356 Customer Information
If the vehicle cannot be scheduled into the
service department immediately, keep
driving it until it can be scheduled for
service, unless, of course, the problem is
safety related. If it is, please call your
dealership, let them know this, and ask for
instructions.
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), Federal Emission,
Extended Powertrain or Electric 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”
produced for
new vehicles 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.

Vehicle Data Recording and
Privacy
The vehicle has a number of computers that
record information about the vehicle’s
performance and how it is driven or used.
For example, the vehicle uses computer
modules to monitor and control engine and
transmission performance, to monitor the
conditions for airbag deployment and
deploy them in a crash, and, if equipped, to
provide antilock braking to help the driver
control the vehicle. These modules may
store data to help the dealer technician
service the vehicle or to help GM improve
safety or features. Some modules may also
store data about how the vehicle is
operated, such as rate of fuel consumption
or average speed. These modules may retain
personal preferences, such as radio presets,
seat positions, and temperature settings.
Cybersecurity
GM collects information about the use of
your vehicle including operational and safety
related information. We collect this
information to provide, evaluate, improve,
and troubleshoot our products and services
and to develop new products and services.
