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
It is necessary to disconnect both cables before charging the battery with high
amperages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 228, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Replacing
First read and observe the introductory information and safety warn-
ings
on page 207.
The new vehicle battery must have the same capacity, voltage, current and the
same size as the original Battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.
Disconnecting and reconnecting
First read and observe the introductory information and safety warn-
ings
on page 207.
On disconnecting and reconnecting the vehicle battery, the following functions
are initially deactivated or are no longer able to operate fault-free.
OperationOperating measureElectrical power window (operational faults)» page 44Panoramic sliding roof (operational faults)» page 234Enter the radio/navigation system code num-
ber» User manual of the radio
or » user manual of the naviga-
tion systemSetting the clock» page 13Data in the multifunction display are deleted.» page 25
Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 207.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This manifests itself by the
following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event
of an emergency.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle battery may be drained. For example, when the ignition is switched on a long
time with the engine turned off or the side or parking lights are turned on during longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle bat-
tery to discharge when the ignition is switched off.
