DEMISTING AND DEFROSTING

Manual mode
Direct the control to this air
distribution setting.
For faster and more effective
demisting and defrosting of the
windscreen:
Defrosting the rear screen
and mirrors
Only operates when the engine
is running. Pressing this button
activates the rapid demisting-
defrosting of the rear screen and
door mirrors.
This function switches off automatically to
prevent excessive energy consumption. It
stops when the engine is switched off but
resumes when the engine is started again.
Pressing this button switches the function off.


- increase the air flow setting,

- move the exterior air intake
control temporarily to air
recirculation.
Returning to the exterior air
intake position permits renewal
of the air in the passenger
compartment.
Windscreen and side windows
The ventilation outlets located at the base
of the windscreen and the side vents for the
side windows increase the effectiveness
of the demisting and defrosting. Do not
obstruct these air outlets.
The pollen filter continuously and effectively
filters dust.
Air recirculation (which can be activated by
the driver or the passenger) isolates the
passenger compartment from the exterior
atmosphere. However, this position should
only be used temporarily, normal use is to
drive with the control positioned with the
exterior air intake open.

ADDITIONAL HEATING SYSTEMS

Supplementar
y heating

On the 2-3 seats version, this is located
under the seat on the driver's side with air
diffusion directed forwards.
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 duct 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 programmableadditional 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.

PROGRAMMABLE ADDITIONAL HEATING
If your vehicle is fitted with separate
programmable heating: it gradually brings
the engine up to a good temperature to
facilitate starting. An integrated clock permits programming of
its start time. The passenger compartment
will be heated more quickly. Heating cycle indicator lamp

Cancelling the programming
Press this button briefly to clear

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 is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator lamp is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
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 system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use only genuine replacement parts.
Recalling one of the pre-selected
start times
Press this button as many times
as necessary until the number
corresponding to the required
pre-selected start time (e.g. 2)
appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the screen remain on.
Switching off the heating

Press this button.
The heating cycle indicator lamp
and the screen are switched off.
Two different types of equipment

The additional heating is separate and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier.
This also facilitates passenger compartment
heating, demisting and defrosting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.

SAFETY
ANTI-SLIP REGULATION (ASR) AND ELECTRONIC STABILITY
PROGRAMME (ESP)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting on the brakes of
the drive wheels and on the engine. It also
allows the directional stability of the vehicle
to be improved on acceleration.
Use the ESP to hold your course without
attempting to countersteer. If there is a variation between the trajectory
followed by the vehicle and that required
by the driver, the ESP system automatically
acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.
In certain exceptional conditions (when
starting a vehicle stuck in mud or snow, or
on loose ground...), it could prove useful
to deactivate the ASR system to make the
wheels spin and regain grip.

Operation of the ASR and ESP
systems
The LED flashes when the ASR
or ESP is triggered. Press this button.
The LED on the button comes on: the ASR
system no longer acts on the engine
operation, but continues to act on the brakes.
Operating fault

When a malfunction of the ASR
system occurs, this warning lamp
comes on, accompanied by an
audible signal and confirmed by a
message on the screen.
