Active Parking Assist is an electronic parking assistance system, which uses ultrasound with the assistance of the reversing camera and 360° Camera. When you are driving forwards up to approximately 35 km/h, the system automatically measures parking spaces on both sides of the vehicle.
Country-dependent: parking in parking spaces parallel to the road
Parking in parking spaces perpendicular to the road (optionally either forwards or reverse)
Exiting parking spaces if you have parked using Active Parking Assist
As soon as all requirements are met for searching for parking spaces, the 
display appears in the multifunction display.
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 can be selected as desired. Depending on the location of the parking space, the parking direction (rearwards or forwards) can also be selected as desired.
When Active Parking Assist is activated, the turn signal indicators are activated based on the calculated path of your vehicle.
When you are entering or exiting a parking space, the procedure is assisted by acceleration, braking, steering and gear changes.
Vehicles with manual transmission: the active brake application and automatic gear change are only available on vehicles with automatic transmission. You must therefore brake the vehicle and change gear yourself when parking or exiting 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.
Parking Assist PARKTRONIC is deactivated.
You begin steering.
You apply the parking brake.
Vehicles with automatic transmission: you engage transmission position
. ESP® intervenes.
You open the doors or the boot lid while driving.
If the exterior lighting is malfunctioning, Active Parking Assist is not available.
Objects located above or below the detection range of the sensors, e.g. overhanging loads, overhangs 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 weather conditions, such as snow 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.
On steep uphill or downhill gradients of more than approximately 15%.
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.
Parking spaces where parking is prohibited.
Parking spaces on unsuitable surfaces.
