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".

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.

from oncoming traffic (p. 383) 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.

camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-

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".

.
Park Assist's side sensors are automatically acti-
vated when the engine is started. They are active
at speeds below 10 km/h (6 mph).
The distance monitored is approx. 25 cm (0.8 ft)
out from the sides.
The detection area increases significantly when
the steering angle of the front wheels increases
and depending on the steering wheel position,
obstacles up to approx. 90 cm (3 ft) directly
behind or in front of the vehicle can be detected
(also see “Side sensor fields” in the section “Sen-
sor field from Park Assist for Park Assist Cam-
era”).Related information

Park Assist Camera trajectory lines
The Park Assist Camera uses trajectory lines
and fields on the screen to indicate the vehicle's
position in relation to its immediate surround-
ings. Example
119
of trajectory lines.
The trajectory lines show the anticipated trajec-
tory for the vehicle's outermost dimensions based
on the current position of the steering wheel to help simplify parallel parking, backing into tight
spaces or attaching a trailer.
The lines on the screen are projected as if they
were painted lines on the ground behind the
vehicle and are directly affected by the way in
which the steering wheel is turned. This enables
the driver to see path the vehicle will take, even if
he/she turns the steering wheel.
These lines also indicate the outermost limits that
any object (towbar, rearview mirrors, corners of
the body, etc.) extends out from the vehicle.
NOTE

When reversing with a trailer that is not
electrically connected to the vehicle, the
screen guide lines show the path the
vehicle will take – not the trailer.
The screen does not show guide lines
when a trailer is electrically connected to
the vehicle's electrical system.
Guide lines are not shown when zooming
in.
CAUTION
Bear in mind that when the rearward
camera view is selected, the screen only
shows the area behind the vehicle – pay
attention to the sides and front of the
vehicle when steering while reversing.
The same applies to the reverse – pay
attention to what is happening with the
rear parts of the vehicle when the front
camera view is selected.
Note that the guide lines show the short-
est path – pay extra attention to ensure
that the vehicle sides do not come in
contact with/travel over anything when
steering while driving forward or that the
vehicle front moves toward/over anything
when steering while reversing. 119
