.PressQto speak with an
Advisor.
OnStar services cannot work unless
the vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area. The wireless service
provider must also have coverage,
network capacity, reception, and
technology compatible with OnStar
services. Service involving location
information about the vehicle cannot
work unless GPS signals are
available, unobstructed, and
compatible with the OnStar
hardware. OnStar services may not
work if the OnStar equipment is not
properly installed or it has not been
properly maintained. If equipment or
software is added, connected,
or modified, OnStar services may
not work. Other problems beyond
the control of OnStar —such as
hills, tall buildings, tunnels, weather,
electrical system design and
architecture of the vehicle, damage
to the vehicle in a crash, or wireless
phone network congestion or
jamming —may prevent service. See
Radio Frequency Statement
0 341.
Services for People with
Disabilities
Advisors provide services to help
Subscribers with physical disabilities
and medical conditions.
Press
Qto help:
. Locate a gas station with an

. Find a hotel, restaurant, etc.,
that meets accessibility needs.
. Provide directions to the closest
hospital or pharmacy in urgent
situations.
TTY Users
OnStar has the ability to
communicate to deaf,
hard-of-hearing, or speech-impaired
customers while in the vehicle. The
available dealer-installed TTY
system can provide in-vehicle
access to all OnStar services,
except Virtual Advisor and OnStar
Turn-by-Turn Navigation.
OnStar Personal Identification
Number (PIN)
A PIN is needed to access some
OnStar services. The PIN will need
to be changed the first time when
speaking with an Advisor. To
change the OnStar PIN, contact an
OnStar Advisor by pressing
Qor
calling 1-888-4ONSTAR.
Warranty
OnStar equipment may be
warranted as part of the vehicle
warranty.
Languages
The vehicle can be programmed to
respond in multiple languages.

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 five days
without an ignition cycle. If the

9159388) - 2016 - crc - 5/20/15
OnStar 351
vehicle has not been started for
five 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 0224. 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,
security, or the operation of the
vehicle or the vehicle systems.
Software updates or changes may
affect or erase data or settings that
are stored in the vehicle, such as
OnStar Hands-Free Calling name
tags, saved navigation destinations,
or pre-set radio stations. Neither
OnStar nor GM is responsible for
any affected or erased data or
settings. These updates or changes
may also collect personal
information. Such collection is
described in the OnStar privacy
