Prolonged use of heated seats is not
recommended for people with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (e.g.
illness,
taking medication).
To keep the heated pad intact and to prevent
a short circuit:
–

Do not place heavy or sharp objects on the
seat.
–


Do not kneel or stand on the seat.
–


Do not spill liquids onto the seat.
–


Never use the heating function if the seat
is damp.
Heating and Ventilation
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the
exterior, via the grille located at the base of the
windscreen, or from the inside in air recirculation
mode.
Controls
Depending on version, the controls are
accessible in the touch screen or are
grouped together on the centre console panel.
Air distribution

1. Windscreen demisting/de-icing vents
2. Front side window demisting/de-icing vents
3. Adjustable and closable side air vents
4. Adjustable and closable central air vents
5. Air outlets to the front footwells
6. Air outlets to the rear footwells
7. Adjustable and closable air vents
Advice
Using the ventilation and air
conditioning system
►

T

o ensure that air is distributed evenly,
keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
► Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►

Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in good working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing a large load on a steep gradient
in high temperatures, switching off the air
conditioning increases the available engine
power, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.

belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.

Advice
The driver must ensure that passengers use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not invert the seat belt buckles, as they
will not fulfil their role properly.
To ensure the proper functioning of the belt
buckles, make sure that there are no foreign
bodies present (e.g.
a coin) before fastening.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible over the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
At the front, adjusting the position of the
seat belt may require the seat height to be
adjusted.
In order to be effective, a seat belt must:
–

be tightened as close to the body as
possible.
–


be pulled in front of you with a smooth
movement, checking that it is not twisted.
–


must only be used to secure one person.
–


not show signs of tearing or fraying.
–


not be changed or modified, in order to
avoid affecting its performance.
Recommendations for children
Use a suitable child seat if the passenger
is less than 12 years old or shorter than 1.5
metres.

82
Safety
Never use the same seat belt to secure more
than one child.
Never carry a child on your lap.
For more information on Child seats, refer to
the corresponding section.
Maintenance
In accordance with current safety
regulations, for all work on your vehicle's
seat belts, contact a qualified workshop with
the skills and equipment needed, which a
CITROËN
dealer is able to provide.
Have the seat belts checked regularly by a
CITROËN dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy water or
a textile cleaning product, sold by CITROËN
dealers.
Airbags
General information
System designed to help improve the safety
of the occupants sitting in the front seats and
the rear outer seats, in the event of a violent
collision. The airbags supplement the action
of the seat belts equipped with a force limiting
system.
Electronic detectors record and analyse the
front and side impacts sustained in the impact
detection zones:
–

In the event of violent impact, the airbags
deploy instantly and help better protect the
occupants of the vehicle; immediately after the
impact, the airbags deflate rapidly in order not
to hinder the visibility or the possible exit of the
occupants.
–


In the event of a slight impact, a rear impact
and under certain rollover conditions, the airbags
may not deploy; only the seat belt helps to
protect you in these situations.
The seriousness of the impact depends on the
nature of the obstacle and the speed of the
vehicle at the moment of collision.
The airbags do not operate when the
ignition is switched off.
This equipment will only deploy once. If a
second impact occurs (during the same or a
subsequent accident), the airbag will not be
deployed again.
Impact detection zones
A. Front impact zone
B. Side impact zone
When one or more airbags are deployed,
the detonation of the pyrotechnic charge
incorporated in the system makes a noise and
releases a small quantity of smoke.
This smoke is not harmful, but sensitive
individuals may experience irritation.
The detonation noise associated with the
deployment of one or more airbags may result
in a slight loss of hearing for a short time.

84
Safety
In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting position.
Fasten your seat belt and position it correctly.
Do not place anything between the occupants
and the airbags (e.g.
child, animal, object), do
not fix or attach anything near or in the path of
the airbags, as this could cause injuries when
they are deployed.
Never modify the original definition of the
vehicle, particularly in the area directly around
the airbags.
Even if all of the precautions mentioned are
observed, a risk of injury or of minor burns to
the head, chest or arms cannot be ruled out
when an airbag is deployed. The bag inflates
almost instantly (within a few milliseconds)
then deflates within the same time,
discharging the hot gas via openings provided
for this purpose.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved seat covers
compatible with the deployment of these
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (e.g.
clothing) as this could cause
injuries to the chest or arm when the airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof.
Child seats
The legislation on carrying children is specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
–

In accordance with European regulations, all
children under the age of 12 or less than one
and a half metres tall must travel in approved
child seats suited to their weight , on seats
fitted with a seat belt or ISOFIX mountings.
–


Statistically
, the safest seats in your
vehicle for carrying children are the rear
seats.
–

A

child weighing less than 9 kg must travel
in the "rearward facing" position both in the
front and in the rear.

85
Safety
5It is recommended that children travel
on the rear seats of the vehicle:
–

"rearward facing" up to the age of 3,
–

"forward facing" over the age of 3.
Make sure that the seat belt is correctly
positioned and tightened.
For child seats with a support leg, ensure that
the support leg is in firm and steady contact
with the floor.
An incorrectly installed child seat in a vehicle compromises the child's safety 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 harness 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 vehicle seat. If
the passenger seat is adjustable, move it
forwards if necessary.
Remove the head restraint 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 once
the child seat has been removed.
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.
Use 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 sun's rays,
fit side blinds on the rear windows.
As a safety measure, do not leave:
–

A

child alone and unsupervised inside 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.
Child seat at the rear
Forward-facing or rearward-facing



► Move the vehicle's front seat forward and
straighten the backrest so that the legs of the
child in the forward-facing or rearward-facing
child seat itself do not touch the vehicle's front
seat.
►

Check that the backrest of the forward-facing
child seat is as close as possible to the backrest
of the vehicle's rear seat, and ideally in contact
with it.
Centre rear seat
A child seat with a support leg must never be
installed on the centre rear passenger seat .
