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), ...

Oil level sensor

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.
