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.

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.

Depending on the version you have,
this warning lamp comes on in the
instrument panel and/or in the seat belt
and passenger's front airbag warning
lamps display when the ignition is on
and until the airbag is reactivated.
To assure the safety of your child,
the passenger's front airbag must be
deactivated when you install a rear ward
facing child seat on the front passenger
seat.
Otherwise, the child would risk being
seriously injured or killed if the airbag
were deployed.Reactivating the passenger's
front airbag
When you remove the child seat, turn the
switch to the " ON" position to reactivate the
airbag and so assure the safety of your front
passenger in the event of an impact.
With the ignition on, this warning
lamp comes on in the seat belt and
passenger's front airbag warning
lamps display for approximately
one minute, if the passenger's front
airbag is activated.

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.
