2005 CHEVROLET CORVETTE climate control

Manual Operation
Driver Power/Temperature:Press the driver
temperature knob on the driver side of the climate
control panel to turn the climate control system off. This
is the only setting that completely shuts off the fan.
The digital display will show only the outside
temperature. You can still adjust the driver and the
passenger set temperature and the air intake mode
when the climate control is off.
Passenger Power/Temperature:Press the passenger
temperature knob on the passenger side of the
climate control panel to turn the passenger’s climate
control system on or off. Turn the knob to increase
or decrease the temperature for the passenger. If the
passenger’s climate control system is off, the driver’s
temperature knob will control the temperature for
the entire vehicle.
N(MODE):Press this 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.To change the current mode, select one of the following:
H(Vent):This mode directs most of the air to the
instrument panel outlets, with a very small amount of air
directed to the oor outlets.
%(Bi-Level):This mode directs about half of the air
to the instrument panel outlets, and directs the
remaining air to the oor outlets. Cooler air is directed
to the upper outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the side
window defogger outlets and some air directed toward
the windshield.
The MODE button can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
x9w(Fan):Press the button with the fan symbol
to manually increase or decrease the fan speed.
Keep pressing the up or down arrow on this switch until
the desired fan speed appears on the display.
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
ows into the vehicle, press the up arrow on the
fan switch. To decrease the fan speed and airow,
press the down arrow. The AUTO button must be
pressed to return to the automatic fan control.

If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate control
system is in recirculation mode an indicator light
will come on. This mode prevents outside air from
entering your vehicle. It can be used to prevent outside
air and odors from entering your vehicle and to help
cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.
^(Air Conditioning Off):Press this button to turn
the air conditioning compressor off. Press AUTO
to return to automatic operation. When in AUTO, the air
conditioning compressor will come on automatically,
as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days press the AUTO
button and adjust the temperature to a cool, comfortable
setting. To achieve maximum cool down, do the
following:
1. Select the vent mode.
2. Select recirculation mode.
3. Select the A/C on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.

Sensors
The solar sensor on your vehicle monitors the solar
radiation and uses the information to maintain the
selected temperature when operating in AUTO mode by
initiating needed adjustments to the temperature, the
fan speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing
the sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on
the top of the instrument panel near the windshield
or the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 10 mph (16 km/h)
ve minutes.
The vehicle’s speed is above 32 mph (52 km/h) for
two and a half minutes.
These delays prevent false readings. If the temperature
goes down, the 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.There is also an inside temperature sensor located to
the 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.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
and moisture condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use defrost to remove fog or frost from
the windshield more quickly. To prevent fogging on
the inside of the windows in modes other than
oor/defog and defrost, make sure the air conditioning
compressor is on and recirculation mode is off.
Press the mode button until the defog mode appears on
the display.
-(Floor/Defog):This mode directs the air equally
between the windshield and the oor outlets with a small
amount to the side window outlets. When you select
this mode, the system turns off recirculation and runs the
air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the defog mode.

Outlet Adjustment
Use the tab located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter removes certain
odor and particles from the air including pollen and dust
particles. Reductions in airow, which may occur
more often in dusty areas, indicate that the lter may
need to be replaced. SeeScheduled Maintenance
on page 6-4for information on how often to replace the
lter.Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the old
lter with a new one.
The passenger compartment air lter is located on the
passenger side of the engine compartment near the
battery. SeeEngine Compartment Overview on
page 5-12.
To check or replace the air lter, do the following:
1. Disengage the passenger compartment air lter
housing cover retainer clips (1).
2. Remove the passenger compartment air lter
housing cover.

acknowledge that you have read the message and to
remove it from the display, press the RESET button. The
message will reappear every ve minutes until this
condition changes.
If the Driver Information Center (DIC) displays the
REDUCED ENGINE POWER message and the CHECK
ENGINE light comes on, a noticeable reduction in the
vehicle’s performance may occur. If the REDUCED
ENGINE POWER message is displayed but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time
the vehicle is driven.
The vehicle may be driven at a reduced speed while the
REDUCED ENGINE POWER message is displayed,
but acceleration and speed may be reduced. Anytime
the CHECK ENGINE light stays on, the vehicle
should be taken to your GM dealer as soon as possible
for diagnosis and repair.
Also, seeMalfunction Indicator Lamp on page 3-42.If
the REDUCED ENGINE POWER message is displayed
in combination with the COOLANT OVER
TEMPERATURE message, seeEngine Overheating on
page 5-24.SERVICE ACTIVE HANDLING SYSTEM:If the
SERVICE ACTIVE HANDLING SYSTEM message is
displayed, there is a problem with your Active Handling
System and your vehicle needs service. See your
GM dealer. The instrument cluster light will also be on
and a chime will sound. When this message is
displayed, the system is not working. Adjust your driving
accordingly. SeeActive Handling System on page 4-10
for more information.
SERVICE AIR CONDITIONING:This message displays
when the electronic sensors that control the air
conditioning and heating systems are no longer working.
Have the climate control system serviced by your
GM dealer if you notice a drop in heating and air
conditioning efficiency.
SERVICE ANTILOCK BRAKES:If the SERVICE
ANTILOCK BRAKES message is displayed when you
are driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the message stays on, or comes back
on again while you are driving, your vehicle is in need
of service. See your GM dealer. If the anti-lock
brake system warning light is on and the regular brake
system warning light is not on, you still have brakes,
but do not have anti-lock brakes. If the regular
brake system light is also on, you do not have anti-lock
brakes and there is a problem with your brakes. See
Anti-Lock Brake System Warning Light on page 3-39
andBrake System Warning Light on page 3-38.

DIC Vehicle Personalization
Many features on your vehicle can be personalized.
This means that the operation of these features can be
set to operate differently depending on who is driving
the vehicle. See “Personal Options” later in this section
for the features that you can personalize.
The personalization settings for other features are
automatically updated and saved as the driver adjusts
them. These include the following settings and presets:
The radio presets, tone, volume, fade,
balance, equalization (EQ) settings and source
(radio or CD)
The last climate control setting
The Head-Up Display (HUD) position and dimming
level, if equipped
The instrument panel cluster dimming level and last
selected DIC display
Separate personalization settings are saved for two
different drivers. One of the keyless access transmitters
is assigned to driver 1. The other is assigned to
driver 2. The back of the keyless access transmitters
are labelled 1 or 2 to correspond to each driver.The current driver’s preferences are recalled when one
of the following occurs:
The lock or unlock button on the keyless access
transmitter, labelled 1 or 2, is pressed.
The appropriate memory button, 1 or 2, located on
the driver’s door is pressed. SeeMemory on
page 2-68for more information.
A valid keyless access transmitter is detected upon
opening the driver’s door.
If more than one valid keyless access transmitter is
detected upon opening the driver’s door, the driver
preferences for the lowest driver number will be recalled.
If a keyless access transmitter that is not labelled 1 or 2
is used, the personalization system will not recognize
the transmitter. The Driver Information Center (DIC) will
not display a current driver number and the features
that are normally programmed through the DIC will be
set to the default states. Also, if the OPTION button
is pressed, the DIC does not display the menus used to
set personalizations, but instead displays OPTIONS
UNAVAILABLE for a few seconds.

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 specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) 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 signicantly 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 specied 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.
