In the event of a breakdown
Changing a bulb
With a 'space-saver' type spare wheel
The headlamps have polycarbonate
lenses with a protective coating:
F do not clean them using a dry or
abrasive cloth, nor with a detergent
or solvent product,
F use a sponge and soapy water or a pH
neutral product,
The following is recommended:
F when 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.
-
deactivate certain driving aid functions
(Active Safety Brake, Adaptive cruise
control, etc.), as indicated on the label
attached to the wheel,
do not exceed the maximum
authorised speed of 50 mph (80 km/h).
F Tighten the security bolt using the
wheelbrace 5 fitted with security socket 2.
F Tighten the other bolts using wheelbrace
5 only.
F Refit the bolt covers to each of the bolts
(depending on equipment).
-
F Store the tools.
Driving with more than one 'space-saver'
type spare wheel is prohibited.
Changing a bulb must only be done with
the ignition off and after the lamp has
been switched off for several minutes –
Risk of serious burns!
F Do 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.
After changing a wheel
Store the punctured wheel in the boot or,
depending on version, remove the central cover
first to store it beneath the floor in place of the
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.
