Checking levels

Check all of these levels regularly and 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 ser vicing booklet for 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 correspond to your engine
and conform to the manufacturer's
recommendations.



Brake fluid level


Changing the fl uid

Refer to the Maintenance and Warranty Guide
for the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to the
manufacturer's recommendations and meet
the DOT4 standard.
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more than
30 minutes.
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.
When working under the bonnet, take
care, as cer tain areas of the engine
may be extremely hot (risk of burns).
It is normal to top up the oil level
between two ser vices. CITROËN
recommends that you check the oil
level, and top up if necessary, every
3 000 miles (5 000 kilometres).

Changing the coolant

The coolant does not have to be changed.


Coolant specifi cation

The coolant must conform to the
manufacturer's recommendations.



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. This can operate with the ignition off.

On vehicles which are fitted with a par ticle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine 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, 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.

Power steering fluid level

The power steering fluid level should
be close to the "MA X" mark. Unscrew
the cap, with the engine cold,
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.

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.
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 par ticle emissions filter
additive level is too low.

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" section).
A clogged passenger compar tment 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 servicing booklet for
details of the replacement inter val for
this component.





The presence of this label, in particular with
the Stop & Star t system, indicates the use of
a specific 12 V lead-acid battery with special

involvement of a CITROËN dealer or a qualified
workshop is required when replacing or
disconnecting the battery.
Failure to obser ve this recommendation may
shor ten the life of the battery.
