Practical information
Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest 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 performance. 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 Data" section for details
of the weights and towing loads which apply to your vehicle.
Side wind
)Take into account the increased sensitivity
to side wind.

Cooling

To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y controlled, its cooling capacity is not dependent on the engine speed.)
To lower the engine speed, reduce your speed.
The maximum towing load on a long slope
depends on the gradient and the outside
tem
perature.
In all cases, pay attention to the coolant
temperature.
) If this message is displayed, stop your vehicle as soon as it is safe to do so.


Braking

To w i ng a trailer increases the braking distance.


Tyres
)Check the tyre pressures of the towingvehicle and of the trailer, obser ving the recommended pressures.



Lighting
)Check the lighting and signalling on the
trailer.
I
f the message flashes slowly, wait for the engine to cool before topping up the level, if necessary.
If the messa
ge flashes rapidly, contact a CITROËN dealer or a qualified workshop
without delay.

Checks
petrol engines

The petrol engines are perfectly compatible
with E10 or E24 type petrol biofuels (containing10 % or 24 % ethanol), conforming to Europeanstandards EN 228 and EN 15376.
E85 type fuels (containing up to 85 % ethanol)
are reser ved exclusively for vehicles marketed
for the use of this type of fuel (BioFlex
vehicles). The quality of the ethanol mustcomply with European standard EN 15293.
For Brazil only, special vehicles are marketed
to run on fuels containing up to 100 % ethanol(E10 0 type).
Quality of the fuel used for
Diesel engines

The Diesel engines are per fectly compatible
with biofuels which conform to current andfuture European standards (Diesel fuel whichcomplies with standard EN 590 mixed with a
biofuel which complies with standard EN 14214)
available at the pumps (containing up to 7 %Fatty Acid Methyl Ester).
The B30 biofuel can be used in cer tain Diesel engines; however, this use is subject to strict
application of the special ser vicing conditions. Contact a CITROËN dealer or a qualified
workshop.
The use of any other type of (bio)fuel(vegetable or animal oils, pure or diluted,
domestic fuel...) is strictly prohibited (risk of
damage to the engine and fuel system). 1.6 litre petrol en
gines, even though they have
been designed to operate on 95 RON petrol,can accept 90 RON petrol without engine adjustments, but with a slight deterioration in performance.
2.0 litre petrol engines can accept 90 RON or higher petrol.
