Driver Alert System
The Driver Alert System is designed to help a driver who may be becoming fatigued or who is inadvertently leaving the lane.
Introduction
The Driver Alert System consists of two different functions that can be switched on together or separately.
- Driver Alert Control (DAC), see Driver Alert Control (DAC) – introduction
- Lane Departure Warning (LDW)1, see Lane Departure Warning (LDW) – introduction
or
- Lane Keeping Aid (LKA)1, see Lane Keeping Aid (LKA) – introduction
When one or both of the functions has been switched on, it is in standby mode and is activated when the vehicle exceeds a speed of 40 mph (65 km/h).
The function deactivates if the vehicle's speed goes under 37 mph (60 km/h).
Both functions use a camera that is dependent on the road/lane being clearly marked by painted lines on each side.
Warning
The Driver Alert System does not function in all situations and is designed to be a supplementary aid. It is not, however, intended to replace the driver’s attention and judgement.
