electronic access, detecting
possible malicious activity in
related networks, and
responding to suspected
cybersecurity incidents in a
timely, coordinated and
effective manner. Security
incidents could impact your
safety or compromise your
private data. To minimize
security risks, please do not
connect your vehicle
electronic systems to
unauthorized devices or
connect your vehicle to any
unknown or untrusted
networks (such as Bluetooth,
WIFI or similar technology). In
the event you suspect any
security incident impacting
your data or the safe
operation of your vehicle,
please stop operating your
vehicle and contact your
dealer.Event Data Recorders
This vehicle is equipped with
an Event Data Recorder (EDR).
The main purpose of an EDR is
to record, in certain crash or
near crash-like situations, such
as an air bag deployment or
hitting a road obstacle, data
that will assist in
understanding how a vehicle’s
systems performed. 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:
.How various systems in your
vehicle were operating;
.Whether or not the driver
and passenger safety belts
were buckled/fastened;
.How far (if at all) the driver
was depressing the
accelerator and/or brake
pedal; and,
.How fast the vehicle was
traveling.These data can help provide a
better understanding of the
circumstances in which
crashes and injuries occur.
Note
EDR data are recorded by
your vehicle only if a non-trivial
crash situation occurs; no data
are recorded by the EDR
under normal driving
conditions and no personal
data (e.g., name, gender, age,
and crash location) are
recorded. However, other
parties, such as law
enforcement, could combine
the EDR data with the type of
personally identifying data
routinely acquired during a
crash investigation.
To read data recorded by an
EDR, special equipment is
required, and access to the
vehicle or the EDR is needed.
In addition to the vehicle
manufacturer, other parties,
such as law enforcement, that
have the special equipment,
