METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS (1/4)
Depending on the vehicle, they are
composed of:
– seat belt inertia reel pretension-ers;
– central seat belt pretensioners;
– chest-level load limiter;
– airbags driver and passenger
front.
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 seat belt inertia reel pretensioner (which engages to correct seat belt
slack);
– the lap belt pretensioners to hold the occupant in his seat;
– the front airbag.
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 seat belt inertia reel preten- sioner 1 which instantly retracts the
seat belt;
– the lap seat belt pretensioner 2 on
the front seats.
– Have the entire restraint
system checked following
an accident.
– No operation whatso-
ever is permitted on any part
of the system (pretensioners,
airbags, computers, wiring) and
the system components must not
be reused on any other vehicle,
even if identical.
– Only qualified personnel from our Network may work on the airbags;
otherwise the system may trigger
accidentally and cause injury.
– 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
airbags gas generators.

METHODS OF RESTRAINT IN ADDITION TO THE REAR SEAT BELTS
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 whatsoever
is permitted on any part of the
system (air bags, electronic con-
trol units, wiring) and the system
components must not be reused
on any other vehicle, even if iden-
tical.
– Only qualified personnel from our Network may work on the air
bags; otherwise the system may
trigger accidentally and cause
injury.

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 occu-
pants are exposed to the risk of serious injury in the event of an accid\
ent. It may also increase the risk of minor super-
ficial injuries occurring when the air bag is deployed, although such mi\
nor injuries are always possible with air bags.
If the vehicle should overturn or suffer a rear impact, however severe, the pretensioners and air bags are no\
t 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, preten\
sioners, compu-
ter, wiring harness, etc.), except by qualified personnel from an approved\
dealer.
– To ensure that the system is in good working order and to avoid accidenta\
l triggering 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 o\
f the gas generator(s).
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.

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.
Vehicles with RENAULT card
With the card RENAULT in the pas-
senger compartment, press the start
button 4 without pressing any of the
pedals. Wait a few minutes before start-
ing. This will enable the fuel circuit to
be primed. If the engine does not start,
repeat the procedure.
If the engine does not start after several
attempts, please contact an authorised
dealer.
No modifications what-
soever are permitted on
any part of the fuel supply
system (electronic units,
wiring, fuel circuit, injectors, pro-
tective covers, etc.) as this may be
dangerous (unless undertaken by
qualified Network personnel).

Vehicles with key/remote control
– Put the ignition key in the “ON" 2po-
sition (please see the information on
the "Ignition switch" in Section 2) and
wait for a few minutes before start-
ing, to enable the fuel circuit to be
primed;
– turn the key to position “START"3. If the engine does not start, repeat the
procedure.
– If the engine does not start after sev- eral attempts, please contact an au-
thorised dealer.
