–

must be tigh
tened as close to the body as
possible;
–

must be pulled in fron
t of you with a smooth
movement, ensuring that it is not twisted;
–

must only be used t
o secure one person;
–

must no
t show signs of tearing or fraying;
–

must no
t be changed or modified, in order to
avoid affecting its performance.
Recommendations for children

Lateral airbags

In the event of a serious side impact, this system
protects the driver and front passenger to
mitigate the risk of injury to the chest between
the hip and the shoulder.
At the front, each lateral airbag is fitted in the
seat backrest frame, door side. At the rear, each
lateral airbag is fitted in the rear pillar.
Deployment
The lateral airbags are deployed on one side in
the event of a serious side impact applied to all or
part of the side impact zone B.
The lateral airbag inflates between the hip
and shoulder of the vehicle's occupant and the
corresponding door panel.
Curtain airbags
System contributing towards greater protection
for the driver and passengers (with the exception
Have your seat belts checked regularly by a
dealer or a qualified workshop, particularly if
the straps show signs of damage.
Clean the seat belt straps with soapy water or
a textile cleaning product, sold by dealers.
Airbags
General information
System designed to help improve the safety of the
occupants sitting in the front seats and the rear
outer seats, in the event of a violent collision. The
airbags supplement the action of the seat belts
equipped with a force limiting system.
Electronic detectors record and analyse the
front and side impacts sustained in the impact
detection zones:
–
In the e
vent of violent impact, the airbags
deploy instantly and help better protect the
occupants of the vehicle; immediately after the
impact, the airbags deflate rapidly in order not
to hinder the visibility or the possible exit of the
occupants.
–

In the e
vent of a slight impact, a rear impact
and under certain rollover conditions, the airbags
may not deploy; only the seat belt helps to protect
you in these situations.
* For more in formation on Deactivating the front passenger airbag, refer to the corresponding section.
The seriousness of the impact depends on the
nature of the obstacle and the speed of the
vehicle at the moment of collision.
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
When one or more airbags are deployed,
the detonation of the pyrotechnic charge
incorporated in the system makes a noise and
releases a small quantity of smoke.
This smoke is not harmful, but sensitive
individuals may experience slight irritation.
The detonation noise associated with the
deployment of one or more airbags may result
in a slight loss of hearing for a short time.
Front airbags

This system protects the driver and front
passenger in the event of a serious front impact,
in order to limit the risk of head and chest injuries.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger airbag is
fitted in the dashboard above the glove box.
Deployment
They deploy, except the front passenger airbag if
it is deactivated*, in the event of a serious front
impact to all or part of the front impact zone A.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the
steering wheel, driver's side, and the dashboard,
passenger's side, to cushion their forward
movement.

71Safety05
Lateral airbags

In the event of a serious side impact, this system
protects the driver and front passenger to
mitigate the risk of injury to the chest between
the hip and the shoulder.
At the front, each lateral airbag is fitted in the
seat backrest frame, door side. At the rear, each
lateral airbag is fitted in the rear pillar.
Deployment
The lateral airbags are deployed on one side in
the event of a serious side impact applied to all or
part of the side impact zone B.
The lateral airbag inflates between the hip
and shoulder of the vehicle's occupant and the
corresponding door panel.
Curtain airbags
System contributing towards 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
If this warning lamp comes on in the
instrument panel, you must 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 upright sitting position.
Fasten the seat belt ensuring it is correctly
positioned and adjusted.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), 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 only be
carried out by a dealer or a qualified workshop.
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 airbag 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.

Installing ISOFIX and i-Size
universal child seats
In compliance with European regulations, this
table indicates the possibilities of installing child
Rear seats
This system prevents the child seat from tipping
forward in the event of a front impact.
This ISOFIX mounting system provides fast,
reliable and safe fitting of the child seat in the
vehicle.
To secure the child seat to the TOP TETHER:
► Remove and stow the head restraint before
installing the child seat on this seat (refit it once
the child seat has been removed).
►  Pass the upper strap of the child seat behind
the seat backrest, between the head restraint
rods.
►  Secure the upper strap hook to ring B.
►  Tighten the upper strap.
When fitting an ISOFIX child seat to the
left-hand rear seat of the bench seat,
before fitting the seat, first move the centre
rear seat belt towards the middle of the
vehicle, so as to avoid the seat interfering with
the operation of the seat belt.
An incorrectly installed child seat
compromises the child's safety in the
event of an accident.
Strictly observe the fitting instructions
provided in the user guide supplied with the
child seat.
For information about the installation
possibilities for ISOFIX child seats in your
vehicle, refer to the summary table.

Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►  Monitor your environment and keep your
hands on the wheel to be able to react to anything
that may happen any time.
►  Drive smoothly, anticipate the need for braking
and maintain a longer safety distance, especially
in bad weather.
►  Stop the vehicle to carry out operations that
require close attention (such as adjustments).
►  During long trips, take a break every two
hours.
Important!
Never leave the engine running in a closed
space without sufficient ventilation.
Internal combustion engines emit toxic
exhaust gases such as carbon monoxide.
Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied. Risk of overheating and damage
to the braking system!
Do not park the vehicle or leave the engine
running on a flammable surface (dry
grass, dead leaves, etc.). The exhaust system
of your vehicle is very hot, even several
minutes after the engine stops. Risk of fire!
Never leave a vehicle unattended with the
engine running. If you have to leave your
vehicle with the engine running, apply the
parking brake and put the gearbox into neutral
or position N or P (depending on the type of
gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to the
engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
►  check that the depth of water does not exceed
15 cm, taking account of waves that might be
generated by other users,
►  deactivate the Stop & Start function,
►  drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
►  do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when driving,
the driver should pay particular attention.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during charging
to cool the on-board charger and the traction
battery.
On the inside
During use, you may hear certain perfectly normal
noises specific to electric vehicles, such as:
–

Traction ba
ttery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
– Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
