Caution
The needle of the revolutions counter must on no account move into the red zone
of the scale - risk of engine damage!
For the sake of the environment
Shifting up early helps yo u save fuel and reduce the operating noise of your
vehicle.
Coolant temperature gauge
The coolant temperature gauge ⇒page 10, fig. 2 operates only when the igni-
tion is switched on.
In order to avoid any damage to the engine , please pay attention to the following
notes regarding the temperature ranges:
Cold range
If the pointer is in the left-hand area of the scale it means that the engine has not
yet reached its operating temperature. Avoid running at high engine speeds, at full
throttle and at severe engine loads.
The operating range
The engine has reached its operating temp erature as soon as the pointer moves
into the mid-range of the scale. The pointe r may also move further to the right at
high engine loads and high outside temperat ures. This is not critical provided the
warning symbol
in the instrument cluster does not flash.
If the symbol
in the instrument cluster flashes it means that either the coolant
temperature is too high or the coolant level is too low. Please refer to the guide-
lines ⇒page 28, “Coolant temperature/ Coolant quantity ”.
WARNING
Pay attention to the warning notes ⇒page 210, “Working in the engine
compartment” before opening the bonnet and inspecting the coolant level.
Caution
Additional headlights and other attached co mponents in front of the fresh air inlet
impair the cooling efficiency of the coolant. There is then a risk of the engine over-
heating at high outside temper atures and high engine loads!
Fuel gauge
The fuel gauge ⇒page 10, fig. 2 only operates when the ignition is switched on.
The fuel tank has a capacity of about 55 li tres (on vehicles with four-wheel drive
approx. 60 litres). The warning symbol
in the instrument cl uster lights up when
the pointer reaches the reserve marking. There are now about 8 litres of fuel
remaining in the tank. This symbol is a reminder for you, that you must refuel.
The following will be displayed in the information display*: Please refuel! (Please refuel!)
A peep sounds as an ad ditional warning signal.
Caution
Never run the fuel tank completely empty! An irregular fuel supply can result in
poor ignition or misfiring. Unburnt fuel may get into the exhaust system and
damage the catalytic converter.
Speedometer
Warning against excessive speeds*
An acoustic warning signal will sound when the vehicle speed exceeds 120 kilome-
tres per hour. The acoustic warning signal will switch off again when the vehicle
speed goes below this speed limit.
Note
This function is only valid for some countries.

Heating and air conditioning system
108
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.
Operational problems
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be:
•The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary ⇒page 243.
•The cooling system has switched off auto matically for a short time because the
coolant temperature of the engine is too hot ⇒ page 11.
If you are not able to rectify the operat ional problem yourself, or if the cooling
capacity decreases, switch the cooling system off. Contact a specialist garage.
Climatronic* (automatic air conditioning)
Description
The Climatronic system is a combin ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the
occupants of the car.
The Climatronic maintains a constant temperature fully automatically, once it has
been set. This is achieved by automa tically varying the temperature of the
outflowing air, the blower stages and the air distribution. The system also takes into
account bright sunlight which eliminates the need to alter the settings manually.
The automatic mode ⇒ page 110 ensures maximum wellbeing of the occupants
at all times of the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
•engine running,
•outside temperature above +2 °C,
•the button is not pressed.
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this
particularly at high outside temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
The heating effect is dependent upon th e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculated air mode in order to enhance the
cooling effect ⇒.
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 condi-
tioning may drip down and form a puddle below the vehicle. This is quite normal
and not an indication of a leak!
Recommended setting for al l periods of the year:
•Set the temperature to 22 °C (72 °F).
•Press the button ⇒page 109, fig. 125 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards
⇒ page 112, fig. 126 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 109, fig. 125 . The informa-
tion 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 mist ing. Please familiarize yourself about
how to correctly operate the heating an d ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.
