ing are examples of reversing camera mes-
sages in the multimedi asystem.
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons ,animal sor
objects in rang ewhile manoeuvring and parking.
Unde rthe following circumstances, the revers-
ing camera will not function, or will function in a limite dmanner:
R if the boo tlid is open

R at nigh torinv ery dark places
R if the camera is exposed to very bright light
R if the are aislitby fluorescent bulb sorLED
lighting (the display may flicker)
R if there is asudde nchange in temperature,
e.g. when driving into aheated garag einwin-
ter R
if the camera lens is dirty or obstructed.

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.
