Coupling Socket Load; Rear Axle Load During Towing - Vauxhall VIVARO Owner's Manual

The p ermissible carav an/trailer loads for
your v ehicle are given in the vehic le p apers.
Unless otherwise stated, they are v alid for
gradients up to m ax. 12%.
The permissible cara van/trailer load should
be fully utiliz ed only by driv ers who are
adequately ex perienced in towing large
carava ns/trailers.
In higher elevations the engine output and
gradab ility may drop so that it may not be
possible for the permissible caravan/trailer
loads to be fully utiliz ed in m ountainous
territory.
The a ctual caravan/trailer load plus the
actual gross vehicle weight m ust not
exceed the maxim um perm itted towing
weight. For exam ple, if the perm itted gross
vehic le weight is utilised, the ca ra van/
trailer load must only be used until the
max imum permitted towing weight is
rea ched. The max imum permitted towing
weight is shown on the identifica tion plate,
see page 161.

Coupling socket load

The coupling sock et load is the load
exerted by the caravan/tra iler on the
coupling ball. It can be varied by cha nging
the weight distribution when loading the
caravan/trailer.
The max im um perm issible coupling sock et
loa d for the towing vehicle, stated on the
label, should alway s be a im ed for,
particula rly in the ca se of heavy carav ans/
tra ilers. The coupling socket loa d should
never be below 25 kg.
In the case of caravan/tra iler loads of
1200 k g or more, the c oupling socket load
should not be less than 50 kg.
When m easuring the coupling sock et load,
make sure that the draw bar of the loaded
caravan/trailer is at the same heig ht a s it
will be when the c aravan/trailer is coupled
with the towing v ehicle loaded. Particularly
important for trailers/caravans with
tand em axle.

Rear axle load during towing

When the carav an/trailer is coupled and
the towing vehic le fully loaded (including
all occupants), the perm issible rear ax le
loa d must not be exceeded.
