Exterior lights (R50)

Exterior lights

Function

The exterior lights, the headlight adjustment and the fog lamps are controlled via the central body electrical system; the reversing lights are controlled directly via the switch for reversing lights.

Headlights

To switch on the parking lights, the main light switch must be set to position 1.

To switch on the dipped beam, the main light switch must be set to position 2/dipped beam and the ignition switch to position 2.

To operate the headlight flasher, the dipped beam/full beam switch and/or headlight flasher lever must be pulled towards the driver and the ignition key must be in position 1 or 2.

To switch on the full beam, the dipped beam/full beam switch must be pulled toward the driver until it reaches its end position. The ignition key must be in position 2 and the main light switch in position 2. The full beam is deactivated by pulling the dipped beam/full beam switch a second time towards the driver. Turning the ignition key either to position 0 or 1 also switches off the full beam.

To switch on the additional headlights (if fitted), the headlight flasher must be operated as described above.

To switch on the fog lamps, the main light switch must be set to either position 1 or position 2/dipped beam. The ignition switch must be in position 2 and the switch for the fog lamps must be pressed. The fog lamps can be switched off by again pressing the appropriate switch or by turning the ignition switch to 0 or 1.

Rear lights

To switch on the rear lights and the licence plate light, the main light switch must be set to either position 1 or position 2. The ignition key can be in any switch position.

The brake lights are activated when the brake pedal is pressed and the ignition key is in position 1 or 2.

To switch on the rear fog lamps, the main light switch must be set to position 2/dipped beam and the ignition switch to position 2. Then the rear fog lamps switch must be pressed. To switch off the rear fog lamps, the rear fog lamp switch must be pressed again or the ignition key moved to position 0 or 1. Alternatively, the main light switch can be moved to position 1 or 0/OFF.

European daytime-driving light

This option can be programmed.

When the ignition switch is in position 2 and the main light switch is in position 0/OFF, the dipped beam, parking light, rear and licence plate lights are switched on.

Canadian daytime-driving light

This option can be programmed.

When the ignition switch is in position 2 and the main light switch is in position 0/OFF, the headlights are switched on with reduced power. When the parking brake is operated or the selector lever setting PARK is selected, the daytime-driving light is switched off.

Dipped beam with wiper

This option can be programmed.

When the ignition switch is in position 2 and the main light switch is switched off, the dipped beam and parking light can be switched on by operating the wiper.

Warning lamps and turn indicators

To switch on the turn indicators, the ignition switch must be in position 1 or 2 before the turn indicator stalk is operated.

Home lighting (automatic headlight deactivation)

This option can be programmed.

To activate the automatic headlight deactivation, the initial state is that the ignition switch is at position 2 and the main light switch is at position 2. Then, switching off the lights after switching off the ignition activates the timer function (if this is done in reverse order, the light switches off as normal). The dipped beam remains on for approx. 30 seconds and then switches off automatically.

Headlight adjustment

The headlights can be adjusted vertically by turning headlight setting wheel. The ignition switch must be in position 2 and the main light switch at either position 1 or 2/dipped beam.

On vehicles with gas discharge headlights, the headlight adjustment is performed using a separate control unit.
