FUEL CIRCUIT DISARMED
In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine.
The fl ashing of this warning
light is accompanied by a
message on the display.
When the tank’s minimum
level is reached, this warning
light comes on, accompanied
by the message "Fuel
level low" on the display.
You have enough fuel left to cover
approximately 30 miles (50 km) ,
depending on driving conditions and
the engine.
If the warning light fl ashes, this
indicates a fuel gauge malfunction.

If you should run out of fuel, it is
necessary to re-prime the circuit:
- fi ll the fuel tank with at least fi ve litres of diesel,
- squeeze and release the manual re-priming pump, under the bonnet
under the protective cover, until fuel
appears in the transparent pipe,
- operate the starter until the engine starts.
A label on the inside of the fl ap
indicates which type of fuel to use.
If you fi ll your tank, do not continue
after the third cut-off of the pump
nozzle. This could result in vehicle
malfunctions.
The capacity of the tank is
approximately 18 gallons (
80 litres).
