TECHNOLOGY on BOARD
Parking sensors
AUDIBLE REAR PARKING SENSORS
If fitted on your vehicle, the system consists
of four proximity sensors, installed in the
rear bumper.
They detect any obstacle: person, vehicle,
tree, fence, behind the vehicle during the
manoeuvre.
However, objects the size or thickness of
which are detected at the beginning of the
manoeuvre will no longer be detected at the
end of the manoeuvre: blind spots between
and below the sensors. Examples: stake,
roadworks cone or pavement post.
The rear parking sensor system may be
coupled with a reversing camera. Operation
Engage reverse gear with the gear lever.
The proximity information is indicated by an
audible signal of increasing frequency as the
vehicle approaches the obstacle.
When the distance between the rear of
the vehicle and the obstacle is less than
approximately thirty centimetres, the audible
signal becomes continuous.
The system cannot, in any circumstances,
take the place of the vigilance and
responsibility of the driver.
Switching off
Come our of reverse gear into neutral.
Operating fault
If this warning lamp comes
on in the instrument panel
accompanied by a message in
the screen, contact a CITROËN
dealer or a qualified workshop.
Good practice
In bad weather or in winter, ensure that the
sensors are not covered with mud, ice or
snow.

Parking sensors
REVERSING CAMERA
If your vehicle is fitted with this camera, it is
located at the rear, next to the third brake
lamp.
It sends views to the screen installed
in the cab. This rear vision is an aid to
manoeuvring.
The reversing camera may be coupled with
rear parking sensors. Screen
The camera sends the images to a 5 inch
LCD colour screen. This screen is also
the one used by the touch screen audio-
telematic system.
Activation and deactivation of the system
is done in the settings menu of the touch
screen audio-telematic system.
Operation
The camera comes into operation when
reverse gear is engaged and remains active
up to approximately 9 mph (15 km/h). It is
deactivated above 11 mph (18 km/h).
The camera also comes on, with the vehicle
stationary, when the rear doors are opened.
Switching off
When a forward gear is engaged, the last
image remains displayed for approximately
5 seconds then switches off.
In the same way, the last image also
remains displayed, with the vehicle
stationary, when the rear doors are closed.
Good practice
With optimum vehicle conditions (position on
the road, loading level) the maximum area of
visibility covered by the camera has a fi eld
depth approximately 3 m long and 5.5 m wide.
The area of visibility may vary depending on
the external weather conditions (brightness,
rain, snow, fog, ...), the load in the vehicle
and the position of the vehicle on the road.
When cleaning the camera and the screen,
avoid using a detergent or a tool which may
scratch the glass.
Use a non-abrasive cloth or a small brush.

Transport solutions
ACCESSORIES
Distribution of loads: distribute the load in
the trailer so that the heaviest objects are as
close as possible to the axle and the nose
weight is close to the maximum authorised
without, however, exceeding it.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.
Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature. Tyres: check the tyre pressures of the
towing vehicle and of the trailer, observing
the recommended pressures.
Fitting a towbar
We recommend the use of genuine
CITROËN towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle and that
the fitting of this equipment is entrusted to a
CITROËN dealer.
These genuine towbars are compatible with
the operation of the rear parking sensors
and the reversing camera, if fitted to your
vehicle.
If this equipment is not fitted by a CITROËN
dealer, it must be fitted in line with the
manufacturer's instructions.
Good practice
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
Refer to the "Checks - Levels and
checks" section.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually. Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
ABS: the system only controls the vehicle,
not the trailer.
Rear parking sensors: the system does not
operate while the vehicle is towing.
Refer to the "Technical data -
Identification markings" section.

Installation of radiocommunication
transmitters

You are advised to contact a CITROËN
dealer before installing accessory
radiocommunication transmitters with
external aerial on your vehicle.
CITROËN dealers can advise you on
the specifications (frequency waveband,
maximum output power, aerial position,
specific installation conditions) of the
transmitters which can be fitted, in
accordance with the Vehicle Electromagnetic
Compatibility Directive (2004/104/EC).
The fitting of electrical equipment or
accessories which are not listed by
CITROËN may result in the failure of your
vehicle's electronic system.
We request that you take note of this point
and recommend that you contact a dealer
to be shown the range of recommended
equipment and accessories.
Depending on the country in which the
vehicle is sold or operated, it may be
compulsory to have a high visibility vest,
warning triangle, replacement bulbs and
breathalyzer in the vehicle.
To prevent the mat from becoming caught
under the pedals:
- ensure that the mat and its fixings are
positioned correctly,
- never fit one mat on top of another.

Levels and checks

The presence of this label, in particular
with the Stop & Start system, indicates the
use of a specific 12 V lead-acid battery
with special technology and specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery. These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
maintenance and warranty guide included in
the handbook pack.
CHECKS
Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
Bleeding water from the Diesel filter
If this warning lamp comes on,
bleed the filter, or bleed regularly
each time the engine oil is
changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
Air filter and passenger compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are given in
the maintenance and warranty guide.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.
Refer to the "Checks - Under the
bonnet" section.
HDi engines use advanced technology.
All work requires a special qualification
which is guaranteed by a CITROËN dealer
or a qualified workshop.
