6.3 Trailer safety
Functional explanation
•
Unbraked trailers (up to 750 kg) are fitted with an arrester
cable.
•
The arrester cable prevents the trailer from coming
uncoupled from the car in the event of the trailer coupling
disconnecting.
•
Braked trailers (from 750 kg to 3500 kg) are fitted with a
safety cable.
•
In the event of the trailer coming unhooked, the safety
cable will trigger automatic braking.
Driving without the arrester / safety cable attached is
prohibited by law!
Attaching the arrester / safety cable incorrectly is dan-
gerous and can result in fines in other countries!
Make sure the safety cable loop is sufficiently long to
allow cornering.
State of technology:
The safety cable may not be laid in a loop over the trailer cou-
pling. Where technically possible, it should be attached through a
ring or an existing drilled hole in the coupling.
The snap hook on the safety cable is hooked into the pre-mount-
ed ring on the body, thus securing the trailer.
The car coupling as a mechanical coupling device must be state of
the art (Directive ECE-R55).
The manufacturers of brackets must include attachment points
for secondary couplings (arrester / safety cable) or provide devic-
es which ensure that the trailer comes to a standstill in the event
that it comes uncoupled.
Pay attention to the safety information and operating
instructions from the manufacturer of the trailer
coupling on the car.
Driving with arrester / safety cable incorrectly attached!
The arrester / safety cable could detach from the ball head while
driving. If it came uncoupled, the trailer would be unsecured and
can't be braked - risk of accidents!
►
Before setting off, check that the arrester / safety cable is
correctly and securely hooked into or threaded through a
fixed ring / drilled hole / mechanical device - tying a loop
around the ball head is inadequate!
►
If necessary, retrofit an additional attachment device for
the arrester / safety cable if you have an older model
coupling (according to Directive EEC 94/20).

Ball head couplings according to ECE-R55
Example: Coupling with ring
1. Ball head coupling
2. Ring
3. Snap hook, attached
Ball head couplings according to EEC 94/20
Example: Coupling with clamping device
1. Universal clamping device
►
If you have an older model coupling, retrofit a universal
clamping device (1) according to EEC 94/20.
Pay attention to the installation instructions to mount
the universal clamping device correctly (# 700.00986).
