The Driver Alert System is designed to help a driver who may be becoming fatigued or who is inadvertently leaving the lane.

The Driver Alert System consists of two different functions that can be switched on together or separately.

• Driver Alert Control (DAC)
• Lane Departure Warning (LDW), see page 184

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.
