Oil pressure warning light
When the ignition is switched on, the oil pressure warning light illuminates.
When the engine is running and the oil pressure is sufficient, the warning light goes out.
The oil pressure signal is transmitted to the instrument panel by a wire connection.
The signal is produced by the oil pressure switch.

Total mileage
The total mileage is displayed as soon as the ignition is switched on.
Press the Trip computer scroll button or the Reset button to move to the next page.
Trip mileage
The trip mileage is displayed instead of the total mileage when the Trip computer or the Reset button is pressed
briefly.
Except in the following cases:
– it is reset by a long press of the instrument panel Reset button,
– resetting the trip mileage is different from resetting the trip computer (distance travelled).
Trip computer
The various sequences of the trip computer can be displayed instead of the mileage by pressing the button at the
end of the wiper stalk (Trip computer button). It is reset by a long press of the Reset button.
The signals from the trip computer are displayed after the trip mileage as follows:
–Fuel consumed (in litres per 100 km) since the last reset,
–Average consumption (in litres per 100 km) since the last reset.
This is only displayed after the vehicle has travelled 400 m.
This takes into consideration the distance covered and the fuel consumption since the last time the reset button was
pressed.

Estimated range with remaining fuel (in km).
This is only displayed after the vehicle has travelled approximately 400 m. This is the potential distance remaining
calculated on the basis of distance travelled, amount of fuel remaining in the tank and fuel consumption.
Note :
The range is no longer displayed 3 minutes after the low fuel level warning light illuminates.
–Distance travelled since the last reset.
–Average speed since the last reset.
This is displayed after the vehicle has travelled 400 m. It is obtained by dividing the distance travelled by the time
elapsed since the last reset. The time base is internal to the on-board computer.
