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.
12 V battery
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 battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.
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.

Range indicators
When switching on the ignition, an indicator
gives an estimate of the distance that can
be travelled with your vehicle before engine
starting is automatically prevented, once the
vehicle starts using the reserve of AdBlue
® or
after a fault is detected with the SCR system.
In the event of simultaneous system fault and
low AdBlue
® level, the shortest range is the one
displayed.
In the event of the risk of non-starting related to a lack of AdBlue®
