Useful information

i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Read the information on qualified specialist workshops: (Y page 27).

Exterior lighting General 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.

Driving abroad Conversion to symmetrical low beam Switch the headlamps to symmetrical low beam in countries in which traffic drives on the opposite side of the road from the country where the vehicle is registered. This prevents glare to oncoming traffic. When using symmetrical lights, the edge of the road is not lit as widely and as far ahead as normal. Have the headlamps converted at a qualified specialist workshop as close to the border as possible before driving in these countries.

Conversion to asymmetrical low beam after returning Have the headlamps converted back to asymmetrical low-beam headlamps at a qualified specialist workshop as soon as possible after crossing the border again.

Setting the exterior lighting Setting options Exterior lighting can be set using: Rthe light switch Rthe combination switch (Y page 123) Rthe on-board computer (Y page 274)

Active light function

Exterior lighting 125

Cornering light function

The cornering light function improves the illumination of the road over a wide angle in the direction you are turning, enabling better visibility in tight bends, for example. It can only be activated when the low-beam headlamps are switched on. Active: Rif you are driving at speeds below

25mph (40 km/h) and switch on the turn signal or turn the steering wheel

Rif you are driving at speeds between

25mph (40 km/h) and45mph (70 km/h) and turn the steering wheel

Not active: if your speed exceeds 25mph (40 km/h) or if you switch off the turn signal or turn the steering wheel to the straight-ahead position. The cornering light function may remain lit for a short time, but is automatically switched off after no more than three minutes.

The active light function is a system that moves the headlamps according to the steering movements of the front wheels. In this way, relevant areas remain illuminated while driving. This allows you to recognize pedestrians, cyclists and animals. Active: when the lights are switched on.

Adaptive Highbeam Assist Important safety notes G WARNING Adaptive Highbeam Assist does not recognize road users: Rwho have no lights, e.g. pedestrians Rwho have poor lighting, e.g. cyclists Rwhose lighting is blocked, e.g. by a barrier

126 Exterior lighting

In very rare cases, Adaptive Highbeam Assist may fail too recognize other road users that have lights, or may recognize them too late. In this or similar situations, the automatic high-beam headlamps will not be deactivated or activated regardless. There is a risk of an accident. Always carefully observe the traffic conditions and switch off the high-beam headlamps in good time.

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 low- beam 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.

Switching Adaptive Highbeam Assist on/off
