2004 CHEVROLET IMPALA climate control

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
insure 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 air deector grille in the compartment.
8. Remove the old passenger compartment air
lter.
9. Reverse the steps to install the new air lter.
For the type of lter to use, seeNormal Maintenance
Replacement Parts on page 6-13.

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.
Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specied indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inated and not
overloaded. Excessive speed, underination, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
