Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-mends that you drive with the lights switchedon even during the daytime. In some coun-tries, operation of the headlamps varies due tolegal requirements and self-imposed obliga-tions.

HdRight-hand standing lamps
I`Parking lamps, license plate andinstrument cluster lighting
JWAutomatic headlamp mode, control-led by the light sensor
KXLow-beam/high-beam headlamps

When the engine is running, the vehicle is sta-tionary and in bright ambient light: if you turnthe light switch to the`position, the day-time running lamps and parking lamps switchon.
If the engine is running and you turn the lightswitch toX, the manual settings take prec-edence over the daytime running lamps.
USA only:
The daytime running lamps improve the visibil-ity of your vehicle during the day. To do this,the daytime running lamps function must beswitched on using the on-board computer(Ypage 176).
If the engine is running and you turn the lightswitch to`orX, the manual settingstake precedence over the daytime runninglamps.
Low-beam headlamps
GWARNING
When the light switch is set toX, the
low-beam headlamps may not be switched
on automatically if there is fog, snow or
other causes of poor visibility due to the
weather conditions such as spray. There is a
risk of an accident.
In such situations, turn the light switch to
X.
Even if the light sensor does not detect that itis dark, the parking lamps and low-beam head-lamps switch on when the ignition is switchedon and the light switch is set to theXposi-tion. This is a particularly useful function in theevent of rain and fog.
XTo switch on the low-beam headlamps:turn the SmartKey to positionHin the igni-tion lock or start the engine.
XTurn the light switch toX.The greenXindicator lamp in the instru-ment cluster lights up.
Rear fog lamp
The rear fog lamp improves visibility of yourvehicle for the traffic behind in the event ofthick fog. Please take note of the country-spe-cific regulations for the use of rear fog lamps.
XTo switch on the rear fog lamp:turn theSmartKey to positionHin the ignition lockor start the engine.
XTurn the light switch toXorX.
XPress the^button.The yellow^indicator lamp in the instru-ment cluster lights up.
XTo switch off the rear fog lamp:press the^button.The yellow^indicator lamp in the instru-ment cluster goes out.
Parking lamps
!If the battery charge is very low, the park-ing lamps or standing lamps are automati-cally switched off to enable the next enginestart. Always park your vehicle safely and ina well lit area, in accordance with the rele-vant legal stipulations. Avoid using the`parking lamps over a period of severalhours. If possible, switch on the right-handdor left-handcstanding lamps.
XTo switch on:turn the light switch to`.The green`indicator lamp in the instru-ment cluster lights up.
Standing lamps
Switching on the standing lamps ensures thecorresponding side of the vehicle is illumina-ted.

The cornering lamp may remain lit for a shorttime, but is automatically switched off after nomore than three minutes.
Cornering light function with traffic circlefunction:
The cornering light function is activated onboth sides before entering a traffic circlethrough an evaluation of the current GPS posi-tion of the vehicle. It remains active until afterthe vehicle has left the traffic circle. In thisway, pedestrians crossing the road, for exam-ple, are illuminated by your vehicle in goodtime.
Active light function
The active light function is a system thatmoves the headlamps according to the steer-ing movements of the front wheels. In thisway, relevant areas remain illuminated whiledriving. This allows you to recognize pedes-trians, cyclists and animals sooner.
Active:when the lights are switched on.
Vehicles with Lane Keeping Assist: the activelight function evaluates the course of the lanein which you are driving and pre-emptivelycontrols the active light function.
Adaptive Highbeam Assist
General notes
You can use this function to set the headlampsto change between low beam and high beamautomatically. The system recognizes vehicleswith their lights on, either approaching fromthe opposite direction or traveling in front ofyour vehicle, and consequently switches theheadlamps from high beam to low beam.
The system automatically adapts the low-beamheadlamp range depending on the distance tothe other vehicle. Once the system no longerdetects any other vehicles, it reactivates thehigh-beam headlamps.
The system's optical sensor is located behindthe windshield near the overhead controlpanel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recog-
nize 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
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be
deactivated or will be activated regardless.
There is a risk of an accident.
Always carefully observe the traffic condi-
tions and switch off the high-beam head-
lamps in good time.
Adaptive Highbeam Assist cannot take intoaccount road, weather or traffic conditions.Adaptive Highbeam Assist is only an aid. Youare responsible for adjusting the vehicle'slighting to the prevailing light, visibility andtraffic conditions.
In particular, the detection of obstacles can berestricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain orsnow
Rdirt on the sensors or the sensors areobscured

The high-beam headlamps are switched onautomatically. TheWindicator lamp inthe instrument cluster also lights up.
If you are driving at speeds below approx-imately 16 mph (25 km/h) or other roadusers have been detected or the roads areadequately lit:
The high-beam headlamps are switched offautomatically. TheWindicator lamp inthe instrument cluster goes out. The

bulbs of the same type and the specified volt-age.
Marks on the glass tube reduce the service lifeof the bulbs. Do not touch the glass tube withyour bare hands. If necessary, clean the glasstube when cold with alcohol or spirit and rub itoff with a lint-free cloth.
Protect bulbs from moisture during operation.Do not allow bulbs to come into contact withliquids.
Only replace the lamps listed (Ypage 102).Have the bulbs that you cannot replace your-self replaced at a qualified specialist work-shop.
If you require assistance replacing lamps, con-sult a qualified specialist workshop.
If the new lamp still does not light up, consulta qualified specialist workshop.
Bulbs and lamps are an important aspect ofvehicle safety. You must therefore make surethat these function correctly at all times. Havethe headlamp setting checked regularly.
