Priming the fuel system In the event of running out of fuel:
A 1.9 D ENGINE: - After filling (5 litres minimum), operate the manual priming pump untilsome resistance is felt.
- Operate the starter motor while depressing the accelerator pedal slightly until the engine starts.
If the engine fails to start at the first attempt, wait 15 seconds before trying again. If the engine fails to start after several attempts, repeat the procedure from the beginning. When the engine is idling, accelerate slightly to complete the bleeding of the circuit. Engine 2.0 HDi: After adding fuel, turn the ignition key to position M, then operate the star-
ter motor until the engine starts. Injection pump Do not remove the seals on the pump setting screws under any circum- stances. Alteration of the settings might lead to early engine failure and loss of war-
ranty cover.
B Draining water from the fuel filter Bleed regularly (each time the engine is drained).
To remove the water, loosen the bleed screw at the bottom of the filter.Operate until all the water has been expelled.
