Information about electronic data
acquisition in the vehicle
(Including notice pursuant to California Code
§ 9951)
Please note that your vehicle is equipped with
devices that can record vehicle systems data.
If your vehicle is equipped with mbrace
(Canada :TELE AID) ,data is transmitted in the
event of an accident. This informatio
nhelps, for example, to test
vehicle systems after an accident and to
continually improve vehicle safety.
Daimler AG can access these data and submit
them:
R for safety research or vehicle diagnosis
purposes
R with the consent of the vehicle owner
R on the instruction of prosecuting
authorities
R for use in arbitration of disputes that
involve Daimler AG, its subsidiaries or its
sales and service organizations
R as otherwise required or permitted by law
Please chec kyour mbrace (Canada: TELE
AID) purchase agreement to find out more
about data that can be recorded and
transmitted by this system.
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record data that will assist in
understanding how a vehicle’s systems
performed in certain crash or near crash-like
situations, such as during air bag deployment
or when hitting a road obstacle. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
R how various systems in your vehicle are
operating
R whether or not the driver and passenger
seat belts are fastened
R how far (if at all) the driver is depressing the
accelerator and/or brake pedal and
R how fast the vehicle is traveling
This data can help provide abetter
understanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data
is recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by
the EDR under normal driving conditions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However, Introduction
