Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange or
different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into your
vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While You're
Parked (Automatic Transaxle)
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control system
off could allow dangerous exhaust into your
vehicle. See the earlier Caution under ªEngine
Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the fan is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
See ªBlizzardº in the Index.

Comfort Controls
With this system, you can control the heating, cooling
and ventilation in your vehicle.
Your vehicle also has the flow
-through ventilation
system described later in this section.
Climate Control System
Mode Knob
(Vent): This position directs the airflow though the
upper instrument panel outlets.
(Bi-Level): This position directs the airflow
through the upper instrument panel vents and toward
the floor.
(Floor): This position directs the airflow toward
the floor and through the right and left side vents. The
side vents can be shut off to allow for more air to be
directed toward the floor.
(Defog): This position directs the airflow
toward the floor, the windshield and the side windows.
The air also comes from both vents at the ends of the
instrument panel.
(Defrost): This position directs the airflow to the
windshield and side windows. The air also comes from
both vents at the ends of the instrument panel.
For maximum defrosting and defogging, adjust the
temperature knob to hot, use outside air mode and shut
off airflow to the outside instrument panel vents to
increase air through the side defroster vents.
Fan Knob
Turn the knob away from OFF to turn the system on.
Turn the knob toward HI to increase fan speed.

3-3
Temperature Knob
Turn the knob to change the temperature of the air
flowing from the system. Turn the knob clockwise to
increase the temperature. Turn the knob
counterclockwise to decrease the temperature.
(Recirculate): Press this button, located in the
center of the instrument panel to the left of the audio
system, to recirculate inside air through the comfort
control system. An indicator light in the button will
come on to let you know the feature is in use. Press the
button again to turn off recirculate and to circulate
outside air through the system. The indicator light will
go off. Recirculate is automatically turned off when the
climate control system mode knob is turned to defog or
defrost or is between modes.
Air Conditioning
A/C (Air Conditioning): Press the A/C button, located
in the center of the instrument panel to the left of the
audio system, to change your comfort control system to
air conditioning. An indicator light will come on when
the air conditioning is on. Air conditioning can also
control the humidity in your vehicle. The incoming air is
cooled and dehumidified.
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.
For normal cooling, press the A/C button and make sure
to use outside air. For faster cooling, also press the
recirculate button. Then move the mode knob to vent
and turn the temperature control knob counterclockwise.
Turn the fan knob to HI.
On days when it is raining or the humidity is high,
follow these dehumidifying steps instead of the cooling
directions. It will help clean windows that are cloudy
with moisture.
1. Press the A/C button.
2. Turn the mode knob to defrost. Recirculate will be off.
3. Turn the fan knob to HI and adjust the temperature
knob to a comfortable setting.

6-56 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.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.
