2014 MERCEDES-BENZ C-Class change time

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.

harmful interference, and 2) These devices

expressly approved by the party responsible

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

switching off Audio 20, switch the mobile
phone to "Private mode" (see the mobile
phone operating instructions). "911" emergency call

Using it without due cause is a criminal
offense.
The following requirements must be fulfilled
for a 911emergency call:
R the mobile phone must be switched on.
R a network must be available.
R a valid and operational SIM card must be
inserted in the mobile phone.
R the mobile phone must be connected to
Audio 20 via Bluetooth ®
.

®
inter-
face Prerequisites
To use Bluetooth ®
interface telephony in con-
junction with Audio 20, you need a Blue-
tooth ®
-capable mobile phone.
On Audio 20
X Activate the Bluetooth ®
function on
Audio 20 (Y page 33).
On the mobile phone
X Switch on the mobile phone and enter the
PIN when prompted to do so (see the
mobile phone operating instructions).
X Activate Bluetooth ®
functions and, where
necessary, Bluetooth ®
visibility on the
mobile phone (see the mobile phone oper-
ating instructions).
The battery of the mobile phone should
always be kept sufficiently charged in order
to prevent malfunctions.
In preparation for telephoning via the Blue-
tooth ®
interface, you should check the fol-
lowing items on your mobile phone (see the
mobile phone operating instructions):
R Hands-Free Profile
The mobile phone must support Hands-
Free Profile 1.0 or above.
R Bluetooth ®
visibility
On some mobile phones, it is not enough to
activate only the Bluetooth ®
function. Your
device must also be made "visible" to other
devices (see the mobile phone operating
instructions).
This visibility is for restricted periods of
time on some mobile phones.
R Bluetooth ®
device name
Every Bluetooth ®
device has its own Blue-
tooth ®
device name. This device name is
freely definable, but can be identical for all
devices from the same manufacturer. It is
therefore recommended that you change
this name so that you can easily recognize Telephony via the Bluetooth
