OnStar or connected 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 or
connected services. Service
involving location information
about the vehicle cannot work
unless GPS signals are
available, unobstructed, and
compatible with the OnStar hardware. OnStar or
connected 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 or
connected 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 0446.

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
Q
or 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. Press
Q
and 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 an extended
period of time without an
ignition cycle. To find out the
duration of time that applies
for the vehicle, contact an
OnStar Advisor by pressing
Q
or calling 1-888-4ONSTAR.
If the vehicle has not been
started for an extended period
of time, 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 callOnStar. 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.
