Maintenance
In the event of a malfunction with the system, the "ECO OFF" switch warning lamp flashes, then comes on continuously. Have it checked by a CITROËN dealer or a qualified workshop.
Operating fault
This system requires a specific battery with a special specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop). Fitting a battery not listed by CITROËN introduces the risk of malfunction of the system.
Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of START mode.
The Stop & Start system makes use of advanced technology. All work on this type of battery must be done only 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. Depending on version, an alert message may also be displayed asking you to put the gear lever into position Nand put your foot on the brake pedal.
It is then necessary to switch off the ignition, then restart the engine using the key or the "START/STOP" button.
Reactivation
The system is reactivated automatically at every new start using the key or the "START/STOP" button.
Press the "ECO OFF" switch again. The system is active again; this is confirmed by the switch warning lamp going off and the display of a message.
Deactivation
At any time, press the "ECO OFF" switch to deactivate the system. This is confirmed by the switch warning lamp coming on accompanied by the display of a message.
If the system has been deactivated in STOP mode, the engine restarts immediately.
