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, en-
sure that the sensors are not cov-
ered 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.

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 progressive-
ly nearer to the vehicle. When the
obstacle is near, the "Danger" sym-
bol 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 en-
gaging reverse gear. This is accom-
panied by an audible signal.
The system is switched off when you
exit reverse gear.

Front parking sensors

In addition to the rear parking sen-
sors, the front parking sensors are
triggered when an obstacle is detect-
ed in front and the speed of the ve-
hicle is still below 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 park-
ing sensor system.

PRACTICAL INFORMATION

Towbar suitable for the attachment
of a trailer 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.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to
a CITROËN dealer or a qualifi ed
workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with the
vehicle manufacturer's instructions.

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 ex-
ceeding 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.
Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


)
To lower the engine speed, re-
duce your speed.
The maximum towed load on a long
incline depends on the gradient and
the ambient temperature.
In all cases, keep a check on the
coolant 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 brak-
ing distance.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

Tyres


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


Lighting


)
Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.
Driving with a trailer places greater
demands on the towing vehicle and
the driver must take particular care.

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 avoid any risk of jamming of
the pedals:

tioned and secured correctly,

- never fi t one mat on top of an-
other.
