Towing Equipment - Opel Automobile 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 loads apply up to
the specified incline and up to an
altitude of 1000 metres 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 1000 metres 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
3 181.
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 (vehicles with 1.2
engine: 45 kg, other engines: 55 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) for passenger vehicles
may be exceeded by 45 kg and the
gross vehicle weight rating by 50 kg
(on vehicles with 1.2 engine and
specific rear axle application: 30 kg).
For vans the permitted rear axle load
may be exceeded by 25 kg. The
permitted total load may be exceeded
by the following amounts with the
engines specified below:
A10XEP
A12XEL, A12XER,
Z12XEP
Driving and operating
Z13DTH, A13DTR
Z13DTJ, Z13DTE,
A13DTE, A13DTC
Trailer operation is not permitted for
vans with tyre size 215/45 R 17.
If the permitted rear axle load is
exceeded a maximum speed of
100 km/h applies. If lower national
maximum speeds are specified for
trailer operation, they must be
complied with.

Towing equipment

When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The coupling ball bar is stowed in
a bag in the spare wheel well and
secured to the lashing eyes in the
load compartment.
