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.

Refitting
Ensure that the wheels are still straight.
Check that the mark "0" on the rotary switch is
correctly positioned opposite the fixed index (E).
IMPORTANT: If these procedures are not correctly
observed the systems may not operate correctly
or may be accidentally triggered.
Engage the assembly on the steering column and
connect the different connectors.
Carry out the rest of the refitting and only lock
bolt (C) once the two half cowlings have been re-
fitted, to position the stalks in alignment with the
instrument panel and the dashboard.
This operation is made easier by a cut-out giving
access to the bolt (C) in the lower half cowling.
Change the steering wheel bolt after each remo-
val (pre-bonded bolt) and observe its tightening
torque (4.5 daN.m).
Reconnect the air bag cushion and fix it to the
steering wheel (tightening torque : 0.5 daN.m).
NOTE : press the connector in firmly on the cus-
hion side(D) (strong clipping system).
IMPORTANT
• To avoid damaging the rotary switch under the
steering wheel, the fixed position of the stee-
ring wheel must be maintained during the ope-
ration.
• If there is any doubt about whether the stee-
ring wheel is correctly centred, it must be remo-
ved for verification.
• In the event of an operation to remove the
steering, engine, transmission components etc,
where the steering rack and steering column
have to be separated, the steering wheel must
be immobilised using a "steering wheel
locking" tool.
IMPORTANT : after refitting every thing, carry out
a check using the fault finding tool.
Unlock the computer if everything is correct,
otherwise see the"Fault Finding" section.
PASSENGER AIR BAG MODULE
Description
It is mounted in the dashboard opposite the front
passenger.

It consists of:
- an inflatable cushion,
- a pyrotechnic gas generator and ignition mo-
dule.
98124S
The air bag module components cannot be sepa-
rated.
NOTE : this system is operational when the igni-
tion has been switched on.
Accessing the ignition module
To access the ignition module of the passenger air
bag module, the upper part of the dashboard
must be removed.
Important, if the vehicle is fitted with a red
connector with lugs, see the recommendations on
the following page.
REMINDER: the ignition module check for the mo-
dule must be carried out using the
XRBAG as des-
cribed in the "Fault Finding" section.Removal
IMPORTANT:The pyrotechnic systems (pretensio-
ners or air bags) must not be handled when near a
heat source or a flame because there is a risk that
the system will be triggered.
IMPORTANT : Before removing a passenger air
bag module, lock the computer using the fault
finding tool.
When this operation is activated, all of the trigge-
ring lines are inhibited, the air bag warning light
on the instrument panel is illuminated.
To remove the passenger air bag module the up-
per part of the dashboard must be removed.
Remove:
- the windscreen pillar trim sections,
- the half cowlings under the steering wheel
- the mounting bolts on the upper part of the
dashboard and release it (for more details see
"section 83 in MR 337").
Disconnect the ignition module.
The passenger air bag module is mounted by six
bolts.
14092R1
IMPORTANT : In the event that the passenger air
bag module should be triggered, the deforma-
tion of the mountings (microcracks) means the
metal dashboard support beam must be replaced.

Reconnect the computer and the passenger air bag ignition module, then switch
on the ignition. Erase the computer memory then switch off the ignition.Carry out
a check using the fault finding tool and, in the absence of a fault, unlock the
computer.Destroy the passenger air bag module if there has been a replacement
(tool Elé. 1287).

Lock the computer using the command on the fault finding tool.
Switch off the ignition, disconnect the computer connector and fit the 30 track B40 adaptor.
The XRBAG must be used to measure resistance on adaptor cable B .
Is the value obtained correct?
If the value obtained is correct at adaptor cable B, check on the air bag computer base
for the 5 shunt opening pins for the 30 track connector.
Check the condition of the computer connections.
Check the condition of the 30 track connector (locking system, connections, ...)YES
If the value obtained is not correct at adaptor cable B , check the connections on the
30 track connector (tracks 13 and 14).NO
If the value remains incorrect, switch off the ignition and remove the dashboard visor
to access the passenger air bag module wiring. Disconnect the passenger air bag
ignition module, connect a dummy ignition module to the ignition module connector,
then use the XRBAG to measure the resistance on adaptor cable B again.
If the value obtained is correct, change the passenger air bag module.
If the value obtained is still incorrect, replace the air bag wiring.
