Active Parking Assist
Function of Active Parking Assist
Active Parking Assist is an electronic parking
assistance system which uses ultrasound and is
automatically activated during forward travel.
The system is operational at speeds below
approximately 35 km/h.
When all the conditions are fulfilled, the follow‐
ing symbol appears in the multifunction display
in the instrument cluster:
The system then independently locates and
measures parallel and perpendicular parking
spaces on both sides of the vehicle.
When Active Parking Assist has detected parking
spaces, the following symbol appears in the mul‐
tifunction display in the instrument cluster:
The arrows show on which side of the carriage‐
way free parking spaces are located. They are
then shown in the multimedia system display.
The parking space and, if necessary, the parking
direction can be selected as desired. Active
Parking Assist calculates a suitable vehicle path
and assists you in parking and exiting the park‐
ing space.
Vehicles with automatic transmission: Active
Parking Assist supports with changing gear,
accelerating, braking and steering the vehicle.
Vehicles with manual transmission: the active
brake application and automatic gear change are
only available on vehicles with automatic trans‐
mission. You must therefore brake the vehicle
and change gear yourself when parking or exit‐
ing a parking space.
Active Parking Assist is only an aid. It is not a
substitute for your attention to the surroundings.
The responsibility for safe manoeuvring and
parking remains with you. Make sure that no
persons, animals or objects etc. are in the
manoeuvring range.

other things, one of the following actions is car‐
ried out:

System limitations
Objects located above or below the detection
range of Active Parking Assist are not detected
when the parking space is being measured.
These are also not taken into account when the
parking manoeuvre is calculated, e.g. overhang‐
ing loads, overhangs or loading ramps of lorries
or the boundaries of parking spaces. In some cir‐
cumstances, Active Parking Assist may therefore
guide you into the parking space prematurely.
