Low beam/driving light
If the light switch is set to the position , the low beam is switched on automatically in the following situations:
– Driving through tunnels
– Highway driving (with daytime driving lights deactivated)
When the low beam is switched on, the indicator light on the speedometer lights up.
Fog is not recognised.
Highway function in daylight
The driving light is switched on automatically at vehicle speeds of more than approx. 90 mph (140 km/h) in daylight conditions and when daytime driving lights are deactivated.
If you are travelling below a speed of approx. 40 mph (65 km/h), the driving light is switched off after a delay of approx. 4 minutes, if the external lighting conditions permit.
Highway function in darkness
The distribution characteristics of the driving light change when driving in darkness at vehicle speeds of more than approx. 80 mph (130 km/h). The light beam becomes longer and the field of vision increases.
The driving light is switched on automatically after five seconds of continuous wiper operation.
If the wipers have not been used for approx. 4 minutes, the driving light is switched off.
Automatic headlight levelling
When the ignition and low beam are switched on, the level of the headlight beam automatically changes in accordance with the vehicle load. The level of the headlight beam is automatically kept constant during acceleration and braking.
Automatic headlight levelling is also available when the light switch is set to the position (low beam/driving light).
Daytime driving lights
If the light switch is set to position (light off), the daytime driving lights come on automatically when the ignition is switched on.
If the light switch is set to position , the daytime driving lights come on automatically in bright conditions and when the ignition is switched on.
