• The interior temperature can be freely selected with buttons17
and 18and is stored permanently until another temperature is
selected.
The interior temperature can be set between +18°C (64°F) and
+29°C (86°F). In this range it is automatically regulated.
If temperatures below +18°C (64°F) are selected “LO” appears in
the display. With temperatures above +29°C (86°F) “HI” is
displayed.
In these two end positions the system works continuously at
maximum cooling or heating output. The temperature is not
regulated.• If the blower speed is changed up or down a stage, automatic
mode is still retained.
• In certain operating conditions it may be found that the system
temporarily carries out functions which are not quite as expected.
This includes, for example, that for a few seconds after starting
from cold, air is directed mainly into the footwell. This is intentional
so that damp air in the system does not cause the windows to mist
up.

Partial deviation from Automatic mode
In nearly all cases the Automatic mode offers the best conditions
for the comfort of the vehicle occupants all the year round.
In isolated cases however it can be necessary to move away form
certain functions of the automatic mode by pressing various
buttons. The Climatronicstill works automatically.
The blower speed and thus the air volume at the front can be
increased or reduced with buttons
13and 14. This is shown by a
change in the number of lines in display position 1.
• By pressing button
11
– the ECON operation is switched off
– the air recirculation mode is switched off
– the windscreen and side windows can be defrosted or kept free
of misting (direct vents
4onto side windows)
– the dehumidifying and defrosting effect for the windscreen can
be increased if, for example persons with damp clothing are picked
up shortly after moving off.

for the front is selected by pressing button
12.
The symbol5appears in the display.
The air recirculation function prevents strong outside smells
entering the vehicle, for example when driving through a tunnelor
standing in a trafficjam.Air recirculation can also be selected if the vehicle is to be heated
or cooled quickly. In this mode, air is drawn in from the vehicle
interior and heated or cooled.
Smoking should be avoided when air recirculation is selected, as
the smoke drawn in from the vehicle interior deposits on the
evaporator of the Climatronic. This leads to permanent odours
when the Climatronicis in operation. These can only be eliminated
by exchanging the evaporator, which is time-consuming and
expensive.
• With buttons
15and 16the air flow can be to the upper part of
the body or into the footwell.
• The combination of buttons
11and 16can be used to direct the
air flow both to the windscreen and into the footwell.

unburnt fuel into the exhaust system, which can cause overheating and
damage to the catalyst.

Releasing tank flap manually
If the central locking system should fail, the flap can be released
manually:

compartment trim from side panel.
• Then push the locking rod in front of the white diaphragm
housing backward slightly in direction of arrow

General notes
•Unleaded petrol must comply with DIN EN1)228 and leaded
petrol with DIN 51 600.
•If, in an emergency, the octane rating of the available petrol is

engine speeds and low engine loading. H Hi

Driving in winter
When using summer Diesel trouble may be experienced at
temperatures below 0 °C because the fuel thickens due to wax
separation.
For this reason winter Diesel which is more resistant to cold is sold
during the winter in some countries, and this works correctly down
to between –15 °C and –22 °C approximately, depending on the
brand of fuel used.
The biodiesel available in countries with different climactic
conditions usually has different temperature characteristics.
Technical Service Centres or service stations in each country can
inform you of the specific characteristics of the respective diesel.
K
Filter preheating
The vehicle is fitted with a filter preheater. This will ensure that the
fuel system will remain operational down to about –25 °C,
provided that winter Diesel which is cold resistant down to –15 °C
is used.
If, at temperatures below –25 °C the fuel is waxed to such an
extent that the engine will not start it is sufficient to place the
vehicle in a warm enclosure for a while.

•On vehicles with a rev counter* the maximum permissible engine

is of great importance for the environment-friendly functioning of
your vehicle.
Therefore, keep in mind the following points:
•Versions with a catalytic converter must only use unleaded fuel
⇒"Filling the tank" chapter.
•In vehicles with a catalytic converter never drive until the fuel
tank is completely empty. Irregular fuel supply can cause misfiring,
thus allowing unburned fuel into the exhaust system which can
cause overheating and damage to the catalyst.
•If you experience starting difficulties, loss of power or engine
problems while driving, the cause could be a failure in the ignition.In this case, fuel may be entering the exhaust system without
burning and, in this way being released into the atmosphere.
Furthermore, the catalyst could deteriorate due to overheating.
Reduce speed immediately. Have this problem fixed at the nearest
Technical Service Centre.
•Do not overload the engine with oil
⇒"Engine oil" chapter.
•Do not towstartthe vehicle for more than 50 m
⇒"Tow
start/towing" chapter.
N No
ot
te
e
Even when the cleaning system for exhaust fumes is in perfect working
order, under certain circumstances, the fumes may smell like sulfur.
This depends on the percentage of sulfur in the fuel.
Often it is sufficient to change brands or buy super unleaded.
