WARNING
In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a
standstill and operate the system only when
road and 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
(approximately 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
necessary work performed at an authorized
smart center.
This is particularly important if your
vehicle is fitted with a radio
preinstallation. 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

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
vehicle 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
conditions 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.
R when driving in fog
The use of the cruise control is
recommended for driving at a constant
speed for extended periods of time.

WARNING
Follow the recommended settings for
heating
and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
Air conditioning with climate control* The air conditioning improves the level of
comfort when driving at high outside
temperatures by cooling and
dehumidifying the air.
Nearly all dust particles, pollutants, are
filtered out by an integrated particle
filter before outside air enters the
passenger compartment through the air
distribution
system. It also operates when
the air conditioning is switched off and
you have switched on the blower.
The air conditioning only works when the
engine is running and the blower is
switched on. Maximum effectiveness is
achieved if you drive with the windows
closed.
i In warmer weather, ventilate the
passenger compartment for a short
period of time before utilizing the air
conditioning. 102
