Running Your Engine While
You're Parked
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).
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.
Horn
You can sound the horn by pressing the center of your
steering wheel.

3-5 Dual Automatic ComforTemp Climate
Control (If Equipped)
With this system, you set a temperature. You can then
either let the system automatically control airflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best if you
keep your windows closed while using it.
The vehicle's interior will warm up or cool down at the
same rate no matter which temperature you choose. For
example, if you set the system at 90
F (32
C) it will not
heat any faster than if you had set it at 70
F (21
C).
It will just continue to heat longer.Automatic Control
For the most efficient operation, you should set the
system temperature and push the driver's temperature
knob for automatic operation. The word AUTO will be
shown in the display. The system will select the best fan
speed and airflow settings to keep you comfortable.
The air conditioning compressor will run if the outside
temperature is above 32
F (0
C). You may notice a
delay of two to three minutes before the fan comes on
when you start your vehicle in cool weather.
Driver's Temperature Control
The driver's temperature knob sets the temperature for
the system when the passenger's temperature setting is
in neutral. If the passenger's temperature setting is not in
neutral, the driver's temperature knob sets the
temperature for the driver only.
Turn the knob clockwise to raise the temperature and
counterclockwise to lower the temperature. The display
will show the temperature briefly, then the outside
temperature will be displayed.
If you push the temperature knob for automatic
operation, the system will control the fan speed and
air temperature.

6-49 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.
