Deactivation
Press on button 3 .
This action causes the
information "OFF" to
appear on the instru-
ment panel display.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A of the
instrument panel.
Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again. Return to normal driving

 By moving the control 1 from
position "LIM" to position 0 .

 By the engine stopping.
The speed previously chosen is still
memorised. Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by a sound signal and lighting
of the service warning lamp.
Have it checked by a CITROËN
dealer.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for exam-
ple on a steep descent or under heavy
acceleration) then the speed fl ashes.
Adapt your speed as necessary.
The function will re-engage when
your speed returns below the de-
sired maximum speed.
On a steep downhill gradi-
ent or on sharp accelera-
tion, the speed limiter will
not be able to prevent the vehicle
from exceeding the programmed
speed.
Use of fl oor mats that are not
approved by CITROËN may hinder
access to the accelerator pedal and
thus interfere with the functioning
of the speed limiter.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor- rectly positioned,
- never use more than one fl oor mat.

 By recall of the memorised
speed
After a disengagement, press on button 3 . Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A .
If the memorised cruise speed is higher than the current speed,
the vehicle will accelerate to
reach the former.

 By selection of the current
speed
Press on button 2 or 4 once the
desired speed has been reached.
The information "OFF" will then
disappear from the instrument
panel display.
Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to action
the accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone A fl ashes.
You have only to release the accel-
erator pedal to return to the cruise
speed. If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
then the speed fl ashes. Adapt your
speed as necessary.
Return to normal driving Operating fault
If there is a malfunction, a message
will display accompanied by a sound
signal and lighting of the service
warning lamp.
Have it checked by a CITROËN dealer.
Cruise control should only
be used when the driving
conditions allow you to drive
at a constant speed.
Do not use it in heavy traffi c, or on
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to keep your
feet within range of the pedals.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor- rectly positioned,
- never use more than one fl oor mat.

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 circuit checked by a
CITROËN dealer.
Oil level
Draining the engine
Refer to the servicing booklet for de-
tails of the interval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Draining the circuit
Refer to the servicing booklet for de-
tails of the interval for this operation.
This fl uid must be changed regularly.
Fluid which has been used exces-
sively 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
Draining the circuit
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.
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. 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
regulated by the fan. This can oper-
ate 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,
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 re-
liability 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 re-
lation to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire 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.
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).
A clogged passenger compartment
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. Particulate filter system
(Diesel)
Complementary to the catalytic
converter, this fi lter makes an active
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 accelerating. 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
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 servicing booklet for
details of the replacement interval
for this component.
