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.

After deactivating the air bag function using the
fault finding tool and removing the passenger air
bag module :
• cut the passenger air bag wiring 60 mm from
the instrument panel wiring tape,
• unsheath the passenger air bag supply wiring
by 30 mm,
• strip the wiring provided in the kit and the
passenger air bag wiring by approximately10
mm,
• thread 2 cm of heat shrink sleeving (provided
in the kit) on each of the vehicle’s wiring lines,
• solder the vehicle’s wiring to the wiring in the
kit (B),
• position the heat shrink sleeving over the sol-
dered joins and heat it,

• refit and secure the passenger air bag module,
• connect the new connector to the passenger
air bag module,
• carry out a check using the fault finding tool.
Unlock the computer if everything is correct,
otherwise see the "Fault Finding " section.

Refitting
IMPORTANT: the safety notes which must be fol-
lowed to refit or replace the passenger air bag
module must be observed .
If these procedures are not correctly observed the
systems may not operate correctly or may be acci-
dentally triggered, presenting a danger to the oc-
cupants of the vehicle.
Refitting is the opposite of removal
IMPORTANT: a 2nd generation passenger air bag
module must not be fitted to a vehicle fitted with
a 1
stgeneration computer (see the table on
pages 2 and 3).
Observe part numbers mentioned in the spare
parts catalogue, referring to vehicle equipment.
REMINDER: the computer in these vehicles can wi-
thstand several triggerings. Therefore, it does not
have to be replaced after every triggering of the
air bag(s) or pretensioners (see "Computer" sec-
tion).
IMPORTANT
• No foreign body (bolt,clip...) must be forgotten
when refitting the air bag module.
• Reconnect the passenger air bag module and
secure it (tightening torque : 0.6 daN.m).
• Press the connector in firmly on the module
side (strong clipping system).
• Attach a blue adhesive sticker " after sales sys-
tem tamperproof label" sold under part num-
ber : 77 01 205 356 on the air bag module
connector.
• After refitting everything, carry out a check
using the fault finding tool.
• Unlock the computer if everything is correct,
otherwise see the"Fault Finding" section.
SIDE AIR BAG MODULE
Description
It is fitted into the seatback of the front seats on
the door side.
It comprises :
- an inflatable bag,
- a pyrotechnic gas generator and ignition
module.
These components cannot be separated.
15132R
In order to work the inflatable bag tears through
the module cover, the foam and the seat trim.
NOTE: this system is operational after the ignition
has been switched on.
IMPORTANT:
The pyrotechnic systems (pretensioners 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.
No measurements may be made on these systems
using an ohmmeter or any other electrical measu-
ring equipment: the system may be triggered due
to the operating current of the measuring equip-
ment.
