XI - Practical Information -> Towing a trailer for Your Citroen C4 Picasso SUV First Generation (2006-2013)

P R A C T I C A L I N F O R M AT I O N  
Driving with a trailer places greater  
demands on the towing vehicle and  
the driver must take particular care.  
) To lower the engine speed, re-  
duce your speed.  
The maximum towed load on a long  
incline depends on the gradient and  
the ambient temperature.  
Towbar suitable for the attachment  
of a trailer with additional lighting  
and signalling.  
In all cases, keep a check on the  
coolant temperature.  
Driving advice  
Distribution of loads  
) 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 ex-  
ceeding it.  
) If the warning lamp and  
the STOP warning lamp  
come on, stop the vehicle  
and switch off the engine  
as soon as possible.  
Air density decreases with altitude,  
thus reducing engine performance.  
Above 1 000 metres, the maximum  
towed load must be reduced by 10 %  
for every 1 000 metres of altitude.  
Braking  
Towing a trailer increases the brak-  
ing distance.  
To avoid overheating of the brakes  
on a long mountain type of descent,  
the use of engine braking is recom-  
mended.  
Refer to the "Technical Data" section  
for details of the weights and towed  
loads which apply to your vehicle.  
Your vehicle is primarily designed  
for transporting people and luggage,  
but it may also be used for towing a  
trailer.  
Tyres  
) Check the tyre pressures of the  
towing vehicle and of the trailer,  
observing the recommended  
pressures.  
We recommend the use of genuine  
CITROËN towbars and their har-  
nesses that have been tested and  
approved from the design stage  
of your vehicle, and that the t-  
ting of the towbar is entrusted to  
a CITROËN dealer or a qualied  
workshop.  
If the towbar is not tted by a  
CITROËN dealer, it is imperative  
that it is tted in accordance with the  
vehicle manufacturer's instructions.  
Side wind  
) Take into account the increased  
sensitivity to side wind.  
Lighting  
) Check the electrical lighting and  
signalling on the trailer.  
XI  
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.  
The rear parking sensors will be  
deactivated automatically if a gen-  
uine CITROËN towbar is used.
