Tyre under-inflation detection
System which automatically checks the p
ressures of the tyres while driving.
The
system continuously monitors the
p
ressures of the four tyres, as soon as the
vehicle
is moving.
A
pressure sensor is located in the valve of
e
ach tyre (except the spare wheel).
The
system triggers an alert if a drop in
p
ressure is detected in one or more tyres.
The
tyre under-inflation detection system is an
a
id to driving which does not replace the need
f
or vigilance on the part of the driver.This
system does not avoid the need
t
o check the tyre pressures regularly
(
including the spare wheel) and before
a
long journey.
Driving with under-inflated tyres
a
dversely affects road holding,
e
xtends braking distances and causes
p
remature tyre wear, particularly under a
rduous conditions (vehicle loaded, h
igh speed, long journey).The tyre pressures for your vehicle can
be
found on the tyre pressure label (see
t
he "Identification markings" section).
The tyre pressures must be checked
w
hen the tyres cold (vehicle stopped
f
or 1 hour or after driving for less then
6
miles (10 km) at moderate speed).
O
ther wise, add 0.3 bar to the values i
ndicated on the label.
Driving with under-inflated tyres
i
ncreases fuel consumption.

The flashing and then fixed illumination of the under-inflation w
arning lamp accompanied by the
i
llumination of the service warning
l
amp indicates a fault with the system.
Operating fault
The aler t is given by the fixed illumination o
f this warning lamp, accompanied by a
n audible signal, and depending on
e
quipment, the display of a message.
Under-inflation alert
In the event of a problem on one of the tyres, the symbol or the message appears, according
t
o equipment, to identify it.
F
R
educe speed, avoid sudden steering
m
ovements or harsh brake applications.
F
S
top as soon as it is safe to do so. In
this case, monitoring of the tyre pressures is
n
ot assured.
F
I
f you have a compressor (the one in the
t
emporary puncture repair kit for example),
c
heck the four tyre pressures when cold.
I
f it is not possible to check the tyre
p
ressures at the time, drive carefully at
r
educed
s
peed.
or
F
I
n the event of a puncture, use the
temporary puncture repair kit or the spare
w
heel (according to equipment).
Go to a CITROËN dealer or a qualified w
orkshop to have the system checked or,
f
ollowing the repair of a puncture, to have the
o
riginal wheel, equipped with a sensor, refitted.
Any
tyre repair or replacement on a wheel
f
itted with this system must be carried out by a
C
ITROËN dealer or a qualified workshop.
If
after changing a tyre, a wheel is not detected
b
y your vehicle (fitting snow tyres for example),
y
ou must have the system reinitialised by a
C
ITROËN dealer or a qualified workshop.
The
loss of pressure detected does not
a
lways lead to visible deformation of the
t
yre. Do not rely on just a visual check.This
alert is also displayed when one or
m
ore wheels is not fitted with a sensor
(
for example, a space-saver or steel
spar
e
w
heel).
The alert is maintained until the tyre or t
yres concerned is reinflated, repaired
o
r replaced.
The
spare wheel (space-saver type or a
s
teel rim) does not have a sensor.

Blind spot sensors
This driving assistance system warns the driver of the presence of another vehicle in the blind
s
pot angle of their vehicle (areas masked from
t
he driver's field of vision), as soon as this
p
resents a potential danger.
Operation
F On switching on the ignition, or engine r
unning, press this button to activate the
f
unction; the warning lamp comes on.
Sensors
fitted in the front and rear bumpers
m
onitor the blind spots.
A
warning
lamp
appears
in
the
door
mirror
on

mmediately,
when
being
overtaken,
-
a
fter
a
delay
of
about
one
second,
when
ov
ertaking
a
vehicle
slowly.
This
system
is
designed
to
improve
s
afety
when
driving
and
is
in
no
c
ircumstances
a
substitute
for
the
use
o
f
the
interior
rear
view
mirror
and
door

irrors.
It
is
the
driver's
responsibility
to
c
onstantly
check
the
traffic,
to
assess
t
he
distances
and
relative
speeds
o
f
other
vehicles
and
to
predict
their
m
ovements
before
deciding
whether
to

F To deactivate the system, press this button a
gain; the warning lamp goes off.
The
state of the system remains in memory on
s
witching off the ignition.
Operating fault
The system is automatically deactivated when towing with a towbar approved by
CIT
ROËN. The
system may suffer temporary
i
nterference in certain weather
conditions (rain, hail...).
In particular, driving on a wet sur face
o
r moving from a dry area to a wet area
c
an cause false alerts (for example, the
p
resence of a fog of water droplets in
t
he blind spot angle is interpreted as a
v
ehicle).
In bad or wintry weather, ensure that
t
he sensors are not covered by mud, ice
o
r snow.
Take care not to cover the warning zone
i
n the door mirrors or the detection
z
ones on the front and rear bumpers
w
ith adhesive labels or other objects;
t
hey may hamper the correct operation o
f the system.
In the event of a fault, the warning lamp in the
b
utton flashes then goes off.
Have it checked by a CITROËN dealer or a
q
ualified
w
orkshop.

Parking sensors
The system is switched on by engaging reverse gear. This is accompanied by an audible signal.
The
system is switched off when you come out
o
f reverse gear.
Rear parking sensors
Audible assistance
The proximity information is given by an intermittent audible signal, the frequency of which i
ncreases as the vehicle approaches the obstacle.
The
sound emitted by the speaker (right or left)
i
ndicates the side on which the obstacle is located.
When
the distance between the vehicle and
t
he obstacle becomes less than approximately
t
hirty centimetres, the audible signal becomes
c
ontinuous.
Visual assistance
This supplements the audible signal by d isplaying bars in the multifunction screen
w
hich move progressively nearer to the vehicle.
W
hen the obstacle is near, the "Danger"
s
ymbol is displayed in the screen.
This function cannot, in an y c ircumstances, t
ake the place of the vigilance of the driver.
This system indicates the proximity of an obstacle (person, vehicle, tree, gate, etc.) which c
omes within the field of detection of sensors
l
ocated in the bumper.
Certain
types of obstacle (stake, roadworks
c
one, etc.) detected initially will no longer be
d
etected at the end of the manoeuvre due to
t
he presence of blind spots.

In addition to the rear parking sensors, the front parking sensors are triggered when an obstacle i
s detected in front and the speed of the vehicle is
s
till below 6 mph (10 km/h).
The
front parking sensors are interrupted if the
v
ehicle stops for more than three seconds in
f
or ward gear, if no further obstacles are detected
o
r when the speed of the vehicle exceeds 6 mph
(
10 km/h).
Front parking sensors
Deactivation/Activation of the
front and rear parking sensors
The function is deactivated by pressing this button. The indicator lamp in the button
comes
on.
Pressing
this button again reactivates the
f
unction. The indicator lamp in the button
goes
off.
Operating fault
In the event of a malfunction of the system, when reverse gear
i
s engaged this warning lamp is
d
isplayed in the instrument panel
a
nd/or a message appears in the
s
creen, accompanied by an audible
s
ignal (short beep).
Contact
a CITROËN dealer or a
q
ualified
w
orkshop.
The
sound
emitted
by
the
speaker
(front
or
r
ear)
indicates
whether
the
obstacle
is
in
front
o
r
behind. The
function
will
be
deactivated
a
utomatically
if
a
trailer
is
being
towed
o
r
a
bicycle
carrier
is
fitted
(vehicle
f
itted
with
a
towbar
or
bicycle
carrier
r
ecommended
by
CITROËN). In
bad weather or in winter, ensure
t
hat
the sensors are not covered with
m
ud,
ice or snow. When reverse gear is
e
ngaged, an audible signal (long beep)
i
ndicates that the sensors may be dirty.
Certain
sound sources (motorcycle,
l
orry,
pneumatic drill, etc.) may trigger
t
he
audible signals of the parking
s
ensor system.
