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 (around 30 km/h) must be
programmed.
The speed limiter cannot, in any cir-
cumstances, take the place of the
observance of speed limits or of the
vigilance and responsibility of the
driver.
Steering wheel controls
The speed limiter controls are lo-
cated on the left-hand side of the
steering wheel.
Displays on the instrument panel
The programmed information is
grouped together in zone A of the
instrument panel display.
Programming
Rotate the control 1 to the "LIM" po-
sition.
On selection of the function, the
previous memorised speed and the
information "OFF" are displayed on
the instrument panel.
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
and a sustained press in steps of
3 mph. Activation
When the desired maximum speed
is displayed, press button
3 so that
the limitation is activated.
The information "OFF" then disappears from the instrument panel display.
While the function is active, pressing
the accelerator pedal will not enable
the programmed speed to be ex-
ceeded, 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.
Deactivation
Press on button 3 .
This action causes the information

"OFF" to appear on the instrument
panel display.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A of the
instrument panel.

D R I V I N G
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.
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. 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.
On a steep downhill gradient or on
sharp acceleration, the speed limiter
will not be able to prevent the vehi-
cle 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 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.

D R I V I N G
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 (approx. 40 km/h)
and you must engage:
- fourth gear on a manual gearbox,
- second gear, in sequential mode, on an electronic gearbox or
automatic gearbox,
- position A on an electronic
gearbox or D on an automatic
gearbox.
The cruise control cannot, in any
circumstances, take the place of the
observance of speed limits or of the
vigilance and responsibility of the
driver. Steering wheel controls
The cruise control switches are
located on the left-hand side of the
steering wheel.
Displays on the instrument panel
The programmed information is
grouped together in zone
A of the
instrument panel display. Programming
Rotate the control
1 to the "REG"
position.
Activation
On selection of the function via con-
trol 1, no cruise speed has yet
been memorised.
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.
You can then release the accelera-
tor pedal. The vehicle will automati-
cally 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 display 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 and a
sustained press in steps of 3 mph.

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.
These actions cause the information

"OFF" to appear on the instrument
panel display.
These actions do not cancel the
cruise speed which remains dis-
played in the instrument panel.
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 acce-
lerator pedal to return to the cruise
speed.
Return to normal driving

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

 By the engine stopping.
The cruise speed previously chosen
is no longer memorised. Operating fault
If there is a malfunction, a message
will display accompanied by an
audible signal and lighting of the
service warning lamp.
Have it checked by a CITROËN
dealer.
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. 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.

LANE DEPARTURE WARNING SYSTEM
System which detects the involun-
tary crossing of longitudinal traffi c
lane markings on the ground (solid
or broken line).
Sensors, fi tted below the front
bumper, trigger a warning if the vehi-
cle drifts over a lane marking (speed
higher than 50 mph (80 km/h)).
This system is particularly useful on
motorways and main roads. Activation

 Press button A , the indicator
lamp comes on.
Deactivation

 Press button A again, the indica-
tor lamp switches off.
The status of the system remains
in the memory when the ignition is
switched off.
Detection
You are warned by the vibration of
the driver's seat cushion:
- on the right-hand side, if the marking on the ground has been
crossed on the right,
- on the left-hand side, if the mark- ing on the ground has been
crossed on the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the
direction indicator is switched off.
A warning may be transmitted if a
direction marking (e.g. arrow) or
non-standard marking (e.g. graffi ti)
is crossed. Operating fault
In the event of a malfunction, the
service warning lamp comes on,
accompanied by an audible signal
and a message on the multifunction
screen.
Consult a CITROËN dealer.
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver. The detection may be impeded:
- if the sensors are dirty (mud,
snow...),
- if the markings on the ground are worn,
- if there is little contrast between the markings on the ground and
the road surface.

VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located behind
the vehicle, however, it will not be
able to detect obstacles located im-
mediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking assistance is
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward
gear,
- when the vehicle has been sta- tionary for more than three sec-
onds in forward gear.
The parking assistance system
cannot, in any circumstances, re-
place the need for vigilance and
responsibility on the part of the
driver.
The parking assistance is
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicated
by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately thirty centimetres, the
audible signal becomes continuous
and/or the "Danger" symbol appears,
depending on the multifunction screen
version.

122
D R I V I N G
In bad weather or in winter, ensure
that the sensors are not covered
with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that
the sensors may be dirty.
When the vehicle is being driven
at a speed below approximately
6 mph (10 km/h), certain sourc-
es of noise (motorcycles, lorries,
pneumatic drills, ...) may trigger the
reversing audible signal.
Reactivation

 Press button A again, the warning
lamp switches off, the system is
reactivated.
Deactivation Operating fault
If an operating fault occurs, this warn-
ing lamp is displayed on the instrument
panel and/or a message appears on
the multifunction screen, accompa-
nied by an audible signal (short beep),
when reverse gear is engaged.
Consult a CITROËN dealer.

 Press button A , the warning lamp
comes on, the system is fully de-
activated.
The system will be deactivated au-
tomatically when a trailer is being
towed or when a bicycle carrier is
fi tted (vehicle fi tted with a towbar
or bicycle carrier recommended by
CITROËN).
