Aftermarket Engine Performance
Enhancement Products and
Modifications
Some aftermarket engine performance products
and modifications promise a way to increase
the horsepower and torque levels of your vehicle's
powertrain. You should be aware that these
products may have detrimental effects on the
performance and life of the engine, exhaust
emission system, transmission, and drivetrain. The
®
DURAMAX
Diesel Engine, Allison Automatic
®
Transmission
, and drivetrain have been designed
and built to offer industry leading durability and
performance in the most demanding applications.
Engine power enhancement products may
enable the engine to operate at horsepower and
torque levels that could damage, create failure, or
reduce the life of the engine, engine emission
system, transmission, and drivetrain. Damage,
failure, or reduced life of the engine, transmission,
emission system, drivetrain or other vehicle
components caused by aftermarket engine
performance enhancement products or
modifications may not be covered under your
vehicle warranty.

After-Manufacture "Rustproofing"
Your vehicle was designed and built to resist
corrosion. Application of additional rust-inhibiting
materials is neither necessary nor required
under the Sheet Metal Coverage. GM makes no
recommendations concerning the usefulness
or value of such products.
Application of after-manufacture rustproofing
products may create an environment which
reduces the corrosion resistance built into your
vehicle. Repairs to correct damage caused
by such applications are not covered under your
New Vehicle Limited Warranty.
Paint, Trim, and Appearance Items
Defects in paint, trim, upholstery, or other
appearance items are normally corrected during
new vehicle preparation. If you find any paint
or appearance concerns, advise your dealer as
soon as possible. Your owner manual has
instructions regarding the care of these items.
