pact pr otection
ection
Pa ssive side impact pr otection is an additional
Pa rking Assist PARKTRONIC function which warns
th e driver about obstacles at the side of theve hi-
cle. A warning is issued when obstacles are
de tected between the front and rear de tection
ra nge. In order for an object on the side tobe
de tected, the sensors in the front and rear
bumper must /rst de tect the object while you are
driving past it.
During the parking procedure or manoeuvring,
objects are de tected as theve hicle drives past. If
yo u steer in the direction of a de tected obs tacle
and there is a risk of a lateral collision, a warning is issued and
the segments light up in colour in
th e displa y.
The segment colour changes depending on the
distance tothe de tected obs tacle:
R Y
Y ellow ellow :
:appr oximately 30 - 60 cm
R R
Red:
ed: less than appr oximately 30 cm
In order for lateral, front or rear segments tobe
displa yed, theve hicle must /rst tr avel a distance
of at least half a vehicle's length. Once theve hicle
has tr avelled the length of theve hicle, all of the
lateral front and rear segments can be displ ayed. 270

Driving and parking

As soon as all
requ irements are met for sear ching
fo r parking spaces, theÇ display appears in
th e Instrument Displa y.
When Active Parking Assist has de tected parking
spaces, theÈ display appears in the Instru-
ment Displa y.The ar rows show on which side of
th ero ad de tected parking spaces are located.
They are then shown in the media displa y.
The parking space can be selected as desired.
Depending on the location of the parking space,
th e parking direction (rear wards or forw ards) can
also be selected as desired.
When Active Parking Assist is activated, the turn
signal indicators are activated based on the calcu-
lated path of your vehicle.
When you are entering or exiting a parking space,
th e procedure is assisted byacceleration, braking,
steering and gear changes.

stitute foryo ur attention tothe sur roundings. The
re sponsibility for safe manoeuvring and parking
re mains with you. Make sure that no persons, ani-
mals or objects etc. are in the manoeuvring
ra nge.

lating the parking procedure. In some circumstan-
ces, Active Parking Assist may therefore guide
