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.
