2007 CHEVROLET COLORADO climate control

Recirculation is only available in the bi-level and
vent modes. It should only be used while in bi-level
and vent modes. Recirculation is not available,
and the light will not come on or ash while in heat,
oor, oor/defog, or defrost modes.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. An indicator
light on the button will come on to let you know
the air conditioning is activated. When the system
is on, this setting cools and dehumidies the
air entering your vehicle.
The air conditioning will not function if the fan is
turned off.
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.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.Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (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 and side windows. Use the defog
mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly. For best results, clear all snow and
ice from the windshield before defrosting.
179

Turn the mode knob on the climate control panel
clockwise to select the defog or defrost modes.
/(Floor/Defog):This mode directs the air to the
windshield, the side window outlets, and to the oor
outlets. When you select this mode, the system
runs the air conditioning compressor unless the
outside temperature is near freezing or below.
Recirculation is not available in this mode.
0(Defrost):This mode directs most of the
air to the windshield, and the side window outlets.
When you select this mode, the system runs
the air conditioning compressor unless the
outside temperature is near, or below freezing.
Recirculation is not available in this mode.
Do not drive the vehicle until all the windows
are clear.
Outlet Adjustment
Use the thumbwheel on the outlets to change the
direction of the air ow.
Lift up or push down on the thumbwheel located
in the center of the outlet to direct the air up
or down, or slide the thumbwheel to the left or
right to direct the airow from side-to-side.
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 path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 88for more on this,
including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light
on page 185.
Battery Warning Light
This light will come
on briey when you
start the vehicle,
as a check to show
you it is working;
then it should go out.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical
charging system. Have it checked right away.
Driving while this light is on could drain your
battery and result in a vehicle that may stall.
SeeDIC Warnings and Messages on page 202
for more information.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and climate control system.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may
appear one after another. The messages are
displayed for several seconds each.
Some messages may not require immediate
action, but you should press and release the
trip odometer reset stem to acknowledge that you
received the messages and to clear them from
the display. Each message must be acknowledged
individually.
Some messages cannot be cleared from the
DIC display because they are more urgent.
These messages require action before they
can be cleared. You should take any messages
that appear on the display seriously and remember
that clearing the messages only makes the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
AC (Air Conditioning) OFF
This message displays when the engine coolant
temperature is too high and the air conditioning
in your vehicle needs to be turned off. SeeEngine
Overheating on page 348andClimate Control
System on page 177for more information.
This message displays along with the ENG HOT
message.
ABS (Anti-Lock Brake System) FAULT
This message displays if there is a problem
with the Anti-Lock Brake System (ABS). Check
the ABS as soon as possible and have your
vehicle serviced by your dealer. SeeBrakes on
page 357andAnti-Lock Brake System Warning
Light on page 190for more information. Press
and release the reset stem to acknowledge
the message and clear it from the display.
BRAKES
This message displays if there is a problem with
the brakes. Check the brakes as soon as possible
and have your vehicle serviced by your dealer.

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 (NHTSA),
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
(UTQG) 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.
