Downloaded from www.Manualslib.com manuals search engine Running Your Engine While You’re
Parked (Automatic Transmission)
It’s better not to park with the engine running. But if you
ever have to, here
are some things to know.
Idling the engine with the climate control system
off could allow dangerous exhaust into your
vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if
the fan switch 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
“Blizzard” in the Index.) 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 “Shifting Into
PARK (P)” in the Index.

Downloaded from www.Manualslib.com manuals search engine Automatic Electronic Dual Climate Control System
(If Equipped)
Your vehicle may be equipped with a Dual Zone
Electronic Climate Control System. This system can
automatically adjust and control temperature output, fan
speed, air delivery mode, air conditioning operation and
air intake. You can use the AUTO (automatic) setting or
override the automatic operation with manual control
settings. The control settings will be remembered each
time you turn the ignition
off and restart in the same
settings. You can use the Memory option to store and
recall your settings. (See “Memory” in the Index.)
Digital Display
The digital display shows readings in Fahrenheit or Celsius
by pressing the EM button (EnglisWMetric) on the Driver
Information Center @IC). When you
start the vehicle, the
display will show the current fan speed, air delivery mode
and the driver-set temperature for approximately five
seconds and then show the outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the display. If you have
selected a manual fan speed, then the fan symbol will
appear on the display.
If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.
Driver Set Temperature Knob
The DRIVER knob changes the temperature on the
driver’s and passenger’s side of the vehicle. Turn the
knob to the right to increase the temperature and to the
left to decrease the temperature. Whenever you turn this
knob, the temperature will be displayed for
approximately five seconds along with the current fan
speed and air delivery mode.
3-4

Downloaded from www.Manualslib.com manuals search engine As the interior of the vehicle warms up to your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler.
If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically
DEFOG or BI-LEVEL).
A ljpical Hot Weather Example:
Your vehicle has been parked outside all day in hot
weather (above
7OoF/ 21 O C) and you have set the driver
temperature at
73 OF (23 "C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The blower
will start at a low speed momentarily to push the hot air
to the floor of the vehicle and then go to a higher blower
speed with cold airflow out of the instrument panel
outlets.
A small amount of airflow will continue through
the lower ducts to cool the
floor area.
The air intake may start in the recirculated mode for
maximum cooling performance.
As the interior of the
vehicle cools down to your comfort set temperature, the
fan speed will decrease and the temperature output may
become warmer. The air intake may shift from
recirculation to fresh air mode.
If the interior continues to
cool due to a decrease,,,in the amount of heat the
vehicle is absorbing from the sun or a decrease
in the
outside temperature, the system could switch to other air
delivery modes (typically BI-LEVEL or DEFOG).
Manual Settings
With the Dual Zone Electronic Climate Control, there
are several manual settings you can use to control the
system and override the
AUTO operation. You can
program the fan speed,
air delivery mode, air intake
mode and control the air conditioning operation using
these settings. The system will still determine the
temperature output level based on the driver-set
temperature and the passenger temperature offset.
% FAN SPEED: Press the button with the fan switch
on it to manually lock
in the current fan speed and to
stop the automatic fan speed control. Pressing the
arrows will delete
AUTO from the digital display. The
fan graphics with the fan speed bars will be shown.
To
increase the fan speed so that more air flows into the
vehicle, press the
UP arrow on the fan switch. To
decrease the fan speed and airflow, press the DOWN
arrow. The
AUTO button must be pressed to return to
the automatic fan control.

Downloaded from www.Manualslib.com manuals search engine MODE: Press the MODE button to manually lock in the
current air delivery setting and to stop the automatic
mode control. Pressing the MODE button will delete
AUTO from the digital display and the mode graphics
will be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed to
return to the automatic mode selection.

UPPER: This setting directs most of the air
through the instrument panel outlets and a very small amount to the lower outlets.
+# BI-LEVEL: This setting directs air into your
vehicle in two ways. Cooler air is directed toward your upper body through the instrument panel outlets, while
warmer air is directed through the lower outlets.
+# LOWER: This setting directs most of the air to
the floor area and some of it toward the windshield and
side window vents.
+’, DEFOG: This setting divides the air between
the windshield and lower outlets and a small amount
toward the side window vents. This is useful when fog
appears
on the windshield or side glass due to rain or
snowy conditions.

Mode Buttons
These buttons control climate control OWOFF, air
intake, front defrost, rear defrost and the air
conditioning operation.
OFF: Press the OFF button to turn off the climate
control system.
This is the only setting that fully shuts
off the fan. The digital display will show only the
outside temperature. You can still adjust the driver set
temperature, the passenger temperature offset and the
air
intake mode while in OFF.
a A/C: This button turns the air conditioning
compressor on or
off, except in the FRONT defrost
mode. The light on the
A/C button will come on when
the compressor is operating in either the automatic or
manual mode. The air conditioning may also be forced
off at high engine speeds. The light on the A/C button
will flash
if pressed when air conditioning operation is
not allowed.

Downloaded from www.Manualslib.com manuals search engine Sensors
The Dual Zone Electronic Climate Control System
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of the
instrument panel.
The sensor monitors the sun’s solar radiation and uses
this information as
part of the automatic climate control
system when operating in the
AUTO mode.
Be careful not to put anything over the sensor. It cannot
compensate for changes in the amount of heat the
vehicle is absorbing from the sun when covered.
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor
is used for the outside air temperature readings
shown on the digital display for the automatic climate
control system. If
the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 20 mph (32 km/h) for
one and a half minutes.
0 The vehicle’s speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If your vehicle has been turned off for more than
three hours, the current outside temperature will be
shown when you start the vehicle. If it has been turned
off for less than three hours, the temperature will be
recalled from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located just left of the ignition switch.
The automatic climate control system uses this sensor
to receive information
so if you block or cover it, the
system will not function properly.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning Heating
On
very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot inside
air escape. Then keep your
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
RECIRCULATE setting is operating, airflow direction is
in the upper mode, and the temperature control knob (on
a manual climate control system) is turned all the way to
the blue area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum cooling is required.
When the air conditioning is on, you may sometimes
notice slight changes in your vehicle’s engine
performance and power. This is normal. The system is
designed to .help fuel economy while maintaining the
desired cooling level.
The
air conditioning removes moisture from the air, so you
may notice water dripping fi-om under your vehicle when
it is idling or after it has been turned
off. This is normal. The
heater works best
if you keep your windows closed.
Maximum heating will occur when airflow direction is
in the lower mode and the temperature control knob (on
a manual climate control system) is all the way
in the
red area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum heating is required.
The BI-LEVEL setting is designed for use on sunny days
when the
air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper body,
but your lower body may not
be warm enough. The
BI-LEVEL setting will direct cooler airflow to
your upper
body and warmer
air to the floor area.
If you have the optional engine coolant heater and use it
during cold weather
0°F (- 18 “C) or lower, your heating
system will provide heat more quickly because the
coolant is already warmed. See “Engine Coolant Heater”
in the Index.

Downloaded from www.Manualslib.com manuals search engine Rear Window Defogger
@ This button turns the rear defogger and heated
outside mirrors on. The light on the button will come
on when operating. The system automatically shuts
off
after approximately 10 minutes. If further defogging is
desired, press the button again.
The rear window defogger operates only when the
engine is running.
The rear window defogger uses a warming grid to
remove fog from the rear window.
Do not attach
anything like a temporary vehicle license or a decal
across the defogger grid on the rear window.
NOTICE:
Don’t use a razor blade or something sharp on
the inside
of the rear window. If you do, you
could cut or damage the warming grid, and
repairs wouldn’t be covered by your warranty.
Defogging and Defrosting
To rapidly defrost the windshield, the FRONT defrost
mode (electronic dual climate control system) or defrost
mode (manual control system) should be used and the
fan speed should be adjusted to the highest speed. With
the manual control system, turn the temperature control
knob all the way to the red area.
To keep the windshield clear and provide heated air to
the floor area of the vehicle, use the
DEFOG setting.
Your vehicle is equipped with side window defogger
vents located near the side rearview mirrors.
Ventilation System
Your vehicle’s flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the fan is running.
Ventilation Tips
0 Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

Downloaded from www.Manualslib.com manuals search engine Uniform Tire Quality Grading
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 -- A, B, C
The traction grades, from highest to lowest, are A, B, and
C, and they 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 braking (straight ahead) traction tests and does not
include cornering (turning) traction.
