Issuing a warning

If the vehicle begins leaving the lane and a lane marking has been detected, the steering wheel begins vibrating.

If the turn signal is set before the lane is changed, a warning is not issued.

The warning is canceled:

▷ Automatically after approx. 3 seconds.
▷ After the vehicle returns to its lane.

▷ During heavy brake application.
▷ When the turn signal flashes.
