Activation/Deactivation This control, located on the
control pad at the right-hand
end of the fascia, enables you to
activate/deactivate the operation
of the rear controls from the driver ’s seat.
The first press activates (diode lit).
A second press deactivates (diode off). To deactivate the blower, place the control in
position 0.
However, a safety device will ventilate the
rear circuit automatically, even if the control
is in position 0, to prevent the formation of
condensation.
Air flow The force of the blown air, via
the vents, varies from 1 to the
strongest 4.
To obtain a comfortable level of
ambient air, remember to adjust this control. Comfort value adjustment

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.

Improved comfort
SOUNDPROOFING
The RELAY benefits from a suspension
which contributes to improving general
comfort.
These developments also contribute to
reducing noise disturbance.
IMPROVED COMFORT
TREATMENT OF THE BODYWORK
LEADING TO ACOUSTIC COMFORT
The underseal under the body, on the body
sills and on the wheel arches considerably
reduces noise and protects the body from
external attack. The RELAY is treated by cataphoresis,
ensuring perfect protection against
corrosion. The anticorrosion warranty has a
duration of 6 years.
