data" section to find out whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towin gatrailer,
the vehicle/trailer combination may not
exceed amaximum speed of 100 km/ hfor
reasons concerning the operatin gpermit.
This also applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towin gatrailer, your vehicle's handling
characteristic swill be differen tincomparison
to when driving without atrailer.
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 strongc rosswinds
R demands more sensitive steering
R consumes more fuel
On long and steep downhill gradients, you
must shift to alower gear in good time, or on
vehicles with automatic transmission, select
the shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
Driving tips R
Maintain agreater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from astandstill refer to sea level. When driving in mountainous areas,
notet hat the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. Folding out the ball coupling
Before you can tow atrailer with your vehicle,
you must fold out the ball coupling.
The release wheel is located behind the left-
hand side trim panel in the boot. G
WARNING
Make sure that the ball coupling is engaged,
either in its folded-out or folded-in position,
and that the indicator lamp is off.
Do not turn the release wheel when atrailer
is coupled up. Otherwise, the trailer might
detach. X
To open the cover: turn handle:anti-
clockwise and fold down cover ;.206

WARNING
Do not disconnect atrailer with an engaged
overrun brake. Otherwise, your hand could
become trapped between the bumper and
trailer drawbar.
X Make sure that the transmission is in posi-
tion P.
X Apply the parking brake.
X Position the trailer level behind the vehicle.
X Couple up the trailer.

nect the trailer cable. Make sure that nobody
is in the vicinit yofthe wheel arch or the
underbody. You could otherwise trap yourself
or others.
As soon as you decouple the trailer, the unla-
den vehicle rises slightly. Make sure that you
or others are not injured in the process.
! Do not disconnect atrailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound-
ing of the overrun brake.

eindicator for LED lamps
i If LED lamps are fitted in the trailer, an
error message may appear in the multi-
function display even if ther eisnofault. The
reason for the error message may be that
the curren thas falle nbelow the minimum
of 50 milliamperes (mA).
To ensure reliable operation of the bulb failure
indicator, each LED chain in the trailer lighting
must be guaranteed aminimum curren tof
50 mA. Trailer with 7-pin connector
General information If your trailer has
a7-pin connector, you can
connectittot he 13-pin socket on the ball
coupling using an adapter or, if necessary, an
adapter cable. Bothoft hese can be obtained
at aq ualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre.
