Sliding sunroof reversing feature
The sliding sunroof is equipped with an auto-
matic reversing function. If an solid object
blocks or restricts the sliding sunroof during the
closing process, the sliding sunroof opens again automatically. The automatic reversing function
is only an aid and is not a substitute for your
attention when closing the sliding roof. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 4 mm of the closing movement
R during resetting
R when closing the sliding sunroof again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing make sure that no body parts
are in the closing area.
If someone is trapped:
R release the switch immediately or
R press the switch in any direction during the
automatic closing process

General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with lights switched on
even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and voluntary recommendations. Driving abroad
Vehicles with halogen headlamps It is not necessary to switch your headlamps to
symmetrical dipped beam when driving in coun- tries where vehicles are driven on the opposite
side of the road to the country in which the vehi-
cle is registered. Legal requirements are fulfilled
without switching the headlamps to symmetri-
cal dipped beam.
Vehicles with Intelligent Light System It is necessary to switch your headlamps to sym-
metrical dipped beam before crossing the bor-
der into countries where vehicles are driven on
the opposite side of the road. This prevents
oncoming traffic from being dazzled.
You can switch the headlamps to symmetrical or
asymmetrical dipped beam using the "dipped-
beam headlamps for driving on the right/left"
function via the on-board computer
(Y page 244). This must be switched back to
asymmetrical dipped beam upon your return.
Symmetrical lights do not illuminate as large an
area of the edge of the carriageway. In this case,
"highway mode" and "extended-range fog
lamps" are not available. Setting the exterior lighting
Setting options Exterior lighting can be set using the:

Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to switch automatically between dipped beam
and main beam. The system recognises vehicles
with their lights on, either approaching from the opposite direction or travelling in front of your
vehicle, and consequently switches the head-
lamps from main beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system no
longer detects any other vehicles, it switches on
the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognise other road users
that have lights, or may recognise them too
late. In this, or in similar situations, the auto-
matic main-beam headlamps will not be deac-
tivated or will be activated despite the pres-
ence of other road users. There is a risk of an accident.
Always carefully observe the traffic conditionsand switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions. In particular, the detection of obstacles can be
impaired in the case of:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or obscured sensors

lamps.
If you are driving at speeds above approx-
imately 25 km/h:
The headlamp range is set automatically
depending on the distance between the vehi- cle and other road users.
If you are driving at speeds above approx-
imately 30 km/h and no other road users are
detected:
The main-beam headlamps are switched on
automatically. The Kindicator lamp on the
instrument cluster also lights up.
If you are driving at speeds below 25 km/h or

General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illumination is a form of illu-
mination whereby the main beam is directed Exterior lighting
119Lights and windscreen wipers Z

past other road users. Other road users are kept
out of the main beam. This prevents glare. If
there is a vehicle in front, for example, the main- beam headlamps illuminate the areas to its right
and left, and the vehicle in front is illuminated by the dipped-beam headlamps.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system no
longer detects any other vehicles, it switches on
the main-beam headlamps again.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf- fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflectionsis thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.

! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen wipers in dry weather conditions, always
operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen. Windscreen wipers

Running-in notes
Important safety notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective-
ness is not reached until the end of this teach-in process.
Brake pads/linings and discs that either are new or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. The first 1500 km
The more you treat the engine with sufficient
care at the start, the more satisfied you will be
with the engine performance later on.
R You should therefore drive at varying road
speeds and engine speeds for the first
1500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R When shifting gears manually, shift up in good
time, before the rev counter needle reaches
Ô of the way to the red area of the rev counter
display.
R Do not shift down a gear manually in order to
brake.
R Try to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1500 km, you can increase the engine
speed gradually and accelerate the vehicle to
full speed.
You should also observe these notes on running- in if the engine or parts of the drive train on your
vehicle have been replaced.
Always observe the maximum permissible
speed. Driving
