Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest items are as close as possible to
the axle and the nose weight approaches the maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing engine performance. Above
1 000 metres, the maximum towing load must
be reduced by 10 % of the GTW and so on for every 1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towing loads which apply to your vehicle.
Side wind
)Take into account the increased sensitivity
to side wind.

Cooling

To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y controlled, its cooling capacity is not dependent on the engine speed.)
To lower the engine speed, reduce your speed.
The maximum towing load on a long slope
depends on the gradient and the outside
tem
perature.
In all cases, pay attention to the coolant
temperature.
) If this message is displayed, stop your vehicle as soon as it is safe to do so.


Braking

To w i ng a trailer increases the braking distance.


Tyres
)Check the tyre pressures of the towingvehicle and of the trailer, obser ving the recommended pressures.



Lighting
)Check the lighting and signalling on the
trailer.
I
f the message flashes slowly, wait for the engine to cool before topping up the level, if necessary.
