PARKING SPACE SENSORS
System which measures the parking
space available between two vehicles
or obstacles. It measures the size of the
space and gives you information on:
- the possibility of fi tting into a free
space, depending on the dimensions
of your vehicle and the distances
needed for manoeuvring,
- the level of diffi culty of the manoeuvre
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
- on fi xed:
the function is selected by
a press on control A
.
- off:
the function is not selected,
The parking space sensor
function warning lamp can
have two different states:
Operation
You have identifi ed a parking space:
)
Press button A
to select the function.
)
Operate the direction indicator on
the side where the space is to be
measured; a message is displayed
to confi rm that measurement is in
progress.
)
During measurement, go forward
the length of the space, at a speed
less than 12 mph (approx. 20 km/h),
to prepare for your manoeuvre.
)
Once the measurement has been
completed, the system informs you
of the level of diffi culty of the ma-
noeuvre by a message in the multi-
function screen accompanied by an
audible signal.

The function displays the following types
of message:
Parking possible
Parking diffi cult
Parking not advised
The function deselects itself automati-
cally:
- when you engage reverse gear,
- when you switch off the ignition,
- if measuring is not requested,
- within fi ve minutes of selection of
the function,
- if the vehicle speed exceeds the
threshold of 45 mph (approx. 70 km/h)
for one minute.
If the lateral distance between your ve-
hicle and the parking space is too large,
the system may not be able to measure
the space.
If there is a fault, have the sys-
tem checked by a CITROËN
dealer or a qualifi ed workshop.
The system remains available after
each measurement and can therefore
measure several spaces in succession.
In poor or wintry weather, ensure that
the sensors are free of dirt, ice or
snow.
The parking space sensor system de-
activates the front parking sensors
when measuring forwards.

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, road-
works cone, etc.) detected initially will
no longer be detected at the end of the
manoeuvre due to the presence of blind
spots.
This function cannot, in any cir-
cumstances, take the place of
the vigilance and responsibility
of the driver.
The system is switched on by engaging
reverse gear. This is accompanied by
an audible signal.
The system is switched off when you
exit reverse gear.
Rear parking sensors
Audible assistance
The proximity information is given by an
intermittent audible signal, the frequen-
cy of which increases as the vehicle ap-
proaches 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 centimetres, the
audible signal becomes continuous.
Visual assistance
This supplements the audible signal
by displaying bars in the multifunction
screen which move progressively near-
er to the vehicle. When the obstacle is
near, the "Danger" symbol is also dis-
played in the screen.

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 below
6 mph (10 km/h).
The front parking sensors are interrupted
if the vehicle stops for more than three
seconds in forward gear, if no further ob-
stacles are detected or 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 function. The indicator lamp in the
button goes off.
Operating fault
The function will be deactivated
automatically if a trailer is being
towed or a bicycle carrier is fi t-
ted (vehicle fi tted with a towbar
or bicycle carrier recommended
by CITROËN).
In bad weather or in winter, en-
sure that the sensors are not
covered with mud, ice or snow.
When reverse gear is engaged,
an audible signal (long beep) in-
dicates that the sensors may be
dirty.
When the vehicle is moving at a
speed below 6 mph (10 km/h),
certain sound sources (motor-
cycle, lorry, pneumatic drill, etc.)
may trigger the audible signals
of the parking sensor system.
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.
The sound emitted by the speaker (front
or rear) indicates whether the obstacle
is in front or behind.

Manual gearbox
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the servicing book-
let for the details of the level
checking interval for this com-
ponent.
6-speed electronic gearbox
system
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the servicing booklet
for details of the checking in-
terval for this component.
Automatic gearbox
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the servicing booklet
for details of the level checking
interval for this component.
Electric parking brake
This system does not require any
routine servicing. However, in
the event of a problem, have the
system checked by a CITROËN
dealer or a qualifi ed workshop.
For more information, see "Driving - Electric parking brake - § Operating faults".
Brake pads
Brake disc wear
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer or a quali-
fi ed workshop.
Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.
In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.
Manual parking brake
For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop. Brake wear depends on the
style of driving, particularly in
the case of vehicles used in
town, over short distances. It
may be necessary to have the
condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the system, a drop
in the brake fl uid level indicates that the
brake pads are worn.

lamps in the instrument panel
are on (not fl ashing).
The occupants must get out of
the vehicle and wait where they
are safe.
If necessary, place a chock under
the wheel diagonally opposite the
wheel to be changed.
Never go underneath a vehicle
raised using a jack; use an axle
stand.
*
position R
