General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. Aparking symbol
indicates asuitable parking space. Active
steering intervention and brake application
can assist you during parking. You may also
use PARKTRONIC (Y page 235).
i The active braking application is only
available on vehicles with automatic trans- mission.
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objectsa re in the manoeuvring range. When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of drivewaysore ntrances and exits
R unsuitable surfaces Driving systems

can take over the steering before the vehicle has exited the parking space completely. This
is useful,f or example when you recognise
that it is already possibletop ull out of the
parking space.

R parking using Active Parking Assist is no
longer possible
R you are driving faster than 10 km/h
R aw heel spins and ESP ®
intervenes or fails.
In such cases the ÷warning lamp lights

Towing atrailer For vehicles with
atrailer tow hitch, the min-
imum length for parking spaces is slightly
increased.
If you have attached atrailer to your vehicle,
you should not use Active Parking Assist.
Once the electrical connection is established between your vehicle and the trailer, Active
Parking Assist is no longer available.
PARKTRONIC is deactivated for the rear area. Reversing camera
General notes Example: Saloon
Reversing camera :is an optical parking
and manoeuvring aid. It shows the area
behind your vehicle with guidelines in the

Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycle sorbicy-
cles
R very widel anes
R narrow lanes
R vehicles not driving in the middle of their
lane
R barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. Example
:Saloon
Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly nextto
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nexttoy our vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be the case if ther eare vehicles at the edge of
their lane nearest your vehicle. Due to the nature of the system:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for aprolonged time
The two radar sensor sfor Blind Spot Assist
are integrated intot he sides of the rear
bumper. Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors.
The sensor smust not be covered, for exam-
ple by cycle rack soroverhanging loads. Fol-
lowing asevere impact or in the event of dam-
age to the bumpers, have the function of the
sensor schecked at aqualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
