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.

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).

Special features after triggering
These types of unit (30 or 50 track) can accept up
to four triggerings maximum. Therefore it is not
necessary to replace them each time the air bags
or pretensioners are triggered .
In the event of being triggered, the warning light
on the instrument panel is illuminated, but the
computer does not lock the ignition lines which
have not been triggered. These remain in opera-
tion.
On the other hand, the computer locks the memo-
rised faults in order to prevent accidental erasing
of the context register for the impact which cau-
sed triggering.
These contexts can later be used to simplify the
repair of the vehicles involved in accidents and al-
so for examination needs.
IMPORTANT, during repair following an impact,
an unlocking command must be carried out follo-
wed by a locking command for the computer to
lock all of the ignition lines.
Erasing memorised faults is only possible follo-
wing a computer unlocking command.
If the fault finding tool does not recommend re-
placing the computer, only replace the triggered
components and check that there are no faults.
When everything is correct, unlock the computer
using a fault finding tool; the system is again ope-
rational.
If the fault finding tool recommends replacing the
computer, it will indicate either :
• that the computer has triggered four times ei-
ther just the pretensioners or the pretensio-
ners and air bags or the side air bag which is
not self contained (according to equipment),
• or an internal fault in the computer .
In these two circumstances, replace the computer.Special notes for replacing the computer
A new computer must be fitted to the vehicle be-
fore reconnecting its connector (tightening tor-
que : 0.8 daN.m).
The arrow on the computer must point towards
the front of the vehicle.
After connecting the connector, carry out a check
using the fault finding tool and proceed with
configuration if the vehicle does not have a pas-
senger air bag.
When everything is correct, unlock the computer
using a fault finding tool; the system is again ope-
rational.

OPERATION ON THE TRIGGERING LINES
In the event of a fault noted on one of these lines,
the component must be replaced and not repai-
red.
This safety device can not tolerate any conventio-
nal repair operation on the wiring or connectors.
The air bag and pretensioner triggering lines are
integrated in the passenger compartment wiring
harness. In order to make repairs easier, the re-
placement method consists of cutting the two ex-
tremities of the faulty wiring and making the
new wiring follow the same route along the pas-
senger compartment wiring harness.
IMPORTANT: when refitting the new wiring, en-
sure that it is not subject to damage and that the
original cleanliness has been respected.
Special case : the connector with lugs
A series of vehicles are fitted with a red connector
with lugs(A) passenger air bag module side.
16008R
To disconnect it, carefully use a small screwdriver
as a lever , so as not to damage the lugs .
In the event of the lugs breaking, replace the
connector using the kit part number : 77 01 206
210 using the following method.
