Vehicle Theft Alarm
The VTA is available in two different configurations, one is designed for vehicles manufactured for sale in North America; while the other is designed for vehicles manufactured for sale in markets outside of North America. In addition, the VTA for export is available in two versions: base and premium. All vehicles equipped with VTA are also equipped with the Remote Keyless Entry (RKE) system and the Sentry Key Immobilizer System (SKIS), regardless of their market destination.
The North American and export base version of the VTA system provide perimeter vehicle protection by monitoring the vehicle doors, the ignition switch, the trunk, and for vehicles built for certain markets where it is required equipment, the hood. If unauthorized vehicle use or tampering is detected, these systems respond by pulsing the vehicle horn as an audible deterrent and flashing certain exterior lamps as a visual deterrent.
The export premium version of the VTA system is only available in vehicles manufactured for sale in certain markets where it is required equipment. The export premium version of the VTA provides the same perimeter protection features as the base version, but adds interior vehicle intrusion protection. The export premium VTA also supplements the pulsing horn feature of the base version with a siren as the audible deterrent, while retaining the flashing exterior lamps as the visual deterrent.
