General
Active Parking Guidance makes it easier to enter and exit a parking space. This involves driverless driving SAE level 2, i.e. control over the vehicle always lies with the driver.
Active Parking Guidance not only finds the parking space, but also takes over the parking procedure. Up to 12 maneuvers are possible here. A view of the surrounding area is maintained via the 360° camera (Marketing designation: Active Parking Assist PARKTRONIC with 360° camera, as at: March 2023).
On vehicles with manual transmission, emergency braking is applied while being assisted in and out of a parking space, if an imminent collision is detected.
On vehicles with automatic transmission, the system takes over driving into and out of the space as well as signaling, steering, starting up, braking, and changing gears.
Active Parking Guidance (automatic parking space entry and exit) is available in different versions depending on the model series and model year.
As of YoM 20/1 (code 801), on model 293, the functional scope of code 235 (Active Parking Assist) in combination with code 8B8 (Reduction of Active Parking Assist (UN R79)) is limited solely to the Parking Assist PARKTRONIC function. Automated parking space entry and exit is not available here.
As of YoM 20/2 (code 051), on models 118/167/177/243/247/257/293 in combination with code 8B6 (Park Assist with transverse function (UN R79)), only the functional scope "Entry/exit in parking spaces perpendicular to roadway" is available.
Models 206/213/214/223/232/236/238/253/254/290/294/295/296/297 are not affected by the modifications or restrictions.
The driver can also be assisted when driving away. The Drive-away Assist can temporarily limit the vehicle speed if, during a gear change when the vehicle is at a standstill, an obstacle is detected in the direction of travel at a distance of less than approx. 1 meter. Possible situations in which this may be helpful include, for example, if the driver confuses the accelerator and brake pedal, sets an incorrect gear, or depresses the accelerator pedal too much. (Marketing designation:
Drive-away Assist system, as at: March 2023).
On uphill gradients, the performance of the Drive-away Assist system is limited. If a transport device, e.g. a trailer or bicycle rack, is attached to the trailer hitch, the Drive-away Assist system is not available when reversing.

On uphill gradients, the performance of the Drive-away Assist system is limited.
If a transport device, e.g. a trailer or bicycle rack, is attached to the trailer hitch, the Drive-away Assist system is not available when reversing.
Function requirements
- Engine in operation or drivetrain operational
- Parking space detected and selected
- Vehicle speed below 10 km/h (vehicles with automatic transmission)
- No trailer detected (vehicles with trailer hitch) (environment monitoring while reversing)
- Vehicle was previously parked automatically (only for exiting parking space)
Function
Support videos that illustrate the various functions can be found in the on-line manuals of the respective model series.
Active Parking Guidance is started by selecting a parking space previously detected by the system.
The system evaluates the following function-relevant parameters for this:
- Drive range (vehicles with automatic transmission)
- Electric power steering, status
- Wheel speeds and wheel rotation direction
- Steering wheel angle
- Status of anti-lock braking system (ABS) and Electronic Stability Program (ESP®)
- Trailer recognition (vehicles with trailer hitch)
Parking
If Active Parking Guidance is started, various driving instructions and messages are displayed to the driver. The turn signal indicator is activated (only during the first maneuver). The driver can now take the hands off the steering wheel.
If the driver does not take their hands off the steering wheel (hands-on detection), the process is canceled.
Active Parking Guidance steers the vehicle into the parking space with targeted steering movements.
The driver must drive and brake themselves in vehicles with manual transmission.
The vehicle can be braked and the direction of travel changed by the driver during the procedure. Active Parking Guidance then calculates a new route. The procedure can then be continued if a possible route is available.
The engine torque is influenced such that the vehicle does not drive faster than 10 km/h (vehicles with manual transmission) or 4 km/h (vehicles with automatic transmission). The driver can reduce speed using the brake pedal.
After a maximum of 12 moves the parking procedure is ended but the driver can take over at any time.
Exiting a parking space
Assisted exiting of a parking space can only be started if the parking space was entered beforehand with the assistance function.
After the driver has started the engine and activated the parking system, the system then asks if an assisted unparking procedure is to be started.
When exiting a parking space that is at an incline or at a right-angle to the direction of travel, the driver can select the direction of travel or start the procedure. The turn signal indicator is activated throughout the entirety of the parking space exit maneuver. The driver can now take the hands off the steering wheel.
Example illustration of what is shown on the central display
Exiting parking spaces that are aligned parallel to the direction of travel:
In order to enable the vehicle to be driven out of the parking space in one straight maneuver, the wheels are straightened up as soon as the vehicle is at a sufficient angle. The process has been completed. The unparking procedure is completed at the latest once the vehicle is at an angle of approx. 45° relative to the start position.
Driving forwards out of parking spaces that are aligned at an incline or at right angle to direction of travel:
When parking, the system stores the angle between the drive-by position past and the target position. When exiting a parking space the hand over takes place at about 10° before reaching the drive-by direction.
Reversing out of parking spaces that are aligned at an incline or right angle to direction of travel:
When parking, the system stores the angle between the drive-by position past and the target position. When exiting a parking space the hand over takes place roughly parallel to the drive-by direction.
Example illustration of what is shown on the central display
After completing the unparking procedure, the driving path shown on the central display changes from green to yellow. The hands-off symbol flashes and a warning tone prompts the driver to take over. The driver is then actively in charge of driving the vehicle again.
Automatic parking service (Valet Parking)
The pre-installation for the automatic parking service (Valet Parking) (code 27U) is only available in combination with the Remote Parking Package (code PBH) for models 214/223/294/295/296/297.
This automatic parking service is only possible if national laws allow for the operation of automated valet services, multi-level car parks are equipped with corresponding technology, and the corresponding Mercedes me connect service has been booked.
With the automatic parking service, the vehicle can park automatically without a driver.
The infrastructure in the multi-level car park (e.g. cameras) takes over the parking process, the detection of people and/or vehicles and the monitoring of the vehicle movement.
Example illustration of automatic parking service
Function sequence:
The driver reserves the parking space in advance.
The driver then parks the vehicle in a special drop-off area (4) in the multi-level car park and starts the parking process (6) via the smartphone app (5).
If parking spaces are available and the driver has booked a space, the driver is informed and can exit the vehicle.
An automatic parking procedure (7) is then carried out with the aid of the infrastructure installed in the multi-level car park.
Mercedes-Benz assumes the responsibility for the automated driving.
In the inverse process, the driver can request their vehicle again via a command in the smartphone app (8) and order it to drive up to the pick-up area (9).
Remote-controlled parking
On vehicles with the "Remote-controlled parking" special equipment (code 503), the vehicle automatically maneuvers into the selected parking space and out again. The user remains in the immediate vicinity and starts, monitors and ends the process from the outside using their smartphone (Marketing designation: Remote Parking Assist, as at: March 2023).
The process of remote-controlled parking is shown in an animation at https://moba.i.mercedes-benz.com/baix/cars/297.1_mbux_premiumplus_2022_a/en_GB/page/highlight.html.
The animation example uses the EQS.
