MODEL 221.0 /1, 216.3 with CODE (218) Backup camera with CODE (498) Japan version as of Model Year 2009 /AEJ 08
Reversing camera (RFK), general operating notes
The reversing camera system enables the driver to select between two parking modes:
- Reverse parking
- Parallel parking
When reverse gear is engaged, the parking mode last selected is activated.
The driver can switch between reverse parking mode and parallel parking mode via the front central operating unit (A40/9).
The operating notes for the reversing camera comprise the following notes:
- Parallel parking, operating information
- Reverse parking, operating information
The "reverse parking" mode does not provide any instructions for the parking procedure, i.e. the displayed guide lines provide only a visual representation of the driving corridor.
Parallel parking, operating information
The operating information for parallel parking consists of the following operating notes:
- Move to start position
- Determining final parking position
- Transition from first to second steering angle
Move to start position
The optimum start position is located at s = 1 m parallel to the vehicle in front of the free parking space.
Furthermore the driver seat of the vehicle parking in front should be at the level of the rear axle of the vehicle you are driving.
The two vertical guide lines should line up with the rear of the vehicle parked in front.
If this is not the case, the driver must first reset straight ahead until one of the guide lines touches the end of the vehicle rear.
Determining final parking position
Once the start position for parking is defined, then the desired parking position must be set. For this purpose the driver with the vehicle at a standstill must firstly turn in the steering wheel.
The COMAND display (A40/8) now shows a parking frame (here shown in blue) with which the driver must define the target position. This parking frame turns in ratio to the steering angle, i.e. with the aid of the steering wheel the driver can define the position of the parking frame and thus the final parking position. The driver can also use the parking frame to determine whether the parking space is suitable for his/her vehicle.
Once the driver has defined the parking position with the aid of the parking frame, the reversing camera control unit (N66/2) then uses the collated data to define the parking position and the required steering angle for the subsequent first steering angle.
The color of the parking frame must be blue, if the parking space is to be successfully entered with the set steering angle. If the parking frame is colored red, then the steering angle must be continually adapted until the parking frame turns blue.
Transition from first to second steering angle
First steering angle:
Once the parking position has been defined, the driver moves the vehicle backwards. During this phase the driver must maintain the previously defined steering angle. As soon as the vehicle approaches the edge of the road, a guide line appears in the COMAND display. This guide line can be used by the driver to determine when he/she should initiate the next steering maneuver. As soon as the guide line virtually touches the edge of the road, the driver stops the vehicle and turns the steering wheel up to the limit stop in the opposite direction.
To prevent the driver relying solely on the COMAND display and as a result ignoring the immediate environment, no help lines are displayed in the parking space during the first steering maneuver.
Second steering angle:
As soon as the steering wheel is at its limit stop, the same distance lines as those for reverse parking appear in the COMAND display.
These lines can be used by the driver to maneuver the vehicle such that the best parking position is achieved.
Operating instructions for reverse parking
The guide lines are only intended as a visual representation of the driving corridor, i.e. the reverse parking mode does not provide any instructions for the parking procedure.
The operating information for reverse parking consists of the following operating notes:
- Display of guide lines
- Parking procedure
- Display of distance lines
Display of guide lines
Virtual extension of vehicle's longitudinal axis (blue guide lines):
The blue guide lines represent a virtual extension of the vehicle. The distance between the blue guide lines is slightly greater than the vehicle width.
Virtual steering angle (yellow guide lines):
The yellow guide lines are shown as soon as the driver turns the steering wheel. They indicate to the driver the path which the vehicle would follow with the currently applied steering angle. This curve is automatically adapted to the situation as the steering angle changes. The distance between the yellow guide lines is slightly more than the vehicle width.
Parking procedure
In order to park, the driver must now adjust the steering angle until an outer line of the yellow guide lines in the COMAND display virtually touches the parking space marking.
This parking space marking can, e.g. be another vehicle or a line on the asphalt. The driver must then continue reversing and adapting the steering angle until the displayed parking space limits run parallel to the current direction of travel.
Next the driver must turn the steering wheel back into the straight-ahead position in order to drive in a straight line up to the final parking position in the parking lot.
Display of distance lines
In the straight-ahead position of the steering (steering angle = 0°) the yellow guide lines are congruent with the blue guide lines.
As soon as the lines are congruent, the blue guide lines are no longer displayed.
By means of distance lines the driver is informed about the distances from the virtual bumper to the obstacles.
No acoustic information and warning messages are given during reverse parking.
