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, at the same time as the servicing
information.
Engine oil level indicator*
The level read will only be correct if
the vehicle is on level ground and the
engine has been off for more than
30
m
inutes.
Oil level correct
Oil level incorrect
This is indicated by the flashing of " OIL" or the
display of a message, accompanied by the
service warning lamp and an audible signal.
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.
Oil level indicator fault
This is signalled by the flashing of " OIL- -" or
the display of a message.
Contact a CITROËN dealer or a qualified
workshop.
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.
* Depending on version.

Checking levels
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.
Engine oil level
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).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.
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).
Checking using the dipstick
F Locate the dipstick in the engine
compartment of your vehicle.
For more information on the petrol or Diesel
engine, refer to the corresponding section.
F
T
ake the dipstick by its coloured grip and
remove it completely.
F
W
ipe the end of the dipstick using a clean
non-fluffy cloth.
F
R
efit 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 = MA X
B = MIN If you find that the level is above the A mark or
below the B mark, do not star t the engine
.
-
I
f the level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-
I
f the level is below the MIN mark, you
must top up the engine oil.
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.
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.
Checks

Power steering fluid level
The power steering fluid level should
be close to the "MA X" mark. With
the engine cold, unscrew the cap to
check the level.
Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Topping-up the engine oil level
F Locate the oil filler cap in the engine
compartment of your vehicle.
For more information on the petrol or Diesel
engine, refer to the corresponding section.
F

aperture.
F

fter 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.

Particle filter (diesel)
On a new vehicle, the first operations
of regeneration of the particle filter
may be accompanied by the smell of
"burning", which is per fectly 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.
Manual 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.According to your version of instrument panel, the start of
saturation of the particle emissions filter is indicated by:
- temporary illumination of the service warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of
the particle filter.
-
f
ixed illumination of the particle
filter warning lamp, accompanied
by an audible signal and a
message that there is a risk of
blockage of the particle filter,
or
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.
If the warning lamp stays on, refer to the
"Additive level" section.
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.
