Disconnect the battery.
Lift the rear bench seat (depending on
equipment).
Remove the pump and sender unit steel cover.
Disconnect the electrical connector (1).
Release the clips (2).
Then disconnect the fuel supply pipe (3) (green
marking on the quick-release union) and the fuel
return pipe (4) (red marking on the quick-release
union) using the special pliers Mot. 1265 or Mot.
1265-01.
IMPORTANT: When the pipes are removed, fuel
may be splashed out due to the residual pressure
in the pipes. Take appropriate precautions.
IMPORTANT :
During any operation on the fuel level sensor
you must observe the following precautions:
- Do not smoke.
- Keep all flames or incandescent objects away
from the working area.
REMOVAL OF THE PUMP - SENDER ASSEMBLY
The pump and sender unit assembly may be
removed through the inspection cover under the
rear bench seat and the fuel tank does not have to
be removed.

Tighten the mounting nut on the fuel and sender
unit assembly to a torque of 3.5 daN.m using the
tool Mot. 1264-01, holding the sender unit to pre-
vent it from rotating.
Make sure that the connector is firmly locked and
that the quick-release unions are securely clipped
on (with 2 O-ring seals)
Reconnect the battery.
CONNECTION
Disconnect the connector and the pipes on the
sender unit side.
Remove the mounting nut (5) of the pump and
sender unit using tool Mot. 1264-01.
Slacken the nut, remove the tool, unscrew the nut
by hand and remove it.
Remove the pump and sender unit assembly.
NOTE : If several hours may pass between
removing and refitting the pump and sender unit
assembly, refit the nut to the fuel tank to prevent
it from distorting.
REFITTING OF THE PUMP AND SENDER UNIT
ASSEMBLY
Special notes
Check that the seal is in good condition and re-
place it if necessary.
Fit the seal on the fuel tank first before fitting the
assembly.
Refit the pump and sender unit assembly in the
fuel tank by aligning it so that the indexing arrow
(F) is positioned in line with the longitudinal axis
of the vehicle, pointing towards the rear of the
vehicle.

INSTRUMENT PANEL
Oil level sensor

98898R1
OPERATION
The sensor consists of a wire with a high
coefficient of resistance. When a current passes
through the wire it does not have the same
thermal conductivity when it is immersed in a
liquid as when it is in the open air.
After a fixed time a voltage difference is obtained
at the sensor terminals depending on the depth of
immersion of the wire. This voltage difference is
recorded by the electronic unit which manages
the level display function and also controls the
"low oil level" warning light display on the
central liquid crystal display.
When the ignition is switched on, the central dis-
play shows the oil level in a series of "blocks" for
approximately 30 seconds, before returning to
displaying the trip mileometer and total mileome-
ter functions (or "odometer" function).
NOTE : Turning the trip mileometer reset button
before the end of the timed period will display
the "odometer" function.
LOOKING FOR FAULTS
If a short circuit or an open circuit is detected
when the oil level is measured, the display will im-
mediately show the trip mileometer / clock dis-
plays.
CHECKING
The sensor resistance must be between 6 and 20
ohms.
The sensor is deemed to be in short circuit for a va-
lue lower than 4 ohms.
The sensor is deemed to be in open circuit for a va-
lue higher than 22 ohms.

OPERATION
A thermistor transmits a variation in resistance to
a receiver, depending on the coolant
temperature, and a threshold overshoot switch
illuminates the warning light on the instrument
panel when the temperature reaches 118°C.
CHECKING
Connect an ohmmeter between track 1 (K and E
engines) or track 2 (F engine) on the sensor and
vehicle earth.
Correct value : 160 to 1 250 Ω.

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.
84
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).
12970R2
Move the stalk mounting assembly back slightly
and disconnect the connectors.

CONTROLS - SIGNALS
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).
84
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.

WIRING
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).
