Towing a trailer
ACCESSORIES

TOWING A TRAILER, CARAVAN, BOAT, ETC...
Refer to the administrative
documents (V5, ...) or to the Petrol
or Diesel "Dimensions, weights
and towed loads" section of chapter 9.
Distribution of loads: distribute the
load in the trailer so that the heaviest
loads are as close as possible to the
axle and the nose weight is close
to the maximum authorised without,
however, exceeding it.
Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.
Dimension A = 0.96 m
Driving advice
A towed vehicle must free wheel:
gearbox in neutral.
