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.

F

Tighten the security bolt using the

wheelbrace 1

fitted with the security

socket 5 (depending on equipment).

F

Tighten the other bolts using the

wheelbrace 1

only.

F

Refit the wheel bolt cover(s) (depending on

equipment).

F

Stow the tools in the box.

The tyre inflation pressures are given on this
label.

D5S xenon bulbs must be changed
by a CITROËN dealer or a qualified
workshop, as there is a risk of
electrocution.
In the event of failure of one of
the D5S bulbs, it is recommended that
the bulb on the other side be changed
at the same time.

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,

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.

Changing a bulb should only be done
after the headlamp 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 imperative to use only anti-
ultraviolet (UV) type bulbs to avoid
damaging the headlamp.
Always replace a failed bulb with a
new bulb with the same type and
specification.
