Engine oil level indicator*
on versions fitted with an electric oil level 
indicator, the state of the engine oil level is 
displayed in the instrument panel for a few 
seconds, after the servicing information.Oil level correct
This is indicated by the display of the message 
"Oil level incorrect" in the instrument panel 
screen, accompanied by the service warning 
lamp and an audible signal.
Oil level indicator fault
* Depending on version. In the event of a fault with the electric 
indicator, the oil level is no longer 
monitored.
If the system is faulty, you must check 
the engine oil level using the manual 
dipstick located under the bonnet.
Refer to the "Checking levels" section.
Oil level incorrect
This is signalled by the display of the message 
"Oil level measurement invalid" in the 
instrument panel.
Contact a CITROËN dealer or a qualified 
workshop.
If the low oil level is confirmed by a 
check using the dipstick, the level 
must be topped up to avoid damage to 
the  engine.
Refer to the "Checking levels" section.
The level read will only be correct if 
the vehicle is on level ground and the 
engine has been off for more than 
30
 minutes.

Checking levels
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.
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
If you find that the level is above the A mark or 
below the B mark, do not star t the engine.
-  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.
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).
To ensure that the reading is correct, your 
vehicle must be parked on a level sur face 
with the engine having been off for more than 
30  minutes.
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).
Checking using the dipstick
F  Locate the dipstick in the engine 
compartment of your vehicle.
Refer to the "Petrol engine" or "Diesel engine" 
section.
F  Take the dipstick by its coloured grip and 
remove it completely.
F  Wipe the end of the dipstick using a clean 
non-fluffy cloth.
F  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 .
A = MaX
B = MI n

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.
Topping up the engine oil level
F Locate the oil filler cap in the engine 
compartment of your vehicle.
Refer to the "Petrol engine" or "Diesel engine" 
section.
F  Unscrew the oil filler cap to reveal the filler 
aperture.
F  Add oil in small quantities, avoiding any 
spills on engine components (risk of fire).
F  Wait a few minutes before checking the 
level again using the dipstick.
F  Add more oil if necessary.
F  After checking the level, carefully refit the 
oil filler cap and the dipstick in its tube.
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.
Engine oil change
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.

Manual gearbox
The gearbox does not require any 
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any 
maintenance (no oil change).
Refer to the manufacturer's service schedule 
for the checking interval for this component.
Refer to the manufacturer's service schedule 
for details of the level checking interval for this 
component.
Particle filter system 
(Diesel)
Complementary to the catalytic converter, 
this filter makes an active contribution to the 
preservation of air quality by trapping unburnt 
pollutant particles. Black exhaust fumes are 
thus no longer emitted.
After prolonged idling or driving at very low 
speeds, you may occasionally notice water 
vapour being emitted from the exhaust when 
accelerating. This is of no consequence to the 
running of the vehicle or to the environment. If there is risk of blockage, a message 
appears in the instrument panel screen, 
accompanied by an audible signal and 
illumination of the service warning lamp.
This alert tells you that the particle filter 
is approaching saturation (in conditions 
of urban driving of exceptionally long 
duration: low speeds, traffic jams etc.)
To regenerate the filter, it is advised to 
drive as soon as possible, when traffic 
conditions permit, at a speed of 40 mph 
(around 60 km/h) or more for at least 
five minutes (until the alert message 
disappears).
If this alert persists, contact a CITR
oËn 
dealer or a qualified workshop.
