\1\ Pre-crash data and crash data are asynchronous The sample time accuracy requirement for pre-crash time is -
  0.1 to 1.0 sec (e.g., T = -1 would need to occur between -1.1 and 0 seconds)
\2\ ``If recorded'' means if the data is recorded in non-volatile memory for the purpose of subsequent
  downloading
\3\ ``Vehicle roll angle'' may be recorded in any time duration -1.0 to 5.0 seconds is suggested
\4\ List this element n--1 times, once for each stage of a multi-stage air bag system
