VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING SENSORS
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located behind
the vehicle, however, it will not be
able to detect obstacles located im-
mediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking sensors are
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward gear,
- when the vehicle has been station- ary for more than three seconds in
forward gear.
The parking sensor system cannot,
in any circumstances, replace the
need for vigilance and responsibility
on the part of the driver.
The parking sensors are
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and display of the vehicle on
the multifunction screen.
The proximity information is indica-
ted by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately thirty centimetres, the
audible signal becomes continuous
and/or the "Danger" symbol appears,
depending on the multifunction screen
version.

D R I V I N G
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 being driven
at a speed below approximately
6 mph (10 km/h), certain sourc-
es of noise (motorcycles, lorries,
pneumatic drills, ...) may trigger the
parking sensor audible signals.
Reactivation

 Press button A again, the warning
lamp switches off, the system is
reactivated.
Deactivation Operating fault
If an operating fault occurs, this warn-
ing lamp is displayed on the instrument
panel and/or a message appears on
the multifunction screen, accompa-
nied by an audible signal (short beep),
when reverse gear is engaged.
Consult a CITROËN dealer.

 Press button A , the warning lamp
comes on, the system is fully de-
activated.
The system will be deactivated au-
tomatically when a trailer is being
towed or when a bicycle carrier is
fi tted (vehicle fi tted with a towbar
or bicycle carrier recommended by
CITROËN).

TOWING A TRAILER,A CARAVAN, ETC.
Towbar suitable for the attachment
of a trailer or caravan 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. If the trailer is not fi tted by
a CITROËN dealer, it is im-
perative that it is fi tted us-
ing the electrical pre-equipment
installed at the rear of the vehicle,
in accordance with the manufactur-
er'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
towing load must be reduced by 10 %
and so on for every 1 000 metres of
altitude.
Refer to the "Technical Data" section
for details of the weights and towing
loads which apply to your vehicle.
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 towing load on a long
slope depends on the gradient and
the ambient temperature.
In all cases, pay attention to 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 braking
distance.
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 de-
activated automatically if a genuine
CITROËN towbar is used.
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. Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be particu-
larly careful.
