Additional methods of restraint:
to the front seat belts
mETHOds Of REsTRAINT IN AddITION TO THE fRONT sEAT BELTs (1/4)
Depending on the vehicle, they may
comprise :
– seat belt inertia reel pretension -
ers;
– chest-level load limiter;
– anti-submarining air bags;
– air bags for driver and front pas -
senger.
These systems are designed to act in-
dependently or together when the vehi-
cle is subjected to a frontal impact.
Depending on the severity of the
impact, the system can trigger:
– seat belt locking;
– the inertia reel pretensioner to adjust
seat belt slack;
– the anti-submarining air bag to pin
the occupant into his seat;
– the low volume front air bag;
– the large volume front air bag.
pretensioners
The pretensioners hold the seat belt
against the body, holding the occupant
more securely against the seat, thus in-
creasing the seat belt’s efficiency.
In the event of a severe frontal impact
and if the ignition is switched on, the
system may engage the following de -
pending on the force of the impact:
– the pretensioner 1 which retracts the
seat belt immediately;
– the anti-submarining air bag.
– Have the entire restraint
system checked following
an accident.
– No operation whatso -
ever is permitted on any part of
the system (pretensioners, air
bags, computers, wiring) and the
system components must not
be reused on any other vehicle,
even if identical.
– To avoid incorrect triggering of
the system which may cause
injury, only qualified personnel
from an approved dealer may
work on the pretensioner and air
bag system.
– The electric trigger system may
only be tested by a specially
trained technician using special
equipment.
– When the vehicle is scrapped,
contact an approved dealer for
disposal of the pretensioner and
air bag gas generators.

to the rear seat belts
mETHOds Of REsTRAINT IN AddITION TO THE REAR sEAT BELTs
Depending on the vehicle, they are
composed of:
– seat belt pretensioners built into
the inertia reels,
– force limiter.
These systems are designed to act in-
dependently or together when the vehi-
cle is subjected to a frontal impact.
There are two possibilities, depending
on the force of the impact:
– protection is provided by the seat
belt only;
– the pretensioner is triggered to rec -
tify seat belt slack.
Rear seat belt pretensioners
This system is only operational when
the ignition is switched on.
If the vehicle is subjected to a severe
frontal impact, a device retracts the
seat belt, pulling the seat belt tight
against the body and thus improving its
effectiveness.
force limiter
Above a certain severity of impact, this
mechanism is used to limit the force of
the belt against the body so that it is at
an acceptable level.– Have the entire restraint
system checked following
an accident.
– No operation whatso -
ever is permitted on any part of
the system (pretensioners, air
bags, computers, wiring) and the
system components must not
be reused on any other vehicle,
even if identical.
– To avoid incorrect triggering of
the system which may cause
injury, only qualified personnel
from an approved dealer may
work on the pretensioner and air
bag system.
– The electric trigger system may
only be tested by a specially
trained technician using special
equipment.
– When the vehicle is scrapped,
contact an approved dealer for
disposal of the pretensioner and
air bag gas generators.

AddITIONAL mETHOds Of REsTRAINT
The air bag is designed to complement the action of the seat belt. Both
the air bags and seat belts are integral parts of the same protection
system. It is therefore essential to wear seat belts at all times. If seat belts
are not worn, the occupants are exposed to the risk of serious injury in
the event of an accident. It may also increase the risk of minor superficial injuries
occurring when the air bag is deployed, although such minor injuries are always
possible with air bags.
If the vehicle should overturn or suffer a rear impact, however severe, the pre-
tensioners and air bags are not always triggered. Shocks to the underbody of the
vehicle, e.g. from pavements, potholes or stones, can all trigger these \
systems.
– No work or modification whatsoever may be carried out on any part of the air
bag system (air bags, pretensioners, computer, wiring harness, etc.), except
by qualified personnel from an approved dealer.
– To ensure that the system is in good working order and to avoid accidental trig-
gering of the system which may cause injury, only qualified Network personnel
may work on the air bag system.
– As a safety precaution, have the air bag system checked if your vehicle has
been involved in an accident, or is stolen or broken into.
– When selling or lending the vehicle, inform the user of these points and hand
over this driver’s handbook with the vehicle.
– When scrapping your vehicle, contact your approved dealer for disposal of the
gas generator(s).
Operating faults
Warning light 1 will light up on the in -
strument panel when the ignition is
turned on and then go out after a few
seconds.
If it does not come on when the ignition
is switched on, or if it comes on when
the engine is running, there is a fault
with the system (air bags, pretension -
ers, etc.) in the front and/or rear seats.
Contact your approved dealer as soon
as possible. Your protection will be re-
duced until this fault is rectified.
1
All of the warnings below are given so that the air bag is not obstructed in any
way when it is inflated and also to prevent the risk of serious injuries caused
by items which may be dislodged when the air bag inflates.

No modifications what -
soever are permitted on
any part of the fuel supply
system (computers, wiring,
fuel circuit, injector, protection
covers, etc.) as this may be danger-
ous (such work must be undertaken
by qualified Network personnel).
fUEL TANK (2/2)
persistent smell of
fuel
If you notice a persistent
smell of fuel you should:
– stop the vehicle as soon as traf-
fic conditions allow and switch off
the ignition;
– switch on the hazard warning
lights and ask your passengers
to leave the vehicle and to keep
away from traffic;
– contact an approved Dealer.
filling with fuel
With the ignition off, insert the nozzle to
open valve A and insert it fully before
turning it on to fill the fuel tank (risk of
splashing).
Keep the nozzle in this position through -
out the entire filling operation.
When the pump cuts out automatically
at the end of the filling procedure, a
maximum of two further filling attempts
may be made, as there must be suffi -
cient space in the fuel tank to allow for
expansion.
Make sure that no water enters the fuel
tank during filling. The valve A and its
surround must remain clean.
petrol versions
Using leaded petrol will damage the
antipollution system and may lead to a
loss of warranty.
To ensure that the fuel tank is not filled
with leaded petrol, the fuel tank filler
neck contains a restrictor fitted with a
foolproof system which only allows
the nozzle for unleaded petrol to be
used (at the pump).
v ehicle fitted with the stop and
start function
To fill up with fuel, the engine must
be stopped (and not on standby):
stop the engine by pressing the
engine stop button 1 (please refer
to the information on “Starting and
Stopping the engine” in Section 2).
