Side lights, driving light and high-beam headlight
The exterior lights can be switched on and off at the lights operating facility.
Side lights
The side lights are activated by turning the light switch in the light control unit to "Position 1". When the side lights are switched on, the following lights are also activated:
- Dim daytime driving lights
- Tail lights on left and right
- Number-plate light on left and right
- Indicator lamp in the instrument cluster
- Left and right side marker light
To use the side lights to make the parked vehicle easier to identify in darkness, the light switch must be turned to "Position 1". When the side lights are switched on, an acoustic signal sounds if the driver's door is opened, while a Check Control message also appears in the instrument panel (KOMBI). Leaving the side lights on can drain the vehicle's battery.
LED principle of side lights
The side lights are activated by supplying white light-emitting diodes with pulse-width-modulated voltage. The LEDs are an element of the lighting ring. The light from the LEDs is fed into two ring-shaped fibre-optic conductors. The fibre-optic conductors allow the light to pass to the outside. The fibre-optic conductors have a lightly rippled surface on the rear side. This ripple effect ensures a homogeneous light distribution of the side lights.

Driving light
The light switch of the operating facility must be rotated to "Position 2" to activate the driving light. When the engine is switched off the side lights remain on, even if the light switch remains in "Position 2". When the driver's door is opened, the side lights are also switched off.
In "Position AUTO" the driving light is activated by the footwell module (FRM) based on information from the rain-light-solar-condensation sensor.
The headlights execute a reference run each time terminal 15 is activated. During the reference run, the adjustment range of the headlight beam throw adjustment and, depending on the equipment, the adaptive headlight are referenced.
High-beam headlight
The high-beam headlight is switched on under the following preconditions:
- "Terminal 15 on"
- Driving light on
- High-beam headlight selected at turn signal/high beam switch or with high-beam assistant activated
The headlight flasher is activated by pulling back the turn signal/high beam switch.
