speed foraprolonged period. You can store any
road speed above 20 mph (30 km/h).
Important safety notes
If you fail to adapty our driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front,f or vehicle speed, for braking in
good time and for staying in lane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain aconstant speed e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is achange of drivers, advise the new
driver of the speed stored.

?Deactivating cruise control
When you activate cruise control, the stored
speed is shown in the multifunction displayf or
five seconds. The speed is then permanently
displayed in the status indicator together with
the ¯ symbol.
On vehicles with asegment ring in the speed-
ometer, the segments from the currently saved speed to the end of the segment ring light up.

XBriefly press the cruise control lever up :or
down ?.
XRemove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
You can store the current speed if you are driv-
ing faster than 20 mph (30 km/h).
iCruise control may be unable to maintain
the stored speed on uphillg radients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by auto-
matically applying the brakes.
Storing or callingupa speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is arisk of an acci-
dent.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you =.
XRemove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously stored
speed.
Setting aspeed
GWARNING
Keep in mind that it may take abrief moment
until the vehicle has made the necessary
adjustments.
Increase or decrease the set vehicle speed to

and unexpected acceleration or deceleration
of the vehicle could cause an accident and/or serious injury to you and others.
XTo adjust th eset speed in 1mphincre-
ment s(1k m/hincrements): briefly press
the cruis econtrol lever up :to the pressure
point for ahigher speed, or down ?for a
lower speed.
Every tim ethe cruis econtrol lever is pressed
up or down, the last speed stored is increased
or reduced.
XTo adjust th eset speed in 5mphincre-
ment s(10 km/h increments): briefly press
the cruis econtrol lever up :past the pres-
sure point for ahigher speed, or down ?for
al ower speed.
Every tim ethe cruis econtrol lever is pressed
up or down, the last speed stored is increased or reduced.
iThe speed indicated in the speedometer
may differs lightly fromt he speed stored.
iCruise control is not deactivate difyou

you accelerateb riefly to overtake, cruis econ-
trol adjust sthe vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control
There are several ways to deactivate cruis econ-
trol:
XBriefly press the cruis econtrol lever for-
wards :.

Distance Pilot DISTRONIC
General notes
Distanc eAssist DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance fromt he vehicle detected in front .Vehi-
cles are detected with the aid of the radar sen-
sor system. Distanc eAssist DISTRONIC brakes
automatically to avoid exceeding the set speed
or to maintain the designated distanc efromt he
vehicle in front.
Change int oalower gear in good tim eonlong
and steep downhill gradients. This is especially
importan tifthe vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brakes ystem and
prevent sthe brakes fromo verheatingand wear-
ing too quickly.
If Distanc eAssist DISTRONIC detect sthat there
is ar isk of acollision with the vehicle in front,
you will be warne dvisually and audibly. Distance
Assist DISTRONIC cannot prevent acollision
without your intervention. An intermitten twarn-
ing ton ewill the nsound and the distanc ewarn-
ing lamp will light up in the instrumentc luster.
Brak eimmediately in order to increase the dis-
tance fromt he vehicle in front ,ortakee vasive
action, provided it is safe to do so.
For Distanc eAssist DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Distanc eAssist DISTRONIC operates in the
speed rang ebetwee n0mph (0 km/h) and
120 mph (200 km/h).

Adaptive damping system
General notes
iMercedes-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 sadapt to the cur-
rent operating and driving situation.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface conditions
Rthe selected drive program (Ypage 121).
Selecting the Comfort or Economy drive
programs
In the Comfort andEconomy drive programs,
the driving characteristic sofyour vehicle are
more comfortable. Select one of these drive
programs if you favor amore 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 Cis recommended.
XPress DYNAMIC SELECT button :repeat-
edly until the ComfortorEconomy drive pro-
gram is selected.
Selecting Sport mode
The firmer setting of the suspension tunin gin
the Sport drive program ensures even better
contact with the road. Select this drive program
when employing asporty driving style, e.g. on
winding country roads.
XPress DYNAMIC SELECT button :as many
times as necessary until the Sportdrive 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.
XPress DYNAMIC SELECT button :repeat-
