Manual Operation
You may override the automatic airflow distribution by
turning the AUTO
-PUSH knob. After you turn this
knob, the comfort setting will be displayed for five
seconds, then the outside temperature will be displayed.
The fan control will remain in the automatic control
mode unless you turn the AUTO FAN knob to select
a manual fan speed.
PANEL: This setting directs airflow through the
upper air outlets located in the instrument panel.
BI-LEVEL: This setting directs the airflow
through both the panel air outlets and the lower floor
outlets. There is also a small amount of air directed to
the front defroster and the side window defrosters.
FLOOR: This setting directs most of the airflow
to the lower floor outlets with some airflow directed to
the side window defrosters. There is also a small amount
of airflow directed to the front defroster.
DEFOG: This setting directs the majority of
the airflow to the lower floor outlets and the front
defroster. A small amount of airflow is directed to the
side window defroster outlets. This mode can be useful to remove the moisture from the inside of the windshield
when the outside temperature is cold or the humidity is
high. Be sure the A/C indicator light comes on to allow
the air compressor to come on automatically to help
dehumidify the air.
DEF (Defrost): This setting directs the majority
of the airflow to the windshield with some airflow to
the side window defrosters and lower floor outlets.
To increase the fan speed, turn the AUTO FAN knob
clockwise. If defrost is selected from AUTO mode,
your automatic electronic climate control system will
automatically increase the defrost outlet temperature
and fan speed. For maximum front defrost performance
under extreme icing or frosting conditions, increase the
temperature setting to 90F (33C) and increase
the fan speed to high.
Even though A/C is not selected, in front defrost
mode the A/C compressor will run automatically
at temperatures over approximately 40F (4C) to
improve windshield clearing performance. This
dehumidifies the air to help dry the windshield.
Even though the compressor may be running,
the A/C indicator light will not come on in front
defrost unless you select A/C.

3-10 Steering Wheel Controls for Climate Control
Some heating and cooling
controls can be adjusted
at the steering wheel.
Other touch controls
also operate some audio
controls. See ªAudio
Steering Wheel Controlsº
later in this section.
Press the upper part of the fan symbol button to override
the automatic fan control and increase the fan speed.
Press the lower part of the fan symbol button to override
the automatic fan control and reduce the fan speed.
Press either arrow on the TEMP button once to display
your current comfort setting in the digital display. Press
the upper part of the TEMP button again to provide a
warmer comfort setting or press the lower part of the
TEMP button again to provide a cooler comfort setting.
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 its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Setting the Clock
Press and hold HR until the correct hour appears. The
letters AM or PM will appear on the display. Then, press
and hold MN until the correct minute appears. The clock
may be set with the ignition on or off. In addition, the
clock can also be automatically set, when tuned to an
RDS station that is broadcasting time, by pressing and
holding the HR and the MN button at the same time.
The display will show TIME UPDATED. If there is no
time available, NO UPDATE will be displayed.

3-24 Theft-Deterrent Feature
THEFTLOCK is designed to discourage theft of
your radio. It works by using a secret code to disable
all radio functions whenever battery power is removed
and the radio is placed in a different vehicle. This
feature requires no user input to be activated. It is
automatically armed when it is put into the vehicle for
the first time.
When the radio is turned off, the blinking red light
indicates that THEFTLOCK is armed.
If THEFTLOCK is activated, your radio will not operate
if stolen. The radio will display LOC and a red LED
indicator light will come on above the THEFTLOCK
logo to indicate a locked condition. If this occurs,
the radio will have to be returned to the dealer.
Audio Steering Wheel Controls
With this feature, you can control certain radio functions
using the buttons on your steering wheel.
Some steering wheel
controls operate climate
controls. See ªSteering
Wheel Controls for
Climate Controlº earlier
in this section.
VOL: Press the up or down arrow to increase or
decrease volume.
SEEK: Press this button to tune to the next strong
radio station. When playing a cassette tape or compact
disc, press SEEK to hear the next selection. There must
be at least a three
-second gap between selections on a
cassette tape.
PROG: Press this button to tune in the next preset
radio station. When playing a cassette tape, press PROG
to hear the other side of a tape that is playing. When
listening to a disc in the CD changer, press PROG to
select the next loaded disc.

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.
