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.

- Never carry out any work on this
system yourself.
- HDi engines make use of advanced
technology.
All maintenance and repairs require
specially trained staff, which only a
CITROËN dealer can provide.

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.

The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).

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.
