3Delayed starting of the
heating system
The start time can be programmed between 1
minute and 24 hours in advance.
You can memorise up to three different start
times, but only programme a single delayed
start.
To perform a daily start at a fixed time, reprogramme the memorised time each
day.
► Press button 3; the screen comes on.
The - -:- - symbol or the previous memorised
time and the corresponding preset number (1, 2
or 3) are displayed for 10 seconds.
To recall the other preset times, press button 3 several times before the end of
the 10 seconds.
Within 10 seconds, press one of the buttons 1 to
select the desired start time.
The memorisation is confirmed by the
disappearance of the start time, the display of
the preset number (1, 2 or 3) and the lighting of
the screen.
By default, preset times are already
memorised in the system (1 = 06:00, 2 =
16:00, 3 = 22:00). Any change cancels and
replaces the previous preset time.
If the battery is disconnected, the default
preset times will be restored.
Cancelling the programming
► To delete the programmed start time, briefly
press button 3.
The lighting of the screen and the preset number
(1, 2 or 3) go off.
Recalling one of the preset
start times
► Press button 3 as many times as necessary
until the number corresponding to the desired
preset start time (1, 2 or 3) appears.
After ten seconds, the time disappears but
remains memorised while the corresponding
number (1, 2 or 3) and the screen remain on.
Setting the operating
duration
The operating duration can be set between 10
and 60 minutes.
► Press and hold button 3.
► Press simultaneously one of the buttons 1.
The time and the time setting indicator lamp light
up.
► Press and hold button 3 again.
► Press simultaneously one of the buttons 1
again.
The programmed operating duration is displayed
and the heating or ventilation cycle indicator
lamp flashes.
► Set the duration by pressing one of the
buttons 1.
The memorisation is confirmed by the
disappearance of the duration on the screen or
by pressing button 3 again.
Switching the heating off
In the event of a delayed start, the heating
switches off automatically at the end of the
programmed duration.
► In the event of an immediate start, press
button 2 again to switch it off manually.
The heating cycle indicator lamp and the screen
switch off.
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.
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.

Practical information
A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
Screenwash and headlamp
washer fluid
To check the level or top up this fluid on
vehicles fitted with headlamp washers,
immobilise the vehicle and switch off the engine.
Reservoir capacity: approximately 5.5 litres.


To access the filler cap, pull the telescopic filler
neck and unclip the cap.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular on the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
