The Lane Assist system is intervening by
adjusting the steering.
Switching the lane assist system on or o
In some countries, the Lane Assist system is al-
ways activated when the ignition is switched
on. It is switched on and o and displayed in
the infotainment system’s Vehicle menu and
also in the driving assistants menu displayed on
the instrument cluster, by pressing the button
on the multifunction steering wheel.
The Lane Assist system is designed to actively
intervene as of approximately 65 km/h (40
mph) and if it has detected the lane boundaries
(system status: active).
When a turn signal is activated, the system
temporarily switches to a passive state in the in-
dicated direction and is available for operation
in the opposite direction.
An energetic rotation or rectification of the
steering wheel by the driver causes the system
to temporarily switch to a passive state.
When Lane Assist is switched o, the yel-
low disconnection warning lamp lights up
in the instrument cluster (depending on
the country).
Note
If a system fault persists, Lane Assist may
switch o automatically.
Driver intervention prompt
If the steering is not corrected manually, the
system prompts the driver an indication on the
instrument cluster display and audible warn-
ings.
If no reaction is obtained from the driver, the
system switches to a passive state.
Depending on the equipment, Emergency As-
sist is activated.
Regardless of the steering manoeuvres, an in-
dication on the instrument cluster display and
audible warnings also prompt the driver to drive
in the middle of the lane if the steering correc-
tion lasts longer than reasonable.
Steering wheel vibration
The following situations may result in a steering
wheel vibration:
●
The lane ceases to be recognised during a
sudden intervention in the steering by the sys-
tem.
It is also possible to select steering wheel vibra-
tion in the Vehicle menu of the infotainment
system. In this case, when a vehicle with Lane
Assist switched on crosses over a detected lane
marking, the steering wheel will vibrate.
Troubleshooting
