372 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.

The function will be deactivated.
NOTE When the
Collision avoidance assistance
function is deactivated, all subfunctions of the
following are deactivated:
• Steering assistance at risk of run-off
• Steering assistance at risk of head-on
collision
• Steering assistance during collision risks
from behind*
Although it is possible to deactivate the func-
tion, the driver is advised to keep it activated
since it can help improve driving safety in
most cases.

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.

(p. 372) Limitations of Run-Off Mitigation
with steering assistance
In certain demanding driving conditions, the
function may not be able to properly assist the
driver. In these situations, it is recommended
that it is turned off.
Examples of such situations include:
• road work
• winter driving conditions
• narrow roads
• 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 overheat-
ing (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".

(p. 272) Steering assistance during collision
risks from oncoming traffic
This sub-function can help assist a distracted
driver who has not noticed that the vehicle is
veering into oncoming traffic. The function provides assistance by swerving your vehi-
cle back into your own lane.
Oncoming vehicles
Own vehicle
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly
visible traffic lane markings/lines.
If your vehicle is starting to veer from your own
lane and a vehicle is approaching from the oppo-
site direction, this function can help the driver
steer the vehicle back into its own lane. However, the function will not provide steering
assistance 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 head-
on collision" subfunction is supplemen-
tary driver support intended to improve
driving safety – it cannot handle all situa-
tions in all traffic, weather and road condi-
tions.
• Pilot Assist 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 judgment. The driver
is always responsible for ensuring the
vehicle 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.

(p. 372) Limitations of steering assistance
during collision risks from
oncoming traffic
The function may have limited functionality in
certain situations and not intervene, e.g.:
•
for smaller vehicles such as motorcycles
• on roads that do not have clear lane mark-
ings
• if more than half of your vehicle has moved
into the adjacent lane
• outside the speed range 60-140 km/h
(37-87 mph)
• when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").
Functionality may also be reduced in other situa-
tions, such as: • road work
• winter driving conditions
• narrow roads
• poor road surfaces
• a very sporty driving style
• bad weather with reduced visibility.
In these demanding driving conditions, the func-
tion may not be able to properly assist the driver.
In these situations, it is recommended that it is
turned off.
