Active Parking Assist is an electronic parking assistance system that automatically searches for and measures parking spaces on both sides of the vehicle when travelling forwards up to approx. 35 km/h.
Active Parking Assist provides assistance when changing gear, accelerating, braking and steering the vehicle.
If all requirements are met, the 
display appears in the multifunction display. 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 
display appears in the multifunction display. The arrows show on which side of the road detected parking spaces are located. They are then shown in the media display. The parking space and, if necessary, the parking direction can be selected as desired. Active Parking Assist calculates a suitable vehicle path, switches on the turn signal indicator and assists you in parking and exiting the 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.
Parking Assist PARKTRONIC is deactivated.
You begin steering.
You apply the parking brake.
You engage transmission position
. ESP® intervenes.
You open the doors or the tailgate while driving.
Objects located above or below the detection range of the sensors, e.g. overhanging loads, tail sections or loading ramps of goods vehicles, or the borders of parking spaces, are not detected during measurement of the parking space. These are also then not taken into account when calculating the parking procedure. In some circumstances, Active Parking Assist may therefore guide you into the parking space incorrectly.
Active Parking Assist may steer too early.
The vehicle may not stop in front of these objects.
This could cause a collision.
Extreme environmental conditions, such as snowfall or heavy rain, may lead to a parking space being measured inaccurately. Parking spaces that are partially occupied by trailer drawbars might not be identified as such or be measured incorrectly. Only use Active Parking Assist on level, high-grip ground.
In extreme weather conditions such as ice, packed snow or in heavy rain.
When transporting a load that protrudes beyond the vehicle.
If the parking space is on a steep downhill or uphill gradient.
When snow chains are fitted.
When a trailer or bicycle rack is attached.
Directly after a tyre change or when spare tyres are fitted.
If the tyre pressure is too low or too high.
If the suspension is out of alignment, e.g. after bottoming out on a kerb.
On steep inclines of more than approx. 15%.
Parking spaces where parking is prohibited.
Parking spaces on unsuitable surfaces.
