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 ,

If you purchased your vehicle outside the
dealer network, we invite you to have a
dealer check the configuration of these
ser vices and, if desired, modify them to
suit your wishes.
In a multi-lingual country, configuration is
possible in the official national language
of your choice.
For technical reasons and in particular to
improve the quality of Telematic ser vices
services to customers, the manufacturer
reser ves the right to carry out updates to
the vehicle's on-board telematic system.
Emergency or assistance
call (type 2)
Localised Emergency Call
In an emergency, press this
button for more than 2 seconds.
The flashing green LED and
the voice message confirm that
the call has been made to the
"Localised Emergency Call" call

ASR/DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep these systems activated in
all conditions, and particularly in difficult
conditions.
The correct operation of these systems
depends on observation of the
manufacturer's recommendations, not
only about the wheels (tyres and rims),
braking and electronic components but
also the assembly and repair procedures
used in the dealer network.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.Seat belts
Front seat belts
The front seat belts are fitted with a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side impact.
Depending on the severity of the impact, the
pretensioning system instantly tightens the seat
belts against the body of the occupants.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of
the seat belt on the passenger’s chest, thus
improving their protection.

Seat belt not fastened/unfastened
warning lamp in the instrument
panel
When the ignition is switched on, this
warning lamp comes on in the instrument
panel if the driver and/or the front
passenger have not fastened their seat belt.
Above approximately 12 mph (20 km/h),
this warning lamp flashes for two minutes
accompanied by an audible signal of increasing
volume. Once these two minutes have elapsed,
this warning lamp remains on until the driver
and/or the front passenger fasten their seat belt.

Airbags
General information
This system contributes towards improving
the safety of passengers (with the exception
of the rear centre passenger) in the event of
violent collisions. The airbags supplement the
action of the seat belts fitted with force limiters
(all

except the centre rear passenger belt).
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
-

i
n the event of a serious impact, the airbags
are deployed instantly and contribute
towards better protection of the passengers
(with the exception of the rear centre
passenger); immediately after the impact,
the airbags deflate rapidly so that they
do not hinder visibility or the exit of the
passengers,
-

i
n the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
protection in these situations.
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.
The deployment of an airbag is
accompanied by a slight emission of
smoke and a noise, due to the detonation
of the pyrotechnic charge incorporated in
the system.
This smoke is not harmful, but sensitive
individuals may experience slight irritation.
The detonation noise associated with the
deployment of an airbag may result in a
slight loss of hearing for a short time.
Front airbags
Deployment
The airbags are deployed (except the passenger's
front airbag if it is deactivated) in the event of a
serious frontal impact to all or part of the frontal
impact zone A , in the longitudinal centreline of the
vehicle on a horizontal plane and directed from
the front to the rear of the vehicle.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the
steering wheel, driver's side, or the dashboard,
passenger's side, to cushion their for ward
movement.
This system protects the driver and front
passenger in the event of a severe frontal
impact in order to limit the risk of injury to the
head and chest.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger's airbag is
fitted in the dashboard above the glove box.

Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy saving mode
System that manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can
still use functions such as the audio
equipment, windscreen wipers, dipped
beam headlamps,
courtesy lamps, etc. for a
maximum combined period of thirty minutes.
This period may be greatly reduced if the
battery is not fully charged.
Switching to this mode
Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to the energy saving
mode and the active functions are put on
st a n d by.If the telephone was operated via
the touch screen at that moment, the
connection would be interrupted after
10


minutes.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
F
I
n order to restore the use of these functions
immediately, start the engine and let it run
for a few minutes.
The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.
The engine will not start if the battery is
discharged.
