To program a personal choice climate control setting,
do the following:
1. Choose a temperature setting for the driver and if
desired, for the passenger. See ªDual Automatic
ComforTemp
Climate Controlº and ªPassenger
Climate Controlº earlier in this section.
2. Adjust the fan speed and the direction of the airflow.
3. Locate the memory buttons on the driver's
door panel.
4. Press a memory button (1 or 2) until you hear two
beeps. The beeps confirm that your selection has
been saved and can now be recalled.
Follow these steps each time you want to change the
stored settings. For more information on the memory
feature, see ªMemory Seat and Mirrorsº in the Index.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
If you have the electronic touch system, for quick
cool
-down on very hot days, use maximum air
conditioning with the temperature and fan speed
adjusted to COOL and HIGH. If this setting is used
for long periods of time, the air in your vehicle may
become too cold and dry.
For normal cooling on hot days, use Normal and
adjust the temperature and fan speed for your comfort.
If Recirculation is selected while in the Normal air
conditioning mode, the system works like maximum
air conditioning and recirculates the air.

Ventilation Tips
Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.
Keep the air path under the front seats clear
of objects. This helps air to circulate throughout
your vehicle.
When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow air
that is too cool. Once the vehicle is moving again,
the system will try to maintain the set temperature
inside your vehicle.
When you start your vehicle and the EXT display
flashes (Dual Automatic ComforTemp system only)
for some time, the system may need repair. See
your dealer.Steering Wheel Controls for Climate
Control (If Equipped)
If your vehicle has this feature, you can control the
temperature function by using the buttons located on
your steering wheel.
Press the TEMP
(Temperature) up arrow
to increase the temperature
and the TEMP
(Temperature) down
arrow to decrease
the temperature.
6-50 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 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.
