Exterior lighting

General notes

For reasons of safety, Mercedes-Benz recom-

mends 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.

Driving abroad

Symmetrical dipped beam

It is not necessary to switch your headlamps to

symmetrical dipped beam when driving in coun-

tries where vehicles are driven on the opposite

side of the road to the country in which the vehi-

cle is registered. Legal requirements are fulfilled

without switching the headlamps to symmetri-

cal dipped beam.

Adaptive Highbeam Assist

General notes

You can use this function to set the headlamps

to switch automatically between dipped beam

and main beam. The system recognises vehicles

with their lights on, either approaching from the

opposite direction or travelling in front of your

vehicle, and consequently switches the head-

lamps from main beam to dipped beam. Once

the system no longer detects any other vehicles,

it switches on the main-beam headlamps again.

The system's optical sensor is located behind

the windscreen near the overhead control

panel.

Important safety notes

WARNING

Adaptive Highbeam Assist does not recognise

road users:

who have no lights, e.g. pedestrians

who have poor lighting, e.g. cyclists

whose lighting is blocked, e.g. by a barrier

On very rare occasions, Adaptive Highbeam

Assist may fail to recognise other road users

that have lights, or may recognise them too

late. In this, or in similar situations, the auto-

matic main-beam headlamps will not be deac-

tivated or will be activated despite the pres-

ence of other road users. There is a risk of an

accident.

Always carefully observe the traffic conditions

and switch off the main-beam headlamps in

good time.

Adaptive Highbeam Assist cannot take into

account road, weather or traffic conditions.

Adaptive Highbeam Assist is only an aid. You are

responsible for adjusting the vehicle's lighting

to the prevailing light, visibility and traffic con-

ditions.

In particular, the detection of obstacles can be

restricted if there is:

poor visibility, e.g. due to fog, heavy rain or

snow

dirt on the sensors or if the sensors are

obscured

Switching Adaptive Highbeam Assist
