Maintenance
DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance a ccording to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on the tire sidewall
between tread shoulder an d maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested un der controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.
■Uniform Tire Quality Grading
■Treadwear
1 Uniform Tire Quality Grading
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.

Maintenance
Heating and Cooling System*/Climate Control System* Maintenance
Air Conditioning
To ensure proper and safe operation, the Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant system only be serviced by trained and
certified technicians.
Never repair or replace the air conditioni ng evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The heating and cooling system*/climate control system* is equipped with a dust
and pollen filter that collects pollen, dust, and other debris in the air. The
Maintenance Minder
TM messages will let you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Heating and Cooling System*/Climate Control System*
Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
Air Conditioner label is found under the hood: 2 Safety Labels P. 71
