Checking levels


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.


















Oil level

Engine oil change

Refer to the maintenance and warranty guide
for details of the inter val for this operation.
In order to maintain the reliability of the engine
and emission control system, the use of
additives in the engine oil is prohibited.


Oil specifi cation

The oil must be the correct grade for your
engine and conform to the manufacturer's
recommendations.












Brake fluid level


Changing the fl uid

Refer to the maintenance and warranty guide
for details of the inter val for this operation.


Fluid specifi cation

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.

The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel, or using the dipstick.
It will only be correct if the vehicle is on level
ground and the engine has been off for more
than 30 minutes.
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).
It is normal to top up the oil level
between two ser vices (or oil changes).
CITROËN recommends that you check
the level, and top up if necessary, every
3 000 miles (5 000 kms).
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.

Coolant level


The coolant level should be close
to the "MA X" mark but should never
exceed it.
When the engine is warm, the
temperature of the coolant is regulated by the
fan.
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.


Fluid specifi cation

The coolant must conform to the
manufacturer's recommendations.












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. To check the level or top up the
fluid on vehicle fitted with headlamp
washers, immobilise the vehicle and
switch of the engine.

Screenwash / headlamp
wash fluid level







The cooling fan may star t after
switching off the engine: take care
with ar ticles and clothing that might
become caught by the fan blades.

Additive level (Diesel with
particle emissions filter)

Topping up

The reser voir must be topped up without delay
by a CITROËN dealer or a qualified workshop.









Used products

Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.


Open the bonnet and secure it with the
stay.


Open the screenwash reser voir filler cap.


Take and pinch the level gauge to block its
breather.


Remove the gauge completely from
the reser voir to read the level in the
transparent section.


Top up if necessary.


Refit the filler cap to the reservoir and
close the bonnet.


Specifi cation of the fl uid

To ensure optimum cleaning and to avoid
freezing, the fluid should never be topped up or
replaced by plain water.
In wintry conditions, the use of a fluid
with an ethyl alcohol or methanol base is
recommended.
According to your version of instrument panel,
the additive reser voir low level is indicated by:


-
fixed illumination of the par ticle
emissions filter warning lamp,
accompanied by an audible signal and
a message that the particle emissions
filter additive level is too low,

or

- fixed illumination of the ser vice
warning lamp, accompanied by
an audible signal and a message
that the particle emissions filter
additive level is too low.

Checks




















Air filter and passenger compartment filter














Oil filter


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.


Refer to the maintenance and
warranty guide for details of the
replacement inter vals for these
components.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g. city
driving), replace them twice as often if necessar y
.
A clogged passenger compartment filter may have
an adverse effect on the per formance of the air
conditioning system and generate undesirable
odours.


Replace the oil filter each time the
engine oil is changed.
Refer to the maintenance and
warranty guide for details of the
replacement inter val for this
component.





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.













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.
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.

Particle emission filter (Diesel)

On a new vehicle, the first operations of
regeneration of the particle emissions
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 maintenance and
warranty guide for the details of the
level checking inter val for this component.
According to your version of instrument panel, the start of
saturation of the par ticle emissions filter is indicated by:






Electronic gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the maintenance and
warranty guide for details of the
checking inter val for this component.
-
temporary illumination of the ser vice
warning lamp, accompanied by an
audible signal and a message that
there is a risk of blockage of the
particle emissions filter.




- fixed illumination of the par ticle
emissions filter warning lamp,
accompanied by an audible signal
and a message that there is a risk of
blockage of the particle emissions 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 maintenance and
warranty guide for details of the level
checking inter val for this component.

Electric parking brake

This system does not require any
routine ser vicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.















Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.



Brake disc wear

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.






















Manual parking brake

If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between two
services.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
















Brake pads

Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle ser vices.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.

For more information, refer to the "Electric
parking brake - Operating faults" section.
