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 trailers with a permitted gross

vehicle weight of more than 1400 kg

the use of a stabiliser is strongly

recommended when driving above

50 mph (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 3 215.

Trailer towing

Trailer loads

The permissible trailer loads are

vehicle-dependent 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 3300 ft (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 3300 ft

(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

3 199.

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 (85 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.
