and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.

Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,

including calipers, parking brake, etc. You may need to
have your brakes inspected more often if your driving
habits or conditions result in frequent braking.

minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealers can provide you with shuttle
service to get to your destination with minimal
interruption of your daily schedule. This includes a one
way or round trip shuttle ride to a destination up to
10 miles from the dealership.
Public Transportation or Fuel

If your vehicle requires overnight warranty repairs,
reimbursement (ve days maximum) may be available
for the use of public transportation such a s taxi or
bus. In addition, should you arrange transportation
through a friend or relative, reimbursement for
reasonable fuel expenses (ve day maximum) may be
available. Claim amounts should reect actual costs and
be supported by original receipts.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle
you obtained if your vehicle is kept for a warranty repair.
Reimbursement will be limited to a maximum of $30 a
day and must be supported by receipts. This requires
that you sign and complete a rental agreement and meet
state, local and rental vehicle provider requirements.
Requirements vary and may include minimum age
requirements, insurance coverage, credit card, etc. You
are responsible for taxes, levies, usage fees, excessive
mileage or rental usage beyond the completion of

Vehicle Data Collection and Event
Data Records
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash or near crash
event by computer systems commonly called event data
recorders (EDR).
In a crash or near crash event, computer systems, such
as the Airbag Sensing and Diagnostic Module (SDM) in
your vehicle may record information about the condition
of the vehicle and how it was operated, such as engine
speed, brake applications, throttle position, vehicle
speed, seat belt usage, airbag readiness, airbag
performance data, and the severity of a collision. This
information has been used to improve vehicle crash
performance and may be used to improve crash
performance of future vehicles and driving safety. Unlike
the data recorders on many airplanes, these on-board
systems do not record sounds, such as conversation of
vehicle occupants.
