Towing a trailer
On the contrary, use a high gear to
lower the engine speed and reduce
your speed.
In all cases, pay attention to the
coolant temperature.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually.
Automatic adjustment
For vehicles with Xenon bulbs, and if
the change in load makes it necessary,
this system automatically corrects the
height of the beam after approximately
2 minutes. The driver is then assured
of having optimum lighting and not
causing a nuisance to other road
users.
In certain cases of particularly
arduous use (towing the
maximum load up a steep slope
in high temperatures), the engine
automatically limits its power. In this
case, cutting off the air conditioning
allows the engine power to be
recovered, and therefore the towing
speed to be signiﬁ cantly increased
(approximately 12 mph [20 km/h]
more). Sequential control of the
gearbox may also become unavailable. Lighting
Bicycle carrier
Refer to the "Identiﬁ cation
features" section of chapter 8. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 7.

If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.

Tyres: check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
Towbar
We recommend the use of original
CITROËN towbars, which have been
tested for endurance from the design
stage of your vehicle.
Towing equipment must be ﬁ tted in
accordance with the manufacturer's
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
the electrical connection. As this ﬁ tting
should be carried out by a professional,
we recommend that you entrust the
ﬁ tting of this equipment to a CITROËN
dealer.
In accordance with the general
instructions referred to above, we draw
your attention to the risk connected
with ﬁ tting a towbar or other electrical
accessory which is not recommended
by the CITROËN network. Fitting such
equipment could result in a failure
of your vehicle's electronic system.
Please contact a CITROËN dealer ﬁ rst
for further information. Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.
If you ﬁ t a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display's
conﬁ guration menu.

Fuel
CHECKS

LOW FUEL LEVEL Filling with fuel
The tank must be ﬁ lled with fuel with

the engine off .
- Open the fuel ﬁ ller ﬂ ap.
- Insert the key then turn it to the left.
- Remove the cap and attach it to the clip located on the inside of the
ﬂ ap.
It is usual to hear an air intake noise
when opening the cap as there is a
vacuum linked with the sealing of the
fuel circuit.
A label on the inside of the ﬂ ap
indicates which type of fuel to use.
More than 5 litres of fuel must be
added in order to be registered by the
fuel gauge.
If you ﬁ ll your tank, do not continue
after the third cut-off of the pump
nozzle. This could result in vehicle
malfunctions.
FILLING THE FUEL TANK
If the warning light ﬂ ashes, this
indicates a fuel gauge malfunction.
Consult a CITROËN dealer.
When the tank's minimum
level is reached, this warning
light comes on, accompanied
by the message "Fuel level
low" on the display. When
this warning light ﬁ rst comes on, you
have approximately 8 litres left,
depending on driving conditions and
the engine.
Fill up with fuel as soon as possible to
avoid running out.
Never continue to drive until you run
out of fuel as this could damage the
emission control and injection systems. The capacity of the tank is
approximately 18 gallons (
80 litres).
- After ﬁ lling the tank, lock the cap and close the ﬂ ap. When the fuel ﬁ ller ﬂ ap is open, a
system limits the opening of the
rear left sliding side door.
The key cannot be removed from the
cap's lock until the cap is reﬁ tted on the
tank.

DIESEL

Fuel
FUEL CIRCUIT DISARMED
In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine. The ﬂ ashing of this warning
light is accompanied by a
message on the display.
DIESEL REPRIMING
PUMP
If you should run out of fuel, it is
necessary to re-prime the circuit:
- ﬁ ll the fuel tank with at least ﬁ ve litres of diesel,
- squeeze and release the manual re-priming pump, under the bonnet
under the protective cover, until fuel
appears in the transparent pipe,
- operate the starter until the engine starts.
Check that there is no odour or
leakage of fuel outside the vehicle and
re-establish the fuel supply:
- switch off the ignition
(STOP position).
- remove the key.
- put the key back in the ignition.
- switch on the ignition and start.
Quality of the fuel used for
Diesel engines
The Diesel engines are perfectly
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. Consult a
CITROËN dealer.
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).

Opening the bonnet
OPENING THE BONNET
From inside:
- lift the cover located at the left foot of the passenger seat.
- pull the control upwards. “Bonnet open” warning
This warning is linked to the
alarm
option only.
With the engine running or the vehicle
moving, a graphic on the display,
accompanied by an audible signal,
warns you that the bonnet is not
properly closed.
From outside:
- lift the catch and raise the bonnet.
Bonnet strut
Secure the strut to hold the bonnet
open.
Before closing the bonnet, replace the
strut in its housing.
To close
Lower the bonnet and release it at the
end of its travel. Check that the bonnet
is properly locked.

114
Levels
Cooling system
Only use the ﬂ uid recommended by the
manufacturer.
Otherwise, you risk seriously damaging
your engine.
When the engine is warm, the
temperature of the coolant is controlled
by the engine fan. As this fan can
operate with the ignition key removed
and because the cooling system is
pressurised, wait for at least one hour
after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to
release the pressure to prevent any
risk of scalding. When the pressure
has dropped, remove the cap and top
up the level with coolant.
If ﬂ uid has to be added frequently,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible. Power steering fluid level
The vehicle must be parked on level
ground with the engine cold. Unscrew
the cap integrated with the gauge and
check the level which must be between
the MIN and MAX marks.
During regeneration of the particle
emission ﬁ lter, relay noise may be
heard under the fascia.
If the message is still displayed and
the service warning light remains on,
contact a CITROËN dealer.
Diesel additive level (Diesel with
particle emission filter)
When this occurs with the engine running,
this is due to the start of saturation of
the particle emission ﬁ lter (exceptionally
prolonged urban driving conditions: low
speed, long trafﬁ c jams, ...).
In order to regenerate the ﬁ lter, you are
advised to drive at a speed of more than
40 mph (60 km/h) as soon as possible,
when trafﬁ c conditions permit, for at
least ﬁ ve minutes (until the message
disappears and the service warning light
is switched off).
Topping up
The level must be between the MIN
and MAX marks on the expansion
bottle. If more than 1 litre of ﬂ uid is
required to top up the level, have the
system checked by a CITROËN dealer. Windscreen wash and headlamp
wash level
For best quality cleaning and for your
safety, we would advise that you use
products of the CITROËN range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a CITROËN dealer
without delay.
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake ﬂ uid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
ﬂ uid or coolant into drains or onto
the ground but into the containers
dedicated to this use at CITROËN
dealerships.
The minimum level of this
additive is indicated by
lighting of the service warning
light, accompanied by an
audible signal and a message
on the display.
