3.8 Electronic Trailer Stabilisation (ETS plus)*
ETS Plus is a safety system that can be retrofitted for HOBBY cara
-
vans with a mechanical overrun brake. It automatically recognises if
the trailer starts to sway and, if necessary, can stabilise the car and
caravan by applying the caravan brakes.
A special MOT inspection is not required for installing
ETS Plus.
• ETS Plus operates within a temperature range of
-20°C to +65 °C.
• Do not reach into the moving parts of the ETS Plus
central unit!
• The steady plus on the 13-pin socket on the car
must be safeguarded by means of a fuse with at
least 15A but nor more than 20A.
• The increased level of safety provided by ETS Plus
should not, however, result in undertaking a safety
risk. The vehicle's speed must always be adjusted
to take weather, road and traffic conditions into
account.
• The limits imposed by the laws of physics cannot
be suspended by ETS Plus. Please keep this mind
when driving on wet or icy roads.
• Caravans with a high centre of gravity may turn
over before they begin to sway.
• No improper modifications may be/have been
made to the brake system as this could interfere
with the function of the ETS Plus.
The ETS Plus system makes use of an LED on the A
frame to indicate whether the connection to the car
has been carried out correctly. Please refer also to the
manufacturer's separate operating instructions.
• When driving downhill on a mountain pass, check
to ensure that the brakes are cooled sufficiently.
• Put the tow vehicle into a lower gear and drive
downhill at slow speed.
• Stretch the car and trailer as often as possible to
prevent the caravan from continuously bumping
into the car.
• Always make use of service areas and lay-bys to give
the brakes a chance to cool off.
Please read the separately enclosed operating manu-
al of the axle/brake manufacturer (Knott).
