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.

Ultrasonic Rear Parking
Assist (URPA)
Ultrasonic Rear Parking Assist can help you to
determine how close an object is to your rear bumper
within a given area, making parking easier.
The URPA display is
located inside the vehicle,
on the passenger's side rear
upper trim panel. It has
three color
-coded lights that
can be seen through the
rearview mirror or by
turning around.
URPA can be disabled by
pressing the URPA on/off
button located near the
climate control system
and radio.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses how
close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When shifting into REVERSE (R) and an
object is detected, one of the following will occur:

Comfort Controls
Electronic Climate Control System
Fan Knob
The knob on the left side of the electronic climate control
panel is used to regulate the fan speed. To manually
increase airflow, move the knob clockwise. To manually
decrease airflow, move it counterclockwise.
OFF: If the knob is in OFF, outside air will still enter
the vehicle, and will be directed based on the position of
the mode knob.
AUTO: If the knob is in AUTO, the fan speed will vary
as the system maintains the selected temperature.
When both the fan knob and mode knob are in the AUTO
position, the system will then automatically maintain the
desired cabin temperature as selected by the temperature
knob. Manual operation is also available.Temperature Knob
The middle knob on the control panel is used to select
the desired air temperature in your vehicle. This knob
will allow you to adjust the interior air temperature
independent of the mode knob setting. Move the knob
clockwise toward 82 for warmer air. Move the knob
counterclockwise toward 66 for cooler air. When the
system is set for automatic operation, sensors will
control the fan speed.
Full Hot: If you turn the temperature knob past 82, the
system will go into the ªfull hotº mode. The system will
remain at that maximum heating setting and the fan will
blow at the speed to which the fan knob is set. If the fan
is in AUTO, it will run at full speed.
Full Cold: If you turn the temperature knob past 66, the
system will go into the ªfull coldº mode. The system
will remain at that maximum cooling setting and the fan
will blow at the speed to which the fan knob is set. If the
fan is in AUTO, it will run at full speed.

Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for you
by placing the system in AUTO mode. See ªMode
Knob
- Automatic Operationº earlier in this section.
(Vent): This setting directs most of the air through
the instrument panel outlets and a small amount through
the floor outlets.
(Bi-level): This setting delivers air through
the floor outlets as well as the instrument
panel outlets.
(Floor): This setting directs most of the warmed
air through the floor outlets and some air through the
windshield defroster outlets.
(Blend): This setting divides airflow equally
between the floor outlets and the windshield defroster
outlets. The air conditioning compressor may run to
dehumidify the air to prevent window fogging.
(Defrost): This setting directs most air through
the windshield defroster outlets and some through the
floor outlets. The air conditioning compressor may run
to dehumidify the air to prevent window fogging. When
using the defrost mode with auto fan speed selected, the
fan speed may be higher than normal.
(Outside air): Press this button, located under
the fan knob, to use outside air. Using outside air will
limit stale air odors and help to prevent excessively
humid interior air (from wet boots or clothing or
maximum passenger loads) from being redirected onto
windows.
Pressing the outside air button will cancel the
recirculation button and AUTO mode of the airflow.
Pressing outside air will return the system to auto mode.
(Recirculation): Press this button to limit the
amount of outside air entering the vehicle to a very
small amount. This will be helpful to limit odors
entering the vehicle and will assist in reaching comfort
in very hot temperature conditions. Pressing
recirculation will cause the system to recirculate interior
air continuously and may cause the vehicle windows
to fog if the passenger compartment floor is
excessively wet.

3-6 Rear Air Conditioning and Heating Systems
with Electronic Climate Control System
(Without Sunroof)
Front Control
Rear Control
With this system the rear passengers can control the air
temperature, air flow and air speed. The climate control
has three knobs.To adjust the airflow speed, turn the fan knob located on
the left side of the control panel to the desired setting.
The system can be controlled from the front controls as
well as the rear controls. Choosing AUTO from the front
will control the rear settings. Choosing OFF from the
front control will also turn off the rear climate control.
When the front control is set to REAR, the rear controls
can be used by rear seat passengers.
To adjust the air temperature on either control panel,
turn the temperature knob on the center of the control
panel. For warmer air, turn the knob clockwise
toward 82. Turn the knob counterclockwise toward 66
for cooler air.
To regulate the airflow direction, adjust the right knob
on the control panel. Turn the knob clockwise for floor
vent airflow or counterclockwise for headliner vent
airflow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The knob
can be set to any blend setting.

6-54 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.
