Front left seat moved back fully.
Slide the front left-hand seat back as far as
possible.
Raise the pre-cut zone B in the carpet
under the seat.
Pierce the protective cover C on the tube D
with the release device (located in the
boot).
Place the release device in the tube D.
Turn the release device clockwise making
several dozen turns
For safety reasons , it is essential to
continue turning the device as far as it will go.
The parking brake is released.
Remove the release device and stow it.
The operation of the parking brake
reinitialises after the ignition is switched off
then on again. If the reinitialisation of the
parking brake proves impossible, contact a
CITROËN dealer or a qualified workshop.
The (subsequent) time required for
application may be longer than during
normal operation.
For safety reasons, you must contact a
CITROËN dealer as soon as possible to
replace the protective cover.
Take care not to allow moisture or dust
in the proximity of the protective cover.
Following an emergency unlocking,
immobilisation of the vehicle is no
longer guaranteed once the manual
emergency release has been deployed
and the manual control does not allow
the re-application of your parking brake.
Take no action, either on the control
lever A, or stopping or starting the
engine while the release device is
engaged.
To re-engage the electric parking brake
(after correction of the fault or battery
problem), make a long pull on the
control lever A until the parking brake
warning lamp in the instrument panel
flashes then make a second long pull
until this warning lamp comes on fixed.
