2012 MERCEDES-BENZ SL ROADSTER technical data

Media Interface mode
Connection options Overview
You will find the connection sockets in the
centre console stowage compartment.
Device-specific adapter cables are required
to connect external devices to the Media
Interface. These are supplied in country-spe-
cific versions with the Media Interface
(Y
page 494).
You can connect the following data carriers to
COMAND Online via the Media Interface:
R iPod ®
R iPhone ®
R certain MP3 players
i Store individual parts in a safe place.
Only use genuine Mercedes-Benz connec-
tion cables.
i iPod ®
and iPhone ®
are registered trade-
marks of Apple Inc., Cupertino, California,
USA.
i MP3 players that support MTP (
Media
Transfer Protocol) can be used.
This allows the MP3 player to be easily con- nected to the Media Interface and removed
after use. Audio data is played without
problems.
On some MP3 players, you have to activate
the relevant function; see the MP3 player
operating instructions.
Supported devices

devices, contact a Mercedes-Benz Service
Centre or visit the website at http://

"Media Interface" section. Connecting an external device Do not leave external devices in the vehicle.
At extreme temperatures, they cannot be
guaranteed to function correctly (see the
operating instructions of the device in ques-
tion). Examples of extreme temperatures are direct sunlight or very low outside tempera-
tures. Mercedes-Benz accepts no liability for
damage to external devices.
i Never connect more than one device at a
time. You will otherwise not be able to play
back from the external device.
USB hubs (devices with several USB con-
nections) are not supported. :

not be simultaneously operated via the
Media Interface and the remote control

Emergency spare wheel
Important safety notes
G
WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
To prevent hazardous situations:
R Adapt your driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimensions are different to those of the wheel being replaced.
R Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
You should regularly check the pressure of all your tyres, including the emergency spare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 600).
The applicable value is found on the wheel or
under "Technical data" (Y page 617).
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the time restriction on use as well as the speed
limitation specified on the emergency spare
wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i If you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Do not restart the tyre pressure loss warn-
ing system/tyre pressure monitor until the
defective wheel has been replaced with a
new wheel.
Vehicles with a tyre pressure monitor:
for a few minutes after an emergency spare wheel is fitted, the system may still display
the tyre pressure of the removed wheel.
The value displayed for the mounted emer-
gency spare wheel is not the same as the
current tyre pressure of the emergency
spare wheel.
4 Observe notes on "Large wheels" in the "Wheel/tyre combinations" section. 614

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 34). Information on technical data
General notes
You can find current technical data on the
Internet on our Mercedes‑ Benz homepage.
i The technical data was determined in
accordance with EU Directives. All data
applies to the vehicle's standard equip-
ment. The data may therefore differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre. Vehicle electronics
Tampering with the engine electron-
ics
! Only have work carried out on the engine
electronics and its associated parts, such
as control units, sensors and connector
leads, at a qualified specialist workshop.
Vehicle components may otherwise wear
more quickly and the vehicle's operating
permit may be invalidated. Retrofitting two-way radios and
mobile phones (RF transmitters)
G
WARNING
If RF transmitters are tampered with or not
properly retrofitted, the electromagnetic radi- ation they emit can interfere with the vehicle
electronics. This may jeopardise the opera-
tional safety of the vehicle. There is a risk of an
accident.
You should have all work on electrical and
electronic components carried out at a quali-
fied specialist workshop. G
WARNING
If you use the RF transmitter in the vehicle in
an improper way, its electromagnetic radia-
tion can disrupt vehicle electronics, e.g. if:
R the RF transmitter is not connected to an
exterior aerial
R the exterior aerial is fitted incorrectly or is
not a low-reflection aerial
This can jeopardise the operating safety of the vehicle. There is a risk of an accident.
Have the low-reflection exterior aerial fitted at
a qualified specialist workshop. When oper-
ating in the vehicle, always connect the RF
transmitter to the low-reflection exterior aer-
ial.
! The operating permit may be invalidated if
the instructions for installation and use of
RF transmitters are not observed.
In particular, the following conditions must be complied with:
R only approved wavebands may be used.
R observe the maximum permissible out-
put in these wavebands.
R only approved aerial positions may be
used.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus- 620
Vehicle electronicsTechnical data

sion surrounding the possible health risk
posed by electromagnetic fields.
Observe the notes on operating mobile
phones (Y page 551).
The following aerial positions may be used for the correct installation of RF transmitters: Approved aerial positions
:
Rear wing
i On the rear wing, it is recommended that
you position the aerial on the side of the
vehicle closest to the centre of the road.
Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for fitting
aftermarket radio frequency transmitting
equipment") when retrofitting RF (radio fre-
quency) transmitters. Comply with the legal
requirements for add-on parts.
If your vehicle has fittings for two-way radio
equipment, use the power supply or aerial
connections intended for use with the basic
wiring. Be sure to observe the manufacturer's additional instructions when installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or aerial positions must be approved by Mercedes-Benz. The maximum transmission output (PEAK) at
the base of the aerial must not exceed the
following values: Waveband Maximum
transmission output Short wave
3 - 54 MHz 30 W
4 m waveband
74 - 78 MHz 15 W
2 m waveband
144 - 174 MHz 25 W
Trunked radio/Tetra
380 - 460 MHz 10 W
70 cm waveband
400 - 460 MHz 15 W
GSM/DCS/PCS
850/900/1800/1900 10 W
UMTS/LTE 10 W
The following can be used in the vehicle with-
out restrictions:
R RF transmitters with a maximum transmis-
sion output of up to 100 mW
R Mobile phones (GSM/DCS/PCS/UMTS/
LTE)
There are no restrictions when positioning the aerial on the outside of the vehicle for the fol-
lowing wavebands:
R Trunked radio/Tetra
R 70 cm waveband
R GSM/DCS/PCS
R UMTS/LTE Vehicle electronics
