Any work or modification
to the engine immobiliser
(electronic units, wiring,
etc.) may be dangerous. It
must be carried out by a qualified
RENAULT technician.
ENGINE IMMOBILISER
This prevents the vehicle being
driven by anyone not in possession
of the vehicle’s RENAULT card.
The vehicle is automatically
protected a few seconds after the
engine is switched off.
Operating principle
When the engine is started, warning
light 1remains on for a few seconds
and then goes out (refer to the
information on starting the engine in
Section 2).
If the code is not recognised, the
card reader flashes rapidly and the
vehicle cannot be started.
Indicator lights
Vehicle protection indicator light
After the ignition has been switched
off, indicator light 1will flash and
the vehicle is protected.

 Following an accident, itis necessary to have the
entire restraint system
checked by a qualified
technician.
 No operation whatsoever 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.
 To avoid accidental triggering of the system which may cause
injury, only qualified Renault
Network personnel may work on
the pretensioner and airbag
system.
 Testing of the electrical trigger system may only be carried out
by a specially trained technician
using suitable equipment.
 When the vehicle is scrapped, contact your RENAULT Dealer for
disposal of the pretensioner and
airbag gas generators.
METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS
These are:
■ buckle pretensioners,
■ lap pretensioners (five-door
version only),
■ thorax load limiters,
■ driver and passenger front
airbags,
■ anti-submarining airbags (three-
door version only).
These systems are designed to act
independently or together when the
vehicle is subjected to a frontal
impact.
Depending on the severity of the
impact, the system can trigger:
- seat belt locking;
- the buckle pretensioner (which engages to correct seat belt slack);
- the lap belt pretensioner or the anti-submarining airbag to keep
the occupant in their seat, the “low
volume” frontal airbag and load
limiters;
- the “large volume” frontal airbag.
Pretensioners
The pretensioners hold the seat belt
against the body, holding the
occupant more securely against the
seat, thus increasing the seat belt’s
efficiency.
With the ignition switched on, if
there is a severe frontal impact and
depending on the force of the
impact, the system may engage the:
- piston 1which instantly retracts
the seat belt;
- piston 2on the front seats (for the
five door version),
or
- the anti-submarining airbag (for the three door version).

METHODS OF RESTRAINT IN ADDITION TO THE REAR SEAT BELTS
Depending on the vehicle, they
comprise:
■ seat belt pretensioners built into
the inertia reels,
■ load limiter.
These systems are designed to act
independently or together when the
vehicle is subjected to a frontal
impact.
There are two possibilities,
depending on the force of the
impact:
- protection is provided by the belt only;
- the pretensioner is triggered to rectify 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.
Load 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.

ADDITIONAL METHODS OF RESTRAINTAll the warnings below are given so that airbag activation is not obstru\
cted in any way and also to prevent the risk of
serious injuries caused by items which may be dislodged when the airbag \
inflates.The airbag is designed to complement the action of the seat belt. Both t\
he airbags and seat belts are integral parts
of the same protection system. It is therefore essential to wear a seat \
belt at all times. If seat belts are not worn, the
occupants are exposed to the risk of serious injury in the event of an a\
ccident. It may also increase the risk of
minor superficial injuries occurring when the airbag is deployed, althou\
gh such minor injuries are always
possible with airbags.
If the vehicle should overturn or in the event of a rear impact, however\
severe, the pretensioners and airbags are not
always triggered. These systems may, however, be triggered by impacts to the vehicle underbody, e.g. from kerbs,
potholes, stones, etc.
 Any operation on or modification to any part of the Airbag system (Ai\
rbags, pretensioners, electronic unit, wiring, etc.) is strictly prohibited (except by qualified RENAULT Network personnel).
 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 RENAULT Network personnel may work on the airbag system.
 As a safety precaution, have the airbag system checked if your vehicle h\
as been involved in an accident, stolen or broken into.
 When selling or lending the vehicle, inform the user of these points and\
hand over this handbook with the vehicle.
 When scrapping your vehicle, contact your RENAULT Dealer for disposal of the gas generator(s).
