Advice
Children at the front
The legislation on carrying children on the 
front passenger seat is specific to each 
country. Refer to the legislation in force in 
your country.
Deactivate the passenger's front airbag 
when a rear ward facing child seat is installed 
on the front passenger seat.
Otherwise, the child risks being seriously 
injured or killed if the airbag is deployed.
Installing a booster seat
The chest part of the seat belt must be 
positioned on the child's shoulder without 
touching the neck.
Ensure that the lap part of the seat belt 
passes correctly over the child's thighs.
CITROËN recommends the use of a booster 
seat which has a back, fitted with a seat belt 
guide at shoulder level.
The incorrect installation of a child seat in a 
vehicle compromises the child's protection in 
the event of an accident.
Ensure that there is no seat belt or seat belt 
buckle under the child seat, as this could 
destabilise it.
Remember to fasten the seat belts or the 
child seat harnesses keeping the slack 
relative to the child's body to a minimum, 
even for short journeys.
When installing a child seat using the seat 
belt, ensure that the seat belt is tightened 
correctly on the child seat and that it secures 
the child seat firmly on the seat of your 
vehicle. If your passenger seat is adjustable, 
move it for wards if necessary.
At rear seating positions, always leave 
sufficient space between the front seat and:
- 
a rear ward facing child seat,
-  the child's feet for a child seat fitted 
forward facing.
To do this, move the front seat for wards 
and, if necessary, move its backrest into the 
upright position. For optimum installation of the forward facing 
child seat, ensure that the back of the child 
seat is as close as possible to the backrest 
of the vehicle's seat, in contact if possible.
You mst remove the head restraint before 
installing a child seat with backrest to a 
passenger seat.
Ensure that the head restraint is stored or 
attached securely to prevent it from being 
thrown around the vehicle in the event of 
sharp braking. Refit the head restraint when 
the child seat is removed.
As a safety precaution, do not leave:
- a child or children alone and 
unsupervised in a vehicle,
-  a child or an animal in a vehicle which 
is exposed to the sun, with the windows 
closed,
-  the keys within reach of children inside 
the vehicle.
To prevent accidental opening of the doors 
and rear windows, use the child lock.
Take care not to open the rear windows by 
more than one third.
To protect young children from the rays of 
the sun, fit side blinds on the rear windows.

"ISOFIX" mountings
Your vehicle has been approved in accordance 
with the latest ISOFIX regulations.
The outer rear seats are fitted with regulation 
ISOFIX mountings.
There are three rings for each outer rear seat:
- two lower rings A , located between the 
vehicle seat back and cushion, indicated by 
a marking,
-  an upper ring B , called the TOP 
TETHER , fixed to the rear shelf and 
located under a cover behind the head 
restraint behind the head restraint, for 
fixing the upper strap.
  It is indicated by a marking. There are three rings for each outer rear seat:
- 
two lower rings A , located between the 
vehicle seat back and cushion, indicated by 
a marking,
-  an upper ring C , called the TOP TETHER , 
fixed to the roof on the boot end and 
located under a cover, for fixing the upper 
strap.
  It is indicated by a marking.Saloon Tourer

To attach the child seat to the TOP TETHER:
- remove and stow the head restraint before 
installing a child seat on this seat (refit it 
once the child seat has been removed),
-  pass the strap of the child seat centrally 
between the head restraint rod apertures,
-  raise the T oP TETHER cover, located on 
the rear shelf (Saloon) or the roof (Tourer),
-  secure the upper strap fixing to the ring B 
or C ,
-  tighten the upper strap.
The T
oP TETHER is used to secure the 
upper strap of child seats that have one. This 
arrangement limits the for ward tipping of the 
child seat in the event of a front impact. The incorrect installation of a child seat 
in a vehicle compromises the child's 
protection in the event of an accident.
Observe strictly the fitting instructions 
provided with the child seat.
This ISOFIX mounting system provides fast, 
reliable and safe fitting of the child seat in 
your vehicle.
The ISOFIX child seats are fitted with 
two latches which are secured easily on the 
two rings A
, following installation of the guides 
(supplied with the seat).
Some also have an upper strap  which is 
attached to the ring B or C . For information on the possibilities for 
installing ISOFIX child seats in your 
vehicle, refer to the summary table.

when leaving the vehicle, even for a 
short time.
In the event of a serious impact,

Fuel tank
Capacity of the tank: approximately 71 litres*.
Low fuel level
When the low fuel level in the 
tank is reached, this warning 
lamp comes on in the instrument 
panel, accompanied by an 
audible warning and a message in the display 
screen. When it first comes on, there remains 
around 5 litres of fuel in the tank.
You must refuel to avoid running out of fuel.
F  Press at the top left corner, then pull on its 
edge. While you are refuelling, the engine must be 
stopped and the ignition switched off.
F 
Turn the key a quarter turn to lock and 
unlock the filler cap.
F  When refuelling, place the cap on hook A .
F  Fill the tank, but do not persist after the 
third cut-off ; this could cause your vehicle 
to malfunction.
For a petrol engine with a catalytic 
converter,  the use of unleaded fuel is 
compulsory.
The filler neck is narrower to ensure that only 
unleaded petrol nozzles can be put in.
Opening the fuel flap Refuelling
Additions of fuel must be of at least 
5 litres to be taken into account by the 
fuel gauge.
Opening the filler cap may create a 
noise of an inrush of air. This vacuum, 
which is entirely normal, is caused by 
the sealing of the fuel system.
With Stop & Start, never refuel with the 
system in STOP mode; you must switch 
off the ignition with the key.
* 55 litres for Slovakia.

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.
