IMPORTANT : before removing the air bag cus-
hion, lock the computer using the fault finding
tool.
When this operation is activated, all the trigge-
ring lines are inhibited, the air bag warning light
on the instrument panel is illuminated
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 : When removing the steering wheel,
the air bag connector must be disconnected (D)
(see below).
The air bag is fitted with a connector which short
circuits when it is disconnected to avoid incorrect
triggering .
Remove the air bag cushion by its two torx bolts
located behind the steering wheel and disconnect
its connector (D).

IMPORTANT : before scrapping an untriggered air
bag module, it
MUST be destroyed in accordance
with the method described in the "Destruction
Procedure" section
Refitting
Reconnect the air bag cushion and mount 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 : 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.
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).

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.
