You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steerin gand braking manoeuvres .Donot use
cruis econtrol or DISTRONIC PLUS.
If the vehicle threaten stoskid or cannot be
stopped when movin gatlow speed:
X Vehicles with manual transmission: shift
to neutral.
X Vehicles with automatic transmission:
shift the transmission to position
N.
X Try to brin gthe vehicle under control by using
correctiv esteering.
The outsid etemperature indicator is not
designed to serv easanice-warnin gdevic eand
is therefore unsuitable for that purpose.
Changes in the outsid etemperature are dis-
played afte rashortdelay.
Indicated temperatures just above the freezing
point do not guarantee that the road surfac eis
free of ice. The road may still be icy, especially in wooded areas or on bridges .The vehicle could
skid if you fail to adapt your drivin gstyle. Always
adapt your drivin gstyle and drive at aspeed to
suit the prevailin gweather conditions.
You should pay special attention to road condi-
tion swhen temperatures are around freezing
point.

Genera lnotes Cruise control maintains
aconstan troad speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Change int oalower
gear in good tim eonlong and steep downhill
gradients. Take particular not eofthis when driv-
ing aladen vehicle and when towin gatrailer. By
doing so, you will make use of the braking effect
of the engine. This relieve sthe load on the brake
syste mand prevent sthe brakes from overheat-
ing and wearing too quickly.
Use cruis econtrol only if road and traffic con-
dition sare appropriate for maintainin gasteady
speed for aprolonged period. You can store any
road speed above 30 km/h.
Important safet ynotes If you fail to adapt your drivin
gstyle, cruis econ-
trol can neither reduce the risk of an accident
nor override the laws of physics .Cruise control
cannot tak eintoa ccount road, weather or traffic
conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time,
and for stayin ginlane.
Do not use cruis econtrol:
R in road and traffic condition swhich do not
allow you to maintain aconstan tspeed, e.g. in
heavy traffic or on windin groads
R on smoot horslippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could the nskid
R when 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.

X Keep the cruise control lever pressed until the
desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
X To adjust the set speed in
1km/h incre-
ments: briefly press the cruise control lever
up : or down ?to the pressure point.
The last stored speed increases or decreases
in 1k m/h increments.
X To adjust the set speed in 10 km/h incre-
ments: briefly press the cruise control lever
up : or down ?beyond the pressure point.
The last stored speed increases or decreases in 10 km/h increments.
i Cruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate to overtake, cruise control adjusts the
vehicle's speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control There are several ways to deactivate cruise con-
trol:
X Briefly press the cruise control lever forwards

If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise con‐
Cruise con‐
trol off trol off message in the multifunction display
for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
General notes SPEEDTRONIC brakes automatically so that you
do not exceed the set speed. Change into a
lower gear in good time on long and steep down-
hill gradients. Take particular note of this when
driving aladen vehicle. By doing so, you will
make use of the braking effect of the engine.
This relieves the load on the brake system and
preventst he brakes from overheating and wear-
ing too quickly.
Important safety notes If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an acci-
dent nor override the laws of physics. SPEED-
TRONIC cannot take into account road, weather or traffic conditions. SPEEDTRONIC 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.
If there is achange of drivers, advise the new
driver of the speed stored.
You can set avariable or permanent limit speed:
R variable for speed limits, e.g. in built-up areas
R permanent for long-term speed restrictions,
e.g. when driving with winter tyres fitted
(Y page 184)
i The speed indicated in the speedometer
may differ slightly from the limit speed stored. 182
Driving systemsDriving and parking

Switching SPEEDTRONIC to passive
If you depress the accelerator pedal beyond the
pressure point (kickdown), SPEEDTRONIC is
switched to passive mode. The SPEEDTRONIC SPEEDTRONIC
suspended
suspended message appears in the multifunc-
tion display.
You can then exceed the stored speed. SPEED-
TRONIC is activated again if you:
R drive slower than the stored speed without
kickdown
R set anew speed or
R call up the last speed stored again
The SPEEDTRONIC suspended SPEEDTRONIC suspended message in the
multifunction display disappears.
Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable SPEED-
TRONIC by braking.
There are several ways to deactivate variable
SPEEDTRONIC:
X Briefly press the cruise control lever forwards
B.
or X Briefly press the cruise control lever in the
direction of arrow A.
LIM indicator lamp ;in the cruise control
lever goes out. Variable SPEEDTRONIC is
deactivated.
Cruise control or DISTRONIC PLUS is selec-
ted.
i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC
You can use the on-board computer to limit the
speed permanently to avalue between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed (Y page 248).
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active, even
if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed, even if you depress the accelerator pedal beyond the
pressure point (kickdown). DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front.V ehicles are detected
with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into alower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving aladen vehicle. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and preventst he brakes from overheat-
ing and wearing too quickly.
If DISTRONIC PLUS detectst hat there isarisk of
ac ollision, you will be warned visuallya nd
acoustically. Without your intervention,
DISTRONIC PLUS cannot prevent acollision. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the
instrumen tcluster. Brake immediately to
increase the distance to the vehicle driving in
front,ort ake evasive action, provided it is safe
to do so.
DISTRONIC PLUS operates in the range
between 0km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncominga nd crossing traffic
As aresult, DISTRONIC PLUS may neither give
warnings nor interveneins uch situations.
There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions. 184
Driving systemsDriving and parking

Only release the ball coupling if the pivoting
range is unobstructed. Alwaysm ake sure that
the ball coupling engages when folding in.
When reversing the vehicle towards the trailer,
make sure there is nobody between the trailer
and the vehicle.
Couple and uncouple the trailer carefully.Ify ou
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing atrailer, your vehicle's handling
characteristics will be different in comparison to when driving without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has alarger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain asafe distance. Drive carefully.
When towing atrailer, always adjust your speed
to the current road and weather conditions. Do
not exceed the maximum permissibles peed for
your vehicle/trailer combination. Notes on towing
atrailer
General notes Trailer towing is not permissibleont
he following
models:
R Mercedes AMG C63
R Mercedes AMG C63S
When towing atrailer, set the tyre pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 356).
On vehicles without level control, the height of
the ball coupling will alter according to the load
placed on the vehicle. If necessary, use atrailer
with aheight-adjustable drawbar.
You will find fitting dimensions and loads under "Technical data" (Y page 378). Driving tips Observe the notes on ESP
®
trailer stabilisation
(Y page 74).
The maximum permissibles peed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissibler ear axle load is increased
when towing atrailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 378). If you utilise any of the
added maximum rear axle load when towing a
trailer, the vehicle/trailer combination may not
exceed amaximum speed of 100 km/h for rea-
sons concerning the operating permit. This also applies in countries in which the permissible
maximum speed for vehicle/trailer combina-
tions is above 100 km/h.
When towing atrailer, your vehicle's handling
characteristics will be different in comparison to
when driving without atrailer and it will con-
sume more fuel.
Change into alower gear in good time on long
and steep downhill gradients.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine, so
less braking will be required to maintain vehicle speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain agreater distance to the vehicle in
front than when driving without atrailer.
R Avoid braking abruptly.Ifp ossible,brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The valuesg iven for gradient-climbing capa-
bilities from astandstill refer to sea level.
