Operating fault
In the event of a fault with the
system, this warning lamp 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
selector 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.
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from
automatic operation of START mode.

Maintenance

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.
