Exterior lighting

Important safety notes

For reasons of safety, Mercedes-Benz recommends that you drive with the lights switched on even during the daytime. In some countries, operation of the headlamps varies due to legal requirements and self-imposed obligations.

Information about driving abroad

Converting to symmetrical low beam when driving abroad: switch the headlamps to symmetrical low beam in countries in which traffic drives on the opposite side of the road to the country where the vehicle is registered. This prevents glare to oncoming traffic. Symmetrical lights do not illuminate as large an area of the edge of the road.

Have the headlamps converted at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center, as close to the border as possible before driving in these countries.

Converting to asymmetrical low beam after returning: have the headlamps converted back to asymmetrical low beam at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center, as soon as possible after crossing the border again.

Adaptive Highbeam Assist

You can use this function to set the headlamps to change between low beam and high beam automatically. The system recognizes vehicles with their lights on, either approaching from the opposite direction or traveling in front of your vehicle, and consequently switches the headlamps from high beam to low beam.

The system automatically adapts the lowbeam headlamp range depending on the distance to the other vehicle. Once the system no longer detects any other vehicles, it reactivates the high-beam headlamps.

The system's optical sensor is located behind the windshield near the overhead control panel.

- To activate: activate the Adaptive Highbeam Assist function using the onboard computer.

- Turn the light switch to or
.

- Press the combination switch beyond the pressure point in the direction of arrow 1.

If it is dark and the light sensor activates the low-beam headlamps, the
indicator lamp in the instrument cluster lights up.

If you drive faster than approximately 28 mph (45 km/h):
the headlamp range is set automatically depending on the distance between the vehicle and other road users.

If you drive faster than approximately 35 mph (55 km/h) and no other road users are identified:
the high-beam headlamps are switched on automatically. The indicator lamp
in the instrument cluster also lights up.

When you drive slower than approximately 30 mph (45 km/h) or if other road users are identified or if the roads are sufficiently illuminated:
the high-beam headlamps are switched off automatically. The indicator lamp
in the instrument cluster goes out. The
indicator lamp in the instrument cluster stays on.

- To deactivate: move the combination switch back to its normal position.

The indicator lamp in the
instrument cluster goes out.

WARNING
The Adaptive Highbeam Assist is only an aid intended to support you while driving. The driver is and remains responsible for proper vehicle lighting in accordance with the prevailing light, sight and traffic conditions.

The system may be impaired or unavailable when
- visibility is poor, e.g. due to snow, rain, fog, or heavy spray
- the optical sensor area of the windshield is dirty, fogged up, or covered by a sticker for example
The system cannot recognize the following road users:
- Road users without a lighting system of their own, e.g. pedestrians - Road users with dim lighting of their own, e.g. cyclists
- Road users whose lighting is obstructed, e.g. road users behind a guardrail - In some seldom cases, even road users with a lighting system of their own may be recognized too late or not at all.

The automatic high-beam headlamps will then not be deactivated or it will be activated in spite of preceding or oncoming road users.

This could endanger you and/or others and cause an accident. Always pay close attention to the traffic situation and switch off the high beam manually if necessary.

Headlamps fogged up on the inside

The headlamps may fog up on the inside if there is high atmospheric humidity.

- Drive with the headlamps switched on.

The level of moisture diminishes, depending on the length of the journey and the weather conditions (humidity and temperature).

If the level of moisture does not diminish: - Have the headlamps checked at a qualified specialist workshop.
