head-on collision
The subfunction can help a distracted driver who
does not notice that the car is drifting into the
oncoming lane.
The function can assist by guiding the car back to its
own lane.
Oncoming vehicles
Your car
The function is active within the speed range
60-140 km/h (37-87 mph) on roads with clearly
visible lane markings/lines.
If the car is about to leave its own lane while an
oncoming vehicle is approaching at the same
time, the function can help the driver to steer the
car back into its own lane.
However, the function does not intervene with
steering assistance if the direction indicator is
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 display
indicates that this has occurred via a text mes-
sage:
•
Collision avoidance assistance
Automatic intervention
WARNING
•
The "Steering assistance at risk of
oncoming collision" subfunction is sup-
plementary driver support intended to
improve driving safety – it cannot handle
all situations in all traffic, weather and
road conditions.
•
Steering assistance is only activated if
there is a high risk of collision – you must
therefore never wait for the function to
intervene.
•
The function is not a substitute for the
driver's attention and judgement. The
driver is always responsible for ensuring
the car is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.
