Misfuel prevention (Diesel)*
When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle. Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of
engine damage that can result from filling with the wrong fuel.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
Operation
It remains possible to use a fuel can to
fill the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel prevention device and pour
s l ow l y.
*

Depending on the country of sale.
Travelling abroad
As Diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.

Energy economy mode
System which manages the duration of use of
certain functions to conserve a sufficient level
of charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics
system, windscreen wipers, dipped beam
headlamps,
courtesy lamps, etc. for a
maximum combined duration of about forty
minutes.Switching to economy mode
A message appears in the instrument panel
screen indicating that the vehicle has switched
to economy mode and the active functions are
put on standby.
If a telephone call is being made at this
time, it will be maintained for around
10
minutes with the Bluetooth
® hands-
free system of your audio system.
Exiting economy mode
These functions are reactivated automatically
next time the vehicle is driven.
In order to restore the use of these functions
immediately, start the engine and let it run:
-

f
or less than ten minutes, to use the
equipment for approximately five minutes,
-

f
or more than ten minutes, to use the
equipment for up to approximately
thirty
m

inutes.
Let the engine run for the duration specified to
ensure that the battery charge is sufficient.
Do not repeatedly and continuously restart the
engine in order to charge the battery.
A flat battery prevents the engine from
starting.

Towing a trailer
Your vehicle is primarily designed for transporting people and luggage, but it may also be used for towing a trailer.
Side wind
F Take into account the increased sensitivity to side wind.
When towing
We recommend the use of genuine
CITROËN towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
and that the fitting of the towbar is
entrusted to a CITROËN dealer or a
qualified workshop.
If the towbar is not fitted by a
CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
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 towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
For more information on Weights , refer
to the corresponding section.
Driving with a trailer places greater
demands on the towing vehicle and the
driver must take particular care.
For more information on Driving
advice
, particularly when towing, refer
to the corresponding section.
You must observe the maximum trailer
weight, indicated on the registration
certificate or in the technical
specification for your vehicle. For more information on Weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.

Blanking cover
When towing, you must remove the blanking
cover in the front bumper as well as the bonnet
seal if fitted.
Contact a CITROËN dealer or a qualified
workshop for this.
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 electrical lighting and signalling on the trailer and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamps , refer to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
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 towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

Normal position
The flap 2 is in a horizontal position in the air
duct 3.
Snow position
F Push and rotate the knob 1 by 90 ° in the
direction of the arrow in order to position
the flap 2 in a vertical position in the air
duct 3 .
To return to the normal position, push the
knob
1 then rotate in the opposite direction.
It is essential to remove the very cold
protection when:
- the exterior temperature exceeds 10 °C.
- driving at speeds of over 75 mph (approximately 120 km/h).
Adjustable device which prevents the intake of snow particles, which could obstruct the air filter.

located at the bottom of the door frame. Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid any risk of injury
resulting from an automatic change to
START mode.
The location of the interior release lever
prevents opening of the bonnet while
the front left-hand door is closed.
This operation must only be carried out
when the vehicle is stationary.
Avoid opening the bonnet in strong
winds.
When the engine is hot, handle the
safety catch and bonnet stay with care
(risk of burns). Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing,
...) be limited.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.
