PARKING SPACE SENSORS
After measuring the parking space
available between two vehicles or
obstacles, this system gives you in-
formation on:
- the possibility of fi tting into a free
space, depending on the dimen-
sions of your vehicle and the dis-
tances needed for manoeuvring,
- the level of diffi culty of the ma-
noeuvre to be performed.
The system does not measure spaces
which are clearly much smaller or
larger than the size of the vehicle.
Displays in the instrument
panel
The parking space sensor
function warning lamp can
have three different states:
- off:
the function is not selected,
- on fi xed:
the function is selected
but the conditions for measure-
ment are not yet met (direction
indicator not operating, speed
too high) or the measurement
phase has ended,
- fl ashing:
measurement is in
progress or the message is be-
ing displayed. You can activate the "parking space
sensor" function by pressing but-
ton A. The fi xed illumination of the
warning lamp indicates that the
function is selected.

Operation
You have identifi ed a parking
space:
)
Press button A
to activate the
function.
)
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-
proximately 20 km/h), to prepare
for your manoeuvre.
The system then measures the
size of the space.
)
The system informs you of the
level of diffi culty of the manoeu-
vre via a message in the multi-
function screen accompanied by
an audible signal.
Parking possible
Parking diffi cult
Parking not advised
The function displays the following
types of message: The function deactivates itself auto-
matically:
- when you engage reverse gear,
- when you switch off the ignition,
- fi ve minutes after activation of
the function or after the last mea-
surement operation,
- if the vehicle speed exceeds the
threshold of 45 mph (approxi-
mately 70 km/h) for one minute.
If there is a malfunction,
have the system checked
by a CITROËN dealer or a
qualifi ed workshop.
If the lateral distance between your
vehicle and the parking space is too
great, the system may not operate.
- The function remains available
after each measurement and so
can measure a number of places
successively.
- In bad weather or in winter, ensure
that the sensors are not covered
by dirt, or by ice or snow.
- The parking space sensor func-
tion deactivates the front parking
sensors during the space mea-
suring phase when you are in
forward gear.

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 bum-
per, trigger a warning if the vehicle
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 this button, the indicator
lamp comes on.
Deactivation
)
Press this button again, the indi-
cator lamp goes 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 marking
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, ac-
companied by an audible signal and
a message in the screen.
Contact a CITROËN dealer or a
qualifi ed workshop.
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.

DRIVING
PARKING SENSORS
This system indicates the proximity
of an obstacle (person, vehicle, tree,
gate, etc.) which comes within the
fi eld of detection of sensors located
in the bumper.
Certain types of obstacle (stake,
roadworks cone, etc.) detected ini-
tially will no longer be detected at
the end of the manoeuvre due to the
presence of blind spots.
Visual assistance
This supplements the audible signal
by displaying bars in the multifunc-
tion screen which move progressively
nearer to the vehicle. When the ob-
stacle is near, the "Danger" symbol is
also displayed in the screen.
Audible assistance
The proximity information is given
by an intermittent audible signal, the
frequency of which increases as the
vehicle approaches the obstacle.
The sound emitted by the speaker
(right or left) indicates the side on
which the obstacle is located.
When the distance between the
vehicle and the obstacle becomes
less than approximately thirty centi-
metres, the audible signal becomes
continuous.
This function cannot, in any circum-
stances, take the place of the vigi-
lance and responsibility of the driver.
Rear parking sensors
The system is switched on by engag-
ing reverse gear. This is accompanied
by an audible signal.
The system is switched off when you
exit reverse gear.

DRIVING
Front parking sensors
In addition to the rear parking sensors,
the front parking sensors are triggered
when an obstacle is detected in front
and the speed of the vehicle is still be-
low 6 mph (10 km/h).
The front parking sensors are inter-
rupted if the vehicle stops for more
than three seconds in forward gear,
if no further obstacles are detected
or when the speed of the vehicle ex-
ceeds 6 mph (10 km/h).
The sound emitted by the speaker
(front or rear) indicates whether the
obstacle is in front or behind.
Deactivation/Activation of the
front and rear parking sensors
The function is deactivated by press-
ing this button. The indicator lamp in
the button comes on.
Pressing this button again reacti-
vates the function. The indicator
lamp in the button goes off.
The function will be deactivated au-
tomatically if a trailer is being towed
or a bicycle carrier is fi tted (vehicle
fi tted with a towbar or bicycle car-
rier recommended by CITROËN).
Operating fault
In the event of a malfunction
of the system, when reverse
gear is engaged this warn-
ing lamp is displayed in the
instrument panel and/or a message
appears in the screen, accompanied
by an audible signal (short beep).
Contact a CITROËN dealer or a
qualifi ed workshop.
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 moving at a
speed below 6 mph (10 km/h), cer-
tain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trig-
ger the audible signals of the parking
sensor system.

PRACTICAL INFORMATION
Wheel for temporary use
If your vehicle is equipped with a
spare wheel for temporary use only,
when fi tting this it is normal to observe
that the wheel bolts do not come to
bear directly on the wheel rim.
The spare wheel is secured by the
conical section of each wheel bolt.
When refi tting the original wheel, en-
sure that the wheel bolts and wash-
ers are clean and in good condition.
Fitting a wheel
)
Position the wheel with the aid of
the centring guide 3
.
)
Do up the 3 bolts by hand, then
remove the centring guide 3
.
Position the 4
th bolt.
)
Pre-tighten the wheel bolts, us-
ing the wheelbrace 4
.
)
Retract the jack 5
and disengage
it.
)
Tighten the wheel bolts, using
the wheelbrace 4
.
)
Ensure that the tyre pressure is
correct.
Under-infl ation detection
These wheels have tyre pressure
sensors. It is essential to have repairs
carried out by a CITROËN dealer or a
qualifi ed workshop. The spare wheel
does not have a sensor.
Security bolts (alloy wheels)
Each wheel may be equipped with
one security bolt (depending on
country of sale).
To remove it:
)
remove the protector that is cov-
ering it by means of the tool for
removing the chrome covers 2
.
)
use the security bolt socket 6
with the wheelbrace 4
.
Dimension of the spare
wheel
If your spare wheel has dimensions
different from those of the normal ve-
hicle wheels (identifi ed by a label),
you must use the spare wheel only
temporarily, drive with caution, not
exceed 50 mph (80 km/h) and have
the tyre repaired and the normal
wheel refi tted as soon as possible.
Tyre pressures
These are indicated on the label
on the right-hand front door pil-
lar (see section "Technical Data -
§ Identifi cation markings").
The wheel bolts are specifi c
to each type of wheel.
If new wheels are fi tted,
check with your CITROËN dealer
or a qualifi ed workshop that the
wheel bolts are compatible with the
new wheels.
Note: make a note of the code
number on the head of the security
bolt socket. This will enable you to
obtain a replacement security bolt
socket from a CITROËN dealership.
