Operating fault
In the event of a fault with the system, the
button in the "EcO OFF" switch flashes for a
few moments, then remains on.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall.
All of the instrument panel warning lamps
come on.
It is then necessary to switch off the ignition
and start the engine again using the "START/
STOP" button.
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work on this type of battery must be
carried out only by a CITROËN dealer
or a qualified workshop.
For more information on the 12 V
battery, refer to the corresponding
section.
