Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition to LOCK/OFF in each shift lever position.
For automatic transmission vehicles, the ignition
should turn to LOCK/OFF only when the shift
lever is in P (Park).
With the key access ignition system, the ignition
key should come out only in LOCK/OFF. See
Ignition Positions (Key Access) on page 2-31or
Ignition Positions (Keyless Access) on page 2-32.
Contact your dealer/retailer if service is required.

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.
