Panic Mode Function
WARNING: This page is about a different car, the 2003 Lexus IS 300 and 2002 Lexus IS 300. However, it is still accessible from the selected car via links, so may be relevant.
When the lock switch on the transmitter is kept pressed for approximately 2.5 seconds, the theft alarm goes on, and the headlights and taillights flash through the communication of the body ECU etc. At this time, when any SW on the transmitter is pressed, the panic mode is cancelled, the theft alarm is stopped, and the headlights and taillights go off.
