Anti-theft protection
Electronic engine immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.For reasons of safety and theft protection,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it on
your person.
In the event of a malfunction, you are informed
by a message in the instrument panel screen.
In this case, your vehicle does not start; contact
a CITROËN dealer if required.
Starting / Switching off the engine with the key
It has 3 positions:
-
position 1 (Stop): insert and removing the
key, steering column locked,
-
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
-
position 3 (Starting) .
Ignition switch
Switching off the engine leads to a loss
of braking assistance.
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reserve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preserve the remaining
battery charge.
Avoid attaching heavy objects to the
key or the remote control, which would
weigh down on its blade in the ignition
switch and could cause a malfunction.
It could adversely affect the deployment
of the front airbag.

carried out only by a CITROËN dealer
or a qualified workshop.
For more information on the 12 V
Battery , refer to the corresponding
section.
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid the risk of injury related to an
automatic change to START mode. Opening the bonnet

Checking components
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.Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment 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.
Oil filter
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.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 per formance
of the air conditioning system and generate
undesirable odours.
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.
For more information on Checking levels and
the Diesel additive level in particular, refer to
the corresponding section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly 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.
For more information and the precautions to
take before starting work on the 12 V batter y
,
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.
