Warning!
Please devote your attention first and
foremost to the traffic situation you are in.
Before your journey, please familiarize
yourself with the radio functions.
Only use the audio system when road and
traffic conditions permit you to do so.
Otherwise you could be involved in an
accident in which you or others could be
injured.
! Do not attach metallic window tinting film
to the inside or outside of windows which
are fitted with an aerial. Obstructing the
metallic aerial structure on the window will
interfere with radio reception. Cutting the
film on the window can permanently
damage the aerial wires.

i The “911” emergency call system is a
public service. Using it without due cause
is a criminal offense.
i This function places a call to the local
“911” provider. It does not initiate a Tele
Aid call.
The following describes how to dial a “911”
emergency call using the audio system head
unit when a Mercedes-Benz specified mobile
phone is connected via the Bluetooth ®
interface to the audio system. Unless
otherwise

specified, the descriptions refer to
the audio system head unit.
Consult the separate mobile phone operating
instructions that came with your mobile
phone for information on how to place a
“911” emergency call on the mobile phone.
The following conditions must be met for a
“911” emergency call via the audio system:
R Mobile phone must be switched on.
R The corresponding mobile
communications network must be
available.
i Emergency calls may not be possible with
all telephone networks or if certain network
services and/or telephone functions are
active. Check with your local service
providers and mobile phone instructions.
If you cannot make an emergency call, you
will have to initiate rescue measures yourself.

Notes on climate control system
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic 9
or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the retractable
hardtop closed.
Nearly

all dust particles, pollutants and odors
are filtered out before outside air enters the passenger compartment through the air
distribution system. G
Warning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its

scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.

The air conditioning is operational while the
engine

is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging. G
Warning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions

are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
Deactivating It is possible to deactivate the air
conditioning. The interior air will then no
longer be cooled or dehumidified.

G
Warning!
When operating the 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 to 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 distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
X Keep the air intake grille in front of the
windshield

free of snow, leaves, sticks, and
any other debris.
X Always keep all air vents and grilles in the
passenger compartment free from
obstruction.

This provides the fastest possible cooling of
the

vehicle interior (when retractable hardtop
is closed). Air recirculation mode
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!

With the engine turned off, it is possible to
continue to heat or ventilate the interior for
up to 30 minutes. This feature makes use of
the residual heat produced by the engine.
i If

you switch on the residual heat function
when outside temperatures are high, only
