system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen 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 lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
screen locating the wheel
concerned.
Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes.
Change the damaged wheel (punctured
o r v e r y d e fl a t e d t y r e ) , a n d h a v e t h e t y r e
pressure checked as soon as possible.
Sensor(s) not detected or faulty
The service warning
lamp comes on in the
instrument panel, ac-
companied by an audible
signal and a message on
the multifunction screen
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 in-
stall a wheel which is not detected
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 perform-
ance of the vehicle is maintained
and prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (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 vehi-
cles or obstacles. It measures the
size of the space and gives you in-
f o r m a t i o n o n :
- 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 f r e e 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

- 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 be-
ing displayed. You can select the "parking space

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 func-
tion.
Activate the direction indicator
on the side where the space is to
be measured.
During the measuring, go for-
ward the length of the space, at
a speed less than 12 mph (ap-
prox. 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 -
vre via a message on the multi-
function 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.

P a r k i n g d i f fi c u l t
Parking not advised
The function displays the following
t y p e s o f m e s s a g e : The function deselects itself auto-
m a t i c a l l y :
- 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 sen-
sors are not covered by dirt, or
by ice or snow.
- The parking space sensor func- tion deactivates the front park-
ing assistance during the space
measuring phase when you are
in forward gear.

t h e d r i v e r ' s s e a t c u s h i o n :
- 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
n o n - s t a n d a r d m a r k i n g ( e . g . g r a f fi t i )
is crossed. Operating fault
In the event of a malfunction, the
service warning lamp comes on, ac-
companied by an audible signal and a
message on the multifunction screen.
Consult a CITROËN dealer.

cannot, in any circumstances, re-
place the need for vigilance and re-
sponsibility on the part of the driver. T h e d e t e c t i o n m a y b e i m p e d e d :
- 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.
