system is an aid to driving which
does not replace the need for the
driver to be vigilant or to drive
responsibly. Puncture
The service warning light
comes on on the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The STOP warning light
comes on on the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
display locating the wheel
concerned
.
Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes
.
Change the damaged wheel (punctured

pressure checked as soon as possible

Sensor(s) not detected or faulty
The service warning light
comes on on the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display locating
the wheel or wheels which are not
detected or indicating a fault in the
system.
Have the faulty sensor(s) checked
by a CITROËN dealer. All repairs and changing of tyres
o n a w h e e l fi t t e d w i t h t h i s s y s t e m
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you
install a wheel which is not detect-
e d b y y o u r v e h i c l e ( e x a m p l e : fi t t i n g
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not eliminate
the need to have the tyre pres-
sure checked regularly (refer to the
" T e c h n i c a l d a t a - § I d e n t i fi c a t i o n
features" section) to ensure that the
optimum dynamic performance of
the vehicle is maintained and pre-
vent premature wear of the tyres,
particularly in arduous driving con-
ditions (heavy load, high speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.

PARKING SPACE SENSOR
System which measures the parking
space available between two vehicles
or obstacles. It measures the size of the
space and gives you information on:
- t h e p o s s i b i l i t y o f fi t t i n g i n t o a free space, depending on the
dimensions of your vehicle and
the distances necessary for your
manoeuvring,
- t h e l e v e l o f d i f fi c u l t y o f t h e m a - noeuvre to be performed.
The system does not measure spac-
es which are clearly much smaller or
larger than the size of the vehicle. Displays on the instrument
panel
The parking space sensor
function warning lamp can
have three different statuses:
- off: the function is not selected,
- o n fi x e d : the function is selected
but the conditions for measuring
are not yet met (direction indi-
cator not operating, speed too
high) or the measuring phase is
terminated.
- fl a s h i n g : the measuring is in
progress or the message is being
displayed. You can select the "parking space
sensor" function by pressing button
A . T h e fi x e d l i g h t i n g o f t h e w a r n i n g
lamp indicates that the function is
selected.

Operation
Y o u h a v e i d e n t i fi e d a p a r k i n g s p a c e :
Press button A to select the function.
Activate the direction indicator
on the side where the space is to
be measured.
During the measuring, go
forward the length of the space,
at a speed less than 12 mph
(approx. 20 km/h), to prepare for
your manoeuvre.
The system then measures the size of the space.
The system informs you of the
l e v e l o f d i f fi c u l t y o f t h e m a n o e u v r e
via a message on the multifunction
screen accompanied by a gong.
Depending on the message is-
sued by the system, you may or
may not be able to perform the
manoeuvre. Parking possible
P a r k i n g d i f fi c u l t
Parking not advised
The function displays the following
types of message: The function deselects itself auto-
matically:
- when you engage reverse gear,
- when you switch off the ignition,
- if measuring is not requested,
- w i t h i n fi v e m i n u t e s o f s e l e c t i o n o f
the function,
- if the vehicle speed exceeds the threshold of 45 mph (approx.
70 km/h) for one minute.
If there is a malfunction,
have the system checked
by a CITROËN dealer.
If the lateral distance between your
vehicle and the parking space is too
large, the system may not be able to
measure the space.
- The function remains available
after each measurement and
thus can measure more than
one space during your search.
- In bad weather conditions or in winter, make sure that the sensors
are not covered by dirt, or by ice or
snow.
- The parking space sensor function deactivates the front
parking assistance during the
space measuring phase when
you are in forward gear.

LANE DEPARTURE WARNING SYSTEM
System which detects the involun-
t a r y c r o s s i n g o f l o n g i t u d i n a l t r a f fi c
lane markings on the ground (con-
tinuous or discontinuous line).
S e n s o r s , fi t t e d b e l o w t h e f r o n t
bumper, trigger a warning if the vehi-
cle drifts (speed higher than 50 mph
(80 km/h)).
This system operates to its full
potential above all when used on
motorways and main roads. Activation
Press button A , the indicator light
comes on.
Deactivation
Press button A again, the indica-
tor light 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 (arrow) or
n o n - s t a n d a r d m a r k i n g ( g r a f fi t i ) i s
crossed. Operating fault
In the event of a malfunction, the
service warning light comes on, ac-
companied by an audible signal and a
message on the multifunction display.
Consult a CITROËN dealer.
The lane departure warning system
cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the driver. The detection may be disrupted:
- 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,
vehicle, tree, barrier...) located
behind the vehicle, however, it will
not be able to detect obstacles
located immediately 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 stationary for more than three
seconds 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 display.
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 display, 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
a p p r o x i m a t e l y t w e n t y - fi v e c e n t i m e -
tres, the audible signal becomes
continuous and/or the "Danger"
symbol appears, depending on the
multifunction display version.
