Vehicle Data
Recording and
Privacy
This GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, the vehicle uses
computer modules to monitor and
control engine and electric drive unit
performance, to monitor the
conditions for airbag deployment
and to deploy airbags in a crash,
and to provide antilock braking to
help the driver control the vehicle.
These modules may store data to
help your dealer technician service
the 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.
