System functions
The following BMW Night Vision system functions are described:
- Power supply and ground
- Heating for protective glass on the night-vision camera
- Cleaning the protective glass on the night-vision camera
- Zoom function
- Panning image section
- Function limitations
Power supply and ground
- E60, E61, E63, E64
The rear power distributor supplies the night-vision electronics with terminal 30g.
- E65, E66
The front power distributor supplies the night-vision electronics with terminal 30.
The night-vision camera, including the heating, receives its power from the night-vision electronics.
The night-vision electronics and the night-vision camera share a common ground point. This reduces the system's susceptibility to malfunctions.
Heating for protective glass on the night-vision camera
To prevent the protective glass from misting or freezing over, a heating element is installed in the housing of the night-vision camera. The heating is switched on under the following conditions:
- Ambient temperature between 5 °C and -15 °C
Cleaning the protective glass on the night-vision camera
The night-vision camera is equipped with a cleaning system.
The washer jet is bolted to the night-vision camera with a bracket. The washer jet is connected to the headlamp cleaning system. The cleaning of the protective glass is actuated together with the headlamp cleaning system.
Zoom function
The zoom function can be selected as needed. To do this, select "Zoom" in the BMW Night Vision menu.
The zoom is calculated by the night-vision camera. The zoom function can only be selected when the "Full image" display is not selected.
When zoom is active, the display is automatically enlarged 1.5 -fold at speeds of 70 km/h upwards. Here, the viewing angle of the night-vision camera is reduced from 36° to 24°.
Zoom is automatically deactivated when the vehicle's speed drops below 60 km/h. The viewing angle of the night-vision camera is restored to 36°.
(zoom IN over 70 km/h and zoom OUT under 60 km/h: currently only encoded for Europe version)
Panning image section
The image section can be panned when "Cornering mode" is selected in the BMW Night Vision menu. "Cornering mode" is only executed when zoom is activated.
The image section then follows the vehicle's path through a bend (signals: steering angle, yaw rate).
The night-vision camera calculates the panning angle needed for the image section.
"Cornering mode" can only be selected when the "Full screen" display is not selected.
Function limitations

It is not possible to run the following simultaneously:
