Instructions
The driver must ensure that the passengers
use the seat belts correctly and that they are
all fastened before driving.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do not interchange the seat belt buckles as
they will not completely fulfil their role.
The seat belts are equipped with an inertia
reel which allows the strap length to adjust
automatically to your shape. The seat belt is
stowed automatically when not in use.
Before and after use, ensure that the seat belt
is reeled in correctly.
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.
The inertia reels have an automatic blocking
device at the time of a collision, during
sudden braking or if the vehicle turns over.
You can release the device by pulling the
strap firmly and then releasing it so that it
reels in slightly.In order to be effective, a seat belt must:
-
b e tightened as close to the body as
possible,
-

b
e pulled in front of you with a smooth
movement, checking that it does not twist,
-

b
e used to restrain only one person,
-

n
ot show any signs of cuts or fraying,
-

n
ot be converted or modified to avoid
affecting its performance.
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 the dealer network
is able to provide.
Have your seat belts checked regularly in
the dealer network 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 in the dealer
network.
After folding or moving a seat or a rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly. 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 person.
Never allow a child to travel on your lap.
For more information on Child seats
, refer to
the corresponding section.
In the event of an impact
Depending on the nature and seriousness
of the impact , the pyrotechnic device may
be deployed before and independent of the
airbags. Deployment of the pre-tensioners
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,
in the dealer network or by a qualified
workshop.

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.

Operating fault
If this warning lamp in the instrument
panel comes on, you must contact the
dealer network or a qualified workshop
to have the system checked. The
airbags might no longer deploy in a
crash.
Lateral airbags
This system protects the driver and front
passenger in the event of a severe side impact
to minimise the risk of injury to the chest,
between hip and shoulder.
Each lateral airbag is fitted in the seat backrest
frame, door side.
Impact detection zones
A.Front impact zone.
B. Side impact zone.
Deployment
The airbag is deployed unilaterally in the
event of a severe side impact covering all or
part of side impact zone B , perpendicular to
the longitudinal centreline of the vehicle on a
horizontal plane and directed from the outside
towards the inside of the vehicle.
The lateral airbag inflates between the hip
and shoulder of the front passenger and the
corresponding door trim 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.
Deployment
The airbag is deployed at the same time as
the corresponding lateral airbag in the event
of a serious side impact applied to all or part
of the side impact zone B , perpendicular to
the longitudinal centreline of the vehicle on a
horizontal plane and directed from the outside
towards the inside of the vehicle.
The curtain airbag inflates between the front or
rear occupant of the vehicle and the windows.
Malfunction
If this warning lamp in the instrument
panel comes on, you must contact the
dealer network or a qualified workshop
to have the system checked. The
airbags might no longer deploy in a
crash.
In the event of a minor impact or bump on
the side of the vehicle or if the vehicle rolls
over, the airbag may not be deployed.
In the event of a rear or front collision, the
airbag is not deployed.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000 metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2 minutes after the vehicle
comes to a stop, to facilitate its cooling.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a genuine DS
AUTOMOBILES towbar is used.
