Cancelling the programming Press this button briefly to clear
the programmed start time.
The display lighting and the
pre-selection number (e.g. 1) are
switched off. 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 light 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 recommended replacement parts only.
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 display remain lit.
Switching off the heating
Press this button.
The heating cycle indicator light
and the display are switched off. Two different types of equipment
The additional heating is autonomous 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, de-icing and demisting.
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.

Driving safety
TRACTION CONTROL (ASR) AND DYNAMIC STABILITY CONTROL (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
disarm the ASR system to make the wheels
spin and regain grip.
Operation of the ASR and ESP
systems The luminous diode flashes when
the ASR or ESP is triggered. Press this button.
The diode on the button comes on: the
ASR system no longer acts on the engine
operation, but continues to act on the brakes.
MALFUNCTION
When a malfunction of the ASR
system occurs, this warning light
comes on, accompanied by an
audible signal and confirmed by a
message on the display.
