The following contains notes and recommenda-
tions on optimum use of dual-zone automatic
climate control.
XActivate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
XSet the temperature to 72 ‡ (22 †).
iOnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear again.
iOnly 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.
DYNAMIC SELECT switch (except
Mercedes-AMG C 63 /C63S)
You can choose between various drive programs
with the DYNAMIC SELECT switch
(
Ypage 130).
If you have selected drive program E:
Rwhen heating, the electrical heater booster is
deactivated and heat output is reduced as a
result
Rthe rear window defroster running time is
reduced If you have selected drive program
C,Sor S+,
the current climate settings are maintained.
ECO start/stop function
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 (

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 77)
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of the Smart-
Key.
If you lock the vehicle with the SmartKey remote control or with KEYLESS-GO, after a short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will no longer be able to start the engine

Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.

The catalytic converter is preheated for up to
30 seconds after a cold start. The sound of the
engine may change during this time.
