Checking levels  
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless otherwise indicated.  
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.  
Checking using the dipstick  
Take care when working under the  
bonnet, as certain areas of the engine  
Refer to the "Petrol engine" or "Diesel engine"  
section for the location of the dipstick in the  
engine compartment of your vehicle.  
If you find that the level is above the A mark or  
below the B mark, do not start the engine.  
may be extremely hot (risk of burns)  
and the cooling fan could start at any  
time (even with the ignition off).  
-
If the level is above the MAX mark (risk  
of damage to the engine), contact a  
CITROËN dealer or a qualified workshop.  
If the level is below the MIn mark, you  
must top up the engine oil.  
F

F
Take the dipstick by its coloured grip and  
remove it completely.  
Wipe the end of the dipstick using a clean  
non-fluffy cloth.  
Refit the dipstick and push fully down, then  
pull it out again to make the visual check:  
the correct level is between the marks A  
and B.  
-
Engine oil level  
The check is carried out either when  
the ignition is switched on using the  
oil level indicator in the instrument  
panel for vehicles so equipped, or  
using the dipstick.  
Oil grade  
Before topping-up the oil or changing the oil,  
check that the oil is the correct grade for your  
engine and conforms to the manufacturer's  
recommendations.  
To ensure that the reading is correct,  
your vehicle must be parked on a level  
surface with the engine having been off  
for more than 30 minutes.  
A = MAX  
B = MIN  
It is normal to top up the oil level between  
two services (or oil changes). CITROËN  
recommends that you check the level, and top  
up if necessary, every 3 000 miles (5 000 kms).

Checks  
Brake fluid level  
The brake fluid level should be close  
to the "MAX" mark. If it is not, check  
the brake pad wear.  
Topping up the engine oil level  
Engine oil change  
Refer to the "Petrol engine" or "Diesel engine"  
section for the location of the oil filler cap in the  
engine compartment of your vehicle.  
Refer to the manufacturer's service schedule  
for details of the interval for this operation.  
In order to maintain the reliability of the engine  
and emission control system, never use  
additives in the engine oil.  
F
F
F
Unscrew the oil filler cap to reveal the filler  
aperture.  
Add oil in small quantities, avoiding any  
spills on engine components (risk of fire).  
Wait a few minutes before checking the  
level again using the dipstick.  
Changing the fluid  
Refer to the manufacturer's service schedule  
for details of the interval for this operation.  
F
F
Add more oil if necessary.  
After checking the level, carefully refit the  
oil filler cap and the dipstick in its tube.  
Fluid specification  
The brake fluid must conform to the  
manufacturer's recommendations.  
After topping up the oil, the check when  
switching on the ignition with the oil level  
indicator in the instrument panel is not valid  
during the 30 minutes after topping up.  
Coolant level  
Screenwash fluid level  
Top up the level when necessary.  
The coolant level should be close  
to the "MAX" mark but should never  
exceed it.  
When the engine is warm, the temperature of  
the coolant is regulated by the fan.  
Fluid specification  
The coolant must conform to the  
manufacturer's recommendations.  
Fluid specification  
For optimum cleaning and to avoid freezing,  
this fluid must not be topped up or replaced  
with plain water.  
In wintry conditions, it is recommended that you  
use an ethyl alcohol or methanol based fluid.  
The cooling fan may start after  
switching off the engine: take care  
with articles and clothing that might  
be caught by the fan blades.  
In addition, as the cooling system is  
pressurised, wait at least one hour after  
switching off the engine before carrying out any  
work.  
To avoid any risk of scalding, unscrew the cap  
by two turns to allow the pressure to drop.  
When the pressure has dropped, remove the  
cap and top up the level.

Checks  
diesel additive level (diesel  
engine with particle filter)  
Used products  
Avoid prolonged contact of used oil or  
fluids with the skin.  
Most of these fluids are harmful to  
health or indeed very corrosive.  
The additive reservoir low level is  
indicated by fixed illumination of  
this warning lamp, accompanied by an audible  
warning and a message in the multifunction  
screen.  
Topping up  
This additive must be topped up by a CITROËN  
dealer or a qualified workshop without delay.  
Do not discard used oil or fluids into  
sewers or onto the ground.  
Take used oil to a CITROËN dealer or  
a qualified workshop (France) or to an  
authorised waste disposal site.  
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.  
12 V battery  
Air filter and passenger compartment filter Particle filter (diesel)  
The battery does not require any maintenance.  
Refer to the manufacturer's  
service schedule for details of the  
replacement intervals for these  
components.  
The start of saturation of the  
particle filter is indicated by the  
temporary illumination of this warning lamp  
accompanied by a message in the multifunction  
screen.  
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.  
However, check that the terminals are clean  
and correctly tightened, particularly in summer  
and winter.  
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.  
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 performance  
of the air conditioning system and generate  
undesirable odours.  
If the warning lamp stays on, this indicates a  
low additive level.  
On a new vehicle, the first particle  
filter 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 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.  
Oil 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.

effectiveness of this system is  
noticed, the parking brake must be  
checked, even between two services.  
Checking this system must be done by a  
CITROËN dealer or a qualified workshop.  
Unless there is a leak in the circuit, a drop in  
the brake fluid level indicates that the brake  
pads are worn.  
Electronic gearbox  
The gearbox does not require any  
maintenance (no oil change).  
Brake disc wear  
Only use products recommended by  
CITROËN or products of equivalent  
quality and specification.  
In order to optimise the operation of  
units as important as those in the  
braking system, CITROËN selects and  
offers very specific products.  
Refer to the manufacturer's service  
schedule for details of the checking  
interval for this component.  
For information on checking brake  
disc wear, contact a CITROËN dealer  
or a qualified workshop.  
Automatic gearbox  
The gearbox does not require any  
maintenance (no oil change).  
Refer to the manufacturer's service  
schedule for details of the level  
checking interval for this component.  
After washing the vehicle, dampness,  
or in wintry conditions, ice can form  
on the brake discs and pads: braking  
efficiency may be reduced. Make light  
brake applications to dry and defrost  
the brakes.
