10 Things to Know About the New Vehicle Limited Warranty
Warranty Repairs–
Component Exchanges
In the interest of customer
satisfaction, Chevrolet may offer
exchange service on some vehicle
components. This service is
intended to reduce the amount of
time your vehicle is not available for
use due to repairs. Components
used in exchange are service
replacement parts that may be new,
remanufactured, or refurbished.
Remanufactured parts meet
Chevrolet approved service part
requirements and are made from
previously used components in a
process that involves disassembly,
inspection, cleaning, update of
software and replacement of parts
as appropriate, testing and
reassembly.
Refurbished parts meet Chevrolet
approved service part requirements
and are previously used parts that
are inspected, cleaned, tested, and
repackaged. All exchange components used
meet Chevrolet standards and are
warranted the same as new
components. Examples of the types
of components that might be
serviced in this fashion include:
engine and transmission
assemblies, instrument cluster
assemblies, radios, compact disc
players, batteries, and powertrain
control modules.
Warranty Repairs
–Recycled
Materials
Environmental Protection Agency
(EPA) guidelines and Chevrolet
support the capture, purification,
and reuse of automotive air
conditioning refrigerant gases and
engine coolant. As a result, any
repairs Chevrolet may make to your
vehicle may involve the installation
of purified reclaimed refrigerant and
coolant.
Tire Service
Any authorized Chevrolet Low Cab
Forward Truck or tire dealer for your
brand of tires can assist you with
tire service. If, after contacting one of these dealers, you need further
assistance or you have questions,
contact the Chevrolet Customer
Assistance Center. The toll-free
telephone numbers are listed under
Customer Assistance Offices
029.
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 Powertrain has 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,

Chevrolet Low Cab Forward Limited Warranty and Owner Assistance
Information (GMNA-Localizing-U.S-13336102) - 2020 - crc - 12/7/18
Things to Know About the New Vehicle Limited Warranty 11
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 new vehicle
limited warranty.
After-Manufacture
“Rustproofing”
Your Low Cab Forward Truck was
designed and built to resist
corrosion. Application of additional
rust-inhibiting materials is neither
necessary nor required under the
Sheet Metal Coverage. Chevrolet
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 Chevrolet Low Cab
Forward dealer as soon as possible.
Your owner manual has instructions
regarding the care of these items.
Vehicle Operation and Care
Considering the investment you
have made in your Chevrolet, we
know you will want to operate and
maintain it properly. We urge you to
follow the maintenance instructions
in your owner manual.
If you have questions on how to
keep your vehicle in good working
condition, see your Chevrolet Low
Cab Forward dealer, the place many
customers choose to have their
maintenance work done. You can
rely on your Chevrolet Low Cab
Forward dealer to use the proper
parts and repair practices.
Maintenance and Warranty
Service Records
Retain receipts covering
performance of regular
maintenance. Receipts can be very
important if a question arises as to
whether a malfunction is caused by
lack of maintenance or a defect in
material or workmanship.
A“Maintenance Record” is provided
in the maintenance schedule
section of the owner manual for
recording services performed.
The servicing Chevrolet Low Cab
Forward dealer can provide a copy
of any warranty repairs for your
records.
Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can fall
upon and adhere to painted
surfaces on your vehicle. This
damage can take two forms:
blotchy, ring-shaped discolorations,
and/or small irregular dark spots
etched into the paint surface.
