110 Interior lighting Cornering light function Interior lighting Overview of interior lighting The cornering light function improves the illumination of the road over a wide angle in the direction you are turning, enabling better visibility in tight bends, for example. It can only be activated when the low-beam headlamps are switched on. Active: if you are driving at speeds below 25 mph (40 km/h) and switch on the turn signals or turn the steering wheel. Not active: if you are driving at speeds above 25 mph (40 km/h) or switch off the turn signal or turn the steering wheel to the straight-ahead position. The cornering light function may remain lit for a short time, but is automatically switched off after no more than three minutes.
