Notes on trailer towing
Important safety notes G
WARNING
Installing an unsuitable ball coupling may
overload the trailer tow hitch and the rear
axle. This is particularly likely in the case of
longer or differently angled ball couplings.
Consequently, the driving characteristics
may be significantly impaired and the trailer
may detach. This presents the risk of an
accident or even fatal injuries!
Install only a ball coupling that adheres to
the permissible dimensions and is designed
for your intended purpose for towing a
trailer. Do not make any changes to the ball
coupling or the trailer tow hitch. G
WARNING
If you install a ball coupling other than the
one delivered with the vehicle, the trailer
tow hitch and the rear axle may be overloa-
ded. This applies especially if the ball cou-
pling in question is longer or angled differ-
ently. This could seriously impair the driving
characteristics and the trailer can come
loose. There is a risk of an accident. Only install the ball coupling delivered with
the vehicle or a ball coupling that is
designed to meet your trailer towing require-
ments. Do not modify the ball coupling or
the trailer tow hitch.
G
WARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driv-
ing and endanger other road users. There is
a risk of accident and injury, possibly even
fatal injuries.
Install and secure the ball coupling as
described in the ball coupling manufactur-
er's installation instructions. Make sure that
the ball coupling is correctly installed and
secured before every journey. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even roll-
over. There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combina-
tion by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
You can attach carrier systems such as bicycle
racks or load-bearing implements on the ball
coupling. The maximum load-bearing capacity
of 165 lb (75 kg

) applies when using carrier
systems on the ball coupling.
Always observe the operating instructions pro-
vided by the manufacturers of the trailer cou-
pling and the ball coupling.
Couple and decouple the trailer carefully.
When backing up the towing vehicle, make
sure nobody is standing between the vehicle
and the trailer.
A trailer which is incorrectly coupled to the
towing vehicle could break away. A correctly
coupled trailer must be positioned horizontally
behind the towing vehicle. 168
