Demisting/Defrosting
The demisting/defrosting of the door
mirrors works with the demisting/
defrosting of the rear screen.
For more information on Rear screen demisting/
defrosting, refer to the corresponding section.
Electrochrome interior rear
view mirror


The electrochrome system uses a sensor that
detects the level of exterior brightness and that
coming from the rear of the vehicle, in order to
automatically and gradually switch between day
and night usage.
To ensure optimum visibility while
manoeuvring, the mirror automatically
brightens when reverse gear is engaged.
The system is deactivated if the load in the
boot exceeds the height of the load space
cover or if the load space cover has items
placed on it.

Advice
Using the ventilation and air conditioning
system
►  To 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 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.
Servicing the ventilation and air
conditioning system
►  Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly.
We recommend using a composite passenger
compartment filter. Its specific active additive
helps protect against polluting gases and bad
smells.
►  To ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Manufacturer’s service schedule.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop &
Start system, refer to the corresponding
section.
Rechargeable hybrid vehicles
Intensive use of the air conditioning
reduces the vehicle range in Electric mode.

limit the delivery of cold air into the passenger
compartment.
On entering the vehicle, if the interior
temperature is much colder or warmer than
the comfort setting requested, there is no need
to alter the value displayed to more quickly
reach the required level of comfort. The system
automatically corrects the temperature
difference as quickly as possible.

Clean Cabin function
It includes the AQS (Air Quality System) and Clean
Air functions.
►  To activate/deactivate the function, press
button 7.
AQS function
Using an exterior pollution sensor, this function
automatically activates the recirculation of
interior air when a certain level of pollutants in
the exterior air is detected.
When the air quality returns to a satisfactory
level, recirculation of interior air is automatically
deactivated.
This function is not designed to detect unpleasant
odours. Recirculation is automatically activated when the
windscreen wash is used or when reverse gear is
engaged.
The function is inactive if the outside temperature
is below 5°C to prevent the risk of misting on the
windscreen and side windows.
Clean Air function
Using an interior pollution sensor, this function
detects fine particles (e.g. cigarette smoke,
mould, bacteria).
The management of the recirculation of interior
air makes it possible to return to a purified
passenger compartment in just a few minutes,
thanks to the passage of air through the high-
performance passenger compartment filter.
If the air quality appears to be reduced, contact a
dealer or a qualified workshop to change the high-
performance passenger compartment filter.
Air conditioning on/off
The air conditioning system is designed to
operate effectively in all seasons, with the
windows closed:
–

It lo

DS NIGHT VISION

This system identifies and signals the presence
of pedestrians and animals in the driver's field
of vision, in low exterior light conditions, using
an infrared camera located at the front of the
vehicle.
Select the "Night vision" display mode if you
want the infrared camera image to be displayed
constantly on the instrument panel. When the
conditions are met, an alert is triggered if there is
a risk of collision.
The permanent display disappears upon
switching off the ignition or if the conditions are
not met.
This system is a driving aid system that
cannot, under any circumstances, replace
the driver's assessment of night-time visibility
and traffic conditions.
In some cases, the differences in temperature
are insufficient and the system may not detect

Safety05
Curtain airbags
This system helps provide 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 dealer or a qualified
workshop to have the system checked.
The airbags may not be deployed in the event of a
serious impact.
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 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 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 dealer or
a qualified workshop.
