The automatic headlamp feature is only an

aid. The driver is responsible for the vehicle

lighting at all times.

The daytime driving lights improve the detect-

ability of your vehicle during the day. To do

this, the daytime driving lights function must

be switched on via the on-board computer

(Y page 251).

When the side lamps and dipped-beam head-

lamps are switched on, the green T (side

lamps) and L (dipped-beam headlamps)

indicator lamps in the instrument cluster light

up.

! If the battery has been excessively dis-

charged, the side lamps or parking lamps

are automatically switched off to enable

the next engine start. Always park your

vehicle safely and sufficiently lit according

to legal standards. Avoid the continuous

use of the T side lamps for several

hours. If possible, switch on the X right

or the W left parking lamp.

To switch on: turn the light switch to T.

^XTo switch on the dipped beam head-

lamps: turn the key to position 2 in the

ignition lock or start the engine.

Switching on the parking lamps ensures that

the corresponding side of the vehicle is illu-

minated.

Hazard warning lamps

You can use this function to set the head-

lamps to change between dipped beam and

main beam automatically. The system recog-

nises vehicles with their lights on, either

approaching from the opposite direction or

travelling in front of your vehicle, and conse-

quently switches the headlamps from main

beam to dipped beam.

The system automatically adapts the dipped-

beam headlamp range depending on the dis-

tance to the other vehicle. Once the system

no longer detects any other vehicles, it

Important safety notes

If you are driving at speeds above approx-

imately 55 km/h and no other road users

are detected:

The main-beam headlamps are switched on

automatically. The K indicator lamp in

the instrument cluster also lights up.

If you are driving at speeds below approx-

imately 45 km/h or other road users are

detected or the roads are adequately lit:

remains lit.

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

In very rare cases, Adaptive Highbeam Assist

recognises road users too late or not at all. In

this, or in similar situations, the automatic

main-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 main-beam headlamps in

good time.

To deactivate: move the combination

switch back to its normal position.

The _ indicator lamp in the multifunc-

tion display goes out.

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 conditions.

Headlamps misted up on the inside

Certain climatic and physical conditions may

cause moisture to form in the headlamp. This

moisture does not affect the functionality of

the headlamp.

In particular, the detection of obstacles can

be restricted if there is:
