206Driving and operatingBy driving uphill, the temperature of
the coolant is increased. To reduce
heating, drive at a reduced speed and
pay attention to the coolant
temperature. If the control indicator
2 of the engine coolant temperature
gauge illuminates, stop the vehicle
and switch off engine as soon as
possible.
Trailer towing Trailer loadsThe 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 12%.
The permissible trailer load applies
up to the specified incline and at sea
level. Since engine power decreases
as altitude increases due to the airbecoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of 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
3 264.
When distributing the loads in the
trailer, heavy objects should be
placed as close as possible to the
axle.
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 vertical
coupling load, especially in the case
of heavy trailers. The vertical coupling load should never fall below 25 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
60 kg , the gross vehicle weight rating
must not be exceeded. If the
permissible rear axle load is
exceeded, a maximum speed of
60 mph applies.
Towing equipment Depending on version the vehicle canbe fitted with a detachable or a fixed
coupling ball bar.
Type ACaution
When operating without a trailer,
remove the coupling ball bar.

housing:
1. Slide the lamp housing forward and remove it at the back. It may
help to use a screwdriver to lever
out the light housing from the
body. Wrap the tip of the
screwdriver with a cloth to prevent
paint damage.
