Roadside Assistance, Turn-by-Turn
Navigation, and Hands-Free Calling
are available on most vehicles. Not
all OnStar services are available

limitations, and OnStar terms and
conditions, see www.onstar.com
(U.S.) or www.onstar.ca (Canada);

satellite technologies to be available
and operating for features to
function properly. These systems
may not operate if the battery is
discharged or disconnected.

14-6 OnStar
OnStar service cannot work unless
your vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area, and the wireless
service provider has coverage,
network capacity, reception, and
technology compatible with OnStar’s
service. Service involving location
information about the vehicle cannot
work unless GPS signals are
available, unobstructed, and
compatible with the OnStar
hardware. OnStar service 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 service may not
work. Other problems beyond
OnStar ’s control may prevent
service 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. See
Radio Frequency Statement on
page 13‑20 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.

OnStar 14-7
Warranty
OnStar equipment may be
warranted as part of the new-vehicle
limited warranty. The manufacturer
of the vehicle furnishes detailed
warranty information.
Languages
The vehicle can be programmed
to respond in French or Spanish.

Potential Issues
Some OnStar services are disabled
after five days. OnStar cannot
perform Remote Door Unlock or
Stolen Vehicle Assistance after the
vehicle has been off continuously
for five days. After five days, OnStar
can contact Roadside Assistance
and 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,
underpasses, or parking
garages; 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
Avoid placing items over or near the
antenna to prevent blocking cellular
and GPS signal reception. Cellular
reception is required for OnStar to
send remote signals to the vehicle.
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. Push
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.
