Towing Equipment - Vauxhall 2010 Astra Owner's Manual

The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients
up to max. 12 %.
The permitted trailer load applies up
to the specified incline and up to an
altitude of 3300 ft above sea level.
Since engine power decreases as
altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 %
for every 3300 ft of additional altitude.
The gross train weight does not have
to be reduced when driving on roads
with slight inclines (less than 8 %, e.g.
motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 187.
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
60 kg, the gross vehicle weight rating
may be exceeded by 60 kg. If the
permissible rear axle load is
exceeded, a maximum speed of
60 mph applies.
