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 Data" 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 trailer.
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.

When the symbol begins to flash
rapidly (approximately twice per
second), there is not much fuel
remaining in your tank (approximately
5 litres).
You must fill the tank to avoid running
out of fuel.
Fuel tank
Capacity of the tank: approximately 60 litres.
Low fuel level
Filling
A label, affixed on the inside of the flap,
reminds you of the type of fuel to be used
according to your engine.
More than 5 litres of fuel must be added in
order to be registered by the fuel gauge.
Location of the cap
When the low fuel level is reached,
this indication appears in the
instrument panel screen. When it first
comes on, you have approximately
10 litres of fuel remaining.
The symbol flashes slowly (approximately

Quality of the fuel used for
petrol engines
The petrol engines are per fectly compatible
with E10 type petrol biofuels (containing 10 %
ethanol), conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 % ethanol)
are reserved exclusively for vehicles marketed
for the use of this type of fuel (BioFlex
vehicles). The quality of the ethanol must
comply with European standard EN 15293.
For Brazil only, special vehicles are marketed
to run on fuels containing up to 100 % ethanol
(E100 type).
Quality of the fuel used for
Diesel engines
The Diesel engines are per fectly compatible
with biofuels which conform to current and
future European standards (Diesel fuel
which complies 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 certain Diesel
engines; however, this use is subject to strict
application of the special servicing 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 engines, 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.
