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.
Collision Parts
Genuine GM Collision parts are new
parts made with the same materials
and construction methods as the
parts with which the vehicle was
originally built. Genuine GM
Collision parts are the best choice to
ensure that the vehicle's designed
appearance, durability, and safety
are preserved. The use of Genuine
GM parts can help maintain the GM
New Vehicle Limited Warranty.
Recycled original equipment parts
may also be used for repair. These
parts are typically removed from
vehicles that were total losses in
prior crashes. In most cases, the
parts being recycled are from
undamaged sections of the vehicle.
A recycled original equipment GM
part may be an acceptable choice to
maintain the vehicle's originally
designed appearance and safety
performance; however, the history of
these parts is not known. Such parts
are not covered by the GM New
Vehicle Limited Warranty, and any
related failures are not covered by
that warranty.

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. 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.
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.
