h
e 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
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 Q
to 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
ma
y 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 3221. 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 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 Connected
Services Privacy Statement or separately
disclosed at the time of installation. These
