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.

Comfort Controls
This section tells you how to make your air system work
for you. With this system, you can control the heating,
cooling and ventilation in your vehicle.
Your vehicle also has a flow
-through ventilation system
described later in this section.
Your vehicle may be equipped with a passenger
compartment air filter. For more information, see
ªPassenger Compartment Air Filterº in the Index.
Standard Climate Control System
FAN: The left knob regulates the force of the air coming
through the system. Push this knob to turn the fan on
and off. Turn the knob clockwise toward HI to increase
the fan speed and counterclockwise toward LO to
decrease the fan speed.The fan must be on in order for
the air conditioning compressor to run.
TEMP (Temperature): The right knob regulates the
temperature of the air coming through the system. Turn
it toward the blue area for cooler air. Turn it toward the
red area for warmer air.

When the weather is cool or damp, operating in
RECIRC for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog,
switch back to outside air by turning off RECIRC, select
either defog or FRONT defrost mode and increase the
fan speed. To avoid refogging of the windows, minimize
your use of recirculation under these conditions and turn
the A/C on to help dehumidify the air.
A/C (Air Conditioning): Press this button to turn
the air conditioning compressor on and off. The system
will cool and dehumidify the air inside your vehicle. If
your comfort control system is off, you can also turn it
back on in vent mode by selecting the A/C button.
Even though A/C is not selected, in FRONT defrost
mode the A/C compressor will run automatically at
temperatures over approximately 40
F (4
C) to
improve windshield clearing performance.
Electronic Climate Control System (Option)
DRIVER (Driver's Side Temperature): The knob
on the left is used to change the temperature of the air
coming through the system on the driver's side of the
vehicle. Push this knob to turn the system on and off.
Turn the knob toward the blue area to decrease the set
temperature. Turn the knob toward the red area to
increase the set temperature. When this knob is
adjusted, the word DRIVER will be displayed
under the set temperature.
When the passenger's set temperature is not active,
this knob controls both the driver's and passenger's side,
and both DRIVER and PASS will be displayed under the
set temperature.

3-11 Comfort Controls Personalization
(If Equipped)
This feature enables up to two drivers to store and recall
comfort control settings for the temperature, fan speed
and the direction of the airflow.
The memory buttons (1 or 2) for this feature are located
on the driver's door panel and correspond to the
numbers (1 or 2) found on the back of each remote
keyless entry transmitter.
To recall comfort settings, press the unlock button on
the remote keyless entry transmitter before entering
your vehicle.
If you enter your vehicle without using the remote
keyless entry, the settings for the last identified driver
will be recalled when you put the ignition in
ACCESSORY or RUN.
To program a personal choice climate control setting,
do the following:
1. Choose a temperature setting for the driver and if
desired, for the passenger. See ªElectronic Climate
Control System (Option)º earlier in this section.
2. Adjust the fan speed and the direction of the airflow.3. Locate the memory buttons on the driver's
door panel.
4. Press a memory button (1 or 2) until you hear two
beeps. The beeps confirm that your selection has
been saved and can now be recalled.
Follow these steps each time you want to change the
stored settings.
For more information on the memory feature, see
ªMemory Seat and Mirrorsº in the Index.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Power (RAP)º in the Index.

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.
