to adjust.
►  Return the control to the central position.
As a safety measure, the mirrors should

to correctly judge the distance of vehicles
approaching from behind.
Manual folding
The mirrors can be folded manually (parking
obstruction, narrow garage, etc.).

Electric folding
If the vehicle is so equipped, the mirrors can
be folded electrically from the inside, with the
vehicle parked and the ignition on:

push it firmly to latch it home.
►  Check that the red indicator is no longer
visible in the release grip 1.

passengers in the event of sudden braking or
an accident.
The contents of the boot may be thrown
forward - risk of serious injury!
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 "Air conditioning" touch screen menu or
are grouped together in the control panel on the
centre console.
Air distribution

1. Windscreen demisting/defrosting vents
2. Front side window demisting/defrosting 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
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

44Ease of use and comfort03
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 perfect working order.
►  If the system does not produce cold air,
switch it off and contact a dealer or a qualified
workshop.
When towing the maximum 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. Thanks to its special
active additive, this type of filter helps to
purify the air breathed by the occupants
and keep the passenger compartment clean
(by reducing allergic symptoms, unpleasant
odours and greasy deposits).
►  To ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
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, refer
to the corresponding section.
Manual air conditioning
