CITROEN C3 AIRCROSS Handbook page 56

In the event of a breakdown
► Extend jack 1 with the jack handle 2 and
wheel wrench 3 until its head comes into
contact with jacking point A or B; contact
area A or B on the vehicle must be properly
inserted into the central part of the head of the
jack.
► Raise the vehicle until there is sufficient
space between the wheel and the ground to
admit the spare (not punctured) wheel easily.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack
may slip or collapse - risk of injury!
Take care to position the jack strictly at
one of the jacking points A or B under the
vehicle, ensuring that the head of the jack
is centred under the contact area of the
vehicle. Otherwise, there is a risk of damage
to the vehicle and/or of the jack collapsing -
risk of injury!
