Vauxhall Combo Owner's Manual

The permissible caravan / trailer loads are 

vehicle-dependent and engine-dependent 

maximum values which must not be 

exceeded. The actual caravan / trailer load 

is the difference between the actual gross 

weight of the caravan / trailer and the 

actual coupling socket load with the 

caravan / trailer coupled. When the 

caravan / trailer load is being checked, 

therefore, only the caravan / trailer wheels 

– and not the jockey wheel – must be 

standing on the weighing apparatus. 
The permissible caravan / trailer loads for 

your vehicle are given in the vehicle 

documents. Unless otherwise stated, they 

are valid for gradients up to max. 12%. 

The permissible caravan / trailer load 

should be fully utilised only by drivers who 

are adequately experienced in towing 

large or heavy caravans / trailers. 
The permitted caravan / 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 because of the air becoming 

thinner, therefore reducing climbing ability, 

the permitted towing weight also decreases 

by 10 % for every 1000 metres of additional 

altitude. The towing weight does not have 

to be reduced when driving on roads with 

slight inclines (less than 8%, e. g. 

motorways). 
The actual caravan / trailer load plus the 

actual Gross Vehicle Weight of the towing 

vehicle must not exceed the maximum 

permitted towing weight. For example, if 

the permitted Gross Vehicle Weight is 

utilised, the caravan / trailer load must only 

be used until the maximum permitted 

towing weight is reached. The maximum 

permitted towing weight is shown on the 

identification plate – see page 196. 

The coupling socket load is the load 

exerted by the caravan / trailer on the 

coupling ball. It can be varied by changing 

the weight distribution when loading the 

caravan / trailer. 
The maximum permissible coupling socket 

load (50 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 caravans / trailers. The coupling 

socket load should never fall below 25 kg. 
When measuring the coupling socket load, 

make sure that the drawbar of the loaded 

caravan / trailer is at the same height as it 

will be when the caravan / trailer is coupled 

with the towing vehicle loaded. Particularly 

important for caravans / trailers with 

tandem axle. 

The permissible axle loads must not be 

exceeded.
