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.
XTo switch on the standing lamps:theSmartKey is not in the ignition lock or it is inposition

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 area behind the vehicle is displayed as amirror image, as in the rear view mirror.
iThe text shown in the multimedia systemdisplay depends on the language setting.The following are examples of rear viewcamera displays in the multimedia system.
Important safety notes
The rear view camera is only an aid. It is not areplacement for your attention to your immedi-ate surroundings. You are always responsiblefor safe maneuvering and parking. Make surethat there are no persons, animals or objectsin the maneuvering area when you are maneu-vering or parking.
Under the following circumstances, the rearview camera will not function, or will functionin a limited manner:
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LEDlighting (the display may flicker)
Rif there is a sudden change in temperature,e.g. when driving into a heated garage inwinter
Rif the camera lens is dirty or obstructed.Observe the notes on cleaning(Ypage 250)
Rif the rear of your vehicle is damaged. In thiscase, have the camera position and settingchecked at a qualified specialist workshop.
The field of vision and other functions of therear view camera may be restricted due toadditional accessories on the rear of the vehi-cle (e.g. license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,leaving the standard height can result in inac-curacies in the guide lines, depending on tech-nical conditions.
iThe contrast of the display may be affec-ted by the sudden presence of sunlight orother light sources, e.g. when exiting agarage. Pay particular attention in this situa-tion.
iIf usability is severely restricted, e.g. dueto pixel errors, have the display repaired orreplaced.
iThe rear view camera is protected fromraindrops and dust by means of a flap. Whenthe rear view camera is activated, this flapopens.
The flap closes again when:
Ryou have finished the maneuvering proc-ess
Ryou switch off the engine
Ryou open the trunk
