156 Air conditioning
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves
comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•
The engine is not running.
•
The button is disconnected.
AC
•
The outside temperature is below +3°C.
•
The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioner fuse is faulty.
•
Another fault in the vehicle. Have the air conditioner checked by a quali-
fied workshop.
Caution
•
If you suspect that the air conditioner is damaged, switch it off with button
AC to prevent further damage and have it checked by a qualified workshop.
•
Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a qualified work-
shop.
Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a puddle
underneath the vehicle. This is completely normal and there is no need to
suspect a leak.
•
Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this purpose. Therefore, do not cover these
slots with items of clothing or other objects.
•
The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the vehicle has been overheated
by sun, the air inside can be cooled faster by opening the windows for a short
time.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
•
It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.
