ditions: 1) These devices may not cause
harmful interference, and 2) These devices

expressly approved by the party responsible

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-

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
