Practical information
The check and top-up must only be done with the
engine cold.
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
12 V battery
The battery does not require any
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the "MAX"
mark but should never exceed it.
If the level is close to or below the "MIN” mark, it
is essential to top up.
maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue® (BlueHDi), and
in particular on the supply of AdBlue, refer to the
corresponding section.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.
In order to avoid the risk of scalding if you need to
top up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow the
pressure to drop.
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
dealer or by a qualified workshop.
Once the pressure has dropped, remove the cap
and top up to the required level.

driving), change it twice as often, if necessary.
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate undesirable
odours.
Otherwise, have them checked by a dealer or a
qualified workshop.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Only use products recommended by the
Manufacturer or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, the Manufacturer selects and
offers very specific products.
