Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only briefly
R switch on the cooling with air dehumidifica-
tion function
R switch on the defrost windshield function
briefly, if required
The dual-zone automatic climate control regu-
lates the temperature and the humidity in the
vehicle interior and filters undesirable substan-
ces out of the air.
Dual-zone automatic climate control is only
operational when the vehicle is ready to drive.
Optimum operation is only achieved with the
side windows closed.
Always keep the ventilation flaps behind the
side paneling in the cargo compartment clear.
Otherwise the vehicle will not be ventilated cor- rectly. i
Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 76). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odors. 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 Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.
i It is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-tilated for 30 minutes. Control panel for dual-zone automatic climate control

Information about Service
Resetting the ASSYST PLUS service
interval display !
If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at a qualified specialist work-
shop.
Have service work carried out as described in the Maintenance Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
A qualified specialist workshop, e.g. an author-
ized Mercedes-Benz Center, will reset the
ASSYST PLUS service interval display after the
service work has been carried out. You can also obtain further information on maintenance
work, for example.
Special service requirements The specified maintenance interval takes only
the normal operation of the vehicle into
account. Service work will need to be performed
more often if the vehicle is operated under ardu-
ous conditions or increased loads. This can be
the case, for example, when driving frequently in mountainous areas or on poor road surfaces.
In these or similar operating conditions have the interior filter, for example, changed more fre-
quently. Under arduous operating conditions,
the tires must be checked more often. Further
information can be obtained at a qualified spe-
cialist workshop, e.g. an authorized Mercedes-
Benz Center.
Driving abroad An extensive Mercedes-Benz Service network is
also available in other countries. You can obtain further information from any authorized
Mercedes-Benz Center. Care

Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man- ner. !
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.
! Do not park your vehicle for a long period of
time directly after cleaning, particularly after
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for a few minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a long period of time.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents recom-
mended and approved by Mercedes-Benz. Washing the vehicle and cleaning the
