Overview of the climat
econtrol sys-
tem General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R activate the "Cooling with dehumidification"
function
R activate the "Windscreen demisting" function
briefly, if required
Climate control regu lates the temperature and
the humidity in the vehicle interior and filters
undesirables ubstances out of the air. The "Cooling with air dehumidification" function
is available only when the engin eisrunning.
Optimum operation is only achieved when the
side windows and the sliding sunroof are closed.
Climate comfor tmay be adversely affected if the
sliding sunroof is open for along period of time.
Set the temperature manually if the sliding sun-
roof is open.
The "Residual heat" function can be switched on or off only when the ignition is switched off
(Y page 89).
The integrated filter can filter out most particles of dust and completely filters out pollen. Aclog-
ged filter reduces the amount of air supplied to
the vehicle interior. Dependin gonthe operating
conditions and environmental influences, the
interval for replacing the filter may be shorter
than specified. Control panel for THERMATIC automatic climate control (dual-zone)

WARNING
If yo umix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel .When the engine is running,
components in the exhaust system may over-
heatu nnoticed. There is arisk of fire.
Never refue lwith petrol. Never add petrol to
diesel fuel.
! Do not use petrol to refue
lvehicles with a
diesel engine. Do not switch on the ignitio nif
you accidentally refue lwith the wrong fuel.
Otherwise, fuel can enter the fuel system.
Even smal lamounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high .Notify a
qualified specialist worksho pand have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank coul
ddamage the
fuel system.
! Take care not to spil
lany fuel on painted
surfaces. You coul dotherwise damage the
paintwork.
! Use
afilter when adding fuel from afuel can.
The fuel lines and/or the fuel injection system coul dotherwise be blocked by particles from
the fuel can.
If you overfil lthe fuel tank, some fuel may spray
out when you remove the fuel pump nozzle.

The following cause engine failure or damage
to the exhaust system:
R Use of engine oils and oil filters that have
not been expressly approved for the service
system
R Replacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
R Use of engine oil additives
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick ,too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter .Have excess oil siphoned off. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of engine oil required.
Observe the specification sinthe on-board com-
puter when doing so or fill carefully to the max- imum mark on the oil dipstick.
The differenc ebetween the minimum mark and
the maximum mark on the oil dipstick is approx- imately 2.0 litres.
X Replace cap :on the filler neck and turn
clockwise.
Make sure that the cap locks securely into
place.

Important safety notes G
WARNING
Certain components in the engin ecompart-
ment coul dbevery hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is arisk of injury when accessing the
engine compartment.
As far as possible,a llow the engine to cool
downa nd only touch the components descri-
bed in the following. G
WARNING
There are moving components in the engine
compartment. Certain components may con-
tinue to move or suddenly move again even
after the ignitio nhas been switched off, e.g.
the radiator fan. There is arisk of injury.
If you have to carry out work in the engine
compartment:
R switch off the ignition
R never touch the dangerous area ssurround-
ing moving components, e.g. the rotation
area of the fan
R remove jewellery and watches
R keep items of clothing and hair, for exam-
ple,a wayfrom moving parts. G

mal operation of the vehicle. Servic ework will
need to be performed more often if the vehicle is operated under arduous conditions or increased
loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further information can be obtained at aqualified specialist work-
shop, e.g. aMercedes-Benz Servic eCentre. Fuel/water separator

This could damage the engine. Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to aheavy load. This would impair brak-
ing efficiency. There is arisk of an accident.
Have the brake flui drenewe datthe prescri-
bed intervals.
Comply with the important safety notes for ser- vice products when handling brake fluid
(Y page2 50).
Only use brake flui dapproved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.
Information about approved brake flui dcan be
obtained at any qualified specialist worksho por
on the Internet at
http://bevo.mercedes-benz.com.

Im portant safety notes G
WARNING
If antifreeze come sinto contact with hot com-
ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool downb efore you top up
the antifreeze .Make sure that antifreeze is
not spilled next to the filler neck. Thoroughly
clea nthe antifreeze from components before
starting the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
coul dotherwise damage the engine.
Further information on coolants can be found in the Mercedes-Benz Specifications for Ser-
vice Products, MB Specifications for Service
Products 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com .Orcontact

! Always use
asuitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosio nand
overheating.
i Have the coolant regularl

ment confirmed in the service report.
Comply with the important safety notes for ser- vice products when handling coolant
(Y page2 50).
The coolant is amixture of water and anti-
freeze/anti-corrosion additive. It is responsible
for the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosio ninhibitor is present in the
correct concentration, the boiling point of the
coolant willbea round 130 †. Service products and capacities
