Automatic dynamic headlight range control
Your vehicle is equipped with a headlight range control to prevent oncoming traffic from being dazzled when the vehicle is heavily laden. The headlight beam settings are adjusted automatically (even during braking and acceleration).
Light functions
The following light functions depend on which equipment is fitted in your vehicle and work only when the light switch is set to AUTO.
Static cornering light (turning light)* - The turning light is automatically activated when the steering wheel angle exceeds a specified value (up to about 70 km/h) or when the turn signals are switched on (up to about 40 km/h). This feature provides better illumination at the side of the vehicle when you turn off at a junction.
Motorway light* - The motorway light adjusts the main beams on motorways according to the vehicle's speed.
Speed-dependent light distribution* - The speed-dependent light distribution adjusts the vehicle lighting as required on motorways and other main roads. Intersections can also be illuminated if your vehicle is equipped with a navigation system*.
- The automatic headlights are only intended to assist the driver. The driver must always ensure that the headlights are used when required, and may have to switch them on manually when the light conditions or visibility are poor. For example, the light sensors are not able to detect fog. Therefore, you should always switch on the dipped headlights in these conditions and when driving after dark.
- To avoid dazzling the traffic behind you, the rear fog light should only be used in accordance with statutory regulations.
- Observe all relevant statutory requirements when using the lighting systems described here.
Note
- The light sensor for the automatic headlights is located in the mounting for the interior mirror. Do not affix any stickers on this section of the windscreen.
- Some of the settings for the exterior lighting can be adjusted ►Link.
- A buzzer will sound if you switch off the ignition and open the door when the exterior lighting is on.
- On vehicles for some markets, the rear lights remain off when the daytime running lights are switched on.
- In cool or damp weather, the inside of the headlights, turn signals or rear lights can sometimes mist up, due to the temperature difference between the interior and exterior of the car. They should clear again partially or completely soon after you switch on the headlights. This phenomenon has no influence on the life expectancy of the vehicle lights.
