Towing Equipment - Opel ASTRA Owner's Manual

192 Driving and operating
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 243.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
40 kg. If the permissible rear axle load
is exceeded, a maximum speed of
100 km/h applies.
