Air conditioning
Overview of air-conditioning systems
The vehicle is equipped with one of the following air-conditioning systems: 2-zone Thermatic
Front control unit The 2-zone Thermatic automatic air condi-
tioning system combines an automatic heat-
ing and ventilation system with a cooling sys-
tem. You can control the temperature sepa-
rately for the driver's and front-passenger
sides. 3-zone Thermotronic*
Front control unit
Rear control panel The 3-zone Thermotronic automatic air con-
ditioning system combines an automatic
heating and ventilation system with a cooling
system. You can control the temperature
separately for the driver's and front-
passenger sides and the rear compartment.
You can control the airflow separately for the
front and rear compartments. You can con-
trol the air distribution separately for the
driver's and front-passenger sides. General notes
2-zone Thermatic/3-zone Thermotronic*
controls the temperature and the humidity of
the vehicle interior and filters out undesirable
substances from the air.
2-zone Thermatic/3-zone Thermotronic* is
only operational when the engine is
running. 24
Optimum operation is only ach-
ieved when you drive with the side windows
and panorama sliding sunroof* closed. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 82). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
24 3-zone Thermotronic*: the "residual heat" function can only be activated or deactivated if the ignition is turned off. Air conditioning

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. Otherwise, the windows could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident.

Instructions and recommendations for
optimum air conditioning:
R activate the air conditioning using
the à and¿ buttons. The indica-
tor lamps in the Ãand¿ buttons
come on.
R set the temperature to 22 †.
R only use the "demisting" function briefly,
until the windscreen is clear again.
R only use the "air-recirculation" mode
briefly, e.g. if there are unpleasant out-
side odours or when in a tunnel. Other- 118 Air conditioningControls

? Fuel type
X To open: press the fuel filler flap in the
direction of arrow :.
The fuel filler flap opens slightly.
X Open the fuel filler flap.
X Turn the fuel filler cap anti-clockwise and
remove it.
X Insert the fuel filler cap into the holder
bracket on the inside of filler flap ;.
X Only fill the tank until the pump nozzle
switches off.
! Overfilling the fuel tank could damage the
fuel system.
X To close: replace the fuel filler cap and turn
it clockwise. The fuel filler cap audibly
engages.
X Close the fuel filler flap.
i Vehicles with a diesel engine: if the fuel
tank has been run completely dry, it will be
necessary to bleed the fuel system
(Y page 206). Petrol (EN 228)
! Refuel using only unleaded premium
grade petrol with a minimum octane num-
ber of 95 RON/85 MON conforming to
European standard EN 228.
Otherwise, you could impair engine output
or damage the engine.
i As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the quality of the avail-
able petrol may not be adequate and could
cause coking around the inlet valve. In such
cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.

G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
would damage the fuel system and engine and
could result in a vehicle fire.
! Refuel using only diesel which conforms
to European standard EN 590 or German
standard DIN 51628.
Otherwise, you could impair engine output
or damage the engine.
! When refuelling vehicles with a diesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used. Refuelling

R
engine oil brand
R grade (MB Sheet number)
R SAE classification (viscosity)
is not available, you can use another min-
eral or synthetic engine oil which has been
approved by Mercedes-Benz. You must
then have an oil change carried out at the
earliest possible opportunity.
Mixing oils reduces the benefits of high-
grade engine oil.
! Do not use lubricant additives as they can
lead to increased wear and damage to
mechanical assemblies. The use of lubri-
cant additives will result in a restriction of
your warranty.
! Engine oils for vehicles without a diesel
particle filter may also be used temporarily
in vehicles with a diesel particle filter if the
engine oil listed is not available. You must
then have an oil change carried out as soon
as possible.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity, this means it is thick; a low viscosity means
that it is thin.
Select the SAE classification (viscosity) of the
engine oil according to the outside tempera-
ture. The following table shows you the vis-
cosity classes to be used depending on the
average air temperature. Capacities
The following values refer to an oil change
including the oil filter.

Coolant
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is
topped up with a coolant that will ensure adequate antifreeze and corrosion protec-
tion.
! Only top up with coolant that has been
premixed with the desired antifreeze pro-
tection. Otherwise, you could damage the
engine.

ing can be found in the Mercedes-Benz
