RUNNING OUT OF FUEL (DIESEL)
HDi 138 engine
Detach the protection cover to gain
access to the priming pump. HDi 110 engine
Detach the protection cover to gain
access to the priming pump. Priming the fuel circuit
In the event of running out of fuel:
a f t e r fi l l i n g ( m i n i m u m 5 l i t r e s ) ,
action the manual priming pump,
until some resistance is felt,
then action the starter, gently
pressing the accelerator until the
engine starts.
I f t h e e n g i n e f a i l s t o s t a r t a t t h e fi r s t
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 repairs re-

Oil level
Draining the engine
Refer to the servicing booklet for
details of the interval for this opera-
tion. O i l s p e c i fi c a t i o n
The oil must correspond to your
engine and conform to the manufac-
turer's recommendations.
Brake fluid level

details of the interval for this opera-
tion.

Coolant level
Draining the circuit
The coolant does not have to be
changed.
F l u i d s p e c i fi c a t i o n
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.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. T h e b r a k e fl u i d l e v e l s h o u l d
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 tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

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.
In order to maintain the
reliability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and in
relation 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, parti-
cularly in summer and winter.
When carrying out work on the bat-
t e r y , r e f e r t o t h e " P r a c t i c a l i n f o r -
mation" section for details of the
precautions to be taken before dis-
connecting 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 necessary
(refer to the "Engines" paragraph).

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 occasionally
notice water vapour being emitted
from the exhaust when accelerat-
ing. 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 a sound
signal and lighting of the service
warning lamp.
This alert tells you that the particle

Brake pads Brake wear depends on
the style of driving, par-
ticularly 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
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s
that the brake pads are worn.
Manual gearbox
The gearbox does not
require any maintenance
(no oil change).
6-speed electronic gearbox
system
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 status
For information relating to
checking the brake disc
wear status, contact a
CITROËN dealer.
Handbrake
If the handbrake travel is too long
or if a loss of effectiveness of this
system is noticed, the handbrake
must be adjusted, 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

In order to optimise the operation
of units as important as the braking
system, CITROËN selects and

To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
