138Air conditioning
WARNING
For your safety, the windows should never be fogged up or covered with
snow or ice. This is essential to ensure good visibility. Please familiarise
yourself with the correct operation of the heating and ventilation system,
including the demist/defrost functions for the windows.
Note
Please consider the general notes.

ing controls on the dash
panel
Interior heating
– Disconnect the cooling system using button ⇒ Fig. 103 AC
(the
button light turns off).
– Turn the temperature selector A
to set the desired temperature
inside the vehicle. –
Turn the blower switch to any of the settings 1-4.
– Set the air distribution control C
to the air flow configuration
desired: (towards the windscreen), (towards the chest),
(towards the footwell) and (towards the windscreen and
footwell areas).
Interior cooling
– Connect the cooling system with button AC
(the button light
should light up).
– Turn the temperature control switch until the desired interior
temperature is reached.
– Turn the blower switch to any of the settings 1-4.
– Set the air distribution control to the air flow configuration de-
sired:
(towards the windscreen), (towards the chest), (towards the footwell) and (towards the windscreen and
footwell areas).
Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Coolant system
When the air conditioning is switched on, the temperature and the air hu-
midity go down. This way, if the outside humidity is extreme, the air condi-
tioning prevents the misting of the windows and therefore, comfort is im-
proved.
If the air conditioning does not work, this may be due to the following rea-
sons:
● The engine is stationary.
● The fan blower is switched off.

WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● The high voltage element of gas discharge bulbs* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. Other-
wise, a short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.

For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface.
1)
With this type of headlight, the user can replace the turn signal bulb. Replacement of the
dipped/main beam bulb must be done by a Technical Service, given that complex elements
must be removed from the vehicle and the automatic control system that incorporates it
must be reset.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) In the event that there is a fault in the LEDs, the complete headlight must be replaced.
