376Lane Keeping Aid limitations
In certain demanding driving conditions, Lane
Keeping Aid may not be able to properly assist
the driver. In these situations, it is recommended
that the function be deactivated.
Examples of such situations include:
road work
winter driving conditions
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's
side markings
when the power steering works at reduced
power, e.g. during cooling due to overheating
(see section “Speed-dependent steering
force”).
NOTE The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

380 Steering assistance at risk of
collision
The Collision avoidance assistance function
is intended to help the driver reduce the risk of
the vehicle inadvertently veering from the traffic
lane and/or colliding with another vehicle or
obstacle by actively steering the vehicle back
into the lane and/or swerving out of the way.
Collision avoidance assistance consists of
three sub-functions:
Run-Off Mitigation with steering assistance
Steering assistance during collision risks
from oncoming traffic
Steering assistance during collision risks
from behind*
After the system has automatically intervened,
this text message will appear in the instrument
panel:
Collision avoidance assistance –
Automatic intervention
NOTE It is always the driver who must decide how
much the vehicle should be in control – the
vehicle can never take command.

Run-Off Mitigation with steering
assistance
This sub-function is intended to help reduce the
risk of the vehicle inadvertently running off the
road by actively steering the vehicle back onto
the road.
The function is active at speeds between
65-140 km/h (40-87 mph) on roads with clearly
visible traffic lane markings/lines.
The system uses a camera to monitor the edges
of the road and the painted side marker lines. If
the vehicle is about to cross the edge of the road,
the function will attempt to steer the vehicle back
onto the road. If this is not sufficient to keep the
vehicle on the road, the brakes will also be
applied.
However, the function will not provide either
steering assistance or braking if the turn signal is
used. The function will also not be activated if it
detects that the driver is actively operating the
vehicle.
After the system has automatically intervened,
this text message will appear in the instrument
panel: Collision avoidance assistance –
Automatic intervention
WARNING
The "Steering assistance at risk of run-
off" subfunction is supplementary driver
support intended to help improve driving
safety – it cannot handle all situations in
all traffic, weather and road conditions.
The function cannot detect barriers, rails
or similar obstacles at the side of the
road.
"Steering assistance at risk of run-off" is
not a substitute for the driver's attention
and judgment. The driver is always
responsible for ensuring the vehicle is
driven in a safe manner, at the appropri-
ate speed, with an appropriate distance to
other vehicles, and in accordance with
current traffic rules and regulations.
