Fuel GMC YUKON 2008 Repair Manual

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.
Event Data Recorders
This vehicle has an Event Data Recorder (EDR).
The main purpose of an EDR is to record, in certain
crash or near crash-like situations, such as an airbag
deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems
performed. The EDR is designed to record data related
to vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The EDR in
this vehicle is designed to record such data as:
How various systems in your vehicle were operating
Whether or not the driver and passenger safety
belts were buckled/fastened
How far, if at all, the driver was pressing the
accelerator and/or brake pedal
How fast the vehicle was traveling
This data can help provide a better understanding of the
circumstances in which crashes and injuries occur.
Important:EDR data is recorded by your vehicle only
if a non-trivial crash situation occurs; no data is
recorded by the EDR under normal driving conditions
and no personal data (e.g., name, gender, age,
and crash location) is recorded. However, other parties,
such as law enforcement, could combine the EDR
data with the type of personally identifying data routinely
acquired during a crash investigation.
