Maintenance indicator zero reset Engine oil level indicator
After each service, the maintenance
indicator must be reset to zero.
Your CITROËN technician resets the
indicator to zero after each service.
However, if you do your own servicing,
the procedure for resetting to zero is
as follows :

 switch off the ignition,

 press and hold the trip distance
recorder zero reset button,


switch on the ignition; the distance re-
corder display begins a countdown,

 when the display indicates "=0" ,
release the button; the spanner
disappears. System which informs the driver
whether the engine oil level is cor-
rect or not.
This information is displayed for a
few seconds when the ignition is
switched on, after the service infor-
mation.
The level read will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 15 minutes.
Oil level correct
Oil level low
This is indicated by the fl ashing of

"OIL" , accompanied by an audible
signal and a message on the multi-
function screen.
If the low oil level is confi rmed by a
check using the dipstick, it is essen-
tial that the level is topped up to pre-
vent damage to the engine. Oil level gauge fault
This is indicated by the fl ashing of

"OIL--" . Contact a CITROËN dealer.
Dipstick
Refer to the "Checks" section to lo-
cate the dipstick and the oil fi ller cap
on your engine. There are 2 marks on
the dipstick:
- A = max; never ex-
ceed this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.
Following this operation, if you wish
to disconnect the battery, lock the
vehicle and wait at least fi ve minutes
for the zero reset to be taken into ac-
count.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Oil level
Draining the engine
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er’s recommendations.
Brake fluid level
Draining the circuit
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-
larly. Fluid which has been used for
too long may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer’s recommendations
and fulfi l the DOT4 standards.
Coolant level
Draining the circuit
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer’s recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
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. This can oper-
ate with the ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
gine is cold.
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, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

Screenwash and headlamp
wash fluid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with plain water.
Reservoir capacities:
-
screenwash: approximately 3 litres,
- screenwash and headlamp wash: approximately 6 litres. Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to an authorised
waste disposal site.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible sig-
nal and a message on the multifunc-
tion screen.
Top up the level when you next stop
the vehicle.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your en-
gine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection. Air filter and passenger
compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
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
(refer to the "Engines" paragraph).
A clogged cabin fi lter may have an
adverse effect on the performance
of the air conditioning system and
generate undesirable odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particulate filter system
(Diesel)
Complementary to the catalytic
converter, this fi lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice 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 clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble signal and lighting of the serv-
ice warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in condi-
tions of urban driving of excep-
tionally long duration: low speeds,
traffi c jams etc.) .
To regenerate the fi lter, it is advised
to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer.
Refer to the Maintenance and
Warranty Guide for details of
the replacement interval for this
component.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
6-speed electronic gearbox
system The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire any maintenance (no
oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake If the parking brake travel is
too long or if a loss of effec-
tiveness of this system is
noticed, the parking brake
must be adjusted, even be-
tween two services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent qual-
ity and specifi cations.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
Refer to the Maintenance and
Warranty Guide for the details of the
level checking interval for this com-
ponent.
