CRUISE CONTROL
"This is the speed at which the driver wishes
to travel".
This aid to driving in free-flowing traffic
conditions enables the vehicle to maintain a
constant speed programmed by the driver,
except when a considerable load is carried
on a steep gradient.
In order to be programmed or activated,
the vehicle speed must be greater than
approximately 25 mph (40 km/h), with at
least 4th gear engaged.
If your vehicle is fitted with cruise control,
this is displayed on the instrument panel by
an indicator light located in the rev counter. Function selected.
Function deactivated.

Steering wheel controls
Selecting the function - ON When the selection is set
to ON , this switches the
function on.
If your vehicle is fi tted with
this display, a message confi rms the action. Temporary deactivation
Press the brake or clutch pedal.
The indicator light is switched off but the
programmed speed remains in the memory.
To return to this speed, refer to the action
"Restore - RES".
If the ESP or ASR comes into operation,
the cruise control function is deactivated
temporarily.
Programming a speed
Accelerate to the required speed, with 4th or
5th gear engaged.
Move the control upwards (+) to store this
speed.
Release the pressure on the accelerator
pedal, the vehicle will maintain this speed. Restore - RES
To restore the vehicle’s programmed
speed, gradually return to the
chosen speed and press
RES .
The indicator light comes on, the cruise
control function is restored. Changing the programmed speed
while the cruise control is in
operation
You can:
- increase the speed in steps, by means of
brief presses, or continuously by pressing
and holding the control upwards (+ sign),
Temporary exceeding of the speed
When the cruise control is active, it is
still possible to exceed the programmed
speed by pressing the accelerator pedal (to
overtake another vehicle for example).
- decrease the speed continuously
by pressing and holding the control
downwards (- sign).

Cancelling the programmed speed
When the vehicle stops, after the ignition is
switched off, the system no longer stores
any speed. Good practice
When changing the programmed reference
speed by pressing and holding the control,
take care as the speed may increase or
decrease rapidly.
Do not use the cruise control on slippery
roads or in heavy traffic.
On a steep gradient, the cruise control will
not be able to prevent the vehicle from
exceeding the programmed speed.
The cruise control cannot, in any
circumstances, replace the need to comply
with speed limits nor can it replace the need
for vigilance and responsibility on the part
of driver.
It is advisable to leave your feet near the
pedals.
To prevent the mat from becoming caught
under the pedals:
- ensure that the mat is positioned
correctly,
- never fit one mat on top of another.
Switching the function off - OFF
Place the dial in the
OFF position, the
indicator light is switched off, or switch off
the ignition to switch everything off.
Operating fault
In the event of a malfunction, the function is
switched off and the indicator light switches off.
Contact a CITROËN dealer to have the
system checked.

Direct the control to this air
distribution setting.
For faster and more effective
de-icing and demisting of the
windscreen: De-icing the rear screen and mirrors
Only operates when the engine
is running. Pressing this button
activates the rapid demisting-
de-icing of the rear screen and
mirrors.
This function switches off automatically to
prevent excessive energy consumption. It
stops when the engine is switched off but
resumes when the engine is started again.
Pressing this button switches the function off.
- increase the air flow setting,
- move the exterior air intake control temporarily to air
recirculation.
Returning to the exterior air
intake position permits renewal
of the air in the passenger
compartment.
Windscreen and side windows
The ventilation outlets located at the base
of the windscreen and the side vents for the
side windows increase the effectiveness of
the de-icing and demisting. Do not obstruct
these air outlets.
The pollen filter permits continuous and
effective filtering of dust.
The air recirculation (which can be activated
by the driver or the passenger) isolates the
passenger compartment from the exterior
atmosphere. However, this position should
only be used temporarily, the norm is to
drive with the control positioned with the
exterior air intake open.

CORRECT USE OF THE AIR CONDITIONING
In order to be effective, 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. For even air distribution, ensure that the
exterior air intake grille located at the base
of the windscreen is not obstructed and that
the side and central vents, the air outlets on
the floor and the air extractor at the rear are
open.
The air conditioning is useful in all seasons
as it eliminates condensation and air
humidity. Operate the air conditioning system for
5 to 10 minutes, once or twice a month,
to keep it in perfect working order.
Have the filter elements (air filter and
passenger compartment filter) replaced
regularly. If you drive in a dusty environment,
have them replaced twice as often.
It is normal that the condensation created by
the air conditioning system results in a flow
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 contact a CITROËN dealer.
"Leave them open"
For optimum distribution and diffusion of hot
or cool air in the passenger compartment,
there are: 4 adjustable central vents, of
which 2 can be directed sideways (right
or left) towards the top of the body and
4 side vents which can be directed towards
the passengers. The air vents directed
towards the floor of the vehicle complete the
equipment.

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 rail 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 an additional passenger compartment
heating system which supplements the
standard equipment.
It can operate independently of the engine.
Depending on the level of finish of the
equipment, its start-up can be programmed.
Additional heater or programmable
heating
This is an additional and autonomous
system which heats the diesel engine hot
coolant loop to make starting easier.
It improves the de-icing and demisting
performance and that of the heated seats, if
fitted in 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.
