Accessories and
Modifications
Adding non‐dealer accessories
to the vehicle can affect vehicle
performance and safety, including
such things as airbags, braking,
stability, ride and handling,
emissions systems, aerodynamics,
durability, and electronic systems
like antilock brakes, traction control,
and stability control. Some of these
accessories could even cause
malfunction or damage not covered
by the vehicle warranty.
Damage to vehicle components
resulting from the installation or use
of non‐GM certified parts, including
control module modifications, is not
covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.
GM Accessories are designed to
complement and function with other
systems on the vehicle. Your GM
dealer can accessorize the vehicle
using genuine GM Accessories.
When you go to your GM dealer
and ask for GM Accessories, you
will know that GM-trained and
supported service technicians will
perform the work using genuine GM
Accessories.

Airbag-Equipped Vehicle on
