REMOVAL - REFITTING
Disconnect the battery and set the wheels
straight.
Remove the steering wheel and the two half cow-
lings (for vehicles with an airbag, refer to the re-
moval of the rotary switch on the following page
or section 88 for special notes on removing the
steering wheel).
Special notes for vehicles with an airbag
Before removing the assembly, the position of the
rotary switch under the steering wheel must be
noted:
- by ensuring that the wheels are straight on re-
moval so that the strip may be positioned in the
centre,
- by immobilising the rotary switch rotor using
adhesive tape.
Slacken the bolt (C) then sharply tap the screwdri-
ver to release the cone.

Special notes for refitting
Fit the mounting with its components, connect
the various connectors and push the assembly
back against the steering column.
Continue refitting and do not lock bolt (C) until
the two half cowlings are refitted, so that the
stalks may be aligned with the dashboard and the
instrument panel.
This operation is made easier by a cut-out section
giving access to bolt (C) in the lower half cowling.
For vehicles with an airbag, observe the re-
commendations in the section " Special notes for
the rotary switch under the steering wheel" on
the following page or section 88 (driver’s airbag).

- the horn connector, if fitted,
- the steering wheel bolt,
- the steering wheel after setting the wheels
straight,
- the half cowlings (3 bolts).
Disconnect the connector for the rotary switch
and remove it after removing the three mounting
bolts (E).
Before removing the rotary switch its position
must be noted:
- by ensuring that the wheels are straight on re-
moval so that the track may be positioned in
the centre,
- by immobilising the rotary switch rotor using
adhesive tape.
If it is being replaced, the new part is supplied rea-
dy centred by an adhesive label which will tear off
as soon as the steering wheel is turned for the first
time (fit with the wheels straight).

Disconnect the battery.
Remove:
- the airbag cushion by the two torx T30 bolts
(tightening torque : 0.5 daN.m) located behind
the steering wheel and disconnect the connec-
tor (D),
IMPORTANT: It is not permitted to operate the
pyrotechnical systems (airbags and pretensioners)
near a source of heat or flame as there is a risk of
triggering.
IMPORTANT : If the steering wheel is removed,
the airbag connector (D)
MUST be disconnected.
The airbag has a connector which short circuits if
it is disconnected to prevent incorrect triggering.

Rotary switch under steering wheel
Special notes for refitting
Ensure the wheels are still straight.
Ensure the rotary switch under the steering wheel
is still immobilised before refitting.
If there is any doubt follow the method for cen-
tring described in section 88 "driver’s airbag".
Renew the steering wheel bolt each time it is re-
moved (pre-bonded bolt).
Observe the correct tightening torque (4.5
daN.m).

IMPORTANT
Before reconnecting the driver’s airbag cushion,
check to see if the system is operating correctly as
follows:
•check the airbag warning light on the
instrument panel is illuminated when the
ignition is on,
•connect a dummy ignition module to the
driver’s airbag connector and check that the
warning light extinguishes,
•switch the ignition off, connect the airbag
cushion in place of the dummy ignition module
and secure the cushion to the steering wheel,
•switch the ignition on. Check the warning light
illuminates for three seconds when the ignition
is switched on then extinguishes and remains
extinguished.
If the warning light does not operate exactly as
described above, refer to the fault finding section
and test the system using the XRBAG (Elé. 1288)
(see section 88).
IMPORTANT: if these instructions are not obser-
ved, the systems may not operate normally and
may be incorrectly triggered.

Remote control for door locking
88
Ignition off:
1.Press and hold the central door locking button
for a few seconds until the doors lock and un-
lock.
From this moment, the operator has 10 se-
conds to carry out the next operation.
NOTE: The 10 seconds are shown by the illu-
mination of the red immobiliser warning light
(if fitted) and bargraph 17 LH on the XR25
(code
D56, fiche n° 56).
2.Press the remote control twice (the doors lock
and unlock and the red warning light extin-
guishes, if fitted).
NOTE : If both remote controls (if fitted) are
desynchronised, two resynchronisation proce-
dures will have to be carried out (one for each
remote control).
IMPORTANT: To ensure that the infrared code
is correctly transmitted it is essential to direct
the transmitter correctly towards the receiver.
If the procedure fails it will be necessary to
restart from the beginning (infrared remote
control only).
3.The procedure is complete - check that the
doors lock correctly.
Removal - Refitting
The dashboard must be partially removed to re-
move the decoder unit.
Remove:
- the steering wheel with the wheels straight,
- the half cowlings under the steering wheel,
- the knee protector under the steering column,
- the lights and wiper controls,
- the instrument panel surround,
- the instrument panel,
- the ashtray, its mounting and the two dash-
board mounting bolts on the heating unit,
- the trim at the bottom of the dashboard on the
driver’s side,
- the two speaker grilles on the dashboard,
- the dashboard mountings.
THE DECODER UNIT
The decoder unit is located in the left hand side of
the dashboard (A).

IMPORTANT : all work on the airbag and
pretensioner systems must be carried out by
qualified personnel who have received the proper
training.
There are 3 safety systems which supplement the
seat belt.
If a frontal impact is sufficiently strong, the elec-
tronic unit controlling these systems triggers:
•The pretensioners which restrict the seat belts
for the front seats so that they are pressed
against the body.
•The airbag cushion which inflates from the
centre of the steering wheel to protect the
driver’s head.
•The airbag module which inflates from the
dashboard to protect the front passenger’s
head.

FUNCTION AND OPERATION OF THE AIRBAGS AND PRETENSIONERS
1) Function
In the event of an accident, the airbag prevents the head striking the steering wheel or dashboard.
It also reduces the maximum acceleration of the head, by absorption.
2) Trigger threshold
Generally speaking, there are four different basic situations.
1) FRONTAL IMPACT AGAINST A OBSTACLE
The trigger speed depends on the obstacle’s
surface. The softer the surface, the higher the
speed.
The pretensioner generally triggers at a lower
speed than the airbag.
2) OFFSET IMPACT AGAINST A OBSTACLE
In this case, the airbag trigger speed depends on
the angle of impact α.
The greater the angle, the higher the vehicle
speed for triggering.

The new 30-track computers are provided with
the K and L lines for fault finding with the XR25
(except for vehicles with pretensioners only).
This enables computer faults or faulty lines to be
detected in the system (see section on fault fin-
ding).
NOTE: before each operation an auxiliary func-
tion enables the ignition lines to be de-activated
to prevent the risk of triggering the pyrotechnic
gas generators.
Various vehicle configurations are possible:
Vehicle fitted with:
- pretensioners only,
- pretensioners and driver’s airbag,
- pretensioners and driver’s airbag and passen-
ger’s airbag.
NOTE :
• A vehicle fitted with a driver’s airbag will be
identified by a label in the bottom corner of
the windscreen on the driver’s side, and by the
word "Airbag" in the centre of the steering
wheel.
• If a passenger airbag is fitted, a second label is
located in the lower corner of the windscreen
on the passenger side and the word "Airbag" is
located on the dashboard on the same side.
Each time the windscreen is replaced, remember
to fit the labels showing that the vehicle is fitted
with airbags.
These labels are available in a kit Part Number :
77 01 205 442.
