els, series and optional equipment for your

WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
THERMATIC automatic climate control regu-
lates the temperature and the humidity in the
vehicle interior and filters undesirable sub-
stances from the air.
THERMATIC automatic climate control is only
operational when the engine is running. Opti-
mum operation is only achieved if you drive
with the side windows and sliding sunroof
closed.
The climatic comfor tdeteriorates whilst the
sliding sunroof is open. The automatic climate
control cannot maintain the set temperature
with the sliding sunroof open. You have to
adjust the climate control manually.
i The residual heat function can only be
activated or deactivated with the ignition
switched off.
i The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 133). i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 78). 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. Aclogged 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. 124

Information about Service Arduous operating conditions or increased
loads on the vehicle will require some service
work to be performed more often than for a
vehicle in normal use. Such arduous condi-
tions include regular city driving with frequent
intermediate stops and use in mountainous
terrai noronp oor road surfaces.
For example, if the vehicle is used under ardu-
ous operating conditions, have air filters,
engine oil and oil filters changed frequently
and check the wheels often.F urther informa-
tion can be obtained at a qualified specialist
workshop, e.g. a Mercedes-Ben zService
Centre. Fuel/water separator
H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. !
If you continue driving without having the
fuel/water separator serviced, this could
cause damage to the engine. Any resulting
damage is not covered by the warranty.
If the fuel/water separator needs servicing,
the following message appears in the multi-
function display: You will also hear a brief warning tone.
X
Visit a qualified specialist workshop as
soon as possible. Care
General notes
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly Care

Additives
!
Do not use any additives with the engine
oil. This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAEc lassification (viscosity). The table
shows you which SA Eclassifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regular oil
changes using an approved engine oil with the
appropriate SA Eclassification. Brake fluid

WARNING
Over a period of time, the brake fluid absorbs
moisture fro mthe air; This lowers its boiling
point. 346
