SPEED LIMITER
System which prevents the vehi-
cle from exceeding the speed pro-
grammed by the driver.
Once the limit speed has been
reached, the accelerator pedal no
longer has any effect.
The speed limiter is switched on
manually: a speed of at least 20 mph
(approximately 30 km/h) must be pro-
grammed.
The speed limiter controls are located
on the left-hand side of the steering
wheel. The programmed information is
grouped together in zone
A of the
instrument panel screen.
Steering mounted controls Displays on the instrument
panel
Programming
Rotate the control
1 to the "LIM" po-
sition. With the engine running, you can
adjust the memorised maximum
speed, by means of short or long
presses on:

 button 4 to increase the memo-
rised maximum speed,

 button 2 to decrease the memo-
rised maximum speed.
Successive presses will modify the
maximum speed in steps of 1 mph
(1 km/h) and a sustained press in
steps of 3 mph (5 km/h).
Activation
When the desired maximum speed
is displayed, press button 3 so that
the limitation is activated.
On selection of the
function, the previous
memorised speed and
the information "OFF"
are displayed on the
instrument panel. The information
"OFF"
then disappears from
the instrument panel
screen.
While the function is active, press-
ing the accelerator pedal will not en-
able the programmed speed to be
exceeded, except if you press the
pedal hard down to beyond the end-
of-travel switch.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
The speed limiter cannot, in any circum-
stances, take the place of the obser-
vance of speed limits or of the vigilance
and responsibility of the driver.

Deactivation
Press on button 3 .
This action causes the
information "OFF" to
appear on the instru-
ment panel screen.
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 po-
sition "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 an audible 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 ap-
proved by CITROËN may hinder
access to the accelerator pedal
and thus interfere with the function-
ing 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.

CRUISE CONTROL
System which automatically main-
tains the vehicle speed programmed
by the driver, without any action on
the accelerator pedal.
The cruise control is switched on
manually: the vehicle speed must
be at least 25 mph (approximately
40 km/h) and you must engage:
- fourth gear on a manual gear-box,
- second gear, in sequential mode, on an electronic gearbox or au-
tomatic gearbox,
- position A on an electronic gear-
box or D on an automatic gearbox.
Steering mounted controls
The cruise control switches are lo-
cated on the left-hand side of the
steering wheel. The programmed information is
grouped together in zone
A of the
instrument panel screen.
Displays on the instrument
panel
Activation You can then release the accelerator
pedal. The vehicle will automatically
keep to the speed chosen.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
You can adjust the memorised speed
on the instrument panel screen by
pressing on:

 button 4 to increase the speed,

 button 2 to decrease the speed.
Successive presses modify the cruise
speed in steps of 1 mph (1 km/h) and
a sustained press in steps of 3 mph
(5 km/h).
Deactivation

 Either by pressing on the brake
pedal or on the clutch pedal.

 Or by pressing button 3 .

 Or if either the ESP or the ASR
system is active.
The cruise control is not active if the
gear lever is in neutral.
On selection of the
function via control
1,
no cruise speed has
yet been memorised .
Programming
Rotate the control
1 to the "REG"
position.
Once the desired speed has been
reached using the accelerator, press
button 2 or button 4 . The cruise
speed is then memorised. It is dis-
played in zone A of the instrument
panel. These actions cause
the information
"OFF"
to appear on the instru-
ment panel screen.
These actions do not
cancel the cruise speed
which remains displayed
in the instrument panel.
The cruise control cannot, in any circum-
stances, take the place of the obser-
vance of speed limits or of the vigilance
and responsibility of the driver.

Reactivation

 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 use 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 mes-
sage will display accompanied by
an audible 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.

 By an action on the control 1 from
position "REG" to position 0 .

 By the engine stopping.

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

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 re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
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 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" section).
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesir-
able odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particle filter system (Diesel)
Complementary to the catalytic con-
verter, 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 no-
tice 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 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 conditions
of urban driving of exceptionally 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 interval for this compo-
nent.
The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specifi c 12 V
lead-acid battery with special tech-
nology and specifi cation, for which
the involvement of a CITROËN
dealer is required when replacing or
disconnecting the battery. Failure to observe this recommen-
dation may cause premature wear
of the battery.
