2014 MERCEDES-BENZ C-CLASS SALOON ESP

!
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling char-
acteristics. Adapt your driving style accord-
ingly. Maintain a safe distance. Drive care-
fully.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis- sible speed for your vehicle/trailer combina-
tion. Notes on towing a trailer
General notes Trailer towing is not permissible on the fol-
lowing models:
R C 180 BlueEFFICIENCY Edition
R C 220 BlueTEC BlueEFFICIENCY Edition
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for a max-
imum load; see the tyre pressure table in the fuel filler flap (Y page 432). On vehicles without level control, the height
of the ball coupling will alter according to the
load placed on the vehicle. If necessary, use a
trailer with a height-adjustable drawbar.
You will find fitting dimensions and loads
under "Technical data" (Y page 477).
When towing a trailer, the ECO start/stop
function is deactivated. The èECO sym-
bol appears yellow in the multifunction dis-
play. For further information on the ECO
start/stop function; see (Y page 186).
Driving tips Observe the notes on ESP
®
trailer stabilisa-
tion (Y page 82).
The maximum permissible speed for vehicle/ trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max- imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. See the "Technical
data" section to find out whether this applies
to your vehicle (Y page 478). If you utilise any
of the added maximum rear axle load when
towing a trailer, the vehicle/trailer combina-
tion may not exceed a maximum speed of
100 km/h for reasons concerning the oper-
ating permit. This also applies in countries in
which the permissible maximum speed for
vehicle/trailer combinations is above
100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer and it will
consume more fuel.
Change into a lower 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 284

Coupling up a trailer
X Make sure that the transmission is in posi-
tion P.
X Apply the electric parking brake.
X Position the trailer horizontally behind the
vehicle.
X Couple up the trailer.
X Establish the electric connection between
the vehicle and the trailer.
X Check that the trailer lighting system is
working.
X Push the combination switch upwards/
downwards and check whether the corre-
sponding turn signal on the trailer is flash-
ing.
A connected trailer is only recognised when the electrical connection is established
correctly and when the lighting system is
working properly. The functioning of other
systems, e.g. ESP ®
, PARKTRONIC, Active
Parking Assist, Active Blind Spot Assist or
Lane Keeping Assist also depends on this. Uncoupling a trailer
G
WARNING
If you uncouple a trailer with an engaged over- run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses a risk of injury.
Do not uncouple a trailer with an engaged
overrun brake. G
WARNING
Vehicles with level control:
If you disconnect the trailer cable, the vehicle is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneath the vehicle. This
poses a risk of injury.
Make sure that no-one is in the immediate
vicinity of the wheel arch or underneath the
vehicle when disconnecting the trailer cable. !
Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound- ing of the overrun brake.
! Remove the installed adapter cable
before folding in the ball coupling. Other-
wise, damage may occur to the rear
bumper and the adapter cable.
X Make sure that the transmission is in posi-
tion P.
X Apply the electric parking brake.
X Secure the trailer against rolling away.
X Remove the trailer cable and decouple the
trailer. Folding in the ball coupling
G
WARNING
If you release the ball coupling or it does not
engage correctly when folding in, it will swing out. Within pivoting range of the ball coupling,
there is an increased risk of an accident and
injury.
Only release the ball coupling if the pivoting
range is unobstructed. Always make sure that the ball coupling engages when folding in.
Fold the ball coupling back in if you are not
using the trailer tow hitch. X Make sure that the vehicle is stationary and
the trailer cables are disconnected.
X Place the protective covering on the ball
coupling.
X Open the boot lid. 286
Towing a trailerDriving and parking

X
Pull release knob :until the ball coupling
unlocks.
The ball coupling folds down from under the rear bumper. The indicator lamp on the
release knob flashes.
Do not attempt to speed this process up by
applying additional pressure with your foot. The system could otherwise be mechani-
cally damaged. X
Press the ball coupling in the direction of
the arrow until it engages audibly behind
the bumper.
The indicator lamp on the release knob
goes out and the message in the multifunc-
tion display disappears. Trailer power supply
! You can connect accessories with a
power rating of up to 240 W to the perma-
nent power supply and with a power rating of up to 180 W to the power supply that is
switched on via the ignition lock. The trailer battery may not be charged from
the power supply.
When it leaves the factory, your vehicle's
trailer socket is equipped with a permanent
power supply and a power supply that is
switched on via the ignition lock.
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin
10.
The trailer's permanent power supply is
switched off in the event of low vehicle supply
voltage and after six hours at the latest.
You can find more information about fitting
the trailer electrics at a qualified specialist
workshop.
X To switch the connected power supply
on or off: turn the key in the ignition lock to
position 2or 0respectively (Y page 181). Bulb failure indicator for LED lamps
If LED lamps are fitted in the trailer, an error
message may appear in the multifunction dis-
play even if there is no fault. The reason for
the error message may be that the current
has fallen below the minimum of 50 mA.
To ensure reliable operation of the bulb failure indicator, each LED chain in the trailer lighting
must be guaranteed a minimum current of
50 mA. Trailer with 7-pin connector
General notes Trailer with 7-pin connector:
you can con-
nect to the 13-pin socket on the ball coupling
using an adapter or, if necessary, an adapter
cable. Both can be obtained at a qualified
specialist workshop. Towing a trailer
