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.

Removal - Refitting
Any operation involving removal and refitting of
the seat trim of 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: 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).
On the other hand, in the event of a triggering
being caused, the side impact sensor must be re-
placed (certain components lose their nominal
specifications after the triggering energy has pas-
sed through them).
IMPORTANT :
• Before removing a seat, lock the computer
using the fault finding tool.
When this operation is activated, all the trig-
gering lines are inhibited and the air bag war-
ning light on the instrument panel is illumina-
ted.
• When refitting, after replacing the seat and
reconnecting the connectors, carry out a check
using the fault finding tool. Unlock the
computer if everything is correct, otherwise
see the"Fault Finding" section.
IMPORTANT : before scrapping an untriggered air
bag module, it
MUST be destroyed in accordance
with the method described in the "Destruction
Procedure" section
