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:
• Collision avoidance assistance –
Automatic interventionWARNING •
The "Steering assistance at risk of rear-
end 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.

• Steering assistance at risk of collision
(p. 372) Limitations of steering assistance
during collision risks from behind
The function may have limited functionality in
certain situations and not intervene, e.g.:
•
for smaller vehicles such as motorcycles
• if more than half of your vehicle has moved
into the adjacent lane
• on roads/lanes with indistinct or no side lane
markings
• 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.

NOTE
The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit 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".

are located in the rearview mirrors.
The side cameras can show views along each
side of the vehicle.
Related information
• Park Assist Camera* (p. 386) 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
121
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. 120

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.Trajectory lines in 360° view* 360° view with trajectory lines

In the 360° view, trajectory lines are shown
behind, in front of, or to the sides of the vehicle,
depending on the direction of travel.
• When driving forward: Front lines
• When backing up: Side lines and rear lines.
When the front or rear camera is selected, the
trajectory lines will be shown regardless of the
vehicle's direction of travel.
With a side camera selected, the trajectory lines
will only be shown if the vehicle is backing up.Trajectory lines for a towbar* Towbar with trajectory line
