bonnet open.
Closing
)
Take the stay out of the support
notch.
)
Clip the stay in its housing.
)
Lower the bonnet and release it at
the end of its travel.
)
Pull on the bonnet to check that it is
secured correctly.
)
Open the front left door.
)
Pull the interior bonnet release le-
ver A
, located at the bottom of the
door aperture.
The location of the interior bon-
net release lever prevents open-
ing of the bonnet while the front
left door is closed.
Opening
Before doing anything under the
bonnet, switch off the Stop &
Start system to avoid any risk of
injury resulting from an automat-
ic change to START mode. Do not open the bonnet in high
winds.
When the engine is hot, handle
the exterior safety catch and the
bonnet stay with care (risk of
burns).

CHECKS
RUNNING OUT OF FUEL (DIESEL)
If your vehicle is fi tted with an HDI en-
gine, the fuel system must be primed if
you run out of fuel.
This system consists of a priming pump
and a transparent pipe under the bonnet.
)
Fill the fuel tank with at least fi ve litres
of Diesel.
)
Open the bonnet.
)
Depending on version, unclip the
cover to gain access to the priming
pump.
)
Squeeze and release the priming
pump until resistance is felt (could
be from the fi rst application) and fuel
appears in the transparent pipe with
the green connector.
)
Operate the starter until the engine
starts.
)
Depending on version, put the cover
back in position and clip it in place.
)
Close the bonnet.
If the engine does not start at the
fi rst attempt, do not try again.
Operate the priming pump again,
then the starter.

CHECKS
CHECKING LEVELS
Brake fluid level
Oil level
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.
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fl uid
Refer to the servicing booklet for details
of the interval for this operation.
Coolant level
The coolant level should be
close to the "MAX" 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 fi tted with a par-
ticle emission fi lter, the fan may operate
after the vehicle has been switched off,
even if the engine is cold.
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with plain water.
Engine oil change
Refer to the servicing booklet for details
of the interval 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.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.
Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.
Changing the coolant
The coolant does not have to be changed.
Screenwash fluid level
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop. 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 pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
Top up the level when necessary.
Take care when carrying out
checks under the bonnet as
some parts of the engine can be
very hot (risk of burns).
It is normal to top up the engine oil
between services. CITROËN rec-
ommends that you check the oil
level and top up if necessary, every
3 000 miles (5 000 kilometres).

CHECKS
Avoid prolonged contact of used
oil or fl uids with the skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or fl uids
into sewers or onto the ground.
Take used oil to a CITROËN
dealer or a qualifi ed workshop
(France) or to an authorised
waste disposal site.
Diesel additive level (Diesel engine
with particle emission filter)
Used products CHECK
S
Batter
y
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, re-
fer to the "Practical information" section for
details of the precautions to be taken before
disconnecting the battery and following its
reconnection.
Air filter and passenger compartment filter
Refer to the servicing booklet
for details of the replacement
intervals 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 neces-
sary
(refer to the "Engines" section).
A clogged passenger compartment fi lter
may have an adverse effect on the per-
formance of the air conditioning system
and generate undesirable odours.
Oil filter
Replace the oil fi lter each time
the engine oil is changed.
Refer to the servicing booklet
for details of the replacement
interval for this component.
Topping up
This additive must be topped up by a
CITROËN dealer or a qualifi ed work-
shop without delay.
Unless otherwise indicated, check these
components in accordance with the servic-
ing booklet and according to your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed workshop.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and speci-
fi cation, for which the involvement of a
CITROËN dealer or a qualifi ed work-
shop is required when replacing or dis-
connecting the battery.
Failure to observe this recommendation
may shorten the life of the battery. The additive reservoir low
level is indicated by fi xed illu-
mination of this warning lamp,
accompanied by an audible warning and
a message in the multifunction screen.

CHECKS
Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.
In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.
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 qualifi ed work-
shop.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the servicing booklet for
the details of the level checking
interval for this component.
For information on checking
brake disc wear, contact a
CITROËN dealer or a qualifi ed
workshop.
Brake disc wear
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 services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.
Brake pads
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the servicing booklet
for details of the checking in-
terval for this component.
Electronic gearbox
Particle emission filter (Diesel)
The start of saturation of the
particle fi lter is indicated by
the temporary illumination
of this warning lamp accompanied by a
message in the multi-function screen.
As soon as the traffi c conditions per-
mit, regenerate the fi lter 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 indi-
cates a low additive level.
On a new vehicle, the fi rst par-
ticle fi lter regeneration opera-
tions 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 excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment.
