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).
If you have four-wheel drive, your vehicle will
be free to roll
-- even if your shift lever is in
PARK (P)
-- if your transfer case is in
NEUTRAL. So be sure the transfer case is in a
drive gear
-- not in NEUTRAL. See ªFour-Wheel
Drive (Automatic Transfer Case)º in the Index.
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.
Standard Climate Control System
Fan Knob
The knob on the left side of the climate control system
control panel regulates the fan speed. To increase
airflow, move the knob clockwise. To decrease airflow,
move it counterclockwise.Temperature Knob
The middle knob on the control panel lets you select the
relative temperature of the air flowing into the passenger
area of your vehicle. Move the knob clockwise toward
the red area for warmer air. Move the knob
counterclockwise toward the blue area for cooler air.
Mode Knob
The right knob on the control panel allows you to
choose the direction of air delivery.
OFF: This mode turns the system off. Some outside air
will still enter the vehicle whenever the vehicle is
moving forward.
MAX A/C (Maximum Air Conditioning): This mode
provides maximum cooling with the least amount of
work. MAX A/C recirculates much of the air inside your
vehicle so it cools quickly. This setting directs most of
the air through the instrument panel vents and a small
amount through the floor ducts.

3-4 Heating
The heater works best if you keep your windows closed
while using it. On cold days, use floor mode with the
temperature knob turned clockwise. Blend mode is
useful in cool weather when you have fog or ice on the
windshield or side windows.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See ªEngine Coolant Heaterº in the Index.
Defogging and Defrosting
On cool, humid days, use blend mode to keep the
windshield and side windows clear.
Use defrost mode to remove fog or ice from the
windshield quickly in extreme humid or cold conditions.
Turn the temperature knob clockwise and move the fan
knob toward high.
Rear Window Defogger (If Equipped)
If your vehicle has this
feature, the rear window
will have lines that warm
the glass.
For best results, clear the window of as much snow or
ice as possible before using the rear window defogger.
To turn on the rear window defogger, find the button
marked REAR with the defog symbol on the lower right
corner of your climate control system. Press the button
until the light in the button comes on, then release it. It
will only work if the ignition switch is turned to RUN.
Pressing the REAR button on your climate control
system will also activate your heated outside mirrors
(if equipped). This will help to keep ice and snow from
collecting on your mirror surfaces.

3-66
AM FM: Press this button to listen to the radio
when a tape is playing. The inactive tape will remain
in the player.
CD AUX (Auxiliary): Press this button to play a tape
when listening to the radio. The lighted arrow will
appear next to the symbol and show the direction of play
when a tape is active.
Remote Cassette Tape Player Controls
The following functions are controlled by the remote
cassette tape player:
PROG (Program): Press this button on the remote
player to go from one side of the tape to the other.
EJECT: Press this button on the remote player to
remove the tape. EJECT can be used with either the
ignition or radio off. Also, you must press EJECT before
loading a cassette with the radio off to allow loading.Console-Mounted CD Changer
(If Equipped)
If your vehicle is equipped with the console-mounted
compact disc changer, it is located in the center console.
Some vehicles may have this feature mounted in the
front console just below the climate control system
and accessory power outlets. With the compact disc
changer, you can play up to six discs continuously.
Normal size discs may be played using the slots
supplied in the magazine.

6-51 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.
