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 overheating
(see section “Speed-dependent steering
force”).
NOTE The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

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.

||DRIVER SUPPORT
* Option/accessory.
384 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.

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)

386 Steering assistance during collision
risks from behind*
If you become distracted and do not notice your
vehicle starting to veer out of the lane while
another vehicle is approaching from behind or is
in your vehicle's blind spot, this sub-function can
help provide assistance. The function provides assistance by steering your vehi-
cle back into your own lane.
Another vehicle in blind spot zone
Own vehicle
If your vehicle is beginning to veer out of your
lane while another vehicle is in your blind spot or
another vehicle is rapidly approaching in the next
lane, this function can help the driver steer the
vehicle back into its own lane.
Even if the driver intentionally changes lanes
using a turn signal without noticing another vehi- cle approaching, the function can provide assis-
tance.
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly
visible traffic lane markings/lines.
After the system has automatically intervened,
this text message will appear in the instrument
panel:

camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".
In addition to the camera and radar sensor, the
function also uses the vehicle's rearward-facing
radar, which has certain general limitations the
driver should be aware of. See additional informa-
tion in the section "BLIS limitations".

390 Park Assist*
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating
distances to obstacles using audible signals and
graphics in the center display. Display view showing obstacle zones and sensor sec-
tors.
The center display shows an overview of the vehi-
cle in relation to objects that have been detected.
The marked sector indicates where the obstacle
is located. The closer the vehicle symbol is to a
marked sector forward/rearward, the closer the
detected obstacle is to your vehicle.
The side sectors change color as the distance
between the vehicle and an object decreases.
The audible signals will also speed up the closer
the obstacle is to the vehicle. The volume of the
audio system will be automatically lowered. Audible signals for obstacles in front and to the
sides of the vehicle are active when the vehicle is
moving but will cease after the vehicle has been
stationary for approx. 2 seconds. Audible signals
for obstacles behind the vehicle will remain active
even when the vehicle is stationary.
If a detected obstacle is within approx. 30 cm
(1 ft) from the front or rear of the vehicle, the
tone will become constant and the active sen-
sor's field closest to the vehicle symbol will be
filled in.
At distances within approx. 25 cm (0.8 ft) from an
obstacle to the sides of the vehicle, an rapid puls-
ing signal will be given and the active sector
fields will change color from ORANGE to RED.
The volume of the Park Assist audible signals
can be adjusted while the signal is being given
using the >II knob or in the center display's Top
view under Settings.
NOTE
Besides in the sector closest to the vehi-
cle symbol, audible warnings are only pro-
vided for objects located directly in the
vehicle's path.
WARNING
The Parking Assist function is supple-
mentary driver support intended to facili-
tate driving and help make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.
The parking sensors have dead/blind
spots where objects cannot be detected.
Pay particular attention to people and
animals near the vehicle.
Parking Assist 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.
