New Vehicle Limited Warranty 11
Damage Due to Contaminated or
Poor Quality Fuel
Poor fuel quality or incorrect fuel
may cause driveability problems
such as hesitation, lack of power,
stall, or no start. It may also render
gauges inoperable or degrade
functionality for components such
as spark plugs, oxygen sensors,
and the catalytic converter. Damage
from poor fuel quality, water
contamination, incorrect diesel fuel
or gasoline may not be covered.
It is recommended that gasoline
meet specifications which were
developed by automobile
manufacturers around the world
and contained in the World-Wide
Fuel Charter which is available
from the Alliance of Automobile
Manufacturers at
www.autoalliance.org/
fuel_charter.htm. Gasoline meeting
these specifications could provide
improved driveability and emission
control system performance
compared to other gasoline.Please refer to your Owner Manual
under
“Fuel” , for additional
recommendations, including the use
of TOP TIER Detergent Gasoline.
Additional information can also be
found at: www.toptiergas.com/
index.html.
Damage Due to Impact, Use,
or the Environment
Windshield or glass cracks, chips or
scratches due to impact are not
covered. Windshield cracks will be
covered for the first 12 months,
regardless of mileage if caused by
defects in material or workmanship.
Lights, lens, mirrors, paint, grill,
moldings and trim are not covered
for cracks, chips, scratches, dents,
dings and punctures or tears as a
result of impact with other objects or
road hazards. In addition, cracks,
chips, scratches or other damage to
the face of a radio or instrument
cluster from impact or foreign
objects is not covered. Maintenance
All vehicles require periodic
maintenance. Maintenance
services, such as those detailed in
the owner manual are the owner's
expense. Vehicle lubrication,
cleaning, or polishing are not
covered. Failure of or damage to
components requiring replacement
or repair due to vehicle use, wear,
exposure, or lack of maintenance is
not covered.
Items such as:
.Audio System Cleaning
.Brake Pads/Linings
.Clutch Linings
.Coolants and Fluids
.Filters
.Keyless Entry (or other remote
transmitter/receiver batteries) *
.Limited Slip Rear Axle Service

whichever comes first, California
Emission Control System
Warranty coverage.
.(**) 8 years/80,000 miles,
whichever comes first, Federal
Emission Control System
Warranty coverage. (Also
applies to California certified
light duty and medium duty
vehicles.)
.(*) and (**) are 8 years/
100,000 miles, whichever comes
first, for California LEV2 vehicles
equipped with option code NUA.
All listed parts 15 years/
150,000 miles, whichever comes
first, on California PZEV (NU6)
vehicles registered in a PZEV state.
The Emission Control System
Warranty obligations do not apply to
conditions resulting from tampering,
abuse, neglect, or improper
maintenance; or any other item
listed under “What Is Not Covered”
under New Vehicle Limited Warranty
on page 4. The “Other Terms”
presented under New Vehicle
Limited Warranty on page 4 also
apply to the emission related
warranties.
