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 displayed
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.
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 quali-
fi ed workshop.

The sound emitted by the speaker (front
or rear) indicates whether the obstacle
is in front or behind.

Access to the spare wheel

The spare wheel is installed in the boot
under the fl oor.
Depending on version, the spare wheel
may be a standard size steel or alloy
wheel, or for some countries it is the
"space saver" type.
For access to the spare wheel, refer to
the paragraph "Access to the tools" on
the previous page.
Putting the standard wheel back in
place



Put the wheel back in its housing.


Unscrew the yellow central bolt by a
few turns then put it in place in the
centre of the wheel.


Tighten fully until the central bolt
clicks to retain the wheel correctly.

Tyre under-infl ation detection
The spare wheel is not fi tted with
a sensor. The punctured wheel
must be repaired by a CITROËN
dealer or aqualifi ed workshop.

Taking out the standard wheel



Unscrew the yellow central bolt.


Raise the spare wheel towards you
from the rear.


Take the wheel out of the boot.



Put the box back in place in the cen-
tre of the wheel and clip it.


If your vehicle has an electric
parking brake, only a space sav-
er wheel can be stowed in the
boot.


Introduce a fl at screwdriver in the
hole in the fi nisher.


Pull and lever to unclip the bumper
fi nisher (the parking sensor stays
with the fi nisher).


Remove the two module fi xing screws
and remove it from its housing.


Disconnect the bulb holder connector.


Turn the bulb holder a quarter of a
turn and extract it.


Pull the bulb and change it.
To r efi t, carry out these operations in
reverse order.
To replace these bulbs you may also
contact a CITROËN dealer or a qualifi ed
workshop.







Changing foglamp bulbs







Changing the side spotlamps
For the replacement of this type of LED
lamp, contact a CITROËN dealer or a
qualifi ed workshop.









Changing integrated direction
indicator side repeaters



Insert a screwdriver towards the
centre of the repeater between the
repeater and the base of the mirror.


Tilt the screwdriver to extract the re-
peater and remove it.


Disconnect the repeater connector.
To reassemble, carry out these operations
in reverse order.
Contact a CITROËN dealer or a qualifi ed
workshop to obtain replacement repeaters.

TOWING A TRAILER


We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions.
The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or installation of a bicycle carrier,
with additional lighting and signalling.

Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer.
Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.



Driving advice


Distribution of loads



Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude.

Side wind



Take into account the increased
sensitivity to side wind.


Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.



To lower the engine speed, reduce
your speed. The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant temperature.



If the warning lamp and the
STOP
warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.


Braking
Towing a trailer increases the braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres




Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.



Lighting



Check the electrical lighting and sig-
nalling on the trailer.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
