Intake of exterior air Recommended settings
For optimum operation of the manual system, the se ttings below are recommended:
The diode on the button is off.
This is the preferred operating
position.
Recirculation of interior air The diode on the button is lit.
Recirculation temporarily prevents
exterior odours and smoke
from entering the passenger
compartment.
Used with the air conditioning switched on
and setting of the force of blown air (from 1
to 4), recirculation enables you to obtain
the required ambient air comfort level more
quickly with both hot or cold settings.
This position should only be temporary.
When your ambient air comfort level has
been reached, return to the intake of exterior
air position to permit renewal of the air in the
passenger compartment and avoid misting.
This operating mode is preferable.

AUTOMATIC AIR CONDITIONING WITH SEPARATE ADJUSTMEN TS
Good practice
For maximum cooling or heating of the passenger compartment, it is possible to exceed the value 15 by turning until LO is displayed or the value 27 by turning until HI is displayed.
For optimum comfort, the difference between the value displayed for the driver and for the passenger should not be greater than 3.
If your vehicle is fitted with this control
panel, it is located on the centre console.
On entering the vehicle, the inside
temperature may be much colder (or
warmer) than is comfortable. There is no
advantage in changing the value displayed
in order to quickly reach the level of comfort
required. The system will use its maximum
performance to reach the comfort value set.

Driver or passenger side comfort value
The value indicated on the display
corresponds to a level of comfort and
not a temperature in degrees Celsius or
Fahrenheit.
Automatic operation Do not cover the sunshine sensor,
located on the windscreen behind the
mirror, it is used for regulation of the air
conditioning.
AUTO comfort programme
This is the normal air conditioning system
operating mode.
Press this button, the AUTO symbol is displayed. In accordance with the comfort value selected, the system controls the distribution, the fl ow and the intake of air to guarantee comfort and a suffi cient circulation of air in the passenger compartment. No further action on your part is required.
When the engine is cold, to prevent an excessive diffusion of cold air, the ventilation will reach its optimum level gradually.
For your comfort, the settings are stored when the ignition is switched off and are reinstated the next time the vehicle is started, if the temperature in the passenger compartment has not changed signifi cantly; otherwise, operation resumes in automatic mode.
Turn this control to the left or to the
right to decrease or increase the
value. A setting around the value
21 provides optimum comfort.
However, depending on your requirements,
a setting between 18 and 24 is usual.

Air flow
Press the small fan button to
reduce the flow or the large fan
button to increase the flow.
On the display, the blades of the fan darken
when the flow is increased.
Manual operation
You can, according to your requirements,
make a different selection from that offered
by the system by changing a setting.
The other functions will still be controlled
automatically. Pressing the AUTO button
restores fully automatic operation.
Intake of exterior air/Recirculation of interior air
Press this button to recirculate
the interior air. The recirculation
symbol is displayed.
Recirculation prevents exterior odours
and smoke from entering the passenger
compartment. Avoid prolonged operation
in interior air recirculation mode (risk of
condensation, odour and humidity).
Pressing this button again activates the
intake of exterior air.
Air distribution
Pressing this button several times
in succession directs the air flow
towards:
- the windscreen,
- the windscreen and footwells,
- the footwells,
- the side vents, central vents and
footwells,
- the side vents and central vents.
Deactivating the system
Press the air flow small fan
button until the fan symbol
disappears.
This action deactivates all of the system's
functions, with the exception of the air
recirculation and rear screen demisting (if fi tted
on your vehicle). Your comfort setting is no
longer maintained and is switched off.
For your comfort, do not deactivate the
system for long periods.
Pressing the large fan button or
the AUTO button reactivates the
system with the values set before
it was deactivated.
Switching the air conditioning On/Off
Press this button, the A/C
symbol is displayed and the air
conditioning is activated.
Pressing this button again switches off the
air cooling.

De-icing the rear screen and/or
mirrors
Pressing this button, with the engine
running, activates the rapid demisting-
de-icing of the rear screen and/or electric
mirrors.
This function switches off:
- when the button is pressed,
- when the engine is switched off,
- automatically to prevent excessive energy consumption. Automatic air conditioning: visibility
programme
The comfort programme (AUTO) may not
be sufficient 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 flow,
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.

CORRECT USE OF THE VENTILATION AND AIR CONDITIONING
Passenger compartment filter,
carbon filter
Ensure that this fi lter is in good condition and
have all of the fi lter elements replaced regularly.
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 flow of air towards the windows
instead.
The air vents directed towards the floor of
the vehicle complete the equipment.
Refer to the "Checks" section of
chapter 6. Air conditioning
In all seasons, if fitted 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 fitted with automatic
air conditioning, use the AUTO
mode as much as possible as it permits
optimised control of all of the functions:
air flow, 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 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 consult a PEUGEOT dealer.

Ventilation Good practice
To avoid any risk of poisoning or
asphyxiation, the heater 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.
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 heater is supplied by the vehicle’s fuel
tank. Ensure that the fuel gauge indicator
light is not at reserve.
ADDITIONAL HEATING
Coolant circuit heater
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.
Vehicles fitted with an HDi engine may be
fitted with a heater. When the engine is at
idle or the vehicle is stationary, it is normal
to notice a high-pitched whistling noise and
a slight emission of smoke and odour.

Have the heater checked at least
once a year at the beginning of winter.
Maintenance and repairs should only be
carried out by a PEUGEOT dealer.
Use recommended replacement parts only.

Improved comfort
IMPROVED COMFORT
Protection of the driving position
The Expert is fitted with a ladder type
separation with load retainer at the base,
so protecting the front occupants against
the risks of load movement. As an option, panel or glazed separation
partitions permit separation of the load
space from the cab for increased protection
and improved acoustic and
temperature-related comfort.
Treatment of the bodywork leading
to acoustic comfort
The underseal under the body, on the body
sills and on the wheel arches considerably
reduces noise and protects the body from
external attack. The Expert is treated by
cataphoresis, ensuring perfect protection
against corrosion. The anticorrosion
warranty has a duration of 6 years.
