Remote control for door locking
88
.GENERAL
These vehicles are equipped with an infrared or
radio frequency remote control with rolling code,
which prevents the code from being copied.
When a transmitter is replaced it will therefore be
necessary to resynchronise it so that the transmit-
ters are returned to phase with the decoder unit.
This remote control is only used for locking and
unlocking the opening elements (it has no effect
on the immobiliser).
IMPORTANT: this system cannot operate with
three remote controls (the decoder unit can only
manage two different rolling codes).
THE TRANSMITTER (PLIP)
Replacing or adding a remote control with immo-
biliser function without replacing the decoder
unit.
Order a spare key head using the number in the
head of one of the old keys or the label normally
attached to the keys when the vehicle is delivered
(eight alphanumeric characters).
If a key is being added or has been lost, remember
to order the insert with the key number.
Carry out the special resynchronisation procedure
using the XR25.
This procedure resets the remote control into se-
quence with the decoder unit (rolling code) and
should only be used if the decoder unit is not
being replaced (with immobiliser only).
1.Ignition off, connect the XR25 (ISO selector on
S8, code D56).
For vehicles fitted with an infra-red remote
control, enter command mode G04* (forced
protection mode) then switch the ignition on
again and enter the vehicle’s security code
(see procedure in section 82).
For vehicles fitted with a radio frequency re-
mote control, go to point 2.
2.Switch the ignition off and enter command
mode G32*.
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
and bargraph 17 LH on the XR25
(code D56,
fiche n° 56).
3.Press the remote control twice (the doors lock
and unlock and the red warning light extin-
guishes).
NOTE :
- When replacing a key head, resynchronisa-
tion of the second remote control (if fitted)
is not always necessary.
Check that the second control operates,
otherwise resynchronise it.
- If both remote controls (if fitted) are desyn-
chronised, 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).
4.The procedure is complete - check that the
doors lock correctly.

Replacing or adding a remote control without im-
mobiliser function without replacing the decoder
unit.
If the vehicle does not have an immobiliser, the re-
mote control does not have a special number. A
key head without a number may therefore be or-
dered.
If a key is being added or has been lost, remember
to order the insert with the key number.

4.The procedure is complete - check that the

Simple resynchronisation procedure
This procedure allows the remote controls to be
reset with the decoder unit (rolling code).
This procedure is used:
- when the remote control code no longer lies
within the reception range of the decoder unit
(over 1,000 consecutive presses on the remote
control, away from the vehicle).
- when replacing a decoder unit alone (new de-
coder unit),
- when replacing a remote control if the decoder
unit is new (replacing a kit).
REMINDER: when replacing or adding a remote
control with immobiliser function without repla-
cing the decoder unit, refer to "Replacing or ad-
ding a remote control with or without immobili-
ser function without replacing the decoder unit"
(specific resynchronisation procedure).

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).

REMOTE CONTROL RECEIVER
This is located near to the courtesy light.
It receives the remote control code and transmits
it to the decoder unit. Its function is to amplify the
signal.
The remote control receiver is replaced indepen-
dently of the transmitter and the decoder unit (it
is not coded).
Removal - Refitting
Remove:
- the light diffuser, lifting it with a small screw-
driver at points (A),

Replacement
For vehicles fitted with an immobiliser, refer to
section 82 (programming procedure). The decoder
unit is common to the immobiliser.
For vehicles without an immobiliser, carry out a
resynchronisation operation.
NOTE : Fault finding for the remote control sys-
tem may be carried out using the XR25 (fault fin-
ding fiche n° 56).
Move the dashboard as far back as possible, dis-
connect the decoder unit and remove the two
mounting bolts (B) using a small ratchet fitted
with a Torx 20 socket.

Airbags and seat belt pretensioners
GENERAL

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.

3) FRONTAL IMPACT AGAINST A FLEXIBLE
OBSTACLE
The airbag trigger speed depends in this case on
the degree of flexibility of the bodywork of the
vehicle hit.
The more flexible the other vehicle, the higher the
trigger speed (for vehicles of equal flexibility and
100 % contact, the speed is higher than 40 km/h)
(relative speed).
4) OFFSET IMPACT AGAINST A FLEXIBLE
OBSTACLE
Here the airbag trigger speed depends on the an-
gle of impact α and the flexibility of the vehicle hit
in the direction of travel.
The vehicle speed for airbag triggering is greater
when the angle of impact α is greater and the
flexibility of the vehicle hit is high.
5) SUMMARY AND CONCLUSION
- The airbag only reacts to deceleration in the direction of driving. A side impact or the vehicle rolling over
cannot trigger the airbag.
- The vehicle’s projectile energy is transformed into deformation energy of the front part of the vehicle.
Deceleration is greater when the deformation of the vehicle hit is less, meaning that the airbag will trigger
much earlier.
- The minimum speed at which the airbag is triggered is greater when the angle of impact α is large (see
above).
- If, in a frontal impact, there is no deformation at the front pillars, or engine - gearbox - sub-frame impact,
the fact that the airbag was not triggered cannot be considered as a fault since the trigger speed may not
have been reached.
- The pretensioners always trigger at a lower speed than the airbag.
- Experience has shown that the impact speeds given by customers are often not correct. Their reactions are
generally reduced by shock: there is almost always confusion between the cruising speed before the im-
pact and the actual speed of the impact which is thankfully much lower in most cases.
