climate control CHEVROLET CORVETTE 2007 6.G User Guide

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.
1(Defrost):Pressing this button directs most
of the air to the windshield, with a small amount
directed to the 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. In this mode, the
system will automatically turn off the recirculation
and run the air-conditioning compressor, unless
the outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode. Pressing this button again will return
the system to the last operating mode.
For severe ice conditions, turn the driver’s
temperature knob to 90°F (32°C) while in
defrost mode.
Do not drive the vehicle until all the windows
are clear.

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 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 433for 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 330.

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 dealer if you notice
a drop in heating and air conditioning efficiency.
SERVICE ANTILOCK BRAKES
If this message displays while 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 dealer. If the anti-lock brake system (ABS)
warning light is on and the regular brake system
warning light is not on, you still have brakes, but do
not have ABS. If the regular brake system warning
light is also on, you do not have ABS and there is a
problem with the brakes. SeeAnti-Lock Brake
System Warning Light on page 197andBrake
System Warning Light on page 196.
If this message is displayed, the Traction Control
System (TCS) and the Active Handling System
will also be disabled. The DIC will scroll three
messages: SERVICE ANTILOCK BRAKES,
SERVICE TRACTION SYSTEM, and SERVICEACTIVE HANDLING, and the instrument panel
cluster lights will come on along with a chime.
When the service message is displayed, the
computer controlled systems will not assist the
driver. Have the system repaired by your dealer as
soon as possible. Adjust your driving accordingly.
To acknowledge these messages, press the
RESET button.SERVICE CHARGING SYSTEM
If this message displays while you are driving,
there may be a problem with the electrical charging
system. It could mean that there is a loose or
broken drive belt or that there is another electrical
problem. Have your vehicle checked right away
by your dealer. Driving while this message is
on could drain the battery.
If you must drive a short distance with the
message on, be certain to turn off the vehicle’s
accessories, such as the radio and air conditioner.
Multiple chimes sound when this message is
displayed.
To acknowledge the message, press the RESET
button. The message reappears every 10 minutes
until this condition changes.

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 your vehicle has this feature
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
Seat, Mirrors and Steering Wheel on
page 10for 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.

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.
Temperature – A, B, C
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance to
the generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specied indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
Warning:The temperature grade for this tire is
established for a tire that is properly inated and
not overloaded. Excessive speed, underination,
or excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
