Customer Information 343
If your dealer requests you to bring the
vehicle for service, you are urged to do so
as early in the work day as possible to
allow for same-day repair.
Courtesy Transportation Program
To enhance your ownership experience, we
and our participating dealers are proud to
offer Courtesy Transportation, a customer
support program for vehicles with the
Bumper-to-Bumper (Base Warranty Coverage
period in Canada), extended powertrain,
and/or hybrid-specific warranties in both the
U.S. and Canada.
Several Courtesy Transportation options are
available to assist in reducing inconvenience
when warranty repairs are required.
Courtesy Transportation is not a part of the
New Vehicle Limited Warranty. A separate
manual entitled“Limited Warranty and
Owner Assistance Information” furnished
with each new vehicle provides detailed
warranty coverage information.
Transportation Options
Warranty service can generally be
completed while you wait. However, if you
are unable to do so, your dealer may offer
the following transportation options: Shuttle Service
This includes one-way or round-trip shuttle
service within reasonable time and distance
parameters of your dealer's area.
Public Transportation or Fuel Reimbursement
If overnight warranty repairs are needed,
and public transportation is used, the
expense must be supported by original
receipts and within the maximum amount
allowed by GM. If U.S. customers arrange
their own transportation, limited
reimbursement for reasonable fuel expenses
may be available. Claim amounts should
reflect actual costs and be supported by
original receipts. See your dealer for
information.
Courtesy Rental Vehicle
For an overnight warranty repair, the dealer
may provide an available courtesy rental
vehicle or provide for reimbursement of a
rental vehicle. Reimbursement is limited and
must be supported by original receipts as
well as a signed and completed rental
agreement and meet state/provincial, local,
and rental vehicle provider requirements.
Requirements vary and may include
minimum age requirements, insurance
coverage, credit card, etc. Additional fees
such as fuel, rental vehicle insurance, taxes,
levies, usage fees, excessive mileage,
or rental usage beyond the completion of
the repair are also your responsibility.
It may not be possible to provide a like
vehicle as a courtesy rental.
Additional Program Information
All program options, such as shuttle service,
may not be available at every dealer.
Contact your dealer for specific availability.
General Motors reserves the right to
unilaterally modify, change, or discontinue
Courtesy Transportation at any time and to
resolve all questions of claim eligibility
pursuant to the terms and conditions
described herein at its sole discretion.
Collision Damage Repair
If the vehicle is involved in a collision and it
is damaged, have the damage repaired by a
qualified technician using the proper
equipment and quality replacement parts.
Poorly performed collision repairs diminish
the vehicle resale value, and safety
performance can be compromised in
subsequent collisions.

services, system limitations, and OnStar User
Terms, Privacy Statement, and Software
Terms:

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 0346.
Services for People with Disabilities
Advisors provide services to help with
physical disabilities and medical conditions.
Press
Qto help:
.Locate a gas station with an attendant to
pump gas.
.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.
If equipped, TTY mode can be turned on or
off by touching Settings, then Apps, and

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 0256. 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 OnStar privacy statement or
separately disclosed at the time of
installation. These updates or changes may
also cause a system to automatically
communicate with GM servers to collect
information about vehicle system status,
