Mercedes-Benz C-Class Owners Manual: 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 22 mph (35 km/h).

When all the conditions are fulfilled, the following 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 multifunction display in the instrument cluster:

The arrows show on which side of the roadway 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 parking space.

Vehicles with automatic transmission: Active Parking Assist supports with changing gear, accelerating, braking and steering the vehicle.

Active Parking Assist is only an aid. It is not a substitute for your attention to the surroundings.

The responsibility for safe maneuvering and parking remains with you. Make sure that no persons, animals or objects etc. are in the maneuvering range.

Active Parking Assist is canceled if, among other things, one of the following actions is carried out:

  • You deactivate Parking Assist PARKTRONIC.

  • You deactivate Active Parking Assist.

  • You begin steering.

  • You apply the parking brake.

  • Vehicles with automatic transmission: You engage transmission position P.

  • ESP intervenes.

  • You open the doors or the trunk lid while driving.

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 maneuver is calculated, e.g. overhanging loads, overhangs or loading ramps of trucks or the boundaries of parking spaces. In some circumstances, Active Parking Assist may therefore guide you into the parking space prematurely.

WARNING Risk of accident due to objects located above or below the detection range of Active Parking Assist
If there are objects above or below the detection range, the following situations may arise:
  • Active Parking Assist may steer too early.
  • Vehicles with automatic transmission: The vehicle may not stop in front of these objects.

This could cause a collision.

  • In these situations, do not use Active Parking Assist.

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.

Do not use Active Parking Assist in the following situations:

  • 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 installed.

Active Parking Assist may also display parking spaces that are not suitable for parking, e.g.:

  • Parking spaces where parking is prohibited.
  • Parking spaces on unsuitable surfaces.

Active Parking Assist will not assist you with parking spaces at right angles to the direction of travel in the following situations:

  • If two parking spaces are located immediately next to each other.
  • If the parking space is immediately next to a low obstacle such as a curb.

Active Parking Assist will not assist you with parking spaces parallel or at right angles to the direction of travel in the following situations:

  • If the parking space is on a curb.
  • If the parking space is bordered by an obstacle, e.g. a tree, a post or a trailer.

Parking with Active Parking Assist

  • Select desired parking space 4.
  • Where necessary, select the parking direction: forwards or reverse.

    Vehicle path 3 is shown, depending on selected parking space 4 and the parking direction.

    Confirm selected parking space 4.

The turn signal indicator is switched on automatically when the parking procedure begins. The turn signal indicator is switched off automatically when you switch to D.

You are responsible for selecting the turn signal in accordance with the traffic conditions. If necessary, select the turn signal accordingly.

WARNING Risk of accident due to vehicle swinging out while parking or pulling out of a parking space
While parking or exiting a parking space, the vehicle swings out and can drive onto areas of the oncoming lane.

This could cause you to collide with objects or other road users.

  • Pay attention to objects and other road users.
  • Where necessary, stop the vehicle or cancel the parking procedure with Active Parking Assist.
  • If, for example, the Please Engage Reverse Gear message appears in the multimedia system display: select the corresponding transmission position.

    Vehicles with automatic transmission: The vehicle drives into the selected parking space.

On completion of the parking procedure, the Parking Assist Finished, Take Control of Vehicle display message appears. Further maneuvering may still be necessary.

  • After completion of the parking procedure, safeguard the vehicle against rolling away.

    When required by legal requirements or local conditions: turn the wheels towards the curb.

You can stop the vehicle and change the transmission position during the parking procedure.

The system then calculates a new vehicle path. The parking procedure can then be continued. If no new vehicle path is available, the transmission position will be changed again. If the vehicle has not yet reached the parking space, the parking procedure will be canceled, should a gear be changed.

Function of Drive Away Assist

Drive Away Assist can reduce the severity of an impact when pulling away. If an obstacle is detected in the direction of travel, the vehicle's speed is briefly reduced to approx. 1 mph (2 km/h). If a critical situation is detected, the LIM symbol appears on the camera image of the multimedia system.

WARNING Risk of accident caused by limited detection performance of Drive Away Assist
Drive Away Assist cannot always clearly identify objects and traffic situations.

In such cases, Drive Away Assist might:

  • Warn you without reason and limit the vehicle speed.
  • Not warn you or not limit the vehicle speed.
  • Always pay careful attention to the traffic situation; do not rely on Drive Away Assist alone.
  • Be prepared to brake or swerve as necessary, provided the traffic situation permits and that it is safe to take evasive action.

Drive Away Assist is only an aid. It is not a substitute for your attention to the surroundings.

The responsibility for safe maneuvering and parking remains with you. Make sure that no persons, animals or objects etc. are in the maneuvering range.

A risk of a collision may arise in the following situations, for example:

  • If the driver mixes up the accelerator and brake pedals.
  • If the wrong gear is selected.

The Drive Away Assist function is active under the following conditions:

  • If Parking Assist PARKTRONIC is activated.
  • Every time the gear is changed to R or D when the vehicle is at a standstill.
  • If the detected obstacle is less than approx.3.3 ft (1.0 m) away.
  • If the maneuvering assistance function is activated in the multimedia system.
