Adaptive Damping System
General notes
i Mercedes-Benz SLC 43 AMG: the adap-
tive adjustable damping is called AMG sports
suspension.
As uspension with the Adaptive Damping Sys-
tem provides improved driving comfort and con-
tinuously controls the calibration of the damp-
ers. The damping characteristic sa dapt to the
curren to perating 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. 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

PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area around
your vehicle using six sensor sint he front
bumper and four sensor sint he rear bumper.
PARKTRONIC indicates visually and audibly the
distanc eb etween your vehicle and an object.
PARKTRONIC is only an aid. It is not ar eplace-
ment for your attention to your immediate sur-
roundings .Y ou are alway sr esponsible for safe
maneuvering, parking and exitin gap arking
space. When maneuvering, parking or pulling
out of ap arking space, make sure that there are
no persons ,a nimals or object sint he area in
which you are maneuvering.Driving systems 149
Driving and parking Z

! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on at ruck
or ap neumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automaticall yw hen
you: R
switch on the ignition R
shift the transmission to position D , R or NR
release the electric parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors
General notes PARKTRONIC does not take objects into con-
sideration that are: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, e.g. overhanging
loads, truck overhangs or loading ramps.
C
Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them ( Y
