Vehicle Data Recording And Privacy; Event Data Recorders - Hummer 2008 H2 Owner's Manual

Vehicle Data Recording
and Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the vehicle's
performance and how it is driven. For example, your
vehicle uses computer modules to monitor and control
engine and transmission performance, to monitor the
conditions for airbag deployment and deploy airbags in a
crash and, if so equipped, to provide antilock braking to
help the driver control the vehicle. These modules may
store data to help your dealer/retailer technician service
your vehicle. Some modules may also store data about
how you operate the vehicle, such as rate of fuel
consumption or average speed. These modules may also
retain the owner's personal preferences, such as radio
pre-sets, seat positions, and temperature settings.

Event Data Recorders

This vehicle has 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 airbag deployment
or hitting a road obstacle, data that will assist in
understanding how a vehicle's systems performed.
7-16
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 pressing the
accelerator and/or brake pedal
•
How fast the vehicle was traveling
This data can help provide a better understanding of the
circumstances in which crashes and injuries occur.
Important: 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) is 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, can read the information if they have
access to the vehicle or the EDR.
