decrease with time and miles driven.

14 THINGS TO KNOW ABOUT THE NEW VEHICLE LIMITED 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. Cadillac
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.
Vehicle Operation and Care
Considering the investment you have
made in your Cadillac, 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 Cadillac dealer, the
place many customers choose to have
their maintenance work done. You can
rely on your Cadillac 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 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.
Although no defect in the factory
applied paint causes this, Cadillac will
repair, at no charge to the owner, the
painted surfaces of new vehicles
damaged by this fallout condition
within 12 months or 12,000 miles of
purchase, whichever comes first.
Warranty Coverage
–Extensions
Time Extensions : The New Vehicle
Limited Warranty will be extended
one day for each day beyond the first
24 hour period in which your vehicle
is at an authorized dealer facility for
warranty service. You may be asked to

including related diagnostic costs,
parts, and labor are covered by this
warranty.
Federal Emission Performance
Warranty
Some states and/or local jurisdictions
have established periodic vehicle
Inspection and Maintenance (I/M)
programs to encourage proper
maintenance of your vehicle. If an
EPA-approved I/M program is
enforced in your area, you may also be
eligible for Emission Performance
Warranty coverage when all three of
the following conditions are met:
.The vehicle has been maintained
and operated in accordance with
the instructions for proper
maintenance and use set forth in
the owner manual supplied with
your vehicle.
. The vehicle fails an EPA-approved
I/M test during the emission
warranty period. .
The failure results, or will result,
in the owner of the vehicle having
to bear a penalty or other
sanctions, including the denial of
the right to use the vehicle, under
local, state, or federal law.
GM warrants that your Cadillac dealer
will replace, repair, or adjust to
Cadillac specifications, at no charge to
you, any of the parts listed under
Emission Warranty Parts List 022,
which may be necessary to conform to
the applicable emission standards.
Non-Cadillac parts labeled “Certified
to EPA Standards ”are covered by the
Federal Emission Performance
Warranty.
California Emission Control

warranty that Cadillac provides for
your vehicle in accordance with the
California Air Resources Board.
Defects in material or workmanship in
Cadillac emission parts may also be
covered under the New Vehicle
Limited Warranty Bumper-to-Bumper

meets both of the following
requirements:

warranty regulations.*
