1) Ensure that the handbrake is up.
2) Put the gear lever into neutral.
3) Press the clutch pedal fully down, without pressing the accelerator.
4) Turn the ignition key to AVV and let it go the moment the engine starts.
If the engine does not start at the first attempt, return the ignition key to STOP before trying to start the engine again.
If the warning lights 
stay on when
the ignition key is at MAR, turn the key to STOP and then to MAR again; if the warning
light stays on, try with the other keys provided.
If you are still unable to start the engine, perform the emergency start-up procedure (see section “In an emergency”) and go to a Fiat Dealership.
IMPORTANT
Never leave the ignition key at MAR when the engine is off.
