Emergency unlocking
For safety reasons, after this manoeuvre it is essential to contact a CITROËN dealer urgently to have the plug
replaced.
Following an emergency unlocking, immobilisation of the vehicle is no longer guaranteed once the manual emer-
gency unlocking has been deployed and the manual control does not allow the re-application of your parking
brake.
Take no action, either on control A , or stopping starting the engine while the unlocking tool F is engaged.
Take care not to allow moisture or dust in the proximity of the plug.
