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 with an electric oil
level gauge, or using the dipstick.
Checking using the dipstick
A = MA X
Check all of these levels regularly, in line with the maintenance and warranty guide. 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.
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). B = MINIf you find that the level is above the A mark or
below the B mark, do not star t the engine
.

mark (risk
of damage to the engine), contact a

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.
Refer to the "Petrol engine" or "
di

esel engine"
section for the location of the dipstick in the
engine compartment of your vehicle.

Brake fluid level
The brake fluid level should be close
to the "MaX" mark. If it is not, check
the brake pad wear.
Changing the fluid
Refer to the maintenance and warranty guide
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
Topping up the engine oil level
Refer to the "Petrol engine" or "di esel engine"
section for the location of the oil filler cap in the
engine compartment of your vehicle.

indicator in the instrument panel is not valid
during the 30 minutes after topping up.
Engine oil change
Refer to the maintenance and warranty guide
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.

Checks

146
Coolant level
The coolant level should be close
to the "MaX" mark but should never
exceed it.
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.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.
Changing the coolant
The coolant does not have to be replaced at
routine services.
Screenwash fluid level
When the engine is warm, the temperature of
the coolant is regulated by the fan. Top up the level when necessary.
The cooling fan may star t after switching
off the engine: take care with ar ticles 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.
Diesel additive level

emission filter) Used products

dealer or a qualified workshop without delay.

fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
do n
ot discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITR
oËn
dealer or
a qualified workshop (France) or to an
authorised waste disposal site.
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.
Checks

147
Particle filter (Diesel)
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.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
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.
Checks
12 V battery
The battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.
Air filter and passenger compartment filter
Refer to the maintenance and
warranty guide for details of the
replacement intervals for these
components.
Oil filter
Replace the oil filter each time the
engine oil is changed.
Refer to the maintenance and
warranty guide for details of the
replacement interval for this
component.
Unless other wise indicated, check these components in accordance with the maintenance and warranty guide and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
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.
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.
de

pending 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 c

logged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
as s
oon 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, this indicates a
low additive level.
