Warning signals
The Intelligent Key system is equipped with a function that is designed to minimize improper operations and to help prevent the vehicle from being stolen. The warning buzzer sounds and the warning display appears on the vehicle information display when improper operations are detected.

When the buzzer sounds and the warning display appears, be sure to check both the vehicle and the Intelligent Key.
