Towing bracket device
it is advisable not to drive at the maximum
permissibl
e speed in an unf
av
ourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the jerk-
ing that can be caused by locking of trailer
wheels. Select a low gear in due course be-
fore going down a steep downhill. This ena-
bles you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge

Stabilisation of the towing vehicle
and trailer
The stabilisation of the towing vehicle and
tr
ail
er t
ogether is an additional function of the
electronic stability control (ESC).
If the system detects that the trailer is sway-
ing, it intervenes automatically with the driver
steering recommendation to reduce the
swaying of the trailer.
Requirements for the stabilisation of the
towing vehicle and trailer
●
The vehicle is factory-equipped with a tow-
ing bracket or has been retro-fitted with a
compatible towing bracket.
●
The ESC and ASR are active. The control
lamp or is not lit up on the instrument
cluster.
●
The trailer is electrically connected to the
towing vehicle through the trailer power sock-
et.
●
The vehicle is travelling at over 60 km/h
(approx. 37 mph).
●
The maximum vertical load technically per-
missible is being utilised on the coupling de-
vice.
●
The trailer has a rigid draw bar.
●
If the trailer has brakes, it must be equipped
with a mechanical overrun brake.
WARNING
The enhanced security provided by the
electric stabilit
y control of the towing vehi-
cle and trailer should not lead you to take
any risks that could compromise your safe-
ty.
●
Adapt your speed and driving style at all
times t
o suit visibility, weather, road and
traffic conditions.
●
Accelerate with caution when the road is
slippery.
●
When adjusting any settings, stop accel-
erating.
WARNING
The electric stability control for the towing
v
ehicle and tr
ailer may not correctly de-
tect all driving conditions.
●
When the ESC is switched off, the stabili-
sation of the towing vehicle and trailer is al-
so switched off.
●
The stability system does not always de-
tect light and unstable trailers, so it may
not stabilise these correctly.
●
When driving on slippery surfaces with
poor grip, the trailer can even interfere with
the stability system.
●
Trailers with a high centre of gravity can
tip even without having previously swayed.
●
If a trailer is not attached, but the trailer
power socket is connected (e.g. installation
of a bicycle rack with lights), repeated au-
tomatic braking may occur in extreme driv-
ing conditions.
