Driving
Stopping the vehicle
Before switching off the engine, you can:
- move to position N to engage neutral,
or
- leave the gear engaged; in this case, it will
not be possible to move the vehicle.
In all cases when parking, you must
apply the parking brake to immobilise
the vehicle.
When immobilising the vehicle, with
the engine running, you must place the
gear selector in neutral N.
Before carrying out any work in the
engine compartment, ensure that the
gear selector is in neutral N and that the
parking brake is applied.

Operating fault
With the ignition on, the flashing of AUTO,
accompanied by an audible signal and a
message in the screen, indicates a malfunction
of the gearbox.
Have it checked by a CITROËN dealer or a
qualified workshop.
