Checks

Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and
offers very specific products.

12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections
are clean.
For more information on the precautions to
take before any work on the 12 V battery,
refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.

Cabin filter

Depending on the environment and
the use of the vehicle (e.g. dusty
atmosphere, city driving), change it
twice as often if necessary.
A clogged cabin filter may have an
adverse effect on the performance of
the air conditioning system and generate
undesirable odours.
Air filter
Depending on the environment and
the use of the vehicle (e.g. dusty
atmosphere, city driving), change it
twice as often if necessary.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is signalled by the temporary
illumination of this warning lamp,
accompanied by a message warning
or
of the risk of the filter clogging up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
