wait for the engine to cool down in

order to check the level and top it up if
necessary. Follow this advice.
When topping-up
Caution, the cooling system is pressurised.
In order to avoid any risk of scalding, place
a cloth around the cap and unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap to check the level and top-up.
Refer to the "Checks - Fuel" section. If the needle remains in the red zone,

Supplementary heating
On the 2-3 seats version, this is located
under the seat on the driver's side with air
diffusion directed forwards.
rEAr HEAtI n G A nd / O r AI r
c O nd I t IO n I n G
If your vehicle is fitted with an additional
air conditioning unit, located in the rear of
the vehicle: the distribution rail located in
the roof and the individual diffusion vents
provide a perfect diffusion of cold air.
The warm air diffused at the floor,
from the
front air conditioning unit, is
distributed
at the feet of the rear passengers
of rows 2 and 3.
A warm air diffusion vent, located on the rear
left wheelarch, may complete the assembly
for the feet of the rear passengers of row 3.
Additional heating
This is passenger compartment heating,
additional to the standard equipment.
It can operate independently of the engine.
Additional heater or programmable
additional heating
This is an additional, programmable and
separate system which heats the Diesel
engine hot coolant loop to make starting
easier.
It improves the demisting and defrosting
performance and that of the heated seats, if
fitted to the vehicle.
The passenger compartment heating is
brought up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle. On the 5-9 seats version, it is
located at the rear. Depending
on the model version, the air
diffusion is either direct from the
rear or comes from the rail located under
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The
LED
is on if the heating is
activated.
When rapid demisting and defrosting is
required, switch off the control.
Automatic additional heating
This is an additional system which starts
automatically when the ignition is switched
on. Its activation depends on the ambient
temperature and the temperature inside the
vehicle.
It switches off automatically once the
heating system is started manually.

Have the additional heating checked at
least once a year at the beginning of
winter. Maintenance and repairs should only
be carried out by a CITROËN dealer or a
qualified workshop.
Use only genuine replacement parts.
Switching off the heating
In the case of deferred operation, the
heating stops at the end of the programmed
period.
Good practice
To avoid any risk of poisoning or
asphyxiation, the additional heating must
not be used, even for short periods, in
an enclosed space such as a garage or
workshop which is not fitted with an exhaust
gas extraction system.
The additional heating switches off when the
battery voltage is low, so as to allow engine
starting.
The additional heating is supplied by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion. The temperature near the heater must not
exceed 120
°C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The additional heating is fitted with
a temperature limiter which cuts off
the combustion in the event of engine
overheating due to a lack of coolant. Check
the level and if necessary top-up following
the advice given in the "Checks - Levels"
section. Then press the programme
selection button before switching the heating
on again.
Setting the operating period
The period of operation can be set to
between 10 and 60 minutes.
Press and hold the "set" button.
At the same time press the "<"
or ">" button.
The time and the time setting
indicator come on.
Press and hold the "set" button again.
At the same time press the "<" or ">" button
again.
The programmed operating period is
displayed and the heating or ventilation
cycle indicator flashes.
Adjust the period by pressing the "<" or ">"
button.
The setting is confirmed by the period
disappearing from the screen or by pressing
the "set" button again In the case of immediate
operation, press this button
again
to switch off manually.
The heating cycle indicator and
the screen go off.

driving advice
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.
c

ooling: 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
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.
r

ear parking sensors: the system is
deactivated while the vehicle is towing with a
genuine CITROËN towbar fitted.
Refer to the "Technical data -
Identification markings" section.

cooling system
Check the coolant level regularly,
according to the use made of your
vehicle (every 3 000 miles or 5 000 kms
/
3

months);
if necessary, top-up using coolant
recommended by the manufacturer.
Topping-up the coolant between services is
normal.
The check and top-up must be done with the
engine cold.
A low coolant level presents the risk of
serious damage to your engine. For access to the header tank filler cap,
remove the protective cover by turning its
three fixing screws a quarter turn.
Only use the fluid recommended by the
manufacturer. Otherwise, you risk seriously
damaging your engine. When the engine
is warm, the temperature of the coolant is
controlled by the engine fan. As this fan can
operate with the ignition key removed and
because the cooling system is pressurised,
wait for at least one hour after the engine
has stopped before carrying out any work.
To avoid the risk of scalding, with a cloth
around the cap, slacken the cap by a quarter
turn to release the pressure. When the
pressure has dropped, remove the cap and
top-up the level with coolant.changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer's service schedule.
Use brake fluid recommended by the
manufacturer, meeting the DOT4 standard.
The level must be between the MI
n and
MA
x marks on the reservoir.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer or a qualified workshop
as soon as possible. Engine oil grade
When topping-up, the oil selected must meet
the manufacturer's requirements. Oil change
It is imperative that this is carried out at the
intervals specified in the manufacturer's
service schedule. Ask for advice from a
CITROËN dealer.
Refill the engine oil using the procedure
described for topping-up.
Check the level after filling (never exceed
the maximum mark).
