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 are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.

pad to sound the horn.

Climate Controls
With this system, you can control the heating, cooling
and ventilation in your vehicle. The system works best
if you keep your windows closed while using it.
Fan Knob
The knob on the left side of the climate control panel
regulates the fan speed. To turn the fan off, turn the
knob to OFF.
If the airflow seems very low when the fan is adjusted to
the highest setting regardless of the mode setting, your
passenger compartment air filter (if equipped) may need
to be replaced. See ªMaintenance Scheduleº and
ªPassenger Compartment Air Filterº in the Index.Driver's Temperature Lever
The lever on the left adjusts the air temperature on
the driver's side independent of the temperature set
by the passenger. Slide the lever upward to raise the
temperature. Slide the lever downward to lower
the temperature.
Passenger's Temperature Lever
The lever on the right adjusts the air temperature on
the passenger's side independent of the temperature
set by the driver. Slide the lever upward to raise the
temperature. Slide the lever downward to lower
the temperature.
Mode Knob
The knob on the right side of the control panel has
several settings to control the direction of airflow:
(Vent): This setting directs air through the
instrument panel outlets.
(Bi-level): This setting directs air two ways.
Half of the air is directed through the instrument panel
outlets. Most of the remaining air is directed through
the floor vents and a small amount to the windshield
defroster and side window outlets.

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.
