Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The air inlet in front of the windscreen must be free of ice, snow or leaves
in order to ensure that the heating and cooling systems operate properly.
The AC compressor is switched off at a high coolant temperature in order
to provide cooling at a high load of the engine.
After switching on the cooling
Condensation from the evaporator of the
air conditioning may drip down and form a puddle below the vehicle. This
is quite normal and not an indication of a leak!
Recommended setting for all periods of the year:
•Set the temperature to 22 °C (72 °F).
•Press the button ⇒page 130, fig. 122 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly
upwards ⇒page 133, fig. 123 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 130, fig. 122 . The
information in the desired temperature measuring unit appears in the
display.
WARNING
•For your own safety and that of other road users, ensure that all
the windows are free of ice, snow and misting. Please familiarize
yourself about how to correctly operate the heating and ventilation
systems, how to demist and defrost the windows, as well as with
the cooling mode.
•You should not leave recirculated air mode on over a longer
period of time. “Stale air” may result in fatigue in the driver and
passengers, reduce attention levels and also cause the windows to
mist up. The risk of having an accident increases. Switch recircu-
lated air mode off as soon as the windows begin misting up.
Note
•If the cooling system has not been switched on for a lengthy period,
odours may be produced at the evaporator because of deposits. Switch
the cooling system on at least once a month for approximately 5 minutes
at the highest blower stage - also during the cold season of the year - in
order to remove such odours. Also open a window for a short time.
•We recommend that you do not smoke in the vehicle when the recir-
culating air mode is operating since the smoke which is drawn at the evap-
orator from the interior of the vehicle forms deposits in the evaporator of
the air conditioning system. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through
considerable effort and expense (replacement of compressor).
•The used air streams out through the air removal openings in the
luggage compartment.
•The Information of the Climatronic is displayed on the display of the
radio*. You can also switch off this function - see operating instructions for
radio

gers, reduce attention levels and also cause the windows to mist
up. The risk of having an accident increases. Switch recirculated
air mode off as soon as the windows begin misting up.
Note
If the windscreen mists up, press the button ⇒page 130, fig. 122 .
After the windscreen has been demisted, press the button .
Setting temperature
You can separate the interior temperature for the left and right
side separately.
– You can set the temperature for both sides after switching on the ignition with the control dial .
– If you wish to set the temperature for the right side, turn the control dial .
If the temperature for the right side was set via the control dial , it can
no longer be set via the control dial - temperature for both sides. This
is only possible if you press the button for about 2 seconds.
You can set the interior temperature between +16 °C (60 °F) and +29.5
°C (85 °F). The interior temperature is regulated automatically within this
range. If you select the temperature below +16 °C (60 °F), “LO” appears
in the display. If you select the temperature higher than +29.5 °C (85 °F),
“HI” appears in the display. In both limit positions the Climatronic operates
at maximum cooling or heating capacity, respectively. The temperature is
not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in partic-
ular at the leg area) and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of seven blower stages available.
The Climatronic system controls the blower stages automatically
in line with the interior temperature. You can also, however,
adapt the blower stages manually to suit your particular needs.

•The exhaust pipe of the auxiliary heating is located on the
underside of the vehicle. Therefore do not place the vehicle, if you
wish to operate the auxiliary heating, in such a way that the exhaust
gases of the auxiliary heating can come easily into contact with
inflammable materials (e.g. dry grass) or easily inflammable
substances (e.g. fuel run out).
Note
•If the auxiliary heating runs, the fuel consumption comes from the
vehicle tank. Therefore the auxiliary heating should not be operated, if
there is very little fuel in the tank.
•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 and ventilation 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 kilom-
eters in order to recharge the vehicle battery.
•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.
•After switching off the auxiliary heating, the coolant pump runs for a
short period.
•The auxiliary heating and ventilation does not switch on or comes on,
if the vehicle battery indicates a low loading state.
•The auxiliary heating (auxiliary heating) switches on, if in the informa-
tion display: Please refuel! is indicated or was indicated before switching
off the ignition.
•When driving, the auxiliary heating can only be switched on, if the exte-
rior temperature is lower than 5 °C.
•The air inlet in front of the windscreen must be free of ice, snow or
leaves in order to ensure that the auxiliary heating operates properly.
•So that the warm air can flow into the vehicle interior after switching on
the auxiliary heating (auxiliary heating), the control dial ⇒page 119,
fig. 116 must be turned up to the stop to the right when heating. With
Climatic and Climatronic, you can maintain the temperature normally
selected by you (we recommend 22 °C). It is recommended to put the air
flow in the position
. For heating and climatic put the blower switch
