Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 25). Overview of climate control systems

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.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 150).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 96). 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.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30minutes to dry
the air-conditioning system. 142

Information abou
tService Resetting the ASSYST PLUS service inter-
val display
!
If the ASSYST PLUS service interval dis-
play has been inadvertently reset, this set-
ting can be corrected at a qualified special-
ist workshop.
Have service work carried out as described
in the Service Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
Aq ualified specialist workshop, e.g. a
Mercedes-Ben zService Centre, will reset the
ASSYST PLUS service interval display after
the service work has been carried out. You
can also obtain further information on main-
tenance work, for example.
Special service requirements
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
terrain or on poor 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 chec kthe wheels often.F urther informa-
tion can be obtained at a qualified specialist
workshop, e.g. a Mercedes-Ben zService
Centre.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's curren ttelephone numbers
for use when you are abroad are to be found
in the "Mercedes-Benz Service24h" section
of the Service Booklet. AdBlue

. AdBlue ®
is topped
up as part of the service. Under normal oper-
ating conditions, a full tank of AdBlue ®

last until the nexts ervice due date.
Depending on how and where the vehicle is
used, there may be an increase in the
AdBlue ®
consumption, resulting in the next
service due date being brought forward.
Certain display messages show that
AdBlue ®

You can no longer start the engine when the
AdBlue ®
supply has been used up
(Y page 281).
! Have the AdBlue ®
tank topped up at a
qualified specialist workshop only. The
vehicle may otherwise be damaged or
soiled.
Before taking a trip with your vehicle outside
Europe, have the AdBlue ®
supply checked at
a qualified specialist workshop. If necessary,
have AdBlue ®
topped up. Before a longer stay
outside of Europe, consult a qualified special-
ist workshop.
Observe the notes on AdBlue ®
(Y page 440).
