Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can’t see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:
0 Your exhaust system sounds strange
Your vehicle gets rusty underneath.
0 Your vehicle was damaged in a collision.
0 Your vehicle was damaged when driving over
high points on the road or over road debris.
0 Repairs weren’t done correctly.
0 Your vehicle or exhaust system had

Running Your Engine While You’re
Parked (Automatic Transmission)
It’s better not to park with the engine running. But if you
ever Pn- to, hern ?re SOT? thingr tn 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.)

Downloaded from www.Manualslib.com manuals search engine Mode Buttons
These buttons control climate control ON/OFF, air
intake, front defrost, rear defrost and the air
conditioning operation.
FRONT Press the FRONT defrost button to
quickly remove fog or frost from the windshield. This
setting directs most of the airflow to the windshield and
a small amount toward
the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode.
If the system is in FRONT defrost when you shut the
engine
off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost.
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 NC: 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.
The air conditioning cools and dehumidifies
air coming
into the vehicle. It also operates in defrost to help
remove moisture from the vehicle. The air conditioning
does not operate at temperatures below approximately
35°F to 40°F (2°C to 4°C). If the system is operating in
the AUTO mode, turning the air conditioning off will
delete AUTO from the digital display and show current
mode and fan settings. The AUTO button must be
pressed to return to the automatic mode operation.
from the outside. The light on
this air intake button
will come on to show when it is operating. When in
the
AUTO mode, the system automatically selects FRESH
AIR instead of RECIRCULATE, as required, to control
the temperature
in the vehicle. By pressing FRESH AIR,
the system will lock into the fresh air mode . Any
adjustment to the air intake must then be made manually.
FRESH AIR should be used when trying to defrost or
defog windows to help reduce moisture inside the vehicle.
FRESH AIR: Press this button to provide fkesh air

Downloaded from www.Manualslib.com manuals search engine a RECIRCULATE: Press this button to limit the
amount of fresh air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. RECIRCULATE is helpful when you
are
trying to cool the air quickly or trying to limit odors
and dust from entering the vehicle. When in the AUTO
mode, the system automatically selects RECIRCULATE
to
cool the vehicle’s temperature. By pressing this
button, the system will lock into the recirculated air
mode. Any adjustment to the air intake must then be
made manually. The recirculated air mode is not
allowed in the front defrost or defog modes as fresh air
helps reduce moisture inside the vehicle.
Lfttr REAR WINDOW DEFOG: 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.
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 it is covered.

Downloaded from www.Manualslib.com manuals search engine 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:
0 The vehicle’s speed is above 20 mph (32 km/h)
for one and a half minutes.
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.
Air Conditioning
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 from under your vehicle when
it is idling or after it has been turned
off. This is normal.
3-11

Downloaded from www.Manualslib.com manuals search engine Heating
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 (- 18OC) or lower, your
heating system will provide heat more quickly because
the coolant is already warmed. See “Engine Coolant
Heater” in the Index.
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.
