Note
The arrangement of the controls and switches and the location of some items on
right-hand drive models may differ from that shown in » Fig. 1. The symbols on
the controls and switches are the same as for left-hand drive models.2021222324252627282930313233349Cockpit
The interior temperature can be set between +18 °C and +26 ℃. The interior tem-
perature is regulated automatically within this range.
If a temperature lower than +18 °C is selected, a blue symbol lights up at the start
of the numerical scale.
If a temperature higher than +26 °C is selected, a red symbol lights up at the start
of the numerical scale.
At both end positions, Climatronic runs at maximum cooling/heating output and
the temperature is automatically not regulated.
Controlling blower
The Climatronic system controls the blower stages automatically in line with the
interior temperature. However, the blower stages can be manually adapted to
suit your particular needs.
Automatic mode
The automatic mode is used in order to maintain a constant temperature and to
demist the windows in the interior of the car.
If the warning light in the top right corner of the button
lights up, the Clima-
tronic operates in “HIGH”-mode. The “HIGH” mode is the standard setting of the
Climatronic.
Upon pressing the
button again, the Climatronic switches to “LOW”-mode
and the indicator light in the top left corner lights up. The Climatronic uses only in this mode the lower blower speed. However taking into account the noise level,
this is more comfortable, yet be aware that the effectiveness of the air condition-
ing system is reduced particularly if the vehicle is fully occupied.
By pressing the button
again, it is changed to “HIGH”-mode.
Automatic mode is switched off by pressing one of the buttons for the air distri- bution or by increasing/decreasing the blower speed. The temperature is never-
theless regulated.WARNING■ Do not switch off the Climatronic system for longer than necessary.■Switch on the Climatronic system as soon as the windows mist up.Note■Do not stick anything onto or cover the interior temperature sensor B » Fig. 95
as this could impair the functioning of the Climatronic.■
On vehicles equipped with a factory-fitted radio or radio navigation system, the
Climatronic information is also shown on their displays. This function can be
switched off, see » operating instructions for the radio or navigation system .
Note
If the windscreen mists up, press the symbol button . Press the button
once the windscreen has demisted.
Using the air conditioning system economically
First read and observe the introductory information and safety warn-ings
on page 91.
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the inte-rior has been strongly heated through the effect of direct sunlight in order to al-
low the heated air to escape.
The cooling system should not be on if the windows are open.
If the desired interior temperature can be achieved without switching the cooling
system on, then we do not recommend turning this on.
For the sake of the environment
Pollutant emissions are also reduced when fuel is saved » page 130, Economical
driving and environmental sustainability .
96Using the system
Operational problemsFirst read and observe the introductory information and safety warn-
ings
on page 91.
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 236 .
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 11.
If you are not able to resolve the operational problem yourself, or if the cooler output has reduced, switch off the cooling system and seek assistance from a
specialist garage.
Auxiliary heating (auxiliary heating and ventilation)

Conditions for the functioning of auxiliary heating (Aux. heating and ventilation),
hereinafter referred to only as auxiliary heating (Aux. heating).
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon
is not lit in the display of the
instrument cluster).
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) can be used when stationary, when the engine is switched off to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
The auxiliary heating (auxiliary heating) also warms up the engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank.
The coolant warms up the air, which (if the blower speed is not set to zero) flows into the passenger compartment.WARNING■ The auxiliary heater (independent vehicle heater) must never be operated in
closed rooms (e.g. garages) – risk of poisoning!■
The auxiliary heating (parking heating) must not be allowed to run during re-
fuelling – risk of fire.
■
The exhaust pipe of the auxiliary heating is located underneath the vehicle.
Therefore, if you wish to operate the auxiliary heating (auxiliary heating), do
not park the vehicle in such a way that the exhaust gases can come into con-
tact with highly flammable materials (e.g. dry grass) or easily inflammable sub-
stances (e.g. spilt fuel) – risk of fire.
CAUTION
■ The running auxiliary heating (auxiliary heating) consumes fuel from the vehicle
tank and automatically controls the filling level. If only a low quantity of fuel is
present in the fuel tank, the auxiliary heater switches itself off.■
The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating is running, the vehicle battery discharges. If the auxiliary
heating and ventilation has been operated several times over a longer period, the
vehicle must be driven a few kilometres in order to recharge the vehicle battery.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating problem.
