Event data recorders
USA only:
This vehicleisequippedwith an event data
recorder (EDR). This vehicleisequippedwith
an event data recorder (EDR). The main pur-
pose of an EDR is to record, in certain crash or
near crash-like situations, such as an air bag
deployment or hitting aroad obstacle, data
that willassist in understanding how avehi-
cle's systems performed.The EDR is designed
to record data related to vehicledynamics and
safety systems for ashort periodoftime, typi-
cally30seconds or less.
The EDR in this vehicleisdesigned to record
such data as:
R
How various systems in yourvehiclewere
operating
R
Whether or not the driver and passenger
safety belts were buckled/fastened
R
How far (if at all)the driver was depressing
the accelerator and/or brake pedal; and,
R
How fast the vehiclewas traveling
These data can help provideabetter under-
standing of the circumstances in which
crashes and injuriesoccur. NOTE: EDR data
are recorded by yourvehicleonly if anon-triv-
ial crash situation occurs; no data are recor-
ded by the EDR under normal driving condi-
tions and no personaldata (e.g. name, gender,
age and crash location) are recorded.How-
ever, other parties, such as law enforcement
could combine the EDR data with the type of
personally identifying data routinelyacquired
during acrash investigation.
Access to the vehicleand/or the EDR is nee-
ded to read data that is recorded by an EDR,
and specialequipment is required. In addition
