Customer Information 397
Vehicle Data
Recording and
Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven or used. For
example, the vehicle uses computer
modules to monitor and control
engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy them in a crash, and,
if equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help the dealer technician
service the vehicle or to help GM
improve safety or features. Some
modules may also store data about
how the vehicle is operated, such as
rate of fuel consumption or average
speed. These modules may retain
personal preferences, such as radio
presets, seat positions, and
temperature settings.
Cybersecurity
GM collects information about the
use of your vehicle including
operational and safety related
information. We collect this
information to provide, evaluate,
improve, and troubleshoot our
products and services and to
develop new products and services.
The protection of vehicle electronics
systems and customer data from
unauthorized outside electronic
access or control is important to
GM. GM maintains appropriate
security standards, practices,
guidelines and controls aimed at
defending the vehicle and the
vehicle service ecosystem against
unauthorized electronic access,
detecting possible malicious activity
in related networks, and responding
to suspected cybersecurity incidents
in a timely, coordinated and effective
manner. Security incidents could
impact your safety or compromise
your private data. To minimize
security risks, please do not connect
your vehicle electronic systems to
unauthorized devices or connectyour vehicle to any unknown or
untrusted networks (such as
Bluetooth, WIFI or similar
technology). In the event you
suspect any security incident
impacting your data or the safe
operation of your vehicle, please
stop operating your vehicle and
contact your dealer.
Event Data Recorders
This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an air
bag deployment or hitting a road
obstacle, data that will assist in
understanding how a vehicle’s
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:

OnStar 403
Languages
The vehicle can be programmed to
respond in multiple languages.
Press
Qand ask for an Advisor.
Advisors are available in English,
Spanish, and French. Available
languages may vary by country.
Potential Issues
OnStar cannot perform Remote
Door Unlock or Stolen Vehicle
Assistance after the vehicle has
been off continuously for 10 days
without an ignition cycle. If the
vehicle has not been started for
10 days, OnStar can contact
Roadside Assistance or a locksmith
to help gain access to the vehicle.
Global Positioning
System (GPS)
. Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels and
underpasses; or in an area with
very dense trees. If GPS signals
are not available, the OnStar
system should still operate to call OnStar. However, OnStar
could have difficulty identifying
the exact location.
. In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.
A temporary loss of GPS can cause
loss of the ability to send a
Turn-by-Turn Navigation route. The
Advisor may give a verbal route or
may ask for a call back after the
vehicle is driven into an open area.
Cellular and GPS Antennas
Cellular reception is required for
OnStar to send remote signals to
the vehicle. Do not place items over
or near the antenna to prevent
blocking cellular and GPS signal
reception.
Unable to Connect to OnStar
Message
If there is limited cellular coverage
or the cellular network has reached
maximum capacity, this message may come on. Press
Qto try the
call again or try again after driving a
few miles into another cellular area.
Vehicle and Power Issues
OnStar services require a vehicle
electrical system, wireless service,
and GPS satellite technologies to be
available and operating for features
to function properly. These systems
may not operate if the battery is
discharged or disconnected.
Add-on Electrical Equipment
The OnStar system is integrated
into the electrical architecture of the
vehicle. Do not add any electrical
equipment. See Add-On Electrical
Equipment 0271. Added electrical
equipment may interfere with the
operation of the OnStar system and
cause it to not operate.
Vehicle Software Updates
OnStar or GM may remotely deliver
software updates or changes to the
vehicle without further notice or
consent. These updates or changes
may enhance or maintain safety,
