BUICK LACROSSE 2011 Get To Know Guide

Things to Know About the New Vehicle Limited Warranty 17
Pre-Delivery Service
Defects in the mechanical,
electrical, sheet metal, paint, trim,
and other components of your
vehicle may occur at the factory or
while it is being transported to the
dealer facility. Normally, any defects
occurring during assembly are
identified and corrected at the
factory during the inspection
process. In addition, dealers inspect
each vehicle before delivery. They
repair any uncorrected factory
defects and any transit damage
detected before the vehicle is
delivered to you.
Any defects still present at the time
the vehicle is delivered to you are
covered by the warranty. If you find
any defects, advise your dealer
without delay. For further details
concerning any repairs which the
dealer may have made prior to you
taking delivery of your vehicle, ask
your dealer.
Production Changes
GM and GM dealers reserve the
right to make changes in vehicles
built and/or sold by them at any time
without incurring any obligation to
make the same or similar changes
on vehicles previously built and/or
sold by them.
Noise Emissions Warranty for
Light Duty Trucks Over
10,000 LBS Gross Vehicle
Weight Rating (GVWR) Only
GM warrants to the first person who
purchases this vehicle for purposes
other than resale and to each
subsequent purchaser of this
vehicle, as manufactured by GM,
that this vehicle was designed, built,
and equipped to conform at the time
it left GM's control with all applicable
United States EPA Noise Control
Regulations.This warranty covers this vehicle as
designed, built, and equipped by
GM, and is not limited to any
particular part, component,
or system of the vehicle
manufactured by GM. Defects in
design, assembly, or in any part,
component, or vehicle system as
manufactured by GM, which, at the
time it left GM's control, caused
noise emissions to exceed Federal
Standards, are covered by this
warranty for the life of the vehicle.

18 Emission Control Systems Warranty
The emission warranty on your
vehicle is issued in accordance with
the U.S. Federal Clean Air Act.
Defects in material or workmanship
in GM emission parts may also be
covered under the New Vehicle
Limited Warranty
Bumper-to-Bumper coverage. There
may be additional coverage on GM
diesel engine vehicles. In any case,
the warranty with the broadest
coverage applies.
What Is Covered
The parts covered under the
emission warranty are listed under
Emission Warranty Parts List on
page 23
How to Determine the
Applicable Emissions Control
System Warranty
State and Federal agencies may
require different emission control
system warranty depending on:
.Whether the vehicle conforms to
regulations applicable to light
duty or heavy duty emission
control systems.
.Whether the vehicle conforms to
or is certified for California
regulations in addition to U.S.
EPA Federal regulations.
All vehicles are eligible for Federal
Emissions Control System Warranty
Coverage. If the emissions control
label contains language stating the
vehicle conforms to California
regulations, the vehicle is also
eligible for California Emissions
Control System Warranty Coverage.

Federal Emission Defect Warranty
GM warrants to the owner the
following:
.The vehicle was designed,
equipped, and built so as to
conform at the time of sale with
applicable regulations of the
Federal Environmental
Protection Agency (EPA).
.The vehicle is free from defects
in materials and workmanship
which cause the vehicle to fail to
conform with those regulations
during the emission warranty
period. Emission related defects in the
genuine GM parts listed under the
Emission Warranty Parts List,
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 of the following
three 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 dealer will
replace, repair, or adjust to GM
specifications, at no charge to you,
any of the parts listed under the
Emission Warranty Parts List on
page 23 which may be necessary to
conform to the applicable emission
standards. Non-GM parts labeled
“Certified to EPA Standards” are
covered by the Federal Emission
Performance Warranty.

your vehicle line as soon as a
problem exists. The warranted
repairs should be completed in a
reasonable amount of time, not to
exceed 30 days.As the vehicle owner, you should
also be aware that GM may deny
warranty coverage if your vehicle or
a part has failed due to abuse,
neglect, improper or insufficient
maintenance, or modifications not
approved by GM.

your rights and responsibilities
under these warranties, you should
