Steering assistance upon risk of
lane departure
The subfunction's task is to help the driver
reduce the risk of the car accidentally leaving the
road by actively steering the car back onto the
road.
The function is active within the speed range
65-140 km/h (40-87 mph) on roads with clearly
visible lane markings/lines.
A camera scans the edges of the road and the
painted side markings. If the car is about to leave
the side of the road, the car is steered back onto
the road and if the steering intervention is not
enough to avoid run-off, the brakes are also acti-
vated.
The function does not intervene however with
steering assistance or braking if the direction
indicators are used and if the function detects
that the driver is actively driving the car, activation
of the function will be delayed.
After automatic engagement, the driver indicates
that this has occurred via a text message:
•
Collision avoidance
assistance: Automatic intervention
Level of steering assistance
The function has two activation levels:
•
Steering assistance only
•
Steering assistance with brake intervention
Steering assistance only
Intervention with steering assistance.
Steering assistance with brake intervention
Intervention with steering assistance and braking.
Brake intervention helps in situations where
steering assistance alone is not sufficient. The
brake force is adapted automatically depending
on the situation at the time of road run-off.
Activating/deactivating Steering
assistance in the event of run-off risk
The function can be selected - the driver can
choose to have it On or Off.
Proceed as follows to switch it off:
1.
Select
Settings My Car IntelliSafe in
the centre display's top view.
2.
Deselect
Collision Avoidance Assistance.
> The function is then disengaged.
NOTE
When the Collision Avoid. Assistance
function is deactivated, all subfunctions are
switched off:
•
Steering assistance at risk of lane depar-
ture
•
Steering assistance at risk of oncoming
collision
•
Steering assistance at risk of rear-end
collision
Even though it is possible to deactivate the
function, it is advisable for the driver to always
have it activated since it improves driving
safety in most cases.
