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.

Instructions
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting position.
Wear a correctly adjusted seat belt.
Do not leave anything between the occupants
and the airbags (a child, pet, object...), nor fix
or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly
around the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must be
per formed in the dealer network or by a
qualified workshop.
Even if all of the precautions mentioned
are obser ved, a risk of injury or of minor
burns to the head, chest or arms when an
airbag is deployed cannot be ruled out. 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.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 fit or attach anything to the steering
wheel or dashboard, this could cause injuries
in case of airbag deployment.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, contact the
dealer network.
Do not attach anything to or hang anything
from the seat backrests (clothes, etc.) as
this could cause injuries to the thorax or arm
when the lateral 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!
Such work must only be done in the dealer
network or by a qualified workshop.
Curtain airbags
Do not attach anything or hang anything to
the roof, as this could cause head injuries
when the curtain airbag is deployed.
If fitted to your vehicle, do not remove the
grab handles installed on the roof, they play a
part in securing the curtain airbags.

Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a specific code. When the ignition is switched
on, this code must be recognised to allow the
engine to be started.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.In the event of a fault, you are
informed by illumination of this
warning lamp, an audible signal
and/or the display of a message,
depending on version.
Starting/Switching off the
engine with the key
Ignition switch
It has 3 positions:
- position 1 (Stop): inserting and removing
the key, steering column locked,
-
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
-
position 3 (Starting) .
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reser ve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preser ve the remaining
battery charge. Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch
and could cause a malfunction.
Switching off the engine leads to a loss of
braking assistance.

workshop.
In temperate conditions, do not leave
the engine at idle to warm up but move
off straight away and drive at moderate
spe ed. Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), to guarantee

Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams,...).
The engine restarts automatically – START
mode – as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
Operation
Going into engine STOP mode
The " ECO" warning lamp comes on in
the instrument panel and the engine
goes into standby automatically:
- with a manual gearbox , at speeds below
12 mph (20 km/h) or when the vehicle is
stationary with the PureTech 130 petrol and
BlueHDi 115 and 120 Diesel versions, when
you place the gear lever in neutral and you
release the clutch pedal,
-

W
ith an automatic gearbox , when the
vehicle is stationary and when you press
the brake pedal or put the gear selector in
position N . If your vehicle is fitted with this
system, a time counter calculates
the time spent in STOP mode
during a journey. It resets to
zero every time the ignition is
switched on with the key or the
"START/STOP" button.
STOP mode does not affect the operation
of vehicle systems such as braking, power
steering...
Never refuel with the engine in STOP
mode; you must switch off the ignition with
the key or the "START/STOP" button.
Special cases: STOP mode not
available
STOP mode is not activated when:
- t he vehicle is on a steep slope (uphill or
downhill),
-

t
he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

t
he vehicle has not exceeded 6 mph (10
km/h) since the last engine start (with the
key or the "START/STOP" button),
-

t
he electric parking brake is applied or being
applied, -

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-
d
emisting is active,
-
c
ertain special conditions (battery charge,
engine temperature, braking assistance,
exterior temperature, etc.) require the
engine to be running to assure control of a
system.
In this case, the " ECO" warning
lamp flashes for a few seconds then
goes off.
