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.

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. Asuitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You can also still use Active Parking
Assist PARKTRONIC (
Ypage 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 sinthe maneuvering
area when you are maneuvering or parking.
GWARNING
If object sare located above or below the
detection range, Active Parking Assist may
steer too early. This could cause acollision.
There is arisk 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.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Use Parking Guidance for parking spaces:
Rparalleltot he direction of travel
Ron straight roads, not bends
Rthat are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 159) and Lane Keeping
Assist (Ypage 161).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. Awarning display in the exterior mirrors
draws your attention to vehicles detected in the
monitored area. If you then switch on the cor-
respondingt urn signal to change lane, you will
also receive an optical and audible warning.
Blind Spot Assist supports you from aspeed of
approximately 20 mph (30 km/h).
For Blind Spot Assist to assist you, the radar
sensor system must be operational.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with alarge speed
differential and overtake your vehicle
As aresult, Blind Spot Assist may not give
warnings in such situations .There is arisk of
an accident.
Always observe the traffic conditions care-
fully, and maintain asafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitut efor attentive driving. Always ensure that there is
sufficientd
istancetothe side for other road
users and obstacles.
iUSA only:
This device has been approved by the FCC as
a" Vehicular Radar System". The radar sensor
is intended for use in an automotiv eradar
system only. Removing, tamperin gwith, or
altering the device will void any warranties,
and is not permitted by the FCC. Do not tam-
per with, alter, or use in any non-approved
way.
An yu nauthorized modification to this device
could void the user’s authority to operate the
equipment.
Radar sensors
The radar sensor sfor Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the bumpers are free from dirt, ice or slush. The
sensor smust not be covered, for example by
cycle racks or overhangin gloads. Following a
severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at aqualified specialist workshop.
Blind Spot Assist may no longer work properly.
Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensor soranything else
coveringt he sensors
Rthere is poor visibility, e.g. due to fog, heavy
rain, snow or spray
Rthere are narrow vehicles, e.g. motorcycles or
bicycles
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.

Blind Spot Assist monitors the areaupto10ft
(3.0 m)behind your vehicle and directly nex tto
your vehicle, as shown in the diagram. For this
purpose, Blind Spot Assist uses radar sensor sin
the rear bumper.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nex ttoyour 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 eare vehicles driving at the inner
edge of their lanes.
Due to the natur eofthe system:
Rwarning smay be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarning smay be interrupted when driving
alongside long vehicles, e.g. trucks, for apro-
longed time.
