Turn steering wheel gently into opposite
direction, if lane change is intended.
When the system steers to correct the
trajectory of the vehicle, flashes
yellow on the cluster. Lane keeping
assist does not continuously steer the
vehicle.
Unintended lane departure is not
assumed by the system when the turn
lights are operated and during few
seconds after turn lights have been
switched off.
The system will inform the driver with
a message and a chime if there is an
ongoing correction for more than ten
seconds. If the driver is still unable
to keep the vehicle in the lane, the
correction interrupts after a short time.
When hands-off driving is detected
during a correction a warning message
appears on the cluster, accompanied by
a warning chime. Every further hands-
off detection prolongs the warning chime
duration.
A lane departure warning on the cluster
alerts when the system cannot hold the
vehicle within the lane and immediate
driver´s action is required.
Note
The system might be inactive if it detects
lanes that are too narrow, too wide or too
curved.
