jacking Citroen DS3 DAG 2009.5 1.G Owner's Manual

 Place the jack 2 in contact with one of the two front A or rear B locations provided on the underbody, whichever is closest to the wheel to be changed. On vehicles fitted with sill finshers, the jacking location is indicated by a marking on the finisher. The jack must be placed centrally in line with this marking, at the jacking point located behind the finisher and not on the plastic finisher itself.
 Remove the bolts and store them in a clean place.  Remove the wheel.
 Extend the jack 2 until its base plate is in contact with the ground. Ensure that the centreline of the jack base plate is directly below the location A or B used.  Raise the vehicle until there is sufficient space between the wheel and the ground so that the spare (not punctured) wheel can then be fitted without difficulty.
