Running Your Engine While You're
Parked (Automatic Transmission)
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.
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Four-wheel drive vehicles with the transfer case
in NEUTRAL will allow the vehicle to roll,
even if your shift lever is in PARK (P). So, be
sure the transfer case is in a drive gear
-- not in
NEUTRAL. Always set your parking brake.
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº 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
Airflow Lever
(Vent): This position directs the airflow through the
instrument panel vents.
(Bi-level): This position directs air through the
instrument panel vents and toward the floor.
(Floor): This position directs air toward the floor
and through the right and left side vents. The side vents
can be shut off by closing the thumbwheel to allow for
more air to be directed toward the floor.
(Defog): This position directs air toward the floor,
the windshield and side windows. The air also comes
from both vents at the ends of the instrument panel
if the thumbwheel below them is in the open position.
The air conditioning compressor will run automatically
in this setting without pressing A/C.
(Defrost): This position directs air to the
windshield and side windows. The air also comes
from both vents at the ends of the instrument panel
if the thumbwheel below them is in the open position.
The air conditioning compressor will run automatically
in this setting without pressing A/C.
For maximum defrosting and defogging, adjust the
temperature control lever to the hot end, move the
air intake lever to outside air and shut off airflow to
the outside instrument panel vents by closing the
thumbwheels to increase air through the side
defroster vents.

Fan Lever
Slide the lever located on the upper right side away from
OFF to turn the system on. Move the lever toward the
fan symbol to increase the fan's speed.
Temperature Lever
Slide the lever located on the lower left side to change
the temperature of the air flowing from the system.
Move it to the right for warmer air and to the left for
cooler air. Without air conditioning, the air temperature
cannot be less than the outside air temperature.
Air Intake Lever
(Recirculate): Choose this position to recirculate
the inside air through the comfort control system.
(Outside Air): Choose this position to circulate
outside air through the comfort control system.
Air Conditioner Controls
The air conditioning
system uses the same
controls as described
previously. The function
of each lever is explained
under ªClimate Control
Systemº in this part.
When on, the incoming
air will be cooled
and dehumidified.
A/C (Air Conditioning): Press the A/C button to
change your comfort control system to air conditioning.
A light will come on in the button when the air
conditioning is on. Air conditioning can also control
the humidity in your vehicle.
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.

6-53 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.
