General information
Only use towing equipment that has
been approved for your vehicle.
Vehicles with natural gas engine may
require special towing equipment.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle.
Driving characteristics and towing tips
Before attaching a trailer, lubricate the coupling ball. However, do not do so if a stabiliser, which acts on the
coupling ball, is being used to reduce
snaking movements.For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1300 kg the use of a stabiliser is
strongly recommended when driving
above 80 km/h.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 190.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.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 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
3 180.
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.

Accessories and vehiclemodifications
We recommend the use of genuine
parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Any modification, conversion or other
changes made to standard vehicle
specifications (including, without
limitation, software modifications,
modifications of the electronic control units) may invalidate the warrantyoffered by Opel. Furthermore, such
changes may impact fuel
consumption, CO 2 emissions and
other emissions of the vehicle and
cause the vehicle to no longer
conform to the type approval,
impacting the validity of your vehicle
registration.
