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 both cases, if automatic operation of the
electric parking brake has been deactivated,
you must apply the parking brake by pulling
the control lever.
When immobilising the vehicle, with
the engine running, you must place the
selector lever in neutral N.
Before carrying out any work in the
engine compartment, ensure that the
selector lever is in neutral N and that
the parking brake is applied.
Whatever the circumstances, you must
manually apply the parking brake when
parking, if automatic operation has
been deactivated.
In the event of a battery failure, use the
chock to immobilise the vehicle.
Operating fault
With the ignition on, the flashing of A or
AUTO, accompanied by an audible signal and
a message, indicates a malfunction of the
gearbox.
Have it checked by a CITROËN dealer or a
qualified workshop.
