Useful information
i This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops ( Y
page 25).
Overview of climate control systems
General notesObserve the settings recommended on the
following pages. The windows could other-
wise 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 dehumidifi-
cation function R
switch on the defrost windshield function
briefly, if required
The air-conditioning system/dual-zone auto-
matic climate control regulates the tempera-
ture and the humidity of the vehicle interior
and filters out undesirable substances from
the air.
The air-conditioning system/dual-zone auto-
matic climate control can only be operated
when the engine is running. Optimum opera-
tion is only achieved with the side windows
and panorama roof with power tilt/sliding
panel closed.
If you start the engine using your smartphone,
the last selected climate control setting is
reactivated ( Y
page 171). The residual heat function can only be acti-
vated or deactivated with the ignition
switched off ( Y
page 143).
Always keep the ventilation flaps behind the
side trim panel in the cargo compartment
clear ( Y
page 124). Otherwise the vehicle will
not be ventilated correctly.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature ( Y
page 91). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants 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 t he
Main tenance Booklet.
i It is possible that under certain circum-
stances the residual heat function may be
activated automatically an hour after the
SmartKey has been removed in order to dry
the automatic climate control. The vehicle
is then ventilated for 30 minutes.132
Overview of climate control systems
Climate control

R
Use the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac-
tivated with the ignition switched off. R
If you change the settings of the climate
control system, the climate status display
appears for approximately three seconds
at the bottom of the screen in the Audio/
COMAND display (see separate operating
instructions). You will see the current set-
tings of the various climate control func-
tions.
DYNAMIC SELECT button (except
Mercedes-AMG vehicles) You can choose between various drive pro-
grams with the DYNAMIC SELECT button
( Y
page 157).
If you have selected drive program E :R
when heating, the electrical heater booster
is deactivated and in the warming-up phase
heat output is reduced R
the rear window defroster running time is
reduced
Depending on the configuration, the climate
settings can also be influenced in drive pro-
gram I .
If you have selected drive program C or S , the
climate settings are not affected.
ECO start/stop function
During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button ( Y
page 155). Operating the climate control sys-
tems
Activating/deactivating the climate
control
General notes When the climate control is switched off, the
air supply and air circulation are also
switched off. The windows could fog up.
Therefore, switch off climate control only
briefly
Air-conditioning system X
Turn the SmartKey to position 2 in the igni-
tion lock ( Y
page 149). X
To switch on: turn control

Mercedes-AMG vehicles: it is only possible
to use kickdown in the automatic drive pro-
gram and the temporary manual drive pro-
gram M . When manual drive program M is
permanently activated, kickdown is not pos-
sible.
For further information on kickdown in man-
ual drive program M ( Y
page 168).
Rocking the vehicle free Shifting the transmission repeatedly between
gears D and R may help to free the vehicle if it
has become stuck in slush or snow. The vehi-
cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when
shifting back and forth. To shift back and forth
between transmission positions D and R ,
move the DIRECT SELECT lever up and down
past the point of resistance.
Drive programs
All vehicles (except Mercedes-AMG
vehicles)
Drive program C (Comfort)
Drive program C is characterized by the fol-
lowing: R
the vehicle delivers comfortable, economi-
cal handling characteristics. R
the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully. R
the vehicle having improved driving stabil-
ity, for example on slippery road surfaces. R
optimal fuel consumption resulting from
the automatic transmission shifting up
sooner. The vehicle is driven in the low
engine speed range and the wheels are less
likely to spin. Drive program S (Sport)
Drive program S is characterized by the fol-
lowing: R
sporty engine settings. R
the automatic transmission shifting up
later. the fuel consumption possibly being
higher as a result of the later automatic
transmission shift points.
Drive program I (Individual)
In drive program I the following properties of
the drive program can be selected: R
the drive (engine and transmission man-
agement) R
the steering R
the availability of the ECO start/stop func-
tion R
the climate control:
Information about the configuration of drive
program I with COMAND or Audio 20 can be
found in the Digital Operator's Manual.
i To permanently select the gears in drive
program I using the steering wheel paddle
shifters, select the M (manual) setting for
the drive.
Off-road drive program
The Off-road drive program is characterized
by the following: R
the vehicle exhibits optimal driving charac-
teristics on easily negotiable off-road ter-
rain.
Drive program E (Economy)
Drive program E is characterized by the fol-
lowing: R
comfort-oriented engine settings. R
optimal fuel consumption resulting from
the automatic transmission shifting up
sooner. R
the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully.164
