In cold weather, the system will delay turning on the fan
to avoid blowing cold air into the vehicle. The length of
the delay depends on the engine coolant temperature and
the outside temperature. Turning the right mode knob
will override this delay by turning off the automatic
mode and changing the fan speed.
Your automatic electronic climate control system has a
sun sensor located on the top of the instrument panel
that detects direct sunlight. To keep you and your
passengers comfortable, the system may supply cooler
air to the side of the vehicle toward the sun. Be careful
not to put anything over this sun sensor. The automatic
electronic climate control system may not operate
correctly if this sensor is covered.
To change the automatic electronic climate control
display from an English display to a metric display, push
the OFF button located in the Driver Information Center
(DIC) for two seconds. The display in the DIC will also
change from an English to a metric display. To return to
an English display, repeat the above procedure.Passenger Temperature Control (Option)
With this feature, the right
front seat passenger can
control the temperature
setting for his or her own
zone. To use this feature,
turn the knob on the
passenger's door clockwise
or counterclockwise to a
cooler or warmer setting.
The temperature can be set up to 8F (4C) cooler or
warmer than the main setting.

3-6 Comfort Controls Personalization
(If Equipped)
This feature enables up to two drivers to store and recall
comfort control settings for temperature, air delivery
mode and fan speed.
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 and put the
ignition in ACC (Accessory) or ON. The climate
control setting last chosen by the identified
driver (1 or 2) will be recalled.
To program a personal climate control setting, do
the following:
1. Choose a climate control setting for the driver
and if desired, for the passenger. See ªAutomatic
Electronic Climate Controlº and ªPassenger
Temperature Control (Option)º earlier in this section.
2. Adjust 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.
Air Conditioning
The air conditioner cools and dehumidifies the air inside
of the vehicle.
The air conditioning compressor is enabled in all
modes unless the air conditioning button is not selected
(the indicator light will not be illuminated). However,
the air conditioning compressor will not operate when
the outside temperature is below 34F (1C). When the
air conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off to maintain the desired
temperature and to help with fuel economy.

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.
~!(Fan): Press the up arrow on the fan button to
override the automatic fan control and increase the fan
speed in manual mode. Press the down arrow on the fan
button to override the automatic fan control and reduce
the fan speed in manual mode.
~TEMP! (Temperature): Press either arrow on the
TEMP button once to display your current temperature
setting in the digital display. Press the up arrow on the
TEMP button again to provide a warmer temperature
setting or press the down arrow on the TEMP button
again to provide a cooler temperature 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 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.
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.
To set the clock to the time of an FM station
broadcasting Radio Data System (RDS) information,
press and hold HR and MN at the same time until
UPDATED appears on the display. If the time is not
available from the station, NO UPDATE will appear on
the display instead.

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.
