When using the "space-saver" spare
wheel, do not exceed a speed of
50 mph (80 km/h).

pressure of the spare wheel checked
by a CITROËN dealer or a qualified
workshop without delay.

Fitting snow tyres
If you equip your vehicle with snow
tyres fitted on steel wheel rims, special
bolts available from your CITROËN
dealer or a qualified workshop must
be used.
If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.
