesy of a highly sensitive microphone that can actually “hear” the specific frequencies of glass being struck or broken. If the GBS detects an object striking the glass, a warn-away alarm will sound. In the event that breaking glass is detected, your vehicle’s factory-installed theft-deterrent system will immediately activate and disable the starter. The GBS is designed to ignore other noises and the sensitivity is adjustable, helping to prevent “false alarms.”
