Press this button on the fan knob to turn the recirculation
mode on or off. An indicator light on the button will
come on to let you know the recirculation mode
is activated.
Recirculation is only available in the bi-level and vent
modes. If you push the recirculation button while
the system is in any other mode, the light on the button
will ¯ash to indicate that recirculation is not available.
Mode Knob
The right knob on the control panel is used to direct the
air¯ow inside your vehicle. Turn the knob to select
one of the following modes:
H(Vent):Select this mode to direct air to the
instrument panel outlets.
)(Bi-Level): Select this mode to direct approximately
half of the air to the instrument panel outlets, and the
remaining air to the ¯oor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the ¯oor outlets.
6(Floor): Select this mode to direct air to the ¯oor
outlets. Recirculation does not work in this mode.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to clear
fog or frost from your windshield and side windows.
Use the defog mode to clear the windows of fog
or moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield
more quickly. For best results, clear all snow and
ice from the windshield before defrosting.
/(Floor/Defog): This mode directs half of the air
to the windshield and the side window outlets and the
other half to the ¯oor outlets. When you select this
mode, the system runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
Recirculation is not available in this mode.
0(Defrost): This mode directs most of the air to the
windshield, with some air directed to the side window
outlets and the ¯oor outlets. When you select this
mode, the system runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
Recirculation is not available in this mode.

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 speci ed 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 signi cantly 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 speci ed 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.
