In such situations, turn the light switch to
X .
Even if the light sensor does not detect that it is
dark, the parking lamps and low-beam head-
lamps switch on when the ignition is switched on
and the light switch is set to the X position.
This is ap articularly useful function in the event
of rain and fog. X
To switch on the low-beam headlamps:

lamp sf rom high bea mtol ow beam.
The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
detects any other vehicles, it reactivates the
high-beam headlamps.
The system' so ptical sensor is located behind
the windshiel dn ear the overhea dc ontrol panel.
Important safety notes
G WARNING
Adaptive Highbeam Assist does not recognize
road users: R
who have no lights, e.g. pedestrians R
who have poor lighting, e.g. cyclists R
whos el ighting is blocked ,e .g. by ab arrier
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 headlamp sw il ln ot be deac-
tivated or wil lbea ctivated regardless. There is
ar isk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamp si n
good time.
Adaptive Highbeam Assist cannot take into
account road ,w eather or traffic conditions.
Adaptive Highbeam Assist is only an aid .Y ou 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
restricted if there is: R
poor visibility, e.g. due to fog, heavy rain or
snow R
dirt on the sensors or the sensors are
obscured Switching Adaptive Highbeam Assist

Windshield wipers
Switching the windshield wipers
on/off
! Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratc ht he glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, alway su se
washer fluid when operating the windshield
wipers.
! If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
! Intermittent wiping with rain sensor: due to
optical 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 wiper
blades or scratc ht he windshield.
For this reason, you should alway ss witch off
the windshield wipers in dry weather. Combination switch

Adaptive damping system
General notes
i Mercedes-AMG SLC 43: the adaptive
damping system is called AMG RIDE CON-
TROL sports suspension.
As uspension with the adaptive damping system
provides improved driving comfort and contin-
uously controls the calibration of the dampers.
The damping characteristic sa dapt to the cur-
rent operating and driving situation.
The damping is tuned individually to each wheel
and depends on: R
your driving style, e.g. sporty R
the road surface conditions R
the selected drive program ( Y
page 121).
Selecting the Comfort or Economy drive
programs In the Comfort and Economy drive programs,
the driving characteristic sofy our vehicle are
more comfortable. Select one of these drive
programs if you favor am ore comfortable driv-
ing style. Also select these drive programs when
driving fast on straight roads, e.g. on straight
stretches of highway.
In urban traffic and stop-start traffic, drive pro-
gram C is recommended. X
Press DYNAMIC SELECT button C repeat-
edly until the Comfort or Economy drive pro-
gram is selected.
Selecting Sport mode The firmer setting of the suspension tunin gi n
the Sport drive program ensures even better
contact with the road. Select this drive program
when employing as porty driving style, e.g. on
winding country roads. X
Press DYNAMIC SELECT button C as many
times as necessary until the Sport drive pro-
gram is selected.
Selecting Sport Plus mode The firmer suspension settings in the Sport
Plus drive program ensure even better contact
with the road. Select this mode when employing
as porty driving style, e.g. on winding country
roads or, ideally ,w hen driving on closed race
circuits. X

Parking Guidance
Important safety notes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. As uitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You can also still use Active Parking
Assist PARKTRONIC ( Y
page 149).
Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that there are no per-
sons, animals or object sint he maneuvering
area when you are maneuvering or parking.
G WARNING
If object sa re located above or below the
detection range, Active Parking Assist may
steer too early. This could cause ac ollision. There is ar isk of an accident.
Do not use Active Parking Assist in these
types of situation.
! If they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
If Active Parking Assist PARKTRONIC is deacti-
vated, Parking Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Use Parking Guidance for parking spaces: R
paralle ltot he direction of travel R
on straight roads, not bends R
that are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs152

Blind Spot Assist monitors the are aupto10f t
(3.0 m) behind your vehicle and directly nex tt o
your vehicle, as shown in the diagram. For this
purpose, Blind Spot Assist uses radar sensor si n
the rear bumper.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nex ttoy our vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if ther ea re vehicles driving at the inner
edge of their lanes.
Due to the natur eoft he system:R
warning sm ay be issued in error when driving
close to crash barriers or similar solid lane
borders. R
warning sm ay be interrupted when driving
alongside long vehicles, e.g. trucks, for ap ro-
longed time.
