Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F
T
o ensure that the 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.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic air
conditioning system.
F

O
perate the air conditioning system for
at least 5 to 10 minutes once or twice
a month to keep it in per fect working
o r d e r.
F

E
nsure that the passenger
compartment filter is in good condition
and replace the filter elements
periodically. We recommend the use of
a combined passenger compartment
filter. Thanks to its special active
additive, it helps both to purify the air
breathed by the occupants and to keep
the passenger compartment clean
(reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold air,
switch it off and contact the dealer network
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 and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
do not drive for too long with the ventilation
switched off.
Do not keep air recirculation set for an
extended period. If after an extended stop in sunshine, the
interior temperature is very high, first 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.
The condensation created by the air
conditioning results in a discharge of
water under the vehicle which is per fectly
normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
To maintain a comfortable temperature
in the passenger compartment, you can
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.

Headlamp dipping
Pull the stalk towards you to switch between
dipped and main beam headlamps or to
activate automatic headlamp dipping.
In the lighting off and sidelamps modes, the
driver can switch on the main beam headlamps
temporarily ("headlamp flash"), for as long as
the stalk is kept pulled.
Displays
Illumination of the corresponding indicator
lamp in the instrument panel confirms that the
lighting selected is on.

foglamps; the sidelamps will then switch off.
In good or rainy weather, by both day
and night, the front foglamps and the
rear foglamps are prohibited. In these
situations, the power of their beams may
dazzle other drivers. They should only be
used in fog or falling snow.
In these weather conditions, it is your
responsibility to switch on the foglamps
and dipped headlamps manually as the
sunshine sensor may detect sufficient
light.
Switch off the front and rear foglamps
when they are no longer necessary. Switching off of the lighting when the
ignition is switched off
On switching off the ignition, all of the
lamps turn off immediately, except for
dipped beam if automatic guide-me-home
lighting is activated.
Switching on the lighting after the
ignition is switched off
To reactivate the lighting control, rotate
ring A to the 0 position – lamps off, then to
the desired position.
On opening the driver's door a temporary
audible signal warns the driver that the
lighting is on.
It will go off automatically after a period of
time that depends on the state of charge
in battery (entering energy-saving mode).

Do not cover the rain sensor, linked with
the sunshine sensor and located in the top
centre of the windscreen, behind the rear
view mirror.
When using an automatic car wash, switch
off the automatic rain sensitive wipers.
In winter, it is advisable to wait until the
windscreen is completely clear of ice before
activating the automatic rain sensitive wipers.
Windscreen and headlamp

Checking and topping up this fluid should be
done with the engine off.
The fluid level should be checked
regularly, particularly during winter.
For more information on Checking levels and,
in particular, the screenwash/headlamp wash,
refer to the corresponding section.
Special position of the
windscreen wipers

Electronic stability control
(ESC)
Electronic stability control (ESC: Electronic
Stability Control) integrating the following
systems:
-
a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-
em

ergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-
d

ynamic stability control (DSC).
Definitions
Anti-lock braking system (ABS) and
electronic brake force distribution
(EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control in
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by a
reduction in the resistance of the pedal and an
increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
This system (also known as Traction Control)
optimises traction in order to limit wheel slip by
acting on the brakes of the driving wheels and
on the engine. It also improves the directional
stability of the vehicle on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Intelligent traction control
system ("Snow motion")
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control.
This system detects situations of poor sur face
grip that could make it difficult to move off
or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
When lit up continuously, this
warning lamp indicates a fault with
the ABS.
The vehicle retains conventional braking. Drive
carefully at moderate speed.
