Make sure that you have enough room
when cornering and avoid sudden
manoeuvres.
If the caravan / trailer starts to sway, drive
more slowly, do not attempt to correct the
steering and brake sharply if necessary.
If full-on braking is required, depress the
brake pedal as hard as possible.
Remember that the braking distance for
vehicles towing caravans / trailers with and
without brake is always greater than that
for vehicles not towing a caravan / trailer.
When driving downhill, towing a caravan /
trailer subjects the brakes to a heavier load
than normal. For this reason, select the
same gear as when driving uphill and drive
at a similar speed.
Easytronic 3 in Automatic mode will
automatically select the driving
programme with optimum engine braking
effect.

The cooling fan is electrically operated. Its
cooling power is therefore independent of
the engine speed.
Since a considerable amount of heat is
generated at high engine speeds and less
at slower speeds, do not shift down when
climbing hills whilst the vehicle is still coping
with the gradient in the higher gear.
Diesel engine: on gradients of 10% or more,
do not drive faster than 20 mph (30 km/h)
in first gear or 30 mph (50 km/h) in second
gear.
