Automatic anti-glare mirrors
GWARNING
Electrolyte may escape if the glass in an
automatic anti-glare mirror breaks. The elec-
trolyte is harmful and causes irritation. It
must not come into contact with your skin,
eyes, respiratory organs or clothing or be
swallowed. There is a risk of injury.
If you come into contact with the electro-
lyte, observe the following:
RRinse off the electrolyte from your skin
immediately with water.
RImmediately rinse the electrolyte out of
your eyes thoroughly with clean water.
RIf the electrolyte is swallowed, immedi-
ately rinse your mouth out thoroughly. Do
not induce vomiting.
RIf electrolyte comes into contact with your
skin or hair or is swallowed, seek medical
attention immediately.
RImmediately change out of clothing which
has come into contact with electrolyte.
RIf an allergic reaction occurs, seek medi-
cal attention immediately.
The rear-view mirror and the exterior mirror onthe driver's side automatically go into anti-glare mode if the following conditions are metsimultaneously:

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.
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 several
hours. If possible, switch on the right-handdor left-handcstanding lamps.

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

XTo switch off:set the switch to the3position.
The interior lighting automatically switches onif you:
Runlock the vehicle
Ropen a door
Rremove the SmartKey from the ignition lock
The interior lighting is switched on for a settime when the SmartKey is removed from theignition lock. You can activate this delayedswitch-off using the on-board computer(Ypage 201).
Replacing bulbs
The front and rear lamps of your vehicle areequipped with LED bulbs. Do not replace thebulbs yourself. Contact a qualified specialistworkshop which has the necessary specialistknowledge and tools to carry out the workrequired.
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.
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.

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 vehi-cle has been delivered or after repairs. Fullsystem effectiveness is not reached until theend of this teach-in procedure.
New and replaced brake pads and discs onlyreach their optimum braking effect after sev-eral hundred kilometers of driving. Compen-sate for this by applying greater force to thebrake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it isnew, the more satisfied you will be with itsperformance 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 throt-tle, during this period.
RChange gear in good time, before the tach-ometer needle is

Active Distance Assist DISTRONIC
General notes
Active Distance Assist DISTRONIC regulatesthe speed and automatically helps you main-tain the distance from the vehicle detected infront. Vehicles are detected with the aid of theradar sensor system. Active Distance AssistDISTRONIC brakes automatically to avoidexceeding the set speed or to maintain thedesignated distance from the vehicle in front.
You must select a lower gear in good time onlong and steep downhill gradients, especially ifthe vehicle is laden. By doing so, you will makeuse of the braking effect of the engine. Thisrelieves the load on the brake system and pre-vents the brakes from overheating and wear-ing too quickly.
If Active Distance Assist DISTRONIC detectsthat there is a risk of a collision with the vehi-cle in front, you will be warned visually andaudibly. Active Distance Assist DISTRONICcannot prevent a collision without your inter-vention. An intermittent warning tone will thensound and the distance warning lamp will lightup in the instrument cluster. Brake immedi-ately in order to increase the distance fromthe vehicle in front, or take evasive action, pro-vided it is safe to do so.
For Active Distance Assist DISTRONIC toassist you when driving, the radar sensor sys-tem must be operational.
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 trans-mits radar waves, it can resemble the radardetectors of the responsible authorities. Youcan refer to the relevant chapter in the Opera-tor's Manual if questions are asked about this.
