Sand
This mode allows little spin on the two driving
wheels at the same time to allow the vehicle to
move forward and limit the risks of getting stuck
in the sand.
(mode active up to 75 mph (120 km/h))
Do not use the other modes on sand as
the vehicle may become stuck.
Recommendations
The vehicle is designed principally to
drive on tarmac roads, but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road driving
such as:
–

driving on t
errain which could damage the
underbody or strip away components (fuel
pipe, fuel cooler, etc.) due to obstacles or
stones in particular,
–

driving on t
errain with steep gradients and
poor grip,
–

cro
ssing a waterway.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat belt
on the chest of the occupant, thus improving their
protection.
In the event of an impact
Depending on the nature and seriousness
of the impacts, the pyrotechnic device may
trigger before and independently of airbag
deployment. Deployment of the pretensioners
is accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt system
checked, and if necessary replaced, by a dealer
or a qualified workshop.
Front seat belts
The front seat belts are fitted with a pyrotechnic
pretensioning system and a force limiting system.
Rear seat belts

Each of the rear seats has a three-point seat belt
with inertia reel.
The outer seats are fitted with a pyrotechnic
pretensioning and force limiting system.
Fastening
►  Pull the strap, then insert the tongue in the
buckle.
►  Check that the seat belt is fastened correctly
by pulling the strap.
Unlocking
►  Press the red button on the buckle.
►  Guide the seat belt as it is reeled in.

Advice
The driver must ensure that passengers
use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not interchange the seat belt buckles, as
they will not fulfil their role fully.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible on the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
In order to be effective, a seat belt:
–

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
Use a suitable child seat if the passenger
is less than 12 years old or shorter than one
and a half metres.
Never use the same seat belt to secure more
than one child.
Never carry a child on your lap.
For more information on Child seats, refer to
the corresponding section.
Maintenance
In accordance with current safety
regulations, for all repairs on your vehicle's
seat belts, go to a qualified workshop with the
skills and equipment needed, which a dealer is
able to provide.

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.

74Safety05
The front passenger airbag must be
deactivated before installing a rearward
facing child seat. Otherwise, the child risks
being seriously injured or killed if the airbag is
deployed.


Warning label - Front passenger airbag

You must comply with the following instruction,
reminded by the warning label on both sides of
the passenger sun visor:

can occur.
Deactivating the front
passenger airbag
For your child’s safety, the front
passenger airbag MUST be deactivated
when a "rearward facing" child seat is
installed on the front passenger seat.
Otherwise, the child would be exposed to the
risk of death or serious injury in the event of
airbag deployment.
Vehicles not equipped with a
deactivation/reactivation control
