Checking levels
Check all of the following levels regularly in 
accordance with the manufacturer's service 
schedule. Top them up if required, unless 
otherwise indicated.
If a level drops significantly, have the 
corresponding system checked by a CITROËN 
dealer or a qualified workshop.
The fluids must comply with the  manufacturer's requirements and with 
the vehicle's engine.
Take care when working under the  bonnet, as certain areas of the engine 
may be extremely hot (risk of burns) and the 
cooling fan could start at any time (even with 
the ignition off).
Used products
Avoid prolonged contact of used oil or  fluids with the skin.
Most of these fluids are harmful to health and 
very corrosive.
Do not discard used oil or fluids into 
sewers or onto the ground.
Empty used oil into the containers reserved 
for this purpose at a CITROËN dealer or a 
qualified workshop.
Engine oil
The level is checked, with the engine  having been switched off for at least 30 
minutes and on level ground, either using the oil 
level indicator in the instrument panel when the

Practical information
7Once the pressure has dropped, remove the cap 
and top up to the required level.
Vehicle with electric motorDo not top up the coolant. 
If the level is close to or below 
the  "MIN"   mark, it is essential to contact a 
CITROËN dealer or a qualified workshop.
Screenwash fluid
Top up to the required level when  necessary.
Capacity of the tank:
–
 
5.3 litres for "very cold climate" versions.
–
 
2.2 litres for other versions.
Fluid specification
The fluid must be topped up with a pre-mixed 
product.
In winter (temperatures below zero), a fluid 
containing an anti-freeze agent which is 
appropriate for the temperature conditions 
must be used in order to protect the system's 
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all 
circumstances (risk of freezing, 
limescale, etc.).
Diesel fuel additive (Diesel 
with particle filter)
On reaching the minimum level in 
the particle filter additive tank, one 
of these warning lamps comes on fixed, 
accompanied by an audible signal and a warning 
message.
Topping up
The topping up of this additive must be carried 
out quickly.
Visit a CITROËN dealer or a qualified workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is 
reached.
For more information on the  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 the supply of AdBlue, refer to 
the corresponding section.
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.
Only use products recommended by 
CITROËN or products of equivalent 
quality and specification.
In order to optimise the operation of 
components as important as those in the 
braking system, CITROËN selects and offers 
very specific products.
12 V battery
The battery does not require any  maintenance.
Check regularly that the terminals are correctly 
tightened (versions without quick-release 
terminals) and that the connections are clean.
For more information on the precautions 
to take before any work on the 12   V 
battery, refer to the corresponding section.
Versions equipped with Stop & Start are 
fitted with a 12   V lead-acid battery with 
special technology and specifications.
Its replacement should be carried out only by 
a CITROËN dealer or a qualified workshop.
