Fitting the "space-saver"
spare wheel
If your vehicle is fitted with alloy wheels,
when tightening the bolts on fitting, it
is normal to notice that the washers
do not come into contact with the
"space-saver" spare wheel. The wheel
is secured by the conical surface of
each bolt.
After changing a wheel
To correctly store the punctured wheel
in the boot (not in the location for the
space-saver wheel), first remove the
central cover.
When using the "space-saver" type
spare wheel, do not exceed 50 mph
(80 km/h).
Have the tightening of the bolts and the
pressure of the spare wheel checked
by a CITROËN dealer or a qualified
workshop without delay.
Have the punctured wheel repaired
and refitted to the vehicle as soon as
possible.
The tyre inflation pressures are given on this
label.
