Air outlet
Press this control to activate
extraction of air to the outside; the
LED comes on. Press again to
switch off.
Air intake
Pressing this control activates the
exterior air intake into the passenger
compartment; the LED comes on.
Press again to switch off.
Additional heating
systems
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
per formance and that of the heated seats, if
fitted to the vehicle.
Automatic additional
heating
This is an additional system which starts
automatically when the ignition is switched
on. Its activation depends on the exterior
temperature and the temperature inside the
vehicle.
It switches off automatically once the heating
system is started manually. The passenger compartment heating is brought
up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle.
Supplementary heating
On the 2-3 seats model, this is located under
t he seat on the driver's side with air diffusion
directed forwards.
On the 5 -9
seats model, it is
located at the rear. Depending
on the model, the air diffusion
is either direct from the rear
or comes from the rail located
under each of the two rows of
seats.
F

P
ress this control to activate/
deactivate the heating. The
LED comes on if the heating is
activated.
When rapid demisting and defrosting is
required, switch off the control.
Rear heating and/or air
conditioning
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
per fect diffusion of cold air.
Ease of use and comfort

50
To avoid the risks of poisoning or
asphyxia, the additional heating must
not be used, even for short periods, in
a closed environment such as a garage or
workshop which are not equipped 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 fed by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when refuelling to avoid any risk of fire or
explosion!
The temperature near the heating
system must not exceed 120°C. A higher
temperature (e.g. when baking the
paint) could damage the components of
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 top up if necessary.
For more information on Checking levels ,
refer to the corresponding section.
Then press the programme selection
button before switching the heating on
again.Recommendations for ventilation and air conditioning
In order for these systems to be fully effective,
follow the operation and maintenance
guidelines below:
F

T
o ensure that the air is distributed evenly,
keep the external air intake grilles at the
base of the windscreen, the nozzles, the
vents, the air outlets and the air extractor
in the boot free from obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used for
regulation of the automatic air conditioning
system.
F

O
perate the air conditioning system for
at least 5
to 10 minutes once or twice
a
month to keep it in per fect working order.
F

E
nsure that the passenger compartment
filter is in good condition and replace
the filter elements periodically. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it helps both to
purify the air breathed by the occupants
and to keep the passenger compartment
clean (reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold air,
switch it off and contact a
CITROËN
dealer or a
qualified workshop.
When towing the maximum load on a
steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period.

Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a
trailer before having driven at
least 620
miles (1,000 kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a
genuine CITROËN
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic immobiliser
device.
This device locks the engine supply system.
It activates automatically when the key is
removed from the ignition.
This warning lamp goes off after the
key has been recognised, the ignition is
switched on and the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key
and have the faulty key checked by
a
CITROËN dealer.
Note the number of the keys carefully; in
case of loss, inter vention by the CITROËN
dealer will be more efficient and quicker
if you present this number and the
confidential card.
When the ignition switch is turned on, a
dialogue is set up between the key and the
electronic immobiliser.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even when it
is in your pocket, may result in involuntary
unlocking of the doors.
The simultaneous use of other high
frequency equipment (mobile telephones,
domestic alarms, etc.), may inter fere
with the operation of the remote control
temporarily.
The remote control does not operate
while the key is in the ignition, even if the
ignition is off, except for reinitialisation.

workshop.
Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a
level drops significantly, have the
corresponding system checked by a
CITROËN
dealer or a
qualified workshop.
If you have to remove/refit the engine
cover, handle it with care to avoid
damaging the fixing clips.
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive. Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a
CITROËN dealer or
a qualified workshop and dispose of it in
the containers reser ved for this purpose.
Engine oil level
Check this regularly and top up as
necessary between two oil changes
(the maximum consumption is
0.5
litres for 620 miles (1,000 km)).
Make the check with the vehicle
standing level, engine cold, using
the dipstick.

For access to the reser voir filler cap, remove
the protective cover by turning its three fixing
screws a quarter turn, then remove the second
cover fitted to the cap.
Engine coolant level
Check the coolant level regularly.
It is normal to top up this fluid
between two services.
Check the coolant level regularly,
according to the use made of your vehicle
(every 3,000
miles (5,000 km)/3 months);
if necessary, top up using coolant
recommended by the manufacturer.
The check and top up must only be done
with the engine cold.
A low coolant level presents a
risk of
serious damage to your engine.
When the engine is hot, the temperature of the
coolant is regulated by the electric fan. This
may operate with the ignition off; furthermore,
because the cooling system is under pressure,
wait for at least one hour after the engine has
stopped before carrying out any work. F
