Air bags and seat belt pretensioners
88
The Clio II from now on will be fitted with a new 2nd generation passive safety assembly comprising :
- a driver’s front air bag with an SRP inflatable bag (unaltered),
- a new passenger’s front air bag (according to equipment) with a new S.R.P inflatable bag which is in-
compatible with old computers part number 77 00 426 752 (see following page),
- front pretensioners (unaltered),
- front seat belts specific to the
SRP programmed restraint system (unaltered),
- a new computer specific to this assembly (30 or 50 tracks according to equipment),
- a new driver’s and passenger’s side air bag assembly (according to equipment) with side impact sensor
fitted in the central pillar of the same side.
IMPORTANT
With this assembly ( SRP front air bags), the seat belts are connected to the air bag function.
The programmed restraint system for the seat belts is not calibrated in the same way according to whe-
ther they are mounted with an SRP air bag or not (the part number for each part must be checked before
being replaced).
On these vehicles, it is forbidden to fit an SRP seat belt on a seat not provided with an air bag .
For more information about the SRP seat belts, see the corresponding bodywork technical note.

IMPORTANT
For replacement, the new type of computer (A) can be fitted to vehicles fitted with a 1st or 2nd genera-
tion passenger air bag module (B) .
On the other hand, a 2
nd generation passenger air bag module (B) must not be fitted to a vehicle fitted
with a computer (A) of the 1st generation part number 77 00 426 752.
The part numbers must correspond to the vehicle equipment .
The following table shows the serial numbers from which the 2
nd generation passenger air bag module
(B) has been fitted.
REPLACEMENT COMPATIBILITY
NOTE :
fitting of the 2nd generation passenger air bag modules (B) is in advance of the 2nd generation
computers (A) .
In this case these vehicles are fitted with an intermediary computer (A) (part number 77 00 434 205).

GENERAL
•The programmed restraint system (SRP) limits
the force of the belt on the body.
MAB11197S
All operations on the air bag and pretensioner
systems must be carried out by qualified and trai-
ned personnel.
These safety features are complementary.
In the event of a frontal impact of sufficient
force:
•the front seat belts retain the driver and pas-
senger.
•The pretensioners tighten the front seat belts
in such a way that they flatten them against the
body.•The air bag cushions inflate :
- from the centre of the steering wheel to pro-
tect the driver’s head,
- from the dashboard to protect the front pas-
senger’s head (according to equipment).

NOTE :
Vehicles fitted with front air bags are identified
by a sticker placed in the lower corners of the
windscreen on each side with the inscription "SRP
air bag" in the centre of the steering wheel and
on the dashboard (according to equipment).
Vehicles fitted with side air bags are identified by
a sticker placed in the lower corners of the winds-
creen on each side with the inscription"air bag"
on the side of the front seat backs (according to
equipment).
After each replacement of the windscreen, re-
member to apply the stickers mentioning that the
vehicle is fitted with air bags.
All of these stickers are available in a kit part num-
ber: 77 01 205 442.
15132R
In the event of a side impact of sufficient force,
the corresponding side air bag (on the impact
side) inflates on the door side, to protect the head
and thorax of the seat occupant.
IMPORTANT:
• Do not put covers on the front seats.
• Do not put anything in the way which will ob-
struct inflation of the air bags.
• In the event of work being carried out on the
vehicle sill (on the side impact sensor, on the
bodywork, on the seat belt inertia reel,...), the
air bag unit must be locked using the fault
finding tool.
• Any operation involving removal and refitting
of the seat trim on a seat back fitted with a
side air bag, must not be carried out for the
time being.
In case of a fault on the air bag cushion or follo-
wing its inflation, the whole seat must be repla-
ced following the specific Parts Department or-
der procedure .
Reminder : for vehicles fitted with self contained
side air bags, refer to Technical Note 3064A.
IMPORTANT : the pyrotechnic systems (pretensio-
ners, front and side air bags) must be checked
using a fault finding tool :
- following an accident in which the air bags
did not inflate,
- following a theft or attempted theft of the ve-
hicle,
- before selling a second hand vehicle.

SPECIAL TOOLING
These systems can have fault finding carried out
using the following fault finding tools :
•
XR25 only for pretensioners and front air
bags,
•
NXR or OPTIMA 5800 for pretensioners and
front and side air bags (except self contained
side air bags).
These tools allow faults in the computer or faulty
lines in the system to be detected (see the"Fault
Finding" section).
NOTE : These tools have an additional function
which allows the trigger lines to be deactivated,
to prevent triggering of the pyrotechnic gas gene-
rators.
XRBAG TEST KIT (Elé. 1288)
This equipment is a specially designed tool for
testing and fault finding of air bag and seat belt
pretensioner devices.
It allows electrical measurements to be made on
the various lines of the systems (see the "Fault
finding" section).
IMPORTANT : no measurements may be made on
these systems using an ohmmeter or any other
electrical measuring equipment: the system may
be triggered due to the operating current of the
measuring equipment.
14328S
This bornier is connected in place of the compu-
ter.
Using the
XRBAG, it allows all the trigger lines to
be checked, the computer supply voltage to be
measured and forces the air bag warning light on
the instrument panel to illuminate.
Terminals also allow continuity checks on the dia-
gnostic lines, on the warning light lines and on
the supply to the computer (see "Fault Finding"
section).

DUMMY IGNITION MODULE
A dummy ignition module integrated in a small
red box is supplied in the XRBAG.
It has the same electrical specifications as a real
ignition module and is used to replace the air bag
or the pretensioner during fault finding.
Refer to your After Sales Head Office for further
information.

DESTRUCTION EQUIPMENT
In order to avoid any risk of an accident the pyro-
technic gas generators for the air bags and seat
belt pretensioners must be triggered before the
vehicle or the part is scrapped.
Tool Elé. 1287 must be used which is provided for
this purpose.
96832R
Refer to "Destruction procedure" section.
IMPORTANT: do not trigger pretensioners which
must be returned under warranty for a stalk pro-
blem. This makes analysis of the component im-
possible for the supplier.
Return the component in the packaging of the
new one.
OPERATION OF PRETENSIONERS AND FRONT AIR
BAGS
When the ignition is switched on, the control war-
ning light for these systems is illuminated for se-
veral seconds and then is extinguished.
The computer is on standby and monitors the de-
celeration of the vehicle using the signal measu-
red by two integral decelerometers.
In the event of a frontal impact of sufficient force,
one of them simultaneously triggers the pyrote-
chnic generators for the two seat belt pretensio-
ners.
Under the force of the gas generated by the sys-
tem, a piston moves in its cylinder pulling a cable
connected to a corresponding central buckle
which retracts the seat belt (see the
"Pretensioners" section).
If the frontal impact is greater, the second elec-
tronic decelerometer triggers the ignition of the
pyrotechnic gas generators which inflate the dri-
ver and passenger air bags (according to equip-
ment).
These systems will not trigger in the event of:
- a side impact,
- a rear impact.
When triggered, a pyrotechnic gas generator pro-
duces an explosion and a small amount of smoke.
NOTE : the computer and ignition modules supply
normally comes from the vehicle battery.
However, an energy reserve is included in the
computer in case the battery is disconnected at
the start of the impact.
