Low beams
When driving with the lighting ring in the 
position, low beam will be automatically activated in weak daylight or dark conditions, or when the vehicle is in drive mode.
With the lighting ring in the position, the low beams will also be automatically activated if the rear fog light is activated.
With the lighting ring in the 
position, low beams will always be on when the vehicle is in drive mode.
Tunnel detection
The vehicle will detect if it enters a tunnel and shift from daytime running lights to low beams.
Note that the left-hand steering wheel lever must be in position for tunnel detection to work.
