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.
