Changing a fuse

All work must be carried out only by a

CITROËN dealer or a qualiﬁed workshop

The replacement of a fuse by a third party

could cause a serious malfunction of the

vehicle.

Lead-acid starter batteries

These batteries contain harmful

substances (sulphuric acid and lead).

They must be disposed of in accordance

with regulations and must never under any

circumstances be discarded with household

waste.

Installing electrical accessories

The vehicle's electrical system is

designed to operate with standard or optional

equipment.

Before ﬁtting other electrical equipment

or accessories to your vehicle, contact a

CITROËN dealer or a qualiﬁed workshop.

Dispose of used batteries at a designated

collection point.

Protect your eyes and face before

handling the battery.

All operations on the battery must be carried

out in a well ventilated area and away from

naked ﬂames and sources of sparks, to avoid

any risk of explosion or ﬁre.

Theses bulbs are replaced from outside the rear

bumper.

CITROËN accepts no responsibility for

the cost incurred in repairing the vehicle

or for rectifying malfunctions resulting from

the installation of accessories not supplied or

not recommended by CITROËN and not

installed in accordance with its

recommendations, in particular when the

combined power consumption of all of the

additional equipment connected exceeds 10

milliamperes.

Frozen battery

Never try to charge a frozen battery - risk

of explosion!

If the battery has frozen, have it checked by a

CITROËN dealer or by a qualiﬁed workshop,

who will verify that the internal components

have not been damaged and that the case

has not cracked, which could lead to a risk of

leakage of toxic and corrosive acid.

When changing the bulb within a few

minutes of switching oﬀ the ignition, take

care not to touch the exhaust - risk of burns!
