Door unlocking in the event
of a crash
In the event of a crash that triggers the fuel
cut-off switch, the doors will unlock automatically
to enable getting into the car
and at the same time the passenger’s compartment
lights will turn on. It is however
always possible to open the doors from
the passenger’s compartment by means of
the internal door handles.
If no fuel leaks are detected after the impact
and the car is ready to go, restore
correct operation following the instructions
given below.
To reset car operation, follow this procedure:
turn the ignition key to MAR;
activate the right-hand indicator;
deactivate the right-hand indicator;
