Output Signal Item
FUNCTION DESCRIPTION
• Operates when the vehicle speed is 60 km/h or higher.
• Detects the steering status and judges the attentiveness of the driver. The driver's attentiveness is shown on
the vehicle information display in eight stages (level indicator).
• When it is judged from the degree of minor swerving in the steering operation that the vehicle is drifting, the
driver is prompted to exert caution by the drift warning, which displays on the combination meter, and by a
buzzer sound.
• When the engine is stopped, the system is reset.
• When the level indicator on the drift warning display becomes 1, the system warns the driver with a buzzer
sound.
OPERATION DESCRIPTION
• The DAA (Driver Attention Alert) is controlled by the around view monitor control unit.
• ON/OFF of the DAA is performed by using the combination meter.
• The steering angle sensor detects the degree of swerving in the steering operation.
• When the around view monitor control unit judges that the steering operation is drifting (when the level indi-
cator in the drift warning display becomes 1), the following control is performed and the driver is warned.
- Transmits the buzzer output signal to the combination meter and sounds the buzzer.
