Access
Ensure that any luggage or accessories
carried on the roof bars do not interfere
with the movement of the sunroof.
Do not place heavy loads on the movable
glass panel of the sunroof.
If the sunroof is wet, following a shower
or washing the vehicle, wait until it is
completely dry before opening.
Do not operate the sunroof if it is covered by
snow or ice - risk of damage!
Use only plastic scrapers to remove snow or
ice from the sunroof.
Regularly check the condition of the
sunroof seals (e.g. presence of dust,
dead leaves).
If using a car wash, check first that the roof is
correctly closed and keep the high-pressure
jet at least 30 centimetres from the seals.
Never leave the vehicle with the sunroof
open.
Operation
When opening the sunroof fully, the movable
glass moves to a partially open position, then
slides over the roof. Any intermediate position is
possible.
Before operating the sunroof control

3consumption in turn decreases energy
consumption.
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.

Safety
5Front airbags

System that protects the driver and front
passenger in the event of a serious front impact,
limiting the risk of head and chest injury.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger airbag is
fitted in the dashboard above the glove box.
Deployment
They deploy, except the front passenger airbag
if it is deactivated*, in the event of a serious front
impact to all or part of the front impact zone A.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the
steering wheel, driver's side, and the dashboard,
passenger's side, to cushion their forward
movement.
* For more information on Deactivating the front passenger airbag, refer t\
o the corresponding section.
Lateral airbags

This system protects the driver and front
passenger in the event of a serious side impact,
limiting the risk of injury to the chest, between
the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, on the door side.
Deployment
The lateral airbags are deployed on one side in
the event of a serious side impact applied to all
or part of the side impact zone B.
The lateral airbag inflates between the chest of
the vehicle's occupant and the corresponding
door panel.
Curtain airbags
System contributing towards greater protection
for the driver and passengers (with the exception
of the rear centre passenger) in the event of a
serious side impact in order to limit the risk of
injury to the side of the head.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.
Deployment
It deploys simultaneously with the corresponding
lateral airbag in the event of a serious side
impact applied to all or part of the side impact
zone B.
The curtain airbag inflates between the front
and rear occupants of the vehicle and the
corresponding windows.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel. Contact a CITROËN dealer
or a qualified workshop to have the system
checked.
The airbags may not be deployed in the event of
a serious impact.

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 .

Driving
Adjusting the audible signal
(With MyCitroën Drive or MyCitroën
Drive Plus)
Pressing this button opens the window
for adjusting the volume of the audible
signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant, orange: close, red: very
close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of the
vehicle is below 6 mph (10
km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6 mph (10 km/h).
The sound emitted by the speaker (front or rear) locates the obstacle relative to
the vehicle, in front or behind it.
Side parking sensors

Using four additional sensors located on the
sides of the bumpers, the system records the
position of obstacles during the manoeuvre and
indicates them when they are located alongside
the vehicle.
Only fixed obstacles are indicated
correctly. Moving obstacles detected at
the beginning of the manoeuvre may be
indicated mistakenly, while moving obstacles
that appear alongside the vehicle but were
not previously recorded will not be indicated.
Objects memorised during the
manoeuvre will no longer be stored after
switching off the ignition.
Deactivation/Activation
