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 To lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F If the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.
Tyres
F Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling
on the trailer.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
Practical information
Towing with the RACIng version
Your vehicle cannot be fitted with a
towbar. The space occupied by the
sport diffuser prevents this.
