Instruments and Indicator/Warning Lights 16During the driving time and always before the engine has reached its operating
temperature, generally avoid high engine speeds ⇒page 163.
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 to a higher gear in good time helps to reduce the fuel consumption, mini-
mises operating noise levels, protects the environment and contributes to a longer
life and reliability of the engine.Coolant temperature gauge*The coolant temperature gauge ⇒page 15, fig. 18 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 temperature as soon as the pointer has
reached the mid-range of the scale*. The pointer may also move further to the right
at high engine loads and high outside temperatures. 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. Observe the guidelines
⇒page 29, “Coolant temperature/coolant level ”.
WARNING
Pay attention to the warning notes ⇒page 185, “Working in the engine
compartment” before opening the bonnet and inspecting the coolant level.
Caution
Additional headlights and other attached components 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 temperatures and high engine loads!Fuel gaugeThe fuel gauge ⇒page 15, fig. 18 only operates when the ignition is switched
on.
The fuel tank has a capacity of about 45 litres. The warning symbol in the instrument
cluster lights up when the pointer drops to the reserve marking
. There are now
about 7 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
A peep sounds as an additional 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.

Technical Data
Using the air conditioning system economicallyThe compressor on the Climatic uses power from the engine when in cooling mode
which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the inte-
rior has been strongly heated through the effect of direct sunlight in order to allow
the heated air to escape.
The cooling system should not be switched on while travelling when the window is
open.
The desired interior temperature can also be achieved without switching in the
cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.Operational problemsIf the cooling system does not operate at outside temperatures higher than +2 °C,
there is a problem in the system. The reasons for this may be:•
The fuse of the Climatic is defective. Check the fuse, replace it if necessary
⇒page 216.
•
The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot ⇒page 16.
If you are not able to rectify the operational problem yourself, or if the cooling
capacity decreases, switch the cooling system off. Contact a specialist garage.
If there is a fault at the Climatronic, all symbols on the display flash after switching
on the ignition for 15 seconds. Contact a specialist garage.
Climatronic (automatic air conditioning)*Description
The Climatronic system is a combination 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 automatically varying the temperature of the
outflowing air, the blower stages and the air distribution. The system also takes into
account sunlight which eliminates the need to alter the settings manually. The
automatic mode ⇒page 97 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 the 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.
