General recommendations
Observe the legislation in force in your
c o unt r y.
Ensure that the weight of the towing
vehicle is higher than that of the towed
vehicle.
The driver must remain at the wheel of
the towed vehicle and must have a valid
driving licence.
When towing a vehicle with all four
wheels on the ground, always use an
approved towing bar; rope and straps
are prohibited.
When towing a vehicle with the engine
off, there is no longer any power
assistance for braking or steering.
In the following cases, you must always
call on a professional recovery service:
-

Driving advice
Distribution of loads
F distribute the load in the trailer so that the heaviest 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 per formance. 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
d
a
ta" section for details
of the weights and towing loads which apply to
your vehicle.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towing load on a long slope
depends on the gradient and the outside
temperature.
In all cases, pay attention to the coolant
temperature.
F

I
f this message is displayed, stop your
vehicle as soon as it is safe to do so.
Braking
Towing a trailer increases the braking distance.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the lighting and signalling on the t r a i l e r.
If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.
