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

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.
Vehicles with LED headlamps

!Do not operate the windshield wiperswhen the windshield is dry, as this coulddamage the wiper blades. Moreover, dustthat has collected on the windshield canscratch the glass if wiping takes place whenthe windshield is dry.
If it is necessary to switch on the windshieldwipers in dry weather conditions, always usewasher fluid when operating the windshieldwipers.
!If the windshield wipers leave smears onthe windshield after the vehicle has beenwashed in an automatic car wash, wax orother residues may be the reason for this.Clean the windshield using washer fluidafter washing the vehicle in an automaticcar wash.
!Intermittent wiping with rain sensor: dueto optical influences and the windshieldbecoming dirty in dry weather conditions,the windshield wipers may be activatedinadvertently. This could then damage thewindshield wiper blades or scratch the wind-shield.
For this reason, you should always switchoff the windshield wipers in dry weather.

Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you
could be trapped by the wiper arm. There is
a risk of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!To avoid damaging the wiper blades, makesure that you touch only the wiper arm ofthe wiper.
!Never open the hood if a windshield wiperarm has been folded away from the wind-shield.
Never fold a windshield wiper arm without awiper blade back onto the windshield.
Hold the windshield wiper arm firmly whenyou change the wiper blade. If you releasethe windshield wiper arm without a wiperblade and it falls onto the windshield, thewindshield may be damaged by the force ofthe impact.
Mercedes-Benz recommends that you havethe wiper blades changed at a qualified spe-cialist workshop.
!Always position the windshield wiper armsvertically before folding them away from thewindshield. By doing so, you will avoid dam-age to the hood.

Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwisefog up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-tion function
Rswitch on the defrost windshield functionbriefly, if required
Climate control regulates the temperature andthe humidity in the vehicle interior and filtersundesirable substances out of the air.
Climate control can only be operated when theengine is running. Optimum operation is only
achieved with the side windows and roofclosed.
iWhen the weather is warm, ventilate thevehicle for a brief period. This will speed upthe cooling process and the desired vehicleinterior temperature will be reached morequickly.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollu-tants and odors. A clogged filter reduces theamount of air supplied to the vehicle inte-rior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the Maintenance Book-let. As it depends on environmental condi-tions, e.g. heavy air pollution, the intervalmay be shorter than stated in the Mainte-nance Booklet.
