2004 CHEVROLET EPICA climate control

Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or 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. 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.
Select one of these available modes from the
right knob.
É(Defog):This mode directs most of the air to the
windshield and the floor outlets. A small amount of air is
also directed to the outboard outlets for the side
windows.
To help clear the side windows quickly, do the following:
1. Select the bi-level mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the temperature.
0(Defrost):This mode directs the air to the
windshield and the outboard outlets for the side
windows.
To help clear the windshield quickly, do the following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.
Do not drive the vehicle until all windows are clear.

To cancel defrost, press the MODE or AUTO buttons.
If you press the AUTO button, the system will operate
automatically.

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
selection width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system developed
by the Unites 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.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For example, a tire graded 150 would wear one and
a 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.
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 specified 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.
