Problems with the side windows
GWARNING
If you close a side window again immediately after it has been blocked or reset, the side window
closes with increased or maximum force. The reversing feature is then not active. Parts of the
body could be trapped in the closing area in the process. This poses an increased risk of injury or
even fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process, release
the switch or push the switch again to reopen the side window.
ProblemPossible causes/consequences andPPSolutions
A side window cannot beclosed because it isblocked by objects, e.g.leaves in the windowguide.
XRemove the objects.
XClose the side window.
A side window cannot beclosed and you cannotsee the cause.
If a side window is obstructed during closing and reopens againslightly:
XImmediately after the window blocks, pull the corresponding switchagain until the side window has closed.The side window is closed with increased force.

When the engine is running and the vehicle isstationary: if you move the selector lever from adriving position to], the daytime driving lightsand low-beam headlamps go out after threeminutes.
When the engine is running, the vehicle is sta-tionary and in bright ambient light: if you turn thelight switch to the`position, the daytimerunning lamps and parking lamps switch on.
If the engine is running and you turn the lightswitch to theXposition, 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 it isdark, the parking lamps and low-beam head-lamps switch on when the ignition is switched onand the light switch is set to theXposition.This is a particularly useful function in the eventof 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 to theXposition.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 of thickfog. You must observe the legal requirementsfor the country in which you are currently drivingwhen operating the rear fog lamp.
XTo switch on the rear fog lamp:turn theSmartKey in the ignition lock to positionHorstart the engine.
XTurn the light switch to theXorXposition.

Parking lamps
!If the battery charge is very low, the parkinglamps or standing lamps are automaticallyswitched off to enable the next engine start.Always park your vehicle safely and in a well litarea, in accordance with the relevant legalstipulations. Avoid using the`parkinglamps over a period of several hours. If pos-sible, switch on the right-handdor left-handcstanding lamps.

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 control panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
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 deac-
tivated or will be activated regardless. There is
a risk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take intoaccount road, weather or traffic conditions.Adaptive Highbeam Assist is only an aid. You areresponsible for adjusting the vehicle's lightingto the prevailing light, visibility and traffic con-ditions.
In particular, the detection of obstacles can beimpaired if:
Rthere is poor visibility, e.g. due to fog, heavyrain or snow
Rthere is dirt on the sensors or anything elsecovering the sensors

!Do not operate the windshield wipers whenthe windshield is dry, as this could damagethe wiper blades. Moreover, dust that has col-lected on the windshield can scratch the glassif wiping takes place when the windshield isdry.
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 on thewindshield after the vehicle has been washedin an automatic car wash, wax or other resi-dues may be the reason for this. Clean thewindshield using washer fluid after washingthe vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due tooptical influences and the windshield becom-ing dirty in dry weather conditions, the wind-shield wipers may be activated inadvertently.This could then damage the windshield wiperblades or scratch the windshield.

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and drivingsafety systems adjusts automatically while acertain distance is being driven after the vehiclehas been delivered or after repairs. Full systemeffectiveness is not reached until the end of thisteach-in procedure.
New and replaced brake pads and discs onlyreach their optimum braking effect after severalhundred kilometers of driving. Compensate forthis by applying greater force to the brake pedal.
The first 1,000 miles (1,500 km)
The more you look after the engine when it isnew, the more satisfied you will be with its per-formance in the future.
RYou should therefore drive at varying vehicleand engine speeds for the first 1,000 miles(1,500 km).
RAvoid heavy loads, e.g. driving at full throttle,during this period.
RWhen changing gears manually, change up ingood time. Change gear before the tachome-ter needle is

Active Distance Assist DISTRONIC
General notes
Active Distance Assist DISTRONIC regulates thespeed and automatically helps you maintain thedistance from the vehicle detected in front.Vehicles are detected with the aid of the radarsensor system. Active Distance AssistDISTRONIC brakes automatically so that the setspeed is not exceeded.
Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden. By doing so, youwill make use of the braking effect of the engine.This relieves the load on the brake system andprevents the brakes from overheating and wear-ing too quickly.
If Active Distance Assist DISTRONIC detectsthat there is a risk of a collision with the vehiclein front, you will be warned visually and audibly.Active Distance Assist DISTRONIC cannot pre-vent a collision without your intervention. Anintermittent warning tone will then sound andthe distance warning lamp will light up in theinstrument cluster. Brake immediately in orderto increase the distance to the vehicle in front ortake evasive action provided it is safe to do so.
Active Distance Assist DISTRONIC operates inthe speed range between 0 mph(0 km/h) and120 mph (200 km/h).
Do not use Active Distance Assist DISTRONICwhile driving on roads with steep gradients.
As Active Distance Assist DISTRONIC transmitsradar waves, it can resemble the radar detectorsof the responsible authorities. You can refer tothe relevant chapter in the Operator's Manual ifquestions are asked about this.

Important safety notes
GWARNING
Active Distance Assist DISTRONIC does not
react to:
Rpeople or animals
Rstationary objects in the road, e.g. stopped
or parked vehicles
Roncoming vehicles and crossing traffic
As a result, Active Distance Assist DISTRONIC
may neither give warnings nor intervene in
such situations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
GWARNING
Active Distance Assist DISTRONIC cannot
always clearly identify other road users and
complex traffic situations.
In such cases, Active Distance Assist
DISTRONIC can:
Rgive an unnecessary warning and then
brake the vehicle
Rneither give a warning nor intervene
Raccelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Active Distance Assist
DISTRONIC warns you.
