For 3.0 L HDi engines, the engine speed
is then limited to 3,000 rpm, then 1,500
rpm until the oil is changed. Change the
engine oil to prevent damage.
Resetting the service
indicator
A qualified workshop, equipped with the
diagnostic tool, will stop the permanent flashing
of the warning lamp after each service.
If you have serviced the vehicle yourself, reset
the service indicator as follows:
► Insert the key into the ignition switch.
► Turn it to the MAR - ON position.
► Simultaneously depress the brake and
accelerator pedals for more than 15 seconds.
Refer to the checklist in the
manufacturer's service schedule
provided on delivery of the vehicle.

Coolant temperature

If the needle is positioned between C (Cold)
and H (Hot): normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to the red
graduations.
If the needle enters the red zone or if the
warning lamp lights up:
► stop immediately, turn the ignition off. The
cooling fan may continue to run for a while, up to
approximately 10 minutes.
► wait for the engine to cool down to check the
level and if necessary, top it up.
In case of topping up
Be careful, the cooling circuit is under pressure!
To avoid any risk of burns, take a cloth and
unscrew the cap two turns to relieve the
pressure.
When the pressure has dropped, check the level
and remove the cap to top up.
If the needle remains in the red zone,
contact a CITROËN dealer or a qualified
workshop.

AdBlue® fluid ange
indicators
Once the AdBlue® tank is on reserve or after
detection of a fault with the SCR emissions
control system, when the ignition is switched on,
an indicator displays an estimate of the distance
that can be travelled before engine starting is
prevented.
In the event of a simultaneous system fault and
low AdBlue
® level, the shortest-range figure is
the one displayed.
In the event of the risk of non-starting
related to a lack ofAdBlue®
The engine start prevention system
required by regulations is activated
automatically once theAdBlue
® tank is empty.
Range greater than 1,500 miles (2,400 km)
When switching on the ignition, there is no
automatic display of range in the instrument
panel.
Range between 1,500 and 375 miles (2,400
and 600 km)
Once the 1,500 miles (2,400 km)
threshold is reached, this indicator
flashes, accompanied by a temporary message
indicating the driving autonomy expressed in
miles or kilometres before the starting of the
engine is blocked.
Each time the ignition is switched on, the alert
will be accompanied by an audible signal.
The reserve level has been reached; it is
recommended that you top up as soon as
possible.
Range less than 372 miles (600 km)
Once the 372 miles (600 km) threshold is
reached, this indicator flashes,
accompanied by a message indicating the
driving autonomy expressed in miles or
kilometres before the starting of the engine is
blocked.
The alert will be repeated with update of the
remaining range at each increment of 31 miles
(50 km) travelled.
Each time the ignition is switched on, the alert
will be accompanied by an audible signal.
It is imperative to top up as soon as possible
before the tank empties completely. Otherwise
you will not be able to restart the vehicle.
Breakdown related to a lack of AdBlue
®
0 km range reached: the AdBlue® tank is empty.
The regulatory device prevents the engine from
starting.
Unless the AdBlue
® is topped up in the
special additive tank, the vehicle will remain
immobilised.
To be able to restart the engine, you must top up with at least 4 litres of
AdBlue®. You can also call a CITROËN dealer
or a qualified workshop for the top-up
required.
For more information on AdBlue®
(BlueHDi engines) and, in particular
topping up, refer to the corresponding section.
In the event of a fault with the SCR
emissions control system
Detection
The self-diagnostic warning lamp comes
on.
Every time the ignition is switched on, the
emissions fault is confirmed by an audible signal
and a message.
If it is a temporary fault, the alert disappears
as soon as the exhaust emissions return to the
levels required by the standard.
However, if the warning lamp is still on
after 30 miles (50 km) of driving, the fault
is confirmed.
An engine start prevention system will be
activated automatically after 250 miles (400
km) travelled following this confirmation.
See a CITROËN dealer or a qualified
workshop as soon as possible.

1Fault confirmed

In addition to the previous signals, the remaining
range allowed will be displayed in miles or
kilometres in the instrument panel.
The alert will be repeated every 30 seconds with
an update of the driving range.
See a CITROËN dealer or a qualified workshop
as soon as possible.
You risk not being able to start the engine.
Starting will be prevented after 250 miles
(400 km)
At each starting attempt, the alert is
activated and the starting prevention
message is displayed.
To be able to start the engine, you must call on a
CITROËN dealer or a qualified workshop.

Ease of use and comfort
Additional pre-heater or programmable additional
heating
This is an additional, programmable and
independent system that heats the hot water
loop of the Diesel engine to facilitate starting.
It improves the performance of the defrosting
and demisting and, if fitted to the vehicle, that of
the heated seats.
The passenger compartment’s temperature rises
more quickly.
This system must be programmed to be started
before entering the vehicle.
Automatic additional heating
This is an additional system that starts
automatically when the ignition is switched on. Its
activation depends on the outside temperature
and the temperature inside the vehicle.
It switches off automatically as soon as the
heating is manually switched on.
Supplementary heating
On 2-3 seat versions, it is located under the
driver's seat with air diffusion directed towards
the front.
Complete switch-off
► Press button 3 to switch off the system. The
LED and the display go out.
Temperature
The scale is between:
– a rise in interior air temperature HI (High),
which heats up to a maximum graduation of 32,
– a cooling of interior air temperature LO (Low),
which decreases to a graduation of 16.
Air distribution
► Press one of the buttons 4 to direct the air
flow towards:
the windscreen and front side window
vents (demisting - defrosting windows),
the central and side vents (chest and
face),
the diffusers of the front and rear zones
(footwells).
Combining buttons makes it possible to refine
the air distribution.
Air flow
► Press one of the buttons 5 to increase or
decrease the air flow.
Air intake/Air recirculation
The intake of exterior air prevents the formation
of mist on the windscreen and side windows.
Recirculating the interior air isolates the
passenger compartment from exterior odours
and fumes.
This function allows hot or cold air to be delivered selectively and more quickly.
Return to exterior air intake as soon as possible
to avoid deterioration of the air quality and the
formation of mist.
► Press button 6 to activate interior air
recirculation. The indicator lamp comes on.
Pressing this button again restores exterior air
intake. The indicator lamp goes off.
Pressing button 1 also restores exterior
air intake. Returning to this position
allows the air in the passenger compartment
to be renewed and demisting. Pressing button
1 again restores the FULL AUTO function.
Additional rear ventilation
This system is complementary
to the standard passenger
compartment ventilation
equipment.




Air output
► Press control 1 to activate/deactivate the
release of air to the exterior (confirmed by the
LED coming on/going out).
Air intake
► Press control 2 to activate/deactivate
the exterior air intake into the passenger
compartment (confirmed by the LED coming on/
going out).

on the version of 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.
► Press this control to activate/
deactivate the heating. The LED lights up
if heating is activated.
When quickly defrosting and demisting, turn off
the control.
Rear heating and/or air
conditioning






If the vehicle is equipped with an additional
air conditioning unit, located at the rear of the
vehicle: the distribution rail located in the roof
and the individualised air vents ensure a perfect
diffusion of cold air.
The hot air diffused from the front air conditioning
unit to the floor is distributed at the height of the
rear passengers' feet in rows 2 and 3.
A hot air vent, located on the left-hand rear
wheel arch, may complement the system for the
rear passengers’ feet in row 3.
Activation/Deactivation
► From the driver's seat, press this
button located on the MODE control panel
to activate the operation of the rear controls. The
indicator lamp comes on.
Pressing again on this button deactivates the
operation of the rear controls. The indicator lamp
goes off.
