Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger’s side of the vehicle, underneath
the air inlet grille.
The lter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/lter, it may need to be changed periodically to
ensure system performance. For information on how
often to change the passenger compartment air
lter, seeScheduled Maintenance on page 6-4.
To change the passenger compartment air lter, use the
following steps:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the vehicle hood.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway to center.5. Remove the air inlet grille retainers.
6. Remove the air inlet grille.
7. Remove the old passenger compartment air lter.
8. Reverse the steps to install the new air lter.
For the type of lter to use, seeNormal Maintenance
Replacement Parts on page 6-13.

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance.
(This applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) 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 signicantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
