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 easily secured on the two 
rings A.
Some also have an upper strap  which is 
attached to ring B .
"ISOFIX " mountings
Your vehicle has been approved in accordance 
with the latest  ISOFIX regulations.
The seats, shown below, are fitted with ISOFIX 
compliant mountings:

Advice
The incorrect installation of a child seat in 
a  vehicle compromises the protection of 
the child 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 forwards if necessary.
The head restraint must be removed 
before installing a
  child seat with 
a
  backrest on 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. Children at the rear
At rear seating positions, always leave 
sufficient space between the front seat 
and:
-
 
a "
 rear ward facing" child seat,
-
 
t
 he child's feet for a   child seat fitted 
"forward facing".
To do this, move the front seat for wards 
and, if necessary, straighten its backrest.
For optimal installation of the "forward 
facing" child seat, verify that its backrest is 
as close as possible to the backrest of the 
vehicle seat, if possible in contact with it.
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 
the country in which you are driving.
Deactivate the front passenger airbag 
when a "rear ward facing" child seat is 
installed on the front passenger seats.
Other wise, there is a
  risk of serious or 
fatal injury to the child if the airbag is 
deployed. 
Safety  
Page 127 of 316
125
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.
We recommend using a
  booster seat with 
a
  backrest, equipped with a   belt guide at 
shoulder level.
Additional protections
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.
As a
  safety precaution, do not leave:
-
 
a c
 hild or children alone and 
unattended in a
  vehicle,
-
 
a c
 hild or an animal in a   vehicle 
which is exposed to the sun, with the 
windows closed,
-
 
t
 he keys within reach of children inside 
the vehicle.

Driving advice
Observe driving regulations and remain vigilant 
whatever the traffic conditions.
Pay close attention to the traffic and keep your 
hands on the wheel so that you are ready to 
react at any time to any eventuality.
As a  safety measure, the driver should only 
carry out any operations that require close 
attention when the vehicle is stationary.
On a
  long journey, taking a   break every two 
hours is strongly recommended.
In difficult weather, drive smoothly, anticipate 
the need to brake and increase the distance 
from other vehicles.
Never leave the engine running in 
an enclosed area without adequate 
ventilation: internal combustion engines 
emit toxic exhaust gases, such as carbon 
monoxide. There is a
  risk of poisoning and 
death!
In very severe wintry conditions 
(temperatures below -23°C), to guarantee 
correct operation and the longevity of 
the mechanical elements of your vehicle 
(engine and gearbox), the engine must be 
left running for 4
  minutes before driving.
Important!
Never drive with the parking brake applied 
– Risk of overheating and damage to the 
braking system!
As the exhaust system of your vehicle 
is very hot, even several minutes after 
switching off the engine, never park or run 
the engine on inflammable sur faces (dry 
grass, fallen leaves, etc.) – Risk of fire!
Never leave a  vehicle unsuper vised with 
the engine running. If you have to leave 
your vehicle with the engine running, apply 
the parking brake and put the gearbox into 
neutral or position N or P , depending on 
the type of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded 
roads, as this could cause serious damage 
to the engine or gearbox, as well as to the 
electrical systems of your vehicle. If you are obliged to drive on a
  flooded road:
-  
c
 heck that the depth of water does not 
exceed 15   cm, taking account of waves that 
might be generated by other users,
-  
d
 eactivate the Stop & Start function,
-  
d
 rive as slowly as possible without stalling. 
In all cases, do not exceed 6   mph (10   km/h),
-  
d
 o not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety 
conditions allow, make several light brake 
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact 
a   CITROËN dealer or a   qualified workshop.

In case of towing
Driving with a trailer places greater 
d emands on the towing vehicle and 
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity  to wind.
Cooling
Towing a trailer on a slope increases the 
t emperature 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 towable load on an incline 
depends on the gradient and the exterior 
temperature.
In all cases, keep a
  check on the coolant 
temperature.
F
 
I
 f this warning lamp and the 
STOP warning lamp come on, 
stop the vehicle and switch off 
the engine as soon as possible.
New vehicle
Do not pull a   trailer before having driven at least 
approximately 620
 
miles (1,000
 
 kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of 
engine braking is recommended.
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 Headlamp 
adjustment , refer to the corresponding 
section.
Certain driving or manoeuvring aid 
functions are automatically disabled if an 
approved towing system is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has 
a   secret code. When the ignition is switched 
on, this code must be recognised in order for 
starting to be possible.
This electronic engine immobiliser locks the 
engine management system a
  few moments 
after the ignition is switched off, and prevents 
starting of the engine by anyone who does not 
have the key.
In the event of a
  malfunction, you are informed 
by a
  message in the instrument panel screen.
If this happens, your vehicle will not start; 
contact a
  CITROËN dealer if required.

warns you when this is needed.
With petrol engines , after a
  cold start, 
preheating the catalytic converter can 
cause noticeable engine vibrations for 
anything up to 2
  minutes while stationary 
with the engine running (accelerated idle 
speed).
