The tachometer
1
» Fig. 22 on page 28 shows the actual engine speed per
minute.
The beginning of the red scale range of the tachometer indicates the maxi-
mum permitted engine speed of a driven-in and operating warm engine.
You should shift into the next highest gear before the red scale of the revolu- tion counter is reached, or select mode D on the automatic gearbox.
The gear recommendation is important to note in order to maintain the opti-
mum engine speed » page 41.
CAUTION
The pointer of the tachometer must reach the red area for only a short time -
there is a risk of engine damage!

Read and observe on page 28 first.
The display » Fig. 24 provides information on the engine coolant temperature.
The fuel gauge only works if the ignition is switched on.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine has not yet reached its operating temperature. Avoid high speeds, full throttle
and high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale

High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too
high.
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.

Heating and manual air conditioning
113
Climatronic (automatic air conditioning)
114
Climatronic - automatic operation
115
Air distribution control
115
Air outlet vents
116
The heating and air conditioning ventilate and heat the vehicle interior. The air
conditioning system also cools and dehumidifies the vehicle interior.
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
The cooling system operates only if the following conditions are met. The cooling system is switched on.
The engine is running.
The outside temperature is above approx. +2 °C.
The blower is switched on.
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The cooling system prevents the windows from misting up during
the cold season of the year.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect » page 115 .
Health protection
To reduce health risks (e.g. common colds), the following instructions for the
use of the cooling system are to be observed. ▶ The difference between the indoor temperature and the outdoor air temper-
ature should not be greater than about 5 ° C.
▶ The cooling system is to be turned off about 10 minutes before the end of
the journey.
▶ Once a year, disinfection of the manual air conditioner or the Climatronic is to
be carried out by a specialist company. 
112Using the system

WARNING■For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. The blower should always be on to
prevent the windows from misting up.■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
CAUTION
■ The air inlet in front of the windscreen must be free of e.g. ice, snow or
leaves to ensure that the heating and cooling system operates properly.■
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 not a
leak!
■
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.

» page 112 .
The warning light below the button 
» Fig. 136 illuminates after activation,
even if not all of the conditions for the function of the cooling system have

Setting temperature
The temperature can be adjusted on the Climatronic control unit or in the Info-
tainment » Owner´s Manual Infotainment , chapter Setting the heating and the
cooling system .
The temperature can be set between +16 °C and +29.5 °C. The temperature is
regulated automatically within this range.

CAUTION
Do not cover the interior temperature sensor B » Fig. 137 as this could impair
the functioning of the Climatronic.
Note
■ During operation of the Climatronic, an increase in engine idle speed can oc-
cur under certain circumstances in order to ensure adequate heating comfort.■

is switched on. The
air flow to the windows will remain switched on after turning 
off.

Climatronic - automatic operation
Read and observe
and on page 113 first.
The automatic mode is used in order to maintain a constant temperature and
to demist the windows in the interior of the car.
Automatic mode can be switched off by pressing one of the buttons for the air
distribution or by increasing/decreasing the blower speed. The temperature
regulation is continued.
Operating modes
Automatic mode works in three modes - moderate, medium, and intensive.
Setting the individual operating modes » Owner´s Manual Infotainment , chap-
ter Setting the heating and the cooling system .
After the automatic mode is switched on, Climatronic works in the last selec-
ted mode.
The currently selected mode is displayed in the Infotainment display.
Note
Climatronic is set to the medium setting at the factory.
Air distribution control
Read and observe
and on page 113 first.
The recirculation mode prevents contaminated outside air getting into the In-
terior of the vehicle.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior.
Switching on/off
›
Press the  button.
When the recirculation mode is activated, the warning light below the button
lights up.
Heating and manual air conditioning system
If the air distribution control is set to position  when the recirculation modes
is switched on, the recirculated-air mode is switched off. Recirculated air mode
can be switched on again from this setting by repeatedly pressing the symbol
button .
When the  is switched on and the temperature regulator is turned to the
left, the recirculated-air mode is switched on.
Climatronic
Climatronic may have an air quality sensor for the detection of the pollutant
concentration in the sucked-in air.
If a considerable increase in concentration of pollutants is recognised by the
air quality sensor, the recirculated air mode will be switched on automatically.
When the pollutant concentration decreases to the normal level, the recircula-
ted air mode is automatically switched off. 
115Heating and ventilation

This automatic on/off switching of the recirculated-air mode can be activated
or deactivated in the Infotainment » Owner´s Manual Infotainment , chap-
ter Setting the heating and the cooling system .
If the button 
is pressed when the recirculation modes is switched on, the
recirculated-air mode is switched off.
Depending on the moisture conditions in the vehicle interior the air recircula- tion may also shut-down automatically.WARNINGThe recirculation system cannot be switched on for a longer period of time,
because there is no supply of fresh air from the outside. “Stale air” may re-
sult in fatigue in the driver and occupants, reduce attention levels and also
cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.
CAUTION
We recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from inside the vehicle is deposited on the
evaporator of the air conditioner. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through con-
siderable effort and expense (replacement of compressor).
Note
The automatic activation/deactivation of the air recirculation with Climatronic
only works if the outside temperature is higher than approx. 2 °C.Air outlet ventsFig. 138

116Using the system

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 operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux.
heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in open. It is recom-
mended to put the air flow in the position 
or 
