Towing Equipment; Trailer Stability Assist - Opel 2016 Movano Owner's Manual

152 Driving and operating
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
3 201.
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 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.
In the case of trailer loads of
1200 kg or more, the vertical coupling
load should not be less than 50 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded (including
all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.

Towing equipment

Caution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment audible
warning
For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
signals.
The pitch of the audible warning will
change if a turn signal light on the
trailer or the towing vehicle fails.

Trailer stability assist

If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking
ceases. While the system is working,
keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Program (ESP) 3 138.
