WARNING
•
If you must stop for technical reasons, then park the vehicle at a safe
distance from the traffic and switch off the engine and switch on the hazard
warning light system ⇒page 54.
•
The red oil pressure light
is not an oil level indicator! One should
therefore check the oil level at regular intervals, preferably after every refu-
eling stop.
•
Pay attention to the following instructions ⇒page 185, “Working in the
engine compartment” before checking the coolant fluid level and opening
the bonnet.
Open door*
The warning light
comes on if one or several doors, the bonnet or boot lid is
opened.
The warning light comes on even when the ignition is switched off. The warning
light goes out 5 minutes after switching off the ignition if one or several doors, the
bonnet or boot lid is opened. The warning light goes out after closing the doors.

REFILL WASHER LIQUID
Control system for exhaust
The warning light
comes on after the ignition has been switched on.
If the warning light does not go out after starting the engine or it lights up when
driving, a fault exists in an exhaust relevant component. The engine management
system selects an emergency programme which enables you to drive to the nearest
specialist garage by adopting a gentle style of driving.
The following text will be displayed in the information display*:
EXHAUST WORKSHOP!
Traction control system (TCS) *
The warning light
comes on for a few seconds when the ignition is switched on.
The warning light flashes when a control cycle is activated while driving.
The warning light will come on and remains on if the TCS is switched off or if there
is a fault in the system.
The fact that the TCS system operates together with the ABS means that the TCS
warning light will also come on if the ABS system is not operating properly.
If the warning light comes on immediately after starting the engine, the TCS
system can be switched off for technical reasons. In this case, the TCS system can
be switched on again by switching the ignition on and off. If the warning light goes
out, the TCS system is fully functional again.
Further information about the TCS ⇒page 156.
Note
If the battery has been disconnected and reconnected, the warning light
comes
on after switching on the ignition. The warning light must go out after driving a short
distance.

Pay attention to the following instructions before checking the brake
fluid level and opening the bonnet ⇒page 185, “Working in the engine
compartment”.
•
If the brake fluid is at the correct level, the ABS control function has
failed. The rear wheels may then block very rapidly when braking. In certain
circumstances, this can result in the rear end of the car breaking away - risk
of skidding! Drive carefully to the nearest specialist garage and have the
fault rectified.

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.

Heating and air conditioning system 96After 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 all periods of the year:•
Set the temperature to 22 °C.
•
Press the button ⇒fig. 121.
•
Move the air outlet vents 3 and 4, so that the air flow is directed slightly
upwards.
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒fig. 121. 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, as “stale” air may result in fatigue in the driver and occupants, divert
your attention 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 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 recirculating air
mode is operating since the smoke which is drawn at the evaporator from the inte-
rior 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 (replace-
ment of compressor).
•
The used air streams out through the air removal openings in the luggage
compartment.

Heating and air conditioning system 98Setting temperature– You can set the desired interior temperature after switching on the
ignition with the control dial .You can set the interior temperature between +18°C and +29 °C. The interior
temperature is regulated automatically within this range. If you select a tempera-
ture of less than +18 °C, “LO” is shown on the display. If you select a temperature
above +29 °C, “HI” is shown on 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 particular 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.
– Turn the control dial ⇒page 96, fig. 121 to the left (reduce blower
speed) or right (increase blower speed).If you switch off the blowers, the Climatronic is switched off and OFF is shown in
the display.
The set blower speed is displayed next to the control dial when the respective
number of warning lights come on.
WARNING
•
“Stale air” may result 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.
•
Do not switch the Climatronic system off for longer than necessary.
•
Switch the Climatronic system on as soon as the windows mist up.
