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:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The "Cooling with air dehumidification" function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 131).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 89). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly. If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 137).
iThe 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.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
iVehicles with ionization of the interior
air and air filter: in addition to ionization, the
vehicle has an air filter with anti-allergenic
properties that contribute to improved air fil-
tration.
iIt 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.
iPlug-in hybrid vehicles: observe the notes
on climate control in the separate Operator's
Manual.
122Overview of climate control systems
Climate control

Optimum use of automatic climate
control
The following contains notes and recommenda-
tions on optimum use of the dual-zone auto-
matic climate control or 3-zone automatic cli-
mate control.
RYou can switch on climate control by using the
Ãand¿ orà andÁ buttons.
The indicator lamps in the Ãand
¿ buttons or the ÃandÁ buttons
light up.
RVehicles with 3-zone automatic climate
control: in automatic mode, you can also use
the ñ button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The MEDIUM
level is recommended.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
RVehicles with 3-zone automatic climate
control: use the ZONE function to adopt the
temperature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the á button goes out.
RVehicles with 3-zone automatic climate
control: use the "residual heat" function if
you want to heat or ventilate the vehicle inte- rior when the ignition is switched off. The
residual heat function can only be activated or
deactivated with the ignition switched off.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 140).

Problems with the rear window defroster
ProblemPossible causes/consequences andMSolutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated.The battery has not been sufficiently charged.
XSwitch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window defroster
can be activated again.
Switching air-recirculation mode
on/off
General notes
You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle from
outside. The air already inside the vehicle will
then be recirculated.
If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.
Activating/deactivating
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 135).
XTo activate: press thedbutton.
The indicator lamp in the dbutton lights
up.
iIn the event of high pollution levels (3-zone
automatic climate control only) or at high out-
side temperatures, air-recirculation mode is
automatically activated. When air-recircula-
tion mode is activated automatically, the indi-
cator lamp in the dbutton is not lit.
Outside air is added after about 30 minutes.
XTo deactivate: press thedbutton.
The indicator lamp in the dbutton goes
out.
iAir-recirculation mode deactivates auto-
matically:
Rafter approximately five minutes at outside
temperatures below approximately 41 ‡
(5 †)
Rafter approximately five minutes if cooling
with air dehumidification is deactivated
Rafter approximately 30 minutes at outside
temperatures above approximately 41 ‡ (5 †) if the "Cooling with air dehumidifi-
cation" function is activated
Switching the residual heat on or off
General notes
The residual heat function is only available on
vehicles for Canada.
It is possible to make use of the residual heat of
the engine to continue heating the stationary
vehicle for up to 30 minutes after the engine has
been switched off. The heating time depends on
the set interior temperature.
Activating/deactivating
XTo activate: press theÌorÁ button.
The indicator lamp in the ÌorÁ button
lights up.
iThe blower will run at a low speed regardless
of the airflow setting.
iIf you activate the residual heat function at
high temperatures, only the ventilation will be
activated. The blower runs at medium speed.
XTo deactivate: press theÌorÁ but-
ton.
The indicator lamp in the ÌorÁ button

Ionization
Ionization is used to purify the air in the vehicle
interior and attain an improved interior climate.
Operating the climate control systems131
Climate control

The ionization of the interior air is odorless and
cannot be perceived directly in the vehicle inte-
rior.
You can switch ionization on and off via the mul-
timedia system (see the Digital Operator's Man-
ual).
Ionization can only be operated when the auto-
matic climate control is switched on. The side air
vent on the driver's side must be open.
Setting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet grille on the hood and in the
engine compartment on the front-passenger
side free of blockages, such as ice, snow or
leaves.
Rnever cover the air vents or air intake grilles in
the vehicle interior.
iFor virtually draft-free ventilation, adjust the
sliders of the air vents to the center position.
Setting the center air vents
:Center air vent, left
;Center air vent, right
=Center vent thumbwheel, right
?Center vent thumbwheel, left
XTo open or close: turn thumbwheels=
and ?to the left or right.

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehiclehas been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future.
RYou should therefore drive at varying vehicle
and engine speeds for the first 1000 miles
(1500 km).
RAvoid heavy loads, e.g. driving at full throttle,during this period.
RChange gear in good time, before the tach-
ometer needle is Ôof the way to the red area
of the tachometer.
RDo not manually shift to a lower gear to brake
the vehicle.
RTry to avoid depressing the accelerator pedal
beyond the point of resistance (kickdown).
Additional breaking-in notes for Mercedes-AMG
vehicles:
RDo not drive faster than 85 mph (140 km/h)
for the first 1,000 miles (1,500 km).
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
RChange gear in good time.
RIdeally, for the first 1,000 miles (1,500 km),
drive in the Comfortdrive program.
After 1000 miles (1500 km),you can increase
th eengin espeed gradually and accelerate th e
vehicl eto full speed.
You should also observ ethese note son break-
in g in if th eengin eor part sof th edri ve tra
in on
your vehicl ehav ebeen replaced.
Always observ eth emaximum permissibl e
speed.

134Driving
Driving and parking

!Do not warm up the engine while stationary.
Pull away immediately. Avoid high engine
speeds and full throttle until the engine has
reached its operating temperature.
In vehicles with automatic transmission,
engage positions P and R only when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.
Plug-in hybrid: be sure to read the separate
Operator's Manual. Otherwise, you may not rec-
ognize dangers.

As soon as the ignition is switched on, all the
indicator lamps in the instrument cluster light
up. Further information on situations where an
indicator lamp either fails to go out after starting
the engine or lights up while driving
(
Ypage 276).
If the SmartKey is in position uin the ignition
lock for a longer period, it can no longer be
turned in the ignition lock. The steering is then locked. To unlock, remove the SmartKey and
reinsert it into the ignition lock.
The steering is locked when you remove the
SmartKey from the ignition lock.
XRemove the SmartKey when the engine is
switched off.
The starter battery could otherwise be dis-
charged.
If you cannot turn the SmartKey in the ignition
lock, the starter battery may not be charged
sufficiently.
XCheck the starter battery and charge it if nec-
essary (Ypage 342).
or
XJump-start the vehicle (Ypage 342).
iThe SmartKey can be turned in the ignition
lock even if it is not the correct SmartKey for
the vehicle. The ignition is not switched on.
The engine cannot be started.
KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with a
SmartKey featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
Key positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in the
ignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 78).
