Tamper Alert
WARNING: This page is about a different car, the 2006 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
The VTA tamper alert feature will pulse the horn three times upon VTA disarming, if the alarm was triggered and has since timed-out, or if the battery has been disconnected and reconnected. This feature alerts the vehicle operator that the VTA alarm was activated while the vehicle was unattended.
