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 Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch 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.

Comfort Controls
With this system, you can control the heating and
ventilation in your vehicle. If you have the air
conditioning option, you can also control cooling.
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.
DEFOG: This position directs air toward the
floor, the windshield and side windows.
DEFROST: This position directs air to the
windshield and side windows.
Fan Control Lever
Slide the lever away from OFF to turn the system on.
Move the lever toward the fan symbol to increase the
fan's speed.
Temperature Control Lever
Slide the lever 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
optional air conditioning, the air temperature can't be
less than the outside air temperature.
Air Intake Lever
CIRCULATE: Choose this position to circulate
outside air through the comfort control system.
RECIRCULATE: Choose this position to
recirculate the inside air through the comfort
control system.

3-3 Air Conditioner Controls (If Equipped)
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. The incoming air is
cooled and dehumidified
instead of being heated.
Push the A/C button to change your comfort control
system from heating to air conditioning. A light will
come on when the air conditioning is on. The A/C
button 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.For normal cooling, push the A/C button and move the
air intake lever to CIRCULATE. For faster cooling,
move the lever to RECIRCULATE. Then move the
airflow lever to VENT, the temperature control lever
toward the left and the fan control lever toward the
fan symbol.
On days when it is raining or the humidity is high,
follow these dehumidifying steps to help clean windows
that are cloudy with moisture. Push the A/C button.
Move the air intake lever to CIRCULATE. Move the
airflow lever to DEFROST and the fan control lever
toward the fan symbol. Adjust the temperature control
lever to a comfortable setting.
Heating
For the quickest results, move the air intake lever to
RECIRCULATE. Move the airflow lever to FLOOR, the
temperature control lever toward the right for warmer
air and the fan control lever toward the fan symbol. You
should switch to CIRCULATE once in a while to avoid
stale air and cloudy windows.

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.Temperature
-- A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance
on the laboratory test wheel than the minimum required
by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
