Checks
Unless otherwise indicated, check these
components in accordance with the servicing
booklet and according to your engine.
Other wise, have them checked by a CITROËN
dealer or a qualified workshop.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off)to avoid any risk of injury resulting from automatic operation of the engine.The presence o
f 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.
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 carr
ying out work on the battery, refer
to the "Practical information" section for
details of the precautions to be taken before
disconnectin
g the battery and following its reconnection.

Particle emission filter (Diesel)
The start of saturation of theparticle filter is indicated bythe temporary illumination of
this warning lamp accompanied by a message
in the multi-function screen.
As soon as the traffic conditions permit, regenerate the filter by driving at aspeed 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.


On a new vehicle, the first par ticlefilter 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.
The 100% electric mode is not available during regeneration of the par ticle emissions filter.
Air filter and passenger compartment filter
Oil filter

Replace the oil filter each time the engine oil is changed.

Brake wear depends on the st
yle
of driving, par ticularly in the case
of vehicles used in town, over shor tdistances. It may be necessary tohave the condition of the brakes checked, evenbetween vehicle services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brakepads are worn.
