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 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".

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.

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.

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.

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.

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, the closer the detected obstacle
is to your vehicle.
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 30 cm (1 ft) from
the front or rear of the vehicle, the tone will
become constant and the active sensor's field
closest to the vehicle symbol will be filled in.
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 •
Acoustic warnings are only given for
objects directly in front of 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.

Park Assist may not be able to detect all condi-
tions in all situations and functionality may there-
fore be limited in certain cases.
The driver should be aware of the following limi-
tations for Park Assist:
WARNING Be extra cautious when
reversing if this symbol is
shown when a trailer, bike
carrier or similar is attached
and electrically connected
to the vehicle.
The symbol indicates that
the rear parking assist sensors are deacti-
vated and will not warn of any obstacles.

CAUTION Objects such as chains, thin and glossy poles
or low obstacles may end up in the "signal
shadow" and then go temporarily undetected
by the sensors – the pulsating tone may then
unexpectedly stop instead of becoming a
constant tone as expected.
The sensors cannot detect high objects, such
as protruding ramps.
• In such situations, pay extra attention and
maneuver/drive the vehicle very slowly or
stop the current parking maneuver –
there may be a high risk of damage to
the vehicle or other objects since infor-
mation from the sensors is not always
reliable in such situations.
CAUTION In some circumstances, the Park Assist Sys-
tem may produce false warnings due to exter-
nal sound sources with the same ultrasonic
frequencies as those the system works with.
Examples of such sources are horns, wet tires
on asphalt, pneumatic brakes, exhaust noise
from motorcycles, etc.
NOTE When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch pro-
trusion is included when the function meas-
ures the distance to objects behind the vehi-
cle.
