Air conditioning
130 General notes
The air-conditioning system*/
Thermotronic* controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances from the air.
Heatmatic/the air-conditioning system*/
Thermotronic* is only operational when the
engine is running. Optimum operation is ach-
ieved only when you drive with the side win-
dows and panorama louvred sliding sun-
roof* closed. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 86). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and completely filters out pol-
len. A clogged filter reduces the amount of
air supplied to the vehicle interior. For this
reason, you should always observe the interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may obstruct your view
of the traffic situation, thereby causing an
accident. Cont

Refuelling
170 Diesel (EN 590)
! Only use diesel that complies with the
EN 590 European standard.
You could otherwise impair engine output
or damage the engine.
You will find further information about die-
sel under "Fuel" in the index.
! When refuelling vehicles with a diesel par-
ticle filter in countries outside the EU, only
low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
should be used. In countries in which diesel
with a higher sulphur content is available
(e.g. 0.035 percent by weight), the engine
oil should be renewed at more frequent
intervals. More information about intervals
for changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.
! Using fuel that does not comply with
EN 590 can increase wear and damage the
engine and the exhaust system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel R
vegetable oil
R petrol
R paraffin
R kerosene
Do not add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers – see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the war-
ranty.
For further information on "Fuel" see
(Y page 292).
Lo w outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
To prevent operating problems, diesel fuel
with improved cold flow qualities is available
during the winter months. Your vehicle must
be refuelled with this winter diesel at temper-
atures of -5 °C or below.
You can use this winter diesel at tempera-
tures down to about -20 °C without problems.
If only summer diesel fuel or less cold-resist-
ant winter diesel fuel (e.g. in Mediterranean
regions) is available, you should add anamount of flow improver to the fuel corre-
sponding to the outside temperature.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage.
G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
Flow improver
The effectiveness of a flow improver is not
guaranteed with every fuel. Observe the infor-
mation provided by the manufacturer when
using a flow improver. Only use flow improv-
ers that have been tested and approved by
Mercedes-Benz. Information about flow
improvers that have been tested and
approved by Mercedes-Benz can be obtained
from any Mercedes-Benz Service Centre. Operation

There is insufficient brake fl uid in the
brake fluid reservoir. X
Pull over and stop the vehicle safely, paying
attention to road and traffic conditions. Do not
continue driving under any circumstances.
X Consult a qualified specialist workshop.
X Do not top up the brake fluid. This will not rec-
tify the fault. ! Release parking

Visit a qualified specialist workshop. D Coolant Stop car,
turn eng. off The coolant is too hot. X
Pull over and stop the vehicle safely and switch
off the engine, paying attention to road and
traffic conditions.
X Make sure, that the air supply to the radiator
is not blocked, e.g. by slush.
X Restart the engine only when the display mes-
sage disappears. Otherwise, there is a risk of
engine damage.
X Pay attention to the coolant temperature dis-
play.
X If the temperature increases again, visit a quali-
fied specialist workshop immediately. 27
