Heating and air conditioning
Heating and air conditioning
General notes
The power of the heating depends on the
temperature of the coolant. Therefore, maxi-
mum power is only obtained when the en-
gine has reached operating temperature.
The temperature and humidity of the air in-
side the vehicle decrease when the cooling
system is turned on. This therefore increases
the comfort of all vehicle occupants when
outside temperatures and humidity are high.
It also helps prevent the windows from mist-
ing over during cold periods of the year.
The air recirculation system can be switched
on temporarily to increase the cooling effect.
Keep the air intake slots in front of the wind-
screen clear of ice, snow or leaves to ensure
unimpaired heating and cooling.
When the air conditioning is on, condensa-
tion can drip from the evaporator in the air
cooling system and form a pool underneath
the vehicle. This is normal and does not indi-
cate a leak!
WARNING
●
All windows must be clear of ice, snow and
condensation for driving safety. Therefore,
Heating and air conditioning
make sure you familiarise yourself with the
correct use of heating and ventilation, win-
dow demisting and defrosting and cooling.
Never use the air recirculation system for
●
too long, as it prevents fresh air from enter-
ing the vehicle and used air can cause tired-
ness, reduce your attention span and cause
the windows to mist over. This increases the
risk of an accident. Switch off the air recircu-
lation system as soon as the windows begin
to mist over.
Note
●
Used air escapes through ventilation slots
in the rear of the luggage compartment.
Smoking is not recommended while the air
●
recirculation system is in use, as the smoke
drawn from the interior of the vehicle settles
in the evaporator of the air conditioning sys-
tem. This causes a persistent, unpleasant
smell while the system is running that is
time-consuming and expensive (evaporator
replacement) to eliminate.
To ensure proper functioning, never cover
●
the air outlets.
Economic use of the air conditioning
system
When the air conditioning is switched on, the
compressor consumes engine power and has
influence on fuel consumption.
If the vehicle interior has overheated due to
excessive solar radiation, it is best to open
the windows or doors to allow the hot air to
escape.
While in motion, the air conditioning should
not be switched on if the windows are open.
If the interior temperature can be reached
without switching on the air conditioning, the
fresh air mode should be used.
For the sake of the environment
Saving fuel reduces emissions.
Faults
If the air conditioning does not work at out-
side temperatures above +5 °C (+41 °F) then
the system is faulty. This may be due to one
of the following reasons:
●
One of the fuses has blown. Check the fuse
›››
and replace if necessary
page
●
The air conditioning compressor has
switched off temporarily because of in-
creased engine coolant temperature

If you cannot repair the fault yourself or
where cooling power continues to drop,
switch off the system. Contact a specialised
service.
