Sounding Alarm
WARNING: This page is about a different car, the 2002 Lexus LX 470. However, it is still accessible from the selected car via links, so may be relevant.
When the PANIC button is pushed for about 1 second, an alarm sounds to deter any person trying to break into or damage the vehicle. To stop the alarm, push the PANIC button for about 1 second or UNLOCK button. This function does not work when the ignition key is in the ON position.
