Heating and air conditioning
General notes
The power of the heating depends on the temperature of the coolant. There-
fore, maximum power is only obtained when the engine has reached operat-
ing temperature.
The temperature and the humidity of the air is reduced when the system
cools the interior of the vehicle. This therefore increases the comfort of all
vehicle occupants when outside temperatures and humidity are high. It also
helps prevent the windows from misting 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 windscreen clear of ice, snow or
leaves to ensure unimpaired heating and cooling.
When the air conditioning is on, condensation can drip from the evaporator
in the air cooling system and form a pool underneath the vehicle. This is
normal and does not indicate a leak!
WARNING
● All windows must be clear of ice, snow and condensation for driving
safety. Therefore, make sure you familiarise yourself with the correct use
of heating and ventilation, window demisting and defrosting and cooling.
● Never use the air recirculation system for too long, as it prevents
fresh air from entering the vehicle and “used” air can cause tiredness, re-
duce your attention span and cause the windows to mist over. This in-
creases the risk of an accident. Switch off the air recirculation 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 evap-
orator of the air conditioning system. This causes a persistent, unpleasant
smell while the system is running that is time-consuming and expensive
(evaporator replacement) to eliminate.
● Never cover the air outlets to ensure the system operates correctly.
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 an excessive solar radiation, it
is best to open the windows or doors to allow the hot air to escape.
