CITROEN DS3 Owner's Handbook Manual page 156

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.
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.
Remove the bolts and store them in a clean
place.
Remove the wheel.
