BONNET
Protects the components of the en-
gine and provides access for check-
ing levels.
Opening
 Push the exterior safety catch B
to the left and raise the bonnet.

 Unclip the stay C from its housing.

 Fix the stay in the notch to hold
the bonnet open. Closing

 Take the stay out of the support
notch.

 Clip the stay in its housing.

 Lower the bonnet then slam it
home at the end of its travel.

 Pull on the bonnet to check that
it is fully closed.
The location of the interior release
lever prevents opening of the
bonnet while the driver's door is
closed.
This operation must only be carried
out when the vehicle is stationary.
Avoid opening the bonnet in strong
winds.
When the engine is hot, take care
when handling the exterior safety
catch and the bonnet stay (risk of
burns).

 Open the driver's door.

 Pull the interior release lever A ,
located at the bottom of the door
frame.

RUNNING OUT OF FUEL (DIESEL)
HDi 138 engine
Detach the protective cover for access
to the priming pump. HDi 110 engine
Detach the protective cover for access
to the priming pump. Priming the fuel circuit
In the event of running out of fuel:

 after fi lling (minimum 5 litres),
squeeze the manual priming
pump repeatedly, until some re-
sistance is felt,

 then operate the starter, gently
pressing the accelerator until the
engine starts.
If the engine fails to start at the fi rst
attempt, wait 15 seconds before
trying again.
If the engine fails to start after a few
attempts, repeat the procedure from
the beginning. When the engine is
idling, accelerate gently to complete
the purge of the circuit.
HDi engines are of a highly
technical nature.
All maintenance and re-
pairs require specifi c qualifi cations
which only your CITROËN dealer
can guarantee.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Take care when working under the
bonnet, as some parts of the engine
can be extremely hot (risk of burns).
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation The oil must correspond to your en-gine and conform to the manufacturer's
recommendations.
Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-
larly. Fluid which has been used for
too long may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Coolant change
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
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 regu-
lated by the fan. This can operate with
the ignition off.

On vehicles which are fi tted with
a particle emission fi lter, 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, un-
screw the cap by two turns to allow
the pressure to drop. When the pres-
sure has dropped, remove the cap
and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

Screenwash and headlamp
wash fluid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with plain water.
Reservoir capacities:
-
screenwash: approximately 3 litres,
- screenwash and headlamp wash: approximately 6 litres. Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
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
(France) or an authorised waste
disposal site.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible signal
and a message on the multifunction
screen.
Top up the level when you next stop
the vehicle.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not require
any maintenance.
However, check that the
terminals are clean and
correctly tightened, par-
ticularly in summer and
winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion 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 Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
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" paragraph).
A clogged cabin fi lter may have an
adverse effect on the performance
of the air conditioning system and
generate undesirable odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particle filter system (Diesel)
Complementary to the catalytic
converter, this fi lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at
very low speeds, you may occa-
sionally notice water vapour being
emitted from the exhaust when ac-
celerating. This is of no consequence
to the running of the vehicle or to the
environment.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble signal and lighting of the service
warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in condi-
tions of urban driving of excep-
tionally long duration: low speeds,
traffi c jams etc.)
To regenerate the fi lter, it is advised
to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer.
Refer to the Maintenance and Warranty
Guide for details of the replacement in-
terval for this component.

C H E C K S
Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles 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.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
6-speed electronic gear
control gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake
If a loss of effectiveness of this sys-
tem is noticed, the parking brake
must be checked, even between two
services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent quality
and specifi cations.
In order to optimise the operation
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 compartment is
strictly prohibited .
Refer to the Warranty and
Maintenance Record for the details
of the level checking interval for this
component.
