WARNING
In order to avoid distraction which could
lead to an accident, the driver should enter system settings with the vehicle at a stand- still and operate the system only when roadand traffic conditions permit. Always pay
full attention to traffic conditions first
before operating system controls while
driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approx-
imately 14 m) every second. G
WARNING
Always select a volume that allows you to
still hear ambient sound in your immediate vicinity (e.g. horns, emergency rescue
vehicles, police vehicles, etc.). You could
otherwise cause an accident. G
WARNING
If you wish to have an audio system other
than an original smart audio system fitted
in your vehicle, please always have the nec- essary work performed at an authorized
smart center.
This is particularly important if your
vehicle is fitted with a radio preinstalla-
tion. Improper connection can result in the
failure of important vehicle functions,
thereby endangering the operating safety
of your vehicle and thus your own safety and that of other people.
The following pages contain a brief
description of the audio systems available for the coupé and cabriolet.
The devices are described with their full
complement of equipment. The description
for your individual equipment specifica-
tion applies.
Please refer to the separate operating
instructions for detailed functions. Audio system*

Cruise control*
The cruise control maintains the speed you set for your vehicle automatically. On
downhill grades, the cruise control does
not brake the vehicle via the brake system.
The cruise control can only use the braking power of the engine. You must apply the
brakes yourself in order to reduce the
vehicle speed. The cruise control will then
be canceled. G
WARNING
The cruise control is a convenience system designed to assist the driver during vehi-
cle operation. The cruise control cannot
take road, traffic, and weather conditions
into account. The driver is and must always
remain responsible for the vehicle’s speed and for safe brake operation. Do not use the cruise control
R if the road, traffic, and weather condi-
tions do not make it advisable to travel at
a constant speed
R on slippery roads
Rapid changes in tire traction can result
in wheel spin and loss of control.

Notes
G
WARNING
Follow the recommended settings for heat-
ing and cooling given on the following pages. Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
The air conditioning improves the level of
comfort when driving at high outside tem-
peratures by cooling and dehumidifying
the air.
Nearly all dust particles, pollutants, are
filtered out by an integrated particle fil-
ter before outside air enters the passenger compartment through the air distribution
system. It also operates when the air con-
ditioning is switched off and you have
switched on the blower.
The dehumidification of the air by the air
conditioner prevents the windows from
misting up when the outside air humidity
is high.
This effect can also be used to defrost the
windows. For this, make sure, in addition
to the air conditioner, that the heater is on the maximum setting.
The air conditioner only works when:
R the ignition is switched on
R the blower is switched on
R the driver's door is closed
Maximum effectiveness is achieved if you
drive with the windows closed.
If the operating temperature of the
high‑voltage battery is too high, the
high‑voltage battery is cooled by the air
conditioner. When the air conditioner
switches on, the cooling output in the vehi- cle's interior is reduced as a result. The
temperature in the vehicle's interior may
rise briefly.
If the air conditioner is not switched on,
the compressor of the air conditioner and
the vehicle's cooling fan are switched on
automatically. This cools the high‑voltage
battery but not the vehicle's interior. When
the high‑voltage battery reaches the nom-
inal temperature again, the air condi-
tioner switches off automatically. Air conditioning with climate control

G
WARNING
When operating the heating or air condi-
tioning with climate control, the air that
enters the passenger compartment through
the air vents can be very hot or very cold
(depending on the set temperature). This
may cause burns or frostbite on unprotected skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribu-
tion control to direct the air to air vents in the vehicle interior that are not in the
immediate area of unprotected skin.
To make sure the heating or air condition-
ing with climate control works properly,
please observe the following:

WARNING
Never drive with iced up or fogged win-
dows. Visibility will be significantly
impaired. Impaired visibility could
endanger yourself and others. This may
prevent you from observing the traffic con- ditions, thereby causing an accident.
The best defrosting of windows is achieved
if the ice is completely removed from the
windows manually with an ice scraper
before driving off.
Also use the "Air conditioning before
start" function (Y page 90).

The rear window defroster serves to de-ice
the rear window quickly and clear the view if the rear window is fogged.
The rear window defroster uses a large
amount of power. To keep battery drain to a
minimum, switch off the rear window
defroster as soon as the rear window is
clear. The rear window defroster is auto-
matically deactivated after approximately 10 minutes of operation. X

Switch to air recirculation mode to prevent unpleasant odors from entering the vehicle
from the outside (e.g. before driving
through a tunnel). This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment. G
WARNING
When the air recirculation mode is
switched on, windows can fog on the inside immediately. Fogged windows impair vis-
ibility, endangering you and others. If the
windows begin to fog on the inside, switch- ing off the air recirculation mode imme-
diately should clear interior window fog-
ging. If interior window fogging persists,
make sure the air conditioning is switched on, turn air distribution control Bto
