Reactivation
Press the "ECO OFF" switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and a
message in the screen.
The system is reactivated automatically
at every new start using the START/
STOP button.
Operating fault
In the event of a fault 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.
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 place the gear
lever in position N and put your foot on the
brake pedal.
It is then necessary to switch off the ignition
and start the engine again using the "START/
STOP" button.
Maintenance
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from
automatic operation of START mode.
This system requires a 12 V battery with a
special specification and technology (reference
numbers available from CITROËN dealers).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the system.
For charging, use a 12 V charger and do not
reverse the polarity.
The Stop & Start system makes use of
advanced technology. For any work on
the system go to a qualified workshop
with the skills and equipment required,
which a CITROËN dealer is able to
provide.
