The blueWindicator lamp in the instru-ment cluster lights up when the high-beamheadlamps are switched on.
XTo switch off the high-beam headlamps:move the combination switch back to itsnormal position.The blueWindicator lamp in the instru-ment cluster goes out.
Hazard warning lamps
XTo switch on the hazard warning lamps:press buttonC.All turn signals flash. If you now switch on aturn signal using the combination switch,only the turn signal lamp on the correspond-ing side of the vehicle will flash.
XTo switch off the hazard warning lamps:press buttonC.
The hazard warning lamps automaticallyswitch on if:
Ran air bag is deployed or
Rthe vehicle decelerates rapidly from a speedof above 45 mph (70 km/h) and comes to astandstill
The hazard warning lamps switch off automati-cally if the vehicle reaches a speed of above6 mph (10 km/h) again after a full brake appli-cation.
iThe hazard warning lamps still operate ifthe ignition is switched off.
Cornering light function
The cornering light function improves the illu-mination of the road over a wide angle in thedirection you are turning, enabling better visi-bility in tight bends, for example. The corner-
ing light function can only be activated whenthe low-beam headlamps are switched on.
Active:
Rif you are driving at speeds below 25 mph(40 km/h) and switch on the turn signal orturn the steering wheel
Rif you are driving at speeds between 25 mph(40 km/h) and 45 mph (70 km/h) and turnthe steering wheel
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 longer

Windshield wipers
Switching the windshield wipers
on/off
!Do not operate the windshield wiperswhen the windshield is dry, as this could
damage 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.

!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.

XTurn the SmartKey to positionGorHinthe ignition lock.
XSet the windshield wiper to position

GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake
can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident.
Release the parking brake fully before driv-
ing off.
!Do not warm up the engine while station-ary. Pull away immediately. Avoid highengine speeds and full throttle until theengine has reached its operating tempera-ture.
In vehicles with automatic transmission,engage positions P and R only when thevehicle is stationary.
Where possible, avoid spinning the drivewheels when pulling away on slippery roads.You could otherwise damage the drive train.
!Mercedes-AMG vehicles:at low engineoil temperatures below 68 ‡ (+20 †), themaximum engine speed is restricted inorder to protect the engine. To protect theengine and maintain smooth engine opera-tion, avoid driving at full throttle when theengine is cold.

KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped witha SmartKey featuring an integrated KEYLESS-GO start function and a detachable Start/Stopbutton.
The Start/Stop button must be inserted in theignition lock and the SmartKey must be in thevehicle.
When you insert the Start/Stop button intothe ignition lock, the system needs approx-imately two seconds recognition time. You canthen use the Start/Stop button.
Pressing the Start/Stop button several timesin succession corresponds to the different keypositions in the ignition lock. This is only thecase if you are not depressing the brake pedal.
If you depress the brake pedal and press theStart/Stop button, the engine starts immedi-ately.
A check which periodically establishes a radioconnection between the vehicle and theSmartKey determines whether a valid Smart-

To start the vehicle without actively using theSmartKey:
Rthe Start/Stop button must be inserted inthe ignition lock.
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with theSmartKey or KEYLESS-GO (Ypage 74).
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phoneor another SmartKey.
Rwith metallic objects, e.g. coins or metalfoil.
Rinside metallic objects, e.g. a metal case.
This can impair the functionality of the KEY-LESS-GO key.
If you lock the vehicle with the SmartKey'sremote control or with KEYLESS-GO, after ashort time:
Ryou will not be able to switch on the ignitionwith the Start/Stop button.
Ryou will not be able to start the engine withthe Start/Stop button until the vehicle isunlocked again.
