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.

)

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 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 grade

The oil must be suitable 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 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.
It is normal to top up the engine
oil between 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.


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 water.



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



Coolant level

Top up the level when necessary.
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.

185Checks









Diesel additive level
(Diesel engine with particle
emission filter)

Topping up

This additive must be topped up by a CITROËN
dealer or a qualified workshop without delay.











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. A additive reser voir low level is
indicated by fixed illumination of
this warning lamp, accompanied by an audible
warning and a message in the multifunction
screen.

Checks


Battery Air filter and passenger compartment filter


Oil filter








Par ticle emission filter (Diesel)

Unless other wise indicated, check these components in accordance with the Warranty and Maintenance Record and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
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 "Practical information" section for details of
the precautions to be taken before disconnecting
the battery and following its reconnection.


Refer to the Warranty and
Maintenance Record 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
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 Warranty and
Maintenance Record 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
technology and specification, for which the
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. The star t of saturation of the
par ticle filter is indicated by the
temporary illumination of this warning lamp
accompanied by a message in the multi-
function screen.
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, this indicates a
low additive level.

On a new vehicle, the first par ticle
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.

Automatic gearbox














Brake pads

Brake wear depends on the style
of driving, par ticularly in the case
of vehicles used in town, over shor t
distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake
pads are worn. The gearbox does not require any
maintenance (no oil change).
Refer to the Warranty and Maintenance
Record for the details of the level
checking interval for this component.


Brake disc wear
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.






















Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation
of units as impor tant as the braking
system, CITROËN selects and offers
very specific products.
To avoid damaging the electrical units,
the use of a high pressure washer
in the engine compar tment is strictly
prohibited
.
The gearbox does not require any
maintenance (no oil change).
Refer to the Warranty and Maintenance
Record for details of the level checking
interval for this component. For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.













SensoDrive gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the Maintenance and
Warranty Guide for details of the
checking interval for this component.
