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 contact of each bolt.
After changing a  wheel
With a "space-saver " type spare wheel
Visit a   CITROËN dealer or a   qualified 
workshop as soon as possible to have the 
tightness of the bolts and the pressure of 
the spare wheel checked.
Have the punctured tyre examined. After 
inspection, the technician will advise you 
on whether the tyre can be repaired or if it 
must be replaced. The tyre inflation pressures are given on 
this label.

Changing a bulb
The lamps have polycarbonate lenses with 
a 
protective coating:
F
 
d
 o not clean them using a   dr y or 
abrasive cloth, nor with a
  detergent 
or solvent product,
F
 
u
 se a   sponge and soapy water or a   pH 
neutral product,
F
 
w
 hen using a   high pressure washer 
on persistent marks, do not keep the 
lance directed towards the lamps or 
their edges for too long, so as not to 
damage their protective coating and 
seals.
Changing a
  bulb should only be done after 
the lamp has been switched off for several 
minutes (risk of serious burns).
F
 
D
 o not touch the bulb directly with your 
fingers, use a
  lint-free cloth.
It is essential only to use anti-ultraviolet 
(UV) type bulbs, so as not to damage the 
headlamp.
Always replace a
  failed bulb with a   new 
bulb with the same type and specification. In some weather conditions (e.g. low 
temperature or humidity), the presence 
of misting on the internal sur face of the 
glass of the headlamps and rear lamps is 
normal; it disappears after the lamps have 
been on for a
  few minutes.
