-If the code is correct
is displayed.
Bargraph 10 LH extinguishes.
The engine may be started.
The vehicle is protected once more :
• approximately 10 minutes after switching
the ignition off (automatically),
• after disconnecting the battery.
-If the code is incorrect
is displayed.
Bargraph 10 LH remains illuminated.
The engine may not be started.
The red immobiliser warning light and the in-
jection warning light (depending on version)
flash.
Switch the ignition off, then repeat the proce-
dure for entering the code.
IMPORTANT: you may make 3 attempts to enter
the code. If, after the third attempt, the code is in-
valid, you must wait for approximately 15 mi-
nutes before making another attempt.
When this period has expired, switch the ignition
off and on again and 3 more attempts may be
made.
NOTE : This procedure does not decode the injec-
tion computer or coded solenoid valve (depen-
ding on the type of engine)- it only authorises the
starting of the vehicle.
REMINDER : The ignition must be switched off
and on again between attempts to enter the
code.

PROCEDURE FOR ENTERING THE SECURITY CODE
With this immobiliser system, the procedure for
entering the security code is managed by the de-
coder unit.
The code is entered using the XR25 only.
The security code can only be entered if the en-
gine immobiliser system is active. The red immobi-
liser warning light must flash when the ignition is
switched on (rapid flashing).
After determining the security code number (re-
quest from the local assistance network, example
DELTA Assistance for France, NVSR for the UK by
fax only) , carry out the following operations:
1.Ignition off, the red engine immobiliser war-
ning light should flash (slow flashing).
2.Switch the ignition on, the injection warning
light (petrol vehicle) illuminates for approxi-
mately 3 seconds then extinguishes, while the
red immobiliser warning light should flash
more quickly.
3.Connect the XR25 to the vehicle and set the
ISO selector on S8.
Enter code
Bargraph 10 LH should be illuminated (fault
finding fiche n° 56).

- coolant temperature gauge,

1 Trip mileometer reset button and clock reset (rotate).
NOTE :
• Under normal operating conditions, the oil level is only measured if the ignition has been switched off for
over one minute; otherwise the old oil level value is re-displayed.
If a fault is detected, however, an oil level measurement is made each time the ignition is switched on to
check if the fault is persisting.
• It is normal to find that the oil level is not always the same:
- parking on a slope,
- too short a wait after running the engine for a short moment (especially when the oil is cold), ...

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.

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.

IMPORTANT :
When everything has been refitted:
• Carry out a check using the XR25 to ensure that
there is no fault in the system.
• Unlock the computer with command G81* .
• Check that the airbag warning light illuminates
for 3 seconds after the ignition is switched on
then extinguishes and remains extinguished.
If the warning light does not operate as described
above, refer to the "Fault finding" section and
check the system using the XRBAG (Elé. 1288) or
XR25.
IMPORTANT:
If these procedures are not correctly observed the
systems may not operate correctly or may be
accidentally triggered.

- again rotate the part in the clockwise direction
by making two complete turns, and after this
operation make sure that the rotary switch is
actually in the position previously described.
Refit the steering wheel and replace the pre-
bonded bolt, ensuring its correct tightening tor-
que (4.5 daN.m).
Reconnect the airbag cushion and secure it to the
steering wheel, tightening torque (0.5 daNm).
SPECIAL CASES
Where work is being done involving removal of
the steering, engine, transmission, etc., requiring
uncoupling of the rack and steering column:
→ the steering wheel must be immobilised using a
"steering wheel locking" tool.
IMPORTANT: to avoid destroying the rotary
switch under the steering wheel it is IMPORTANT
to maintain the fixed position of the steering
wheel throughout the operation.
If there is any doubt about its correct centring the
steering wheel must be removed so that the cen-
tring method described above can be applied.
REMINDER: in this case, only qualified personnel
who have received the correct training must work
on the airbag.
