the location of various engine components needed to check the levelsand the main wearing parts.

183Checks








Bonnet
Protects the components of the engine and provides access for checking levels.


Opening
)Open the front left door.)Pull the interior release lever A
, located at
the bottom of the door aper ture.
) Push the exterior safety catch Bto the leftand raise the bonnet. )
Unclip the bonnet stay Cfrom its housing, holding it by its foam protection.)

transparent pipe under the bonnet.
)Fill the fuel tank with at least five litres of
Diesel.)Open the bonnet. )Depending on version, unclip the cover togain access to the priming pump.)Squeeze and release the priming pump
until resistance is felt (could be from the
first application) and fuel appears in the
transparent pipe with the green connector. )Operate the star ter until the engine star ts.)Depending on version, put the cover back in position and clip it in place.)Close the bonnet.
If the engine does not star t at the firstattempt, do not try again. Operate the priming pump again, thenthe starter.

Checks




























Checking levels
Check all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops si
gnificantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.


Oil level
Engine oil change
Refer to the servicing booklet for details of theinterval 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 grade
The oil must be suitable for your engine and conform to the manufacturer'srecommendations.



Brake fluid level


Changing the fl uid

Refer to the servicing booklet for details of the
interval for this operation.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet theDOT4 standard.
Th
e brake fluid level should be closeto 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 than30 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.
It is normal to top up the engine oil between services. CITROËNrecommends 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.


Fluid specifi cation

The coolant must conform to the
manufacturer's recommendations.



Screenwash fluid level


Fluid specifi cation

For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.

Take care when carrying out checks under the bonnet as some parts of theengine can be very hot (risk of burns).

Coolant level
Top up the level when necessary.
Th
e 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 particle emission filter, 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, 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.
