lock CHEVROLET CORVETTE 1998 5.G Workshop Manual

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.

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.

Downloaded from www.Manualslib.com manuals search engine FRESH AIR: Press this button to provide fresh
air 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.
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.
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.
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.

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 When you enter a vehicle in cold weather, turn the
blower fan to the highest speed for a few moments
before driving
off. This helps clear the intake outlets
of snow and moisture, and reduces the chance of
fogging the inside of the windows.
Keep the area around the base of the center
instrument panel console and air path under the seats
clear of objects. This helps air circulate throughout
your vehicle.

Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking slud.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little.
This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.
Here’s how anti-lock works. Let’s say the road
is wet.
You’re driving safely. Suddenly an animal jumps out in
front
of you.
You slam on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
