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.
iRead the information on qualified special-
ist workshops (
Ypage 25).
Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only
briefly
Rswitch on the cooling with air dehumidifi-
cation function
Rswitch 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 (
Ypage 169). The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Ypage 141).
Always keep the ventilation flaps behind the
side trim panel in the cargo compartment
clear (
Ypage 123). Otherwise the vehicle will
not be ventilated correctly.
iVentilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (
Ypage 89). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
iThe 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
Maintenance Booklet.
iIt 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.

Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
RSwitch on the air-conditioning system by
turning control knob Aclockwise to the
desired position (except position 0).
RSet the temperature to 72 ‡ (22 †).
RRecommendation for avoiding misted
windows at low exterior temperatures
or in rain:switch on the ¿cooling with
dehumidification function (
Ypage 136).
Set air distribution to ¯and if possible
switch off PandO (
Ypage 138).
Deactivate air-recirculation mode e
(
Ypage 141).
Set airflow control Ato a setting between
3 and 6(
Ypage 138).
RRecommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3
and 6(
Ypage 138).
RRecommendation for a constant vehi-
cle interior temperature: set airflow con-
trol Ato a setting between 1and 3
(
Ypage 138).
RRecommendation for air distribution in winter: select the Oand¯ settings
(
Ypage 138).
Recommendation for air distribution in
summer: select the PorP and
¯ settings (
Ypage 138).
ROnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outsid e od
ors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RIf 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
(
Ypage 155).
If you have selected drive program E:
Rwhen heating, the electrical heater booster
is deactivated and in the warming-up phase
heat output is reduced
Rthe 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 Cor 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 (
Ypage 153).

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 Mis
permanently activated, kickdown is not pos-
sible.
For further information on kickdown in man-
ual drive program M(

Rocking the vehicle free
Shifting the transmission repeatedly between
gears Dand Rmay 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 Dand R,
move the DIRECT SELECT lever up and down
past the point of resistance.
