SPEED LIMITER "LIMIT"
To resume use of the limiter,
simply reduce the pressure on the
accelerator pedal gradually and return
to a speed below that programmed.
If the vehicle is fi tted with a speed
limiter and cruise control (according
to the country in which the vehicle is
sold and the engine), these functions
cannot be activated at the same time .

The operating actions can be carried
out when stationary, with the engine
running, or with the vehicle moving. Function selected,
displaying of the
"Speed Limiter"
symbol.

This speed limiter shows the function
selection status on the instrument
panel and displays the programmed
speed:
"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 fl oor
permits exceeding of the
programmed speed.

Selecting the function
- Place the dial in the LIMIT position.
The limiter is selected but is not yet
active. The display indicates the
last programmed speed.
Programming a speed
A speed can be programmed without
activating the limiter but with the
engine running.
To memorise a speed higher than the
previous one:
- press the Set + button.
A brief press increases the speed by
1 mph (km/h).
A maintained press increases the
speed in steps of 5 mph (km/h). Activation/Deactivation (off)
Pressing this button once activates
the limiter, pressing the button again
deactivates it (OFF).
To memorise a speed lower than the
previous one:
- press the Set - button.
A brief press decreases the speed by
1 mph (km/h).
A maintained press decreases the
speed in steps of 5 mph (km/h).

Switching the function off
- Place the dial in position 0 or switch
off the ignition to switch the system
off. The last programmed speed
remains in the memory.
Exceeding the programmed
speed
Pressing the accelerator pedal in order
to exceed the programmed speed
will have no effect unless you press
the pedal
fi rmly beyond the point of
resistance .
The limiter is deactivated temporarily
and the programmed speed fl ashes.
To return to the limiter function,
reduce your speed to below the
programmed speed. Operating fault
The programmed speed is cleared and
the dashes fl ash for a few seconds.
Contact a CITROËN dealer to have the
system checked.
Flashing of the speed
The speed fl ashes:
- following forcing of the accelerator point of resistance,
- when the limiter cannot prevent an increase in the vehicle speed due
to the profi le of the road or on a
steep descent,
- in the event of sharp acceleration. Good practice
In any event, the speed limiter cannot
replace the need to observe speed limits,
nor can it replace the need for vigilance
and responsibility on the part of the driver.
Always pay attention to the profi le of the
road, take care on sharp acceleration and
stay in complete control of your vehicle.
To avoid any jamming under the
pedals:
- ensure that the mat and its fi xings positioned correctly,
- never place one mat on top of another.

VENTILATION AND AIR
CONDITIONING
Vents

"Leave them open"
For optimum distribution and diffusion
of hot or cool air in the passenger
compartment, there are adjustable
central and side vents which can be
directed sideways (right or left) towards
the top of the body. For your comfort
while driving, do not close them,
direct the fl ow of air towards the
windows instead.
The air vents directed towards the fl oor
of the vehicle complete the equipment.
Passenger compartment filter,
carbon filter
Ensure that this fi lter is in good condition and have all of the fi lter elements replaced regularly.
Refer to the "Checks" section of chapter 7.
Air conditionné

In all seasons, if fi tted on your vehicle, the air conditioning should only be used with the windows closed. However, if the interior temperature remains high after a prolonged period parked in the sun, do not hesitate to ventilate the passenger compartment for a few minutes.

If your vehicle is fi tted with automatic air conditioning, use the AUTO mode as much as possible as it permits optimised control of all of the functions: air fl ow, passenger compartment comfort temperature, air distribution, air intake mode or air recirculation in the passenger compartment.
Operate the air conditioning system for 5 to 10 minutes, once or twice a month, to keep it in perfect working order.
It is normal that the condensation created by the air conditioning system results in a fl ow of water which may form a puddle under the vehicle when parked.
If the system does not produce cold air, do not use it and consult a CITROËN If the system does not produce cold air, If the system does not produce cold air,

DE-ICING AND DEMISTING

The comfort programme may not be suffi cient to quickly demist or de-ice the windows (humidity, several passengers, ice).
In this case, select the visibility programme. The visibility programme indicator light comes on.
It activates the air conditioning, the air fl ow, the de-icing of the rear screen and provides optimum distribution of the ventilation to the windscreen and side windows.
It deactivates the air recirculation.
Press this button, with the engine running, to de-ice the rear screen and mirrors.
The de-icing indicator light comes on. The duration of de-icing depends on the exterior temperature.
Pressing the button again reactivates the de-icing.

It is possible to stop the de-icing before it is switched off automatically by pressing this button again. ADDITIONAL HEATER

To improve your comfort, vehicles fi tted with an HDi engine may be fi tted with automatic additional heating.
However, with the engine at idle or when the vehicle is stationary, it is normal to notice a high-pitched whistling and a slight emission of smoke and odour.

AUTOMATIC AIR CONDITIONING WITH SEPARATE SETTINGS
Do not cover the sunshine sensor located in the centre of the fascia. This is used to regulate the air conditioning.

Located on the centre console, the control panel is to the right of the gear lever.
1 - AUTO mode
This is the normal air conditioning operating mode.

Refer to the beginning of the "Ventilation" section of chapter 7.

The driver and front passenger can each adjust the air temperature to suit their requirements.
They can also activate or disarm the rear ventilation adjustment controls.
For your comfort, the settings selected when the ignition is switched off will be retained when it is switched on again, if the temperature in the passenger compartment has not changed signifi cantly; otherwise, operation will resume in automatic mode.
-
Press the "AUTO" button.
Depending on the comfort temperature selected, the system controls the air distribution, fl ow and intake so that the passenger compartment is comfortable and has an adequate circulation of air. You do not have to make any further adjustments.
When the engine is cold, in order to prevent a rush of cold air, the ventilation will reach its optimum level progressively.
The "AUTO" symbol is displayed.
