2008 CHEVROLET SILVERADO Fuel

Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait, GM helps to
minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Shuttle service is the preferred means of offering
Courtesy Transportation. Dealers may provide you with
shuttle service to get you to your destination with minimal
interruption of your daily schedule. This includes one-way
or round trip shuttle service within reasonable time and
distance parameters of the dealer’s area.
Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight warranty repairs, and
public transportation is used instead of the dealer’s
shuttle service, the expense must be supported by
original receipts and can only be up to the maximum
amount allowed by GM for shuttle service. In addition, for
U.S. customers, should you arrange transportation
through a friend or relative, limited reimbursement for
reasonable fuel expenses may be available. Claim
amounts should reect actual costs and be supported by
original receipts. See your dealer for information
regarding the allowance amounts for reimbursement of
fuel or other transportation costs.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle
that you obtain if your vehicle is kept for an overnight
warranty repair. Rental reimbursement will be limited
and must be supported by original receipts. This
requires that you sign and complete a 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. You are responsible for fuel usage
charges and may also be responsible for taxes, levies,
usage fees, excessive mileage, or rental usage
beyond the completion of the repair.
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. Please contact your dealer
for specic information about availability. All Courtesy
Transportation arrangements will be administered
by appropriate dealer personnel.
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
Your GM vehicle has a number of sophisticated
computers that record information about the vehicle’s
performance and how it is driven. For example,
your vehicle uses computer modules to monitor and
control engine and transmission performance, to monitor
the conditions for airbag deployment and deploy
airbags in a crash and, if so equipped, to provide
antilock braking to help the driver control the vehicle.
These modules may store data to help your
dealer/retailer technician service your vehicle. Some
modules may also store data about how you operate the
vehicle, such as rate of fuel consumption or average
speed. These modules may also retain the owner’s
personal preferences, such as radio pre-sets, seat
positions, and temperature settings.
