MODEL ALL (CAR) with CODE 218 (Rear view camera) 

MODEL ALL (CAR) with CODE P44 (Parking package) 

Overview 

This document contains the following information:

• General 
• Function requirements 
• Reversing camera picture display 
• Functional restrictions 

General 

The reversing camera allows the driver to view the area behind the vehicle as a live picture. He can choose between various displays. The view shown on the reversing camera display is prepared with guide lines. The function is operated using the multimedia system.

Function requirements 

• Terminal 15 ON
• Trunk lid or liftgate closed
• No trailer operation (vehicles with trailer hitch)

Reversing camera picture display 

The reversing camera tasks include recording the area surrounding the vehicle at the rear and the generation of dynamic and static guide lines. The pictures recorded by the reversing camera using an extended angle of vision of 180° are processed accordingly by the integrated control unit. The current driving path is shown on the multimedia system in the form of guide lines based on the vehicle dimensions, vehicle speed and steering wheel angle.

If the trunk lid or liftgate is not closed, the picture on the multimedia system is overlaid with a warning message. The guide lines are hidden from view.

On initial startup and after being replaced, the reversing camera must be recoded using the diagnostic tester. The reversing camera is calibrated automatically after initial startup.

When reverse gear is engaged (vehicles with manual transmission) or drive range R is engaged (vehicles with automatic transmission), the reversing camera is activated. The reversing camera evaluates the input parameters and starts recording the surrounding area.

The reversing camera stops recording the surrounding area under the following conditions:

• Vehicle speed during forward travel higher than 12 km/h
• Driving distance during forward travel higher than 10 m
• Time period more than 255 s with reverse gear not engaged (vehicles with manual transmission) o drive range "R" not engaged (vehicles with automatic transmission)
• Drive range "P" engaged (vehicles with automatic transmission)
• Circuit 15 OFF

The picture data from the reversing camera are processed by the multimedia system and shown on the multimedia display.

The reversing camera uses the steering wheel angle and stored vehicle parameters (lane and exterior contour of the vehicle) to calculate guide lines which are superimposed on the display. The steering angle is recorded by the steering wheel angle sensor.

The following displays can be selected:

• Normal view
• Wide angle view
• Trailer view (vehicles with trailer hitch)

The area behind the vehicle is displayed mirror-inverted, as it is in the inside rearview mirror.

Normal view 

Wide angle view 

The wide angle view assists the driver when reversing in unclear traffic areas. The reversing area is shown as a three-part view with an angle of 180°. This gives the driver a clear view of crossing roads in good time, e.g. when reversing out of narrow streets.

Trailer view (vehicles with trailer hitch) 

All guide lines are hidden during an attempted correction (forward travel). When reverse gear is engaged again (vehicles with manual transmission) or when drive range R is engaged (vehicles with automatic transmission) the guide lines are shown again taking the following parameters into account:

• Time period less than 255 s
• Vehicle speed below 10 km/h
• Driving distance below 10 m at forward travel

The picture displayed disappears when these parameters are exceeded. The reversing camera then remains in standby mode.

Functional restrictions 

The reversing camera does not operate in the following situations or does so to a limited extent only:

• Trunk lid/liftgate open
• Heavy rain, snow or fog
• Darkness
• Reversing camera is exposed to extremely bright light
• Area illuminated by fluorescent lamps or LEDs (display flicker)
• Fast temperature change, e.g. driving through heated garage in winter
• Camera lens is dirty or covered up

Additional vehicle attachments mounted at the rear, e.g. license plate bracket or rear bicycle carrier, may also restrict the viewing range and other functions of the reversing camera.
