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.

ROOF CARRYING SYSTEMS
Refer to the "Technical data -
"Dimensions" section for more
information on the length (L1 to L4) and the
height (H1 to H3) of the vehicle. Maximum load on the roof, evenly
distributed: 150 kg, for all versions,
within the vehicle's weight limit (Gross
Vehicle Weight).
For reasons of safety and to avoid damaging
the roof, it is essential to use a carrying
system (roof bars or roof rack) that is
approved for your vehicle.
Roof bars can only be fitted to H1 height
van, combi and minibus versions. On a
minibus, check for the presence of roof air
conditioning units.
TOWBAR WITH QUICKLY
DETACHABLE TOW BALL
This tow ball can be fitted and removed
quickly and easily without the use of tools.
When not towing a trailer, remove the
quickly-detachable tow ball before driving. Never exceed the maximum authorised
weight for the vehicle plus trailer
(Gross Train Weight - GTW).
For information on the maximum
trailer weight and the recommended
nose weight, refer to the "Technical data -
Weights" section. The carrying system must always be
secured to the fitting points provided on the
vehicle's roof: 6, 8 or 10, depending on the
wheelbase of the vehicle.
Observe the instructions for fitting and use
provided with the carrying system.
Observe in full the legal requirements
related to carrying outsized loads.

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.

Levels and checks
Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust / particle filter system.
Have the whole system checked by a
CITROËN dealer or a qualified workshop.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
Saturation / Regeneration Because of the higher exhaust
gas temperature resulting from the
normal operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles, ...) so as to avoid
any risk of fire.
Particle filter system (Diesel)
An addition to the catalytic converter, this
filter makes an active contribution to the
preservation of air quality by the retaining
of the unburnt pollutant particles. Black
exhaust fumes are thus no longer emitted.
Operation
This filter, fitted to the exhaust system,
accumulates particles of soot. The engine
management unit controls the automatic
periodic elimination of the soot particles
(regeneration).
The regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions
of the vehicle. During this phase, you
may notice some unusual phenomena -
increased idling speed, cooling fan running,
increase in smoke and higher exhaust gas
temperature - which does not affect the
operation of the vehicle or the environment. After prolonged idling or driving at very
low speeds, you may occasionally
notice water vapour being emitted from the
exhaust when accelerating. This is of no
consequence to the running of the vehicle or
to the environment. To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least
40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears).
If possible, avoid switching off the engine
before the end of regeneration of the
filter; repeated interruptions could cause
premature deterioration of the engine oil. It
is not recommended to end regeneration of
the filter with the vehicle stationary.
This alert tells you that the particle filter
is starting to fill up (in conditions of urban
driving of exceptionally long duration: low
speeds, traffic jams etc.)
