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 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

or cannot easily be turned into this position, in order to release the
steering lock.
Position
The engine is started in this position. At the same time switched on low
beam or main beam or other electrical components with major power
consumption are briefly switched off. The ignition key moves back into
position when one releases the key.
The ignition key must be turned back into position each time before
starting the engine again. The starter repeat lock in the ignition lock
prevents the starter being engaged when the engine is running and thus
getting damaged.

Starting-off and Driving141
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Petrol engines
These engines are fitted with a starter system which selects the correct
fuel/air mixture for every external air temperature.
•Do not operate accelerator before and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 288.
•Contact the nearest specialist garage to obtain professional assist-
ance.
It may be necessary, if the engine is very hot, to slightly depress the
accelerator after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period
being controlled automatically in line with the coolant temperature and
outside temperature.
The preglow indicator light
 comes on after the ignition has been
switched on.
You should not switch on any major electrical components during
the heating period otherwise the ve hicle battery will be drained
unnecessarily.
•You should start the engine immediately after the glow plug warning
light  has gone out.
•The glow plug warning light will come on for about one second if the
engine is at a normal operating temperature or if the outside temperature
is above +5°C. This means that you can start the engine right away.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the diesel preglow system is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 288.
•Contact the nearest specialist garage to obtain professional assist-
ance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel
tank has run completely dry - up to one minute. This is because the fuel
system must first of all be filled while the attempting to start the engine.
Switching the engine off
– The engine can be switched off by turning the ignition key from position ⇒page 139, fig. 129 into position .
WARNING
•Never switch off the engine before the vehicle is stationary - risk
of accident!
•The brake booster only operates when the engine is running.
Greater physical effort for braking is required when engine is
switched off. Because if you do not stop as normal, this can cause
an accident and severe injuries.
