Checks

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.
12 V battery
The battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.
When carrying out work on the battery, refer
to the "12 V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.
The presence of this label, in particular with
the Stop & Start system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification. The involvement
of a CITROËN dealer or a qualified workshop
is essential when replacing or disconnecting
the battery.

Air filter and passenger compartment filter
Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g. city
driving), replace them twice as often if necessary.
A clogged passenger compartment filter may have
an adverse effect on the performance of the air
conditioning system and generate undesirable
odours.

Oil filter

Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Particle filter (Diesel)
The start of saturation of the
particle filter is indicated by the
fixed illumination of this warning
lamp accompanied by a warning
message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, this
indicates a low additive level.
Refer to the "diesel additive level"
section.
on a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is perfectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
