Instruments and Indicator/Warning Lights10
Avoid high engine speeds during the driving time and always if the engine has not yet reached its operating temperature ⇒page 159.
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 9, fig. 2 operates only when the ignition 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 moves into 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 24, “Coolant temperature/coolant level ”.
WARNING
Pay attention to the warning notes ⇒page 181, “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 gauge
The fuel gauge ⇒page 9, fig. 2 only operates when the ignition is switched on.
The fuel tank has a capacity of about 45 litres. The warning symbol in the instru-ment cluster lights up when the pointer reaches 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.

Close air outlet vents
– Turn the rotary knob into the lower position.
Redirecting air flow
– The horizontal as well as the vertical direction of the air flow is set with
the handle in the middle of the air outlet vents.
You can set the air supply to the individual vents with the air distribution control ⇒page 86, fig. 107. Air outlet vents 3 and 4 can also be opened or closed individ-ually:
Unwarmed or cooled air will flow out of the air outlet vents according to the setting of control dial ⇒page 86, fig. 107 and the atmospheric conditions.
Using the air conditioning system economically
The 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 problems
If 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 213.
•The cooling system has switched off automatically for a short time because the coolant temperature of the engine is too hot ⇒page 10.
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 91 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.
