Heating and coolingAir conditionerControls
The air conditioner is designed to keep the passenger
compartment at the temperature you find most comfort-
able at all times of the year.Fig. 69 Air conditioner controlsRecommended settings:
– Turn the control ⇒fig. 69 to the right to switch the air
conditioner on.
– Set the temperature to 22 °C (72 °F).
– Press the button ⇒fig. 69.
This setting quickly provides a comfortable temperature inside the
vehicle. If necessary it can be changed to suit individual preferences
or particular circumstances.
The air conditioner provides heating and ventilation and also cools
and dehumidifies the air inside the vehicle.
The air conditioner is fully automatic, and will maintain the desired
temperature at a constant level. To achieve this, the temperature of
the air supplied to the interior, the blower speed (volume of air
delivery) and the air distribution are regulated automatically. The
system also allows for the effect of strong sunlight, so there is no
need for manual adjustment. For these reasons it is advisable to use
the automatic mode for the comfort of all the passengers in virtually
all conditions throughout the year ⇒page 78.
Please note:
The humidity of the air is automatically reduced when the system
cools the interior of the vehicle. This helps to prevent condensation
on the windows. The air conditioner (compressor) will be switched
off automatically at low outside temperatures (below zero) and will
no longer dehumidify the air inside the vehicle.
If the humidity and temperature outside the vehicle are high,
condensation can drip off the evaporator in the air cooling system
and form a pool underneath the vehicle. This is normal and does not
indicate a leak.
If the outside temperature is low, the blower normally only switches
to a higher speed once the coolant has warmed up sufficiently (this
does not apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner
compressor is temporarily switched off when pulling away from a
standstill with full throttle.

Regulating the blower speed

– Turn the control ⇒page 75, fig. 69 to the desired
setting for the blower speed (amount of air to be deliv-
ered).In automatic mode, the air conditioning system automatically regu-
lates the blower speed according to the interior temperature.
However, you can also adjust the blower speed manually.
Note
The blower speed will automatically be adjusted if the difference
between the selected temperature and the actual temperature in
the vehicle is too high. This ensures that the selected temperature
is reached as quickly as possible.
Air distributionFig. 70 Dashboard: Location of air outlets– Turn the rotary control ⇒page 75, fig. 69 to the
desired setting.
– The outlets can be opened and closed by turning the
adjustment ring.
– The direction of air delivery from these outlets can be
adjusted horizontally and vertically using the adjuster in
the centre of each outlet grille.Air distribution:•

Technical data When driving through a tunnel or in queues of traffic, to prevent
fumes entering the interior of the vehicle.
WARNING
For reasons of safety you should not leave the air recirculation
switched on for too long. This mode prevents fresh air from
entering the vehicle, so the windows can mist over if the air
cooling is switched off. Bad visibility can cause an accident.AC mode Activating the AC mode
– Press the button ⇒page 75, fig. 69.
Deactivating the AC mode
– Press the button again.In the AC mode, the air cooling system is switched on and the
heating and ventilation are regulated automatically.
Note
If the LED in the AC button should continue to light up when the AC
mode has been switched off (i.e. the air conditioner has been
switched off) this is due to a defect in one of the air conditioner
components. If a malfunction should occur, please contact a quali-
fied workshop.
Economical operation of the air conditioner
Economical operation of the air conditioner will help to
save fuel.When the air conditioner is operating in the cooling mode it
reduces engine power and increases fuel consumption. To
ensure that the cooling mode is activated only when really
necessary, please note the following points:
– Switch the AC mode off if you wish to save fuel.
– Switch the AC mode off if you decide to open the
windows while driving.
– If the vehicle has heated up after standing in the sun,
open the windows and doors for a short time to cool the
vehicle.
For the sake of the environmentBy saving fuel you also reduce the amount of pollutants emitted
from your vehicle.Rear window heating

The rear window heating helps to demist the rear window.– Press the
 button ⇒page 75, fig. 69 to switch the rear
window heating on or off.
The rear window heating only works when the engine is running. An
indicator lamp in the button lights up when the rear window heater
is switched on.
The rear window heating switches off automatically after about
10 minutes.

Switching off the engineOn vehicles with R tronic, the engine can be switched off in
neutral (N) or in any gear (1 - 6 or R).
– Turn the ignition key to position ⇒page 81, fig. 72.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo and the power steering system work only
when the engine is running. You need more strength to steer and
brake the vehicle when the engine is switched off. This would
mean a greater risk of accidents and serious injury, because you
cannot steer and brake in the normal manner.Caution
•
If the engine has been working hard for a long time, there is a risk
of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason,
you should leave the engine idling for a few minutes or drive at a
moderate speed to let the engine cool down before switching it off
⇒page 139.
•
Because the engine can get very hot after working hard, do not
park the vehicle on surfaces which could catch fire (e.g. on grass or
at the forest edge).Note
After the engine is stopped the radiator fan may run on for up to
10 minutes, even if the ignition is switched off. The fan may also
start running again after some time if the coolant temperature rises
due to a build-up of heat, or if the engine is hot and the engine
compartment is heated up further by direct sunlight.
