Lane assistance steers the car back into its lane.
Lane assistance warns with steering wheel vibrations
107 The steering wheel vibration varies - the longer the car remains outside the lane lines, the longer the vibration.
See the heading "Assistance alternatives for LKA" in the section "Activating/Deactivating Lane Keeping Aid".
108
Depending on settings, lane assistance acts in
accordance with the following:
• Assist 108 activated: When the car is
approaching a lane line, LKA will actively
steer the car back into its lane by applying a
slight torque to the steering wheel.
• Warning 108
activated: If the car is about to
cross a lane line, the driver is warned by
means of vibrations in the steering wheel.
NOTE
When a direction indicator is switched on,
there are no steering corrections or alerts
from Lane assistance.
