Welcome to the world of Mercedes-Benz.
First of all, familiarize yourself with your audio
equipment and read the operating instruc-
tions, especially the safety and warning
notes, before operating the audio equipment.
This will help you to obtain the maximum use
from the system and avoid endangering your-
self and others.
Depending on the model and equipment level,
the functions of your audio equipment may
deviate from certain descriptions and illus-
trations.
Mercedes-Benz is constantly updating its
audio equipment to the state of the art and
therefore reserves the right to introduce
changes in design, equipment and technical
features at any time.
You cannot, therefore, base any claims on the
data, illustrations or descriptions in this man-
ual.
Please consult an authorized Mercedes-Benz
Center should you have any questions.
This manual is an integral part of the vehicle.
You should always keep it in the vehicle and
pass it on to the new owner if you sell the
vehicle.
The technical documentation team at
Daimler AG wishes you safe and pleasant
motoring.

ation is subject to the two following two con-
ditions: 1) These devices may not cause
harmful interference, and 2) These devices
must accept any interference received,
including interference that may cause unde-
sired operation. Changes or modifications not
expressly approved by the party responsible
for compliance could void the user’s authority
to operate the equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference, includ-
ing interference that may cause undesired
operation of the device." Audio system features
These Operating Instructions describe all
standard and optional equipment available
for your audio device at the time of going to
print. Country-specific differences are possi-
ble. Please note that your audio equipment
may not offer all the features described. This
also applies to safety-relevant systems and
functions. The equipment in your vehicle may
therefore differ from that shown in the
descriptions and illustrations.
The original purchase agreement lists all sys-
tems installed in your vehicle. Contact an
authorized Mercedes-Benz Center if you have
any questions about equipment or operation. Function restrictions
For safety reasons, some functions are
restricted or unavailable while the vehicle is
in motion. You will notice this, for example,
because you will not be able to select certain
menu items. Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R The vehicle's operating state
R Incidents
R Malfunctions
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. air bag
deployment, intervention of stability
control systems
R ambient conditions, e.g. outside tempera-
ture
This data is of an exclusively technical nature
and can be used to:
R assist in recognizing and rectifying mal-
functions and defects
R analyze vehicle functions, e.g. after an acci-
dent
R optimize vehicle function
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem-
ory and malfunction data memory.
Services include, for example:
R repair services
R service processes Introduction

R
warranties
R quality assurance
It is read by employees of the service network
(including manufacturers) using special diag-
nostic devices. More detailed information is
obtained from it, if required.
After a malfunction has been rectified, the
information is deleted from the malfunction
memory or is continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if neces-
sary, under consultation with an authorized
expert), could be traced to a person.
Examples include:
R accident reports
R damages to the vehicle
R witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case
of an emergency. 10
