Heating and air conditioning system 129
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

Recirculated air mode
In recirculated air mode air is sucked out of the interior of
the vehicle and then fed back into the interior.
Recirculated air mode prevents polluted air outside the vehicle
from getting into the vehicle, for example when driving through a
tunnel or when standing in a traffic jam.
Switching recircul ated air mode on
– Press the button - the warning light lights up in the button.
Switching recirculat ed air mode off
– Press again the button or the button - the warning light in the button goes out.
WARNING
You should not leave recirculated air mode on over a longer period
of time. “Stale air” may result in fatigue in the driver and passen-
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.

WARNING
•When driving, the ignition key mu st always be in the ignition
lock in the position (ignition switched on) without the engine
running. This position is indicate d by the warning lights coming on.
If this is not the case, it could result in unexpected locking of the
steering wheel - risk of accident!
•Only remove the ignition key from the ignition lock when the
vehicle has come to a standstill (put on the handbrake or select the
selector lever position P). The steering lock might otherwise
engage unintentionally - risk of accident!
•Always withdraw the ignition key if you are going to leave the
vehicle, even for a short time. This is particularly important if chil-
dren are left in the vehicle. The children might otherwise start the
engine or switch on electrical equipment (e.g. power windows) -
risk of accident or injury!
Starting engine
General
You can only start the engine only using an original ignition
key.
•Place the gearshift lever into neutral (or place the selector lever to the
position P or N in the case of an automatic gearbox) and put on the hand-
brake firmly before starting the engine.
•The clutch pedal should be fully depressed when starting the engine
which means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be
damage to the starter. The engine running noises may at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic
valve clearance compensation. This is quite normal and is not an oper-
ating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid
⇒page 281.
It is only possible to tow-start vehicles fitted with a manual gearbox. The
tow-starting distance must not be more than 50 metres ⇒page 286.
WARNING
•Never run the engine in non ventilated or enclosed areas. The
exhaust gases of the engine contain besides the odorless and
colourless carbon monoxide a poisonous gas - hazard! Carbon
monoxide can cause unconsciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the
engine is not running. If the starter is immediately operated after switching
off the engine, the starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as
long as the engine has not yet reached its normal operating temperature
- risk of damaging the engine!
•Vehicles which are fitted with an exhaust gas catalytic converter
should not be tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right
away. Through this the engine reaches its operating temperature more
rapidly and the pollutant emissions are lower.

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.

Caution
you should not switch the engine off right away at the end of your journey
after the engine has been operated for a lengthy period at high loads but
should be allowed it to run at idling speed for about 2 minutes. This
prevents any accumulation of heat when the engine is switched off.
Note
•The radiator fan may continue running for a further 10 minutes or so
after the engine and the ignition have been switched off. The coolant fan
may, however, also switch on again after some time if the coolant temper-
ature rises because of an accumulation of heat in the engine or if the
engine is warm and the engine compartment is additionally heated by
strong sunlight.
•This is why particular care is required when carrying out any work in
the engine compartment ⇒page 248, “Working in the engine
compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal
and hold it fully depressed. Wait a moment before engaging reverse gear
in order to avoid any shift noises.
The reversing lights will come on once reverse gear is engaged, provided
the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•One should not lay the hand on the shift lever while driving the vehicle.
The pressure of the hand will be transferred to the gearshift forks in the
gearbox. This can, over a period of time, lead to early wear of the gearshift
forks.
