Deactivate this control by keeping the stalk
pulled towards the steering wheel for more
than 2 seconds. If your vehicle is fitted with this function:
when you leave your vehicle, the dipped
beam headlamps remain on for the selected
duration (when leaving a car park for
example).
You can adjust the sensitivity of the
sunshine sensor.
Refer to the "Technology on board -
Vehicle configuration" section.
If your vehicle is fitted with this function, the
dipped beam headlamps are switched on
automatically if the light is poor.
In fog or snow, the sunshine sensor may
detect sufficient light. Therefore, the lamps
will not be switched on automatically. If
necessary, you must switch on the dipped
beam headlamps manually.
They are switched off when the light returns
to a sufficient level.
LED DAYTIME RUNNING LAMPS
On starting the vehicle, in daylight the LED
daytime running lamps come on automatically.
If the sidelamps and headlamps are switched
on manually or automatically, the daytime
running lamps go off.
Programming
For countries where exterior lighting by
day is not a legal requirement, you can
activate or deactivate the function via the
configuration menu.
The lamps are switched off automatically
when the ignition is switched off.

SPEED LIMITER
"This is the selected speed which the driver
does not wish to exceed".
This selection is made with the engine
running while stationary or with the vehicle
moving. The minimum speed which can be
programmed is 20 mph (30 km/h).
The speed of the vehicle responds to the
pressure of the driver's foot as far as the
accelerator pedal point of resistance which
indicates that the programmed speed has
been reached. However, pressing the pedal beyond this
point of resistance to the floor permits
exceeding of the programmed speed. To
resume use of the limiter, simply reduce
the pressure on the accelerator pedal
gradually and return to a speed below that
programmed.
The operating actions may be carried out
when stationary, with the engine running,
or with the vehicle moving.
This speed limiter shows the status of the
system and the programmed speed in the
instrument panel screen:

ADDITIONAL HEATING SYSTEMS
Supplementary 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 programmable additional 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
the programmed start time.
The screen illumination 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 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.

Driving safely
TRAJECTORY CONTROL SYSTEMS
Switching off
This system cannot be deactivated by
the driver.
Dynamic stability control (DSC)
The electronic stability programme acts on
the brake of one or more wheels and on the
engine to keep the vehicle on the trajectory
required by the driver, within the limits of the
laws of physics.
With the DSC system, maintain course
without trying to countersteer.
Operation
The DSC system is activated automatically
each time the vehicle is started. Operating fault
Illumination of this warning lamp,
accompanied by an audible signal
and confirmed by a message
in the instrument panel screen,
indicates a fault with the DSC system.
Have it checked by a CITROËN dealer or a
qualified workshop. Operation
This system is activated automatically every
time the vehicle is started.
In the event of a problem of adhesion or
trajectory, this system comes into play.
Switching off
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow,
on soft ground...), it may be advisable to
deactivate the ASR system, so that the
wheels can spin freely and regain grip.
- Press this button, located in the
middle of the dashboard, to deactivate
the system.
Anti-slip regulation (ASR)
Anti-slip regulation (also known as traction
control) optimises traction, avoiding wheel
spin by acting on the brakes of the driving
wheels and the engine.
If the button's warning lamp comes
on, accompanied by a message in the
instrument panel screen, this indicates that
the ASR system is deactivated.
It comes into operation in the
event of a grip or trajectory
problem.
This is indicated by flashing of this warning
lamp in the instrument panel.
