air conditioning CHEVROLET COLORADO 2005 1.G Owners Manual

Mode Buttons
@
(Recirculation):If your vehicle has air
conditioning, you will have the recirculation feature. This
mode recirculates air inside the cabin, and prevents
outside air from coming in the vehicle. It can be used to
prevent outside odors from entering your vehicle and
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on or off. An
indicator light on the button will come on to let you know
the recirculation mode is activated.
Recirculation is available only in the bi-level and vent
modes. If you push the recirculation button in any other
mode, the light will not come on.
#(Air Conditioning):Your vehicle may have 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.
3-20

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.

DIC Warnings and Messages
Warning 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. More than one message may
appear at one time. They will appear one after the other.
The messages are displayed for three 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 message
and clear it from the display. Each message must
be acknowledged individually. Some messages cannot
be cleared from the display because they are more
urgent. These messages require action before they can
be removed from the DIC display. The following are
the possible messages that can be displayed and some
information about them.
AC (Air Conditioning) OFF
This message will be displayed when the engine coolant
temperature is too high and the air conditioning in
your vehicle needs to be turned off. SeeEngine
Overheating on page 5-28andClimate Control System
on page 3-19for more information. It will be displayed
along with the ENG HOT message.
ABS (Anti-Lock Brake System)
This message will be displayed if there is a problem
with your anti-lock brake system. Check your anti-lock
brake system as soon as possible and have your vehicle

Engine Overheating
You will nd a coolant temperature gage on your
vehicle’s instrument panel. SeeEngine Coolant
Temperature Gage on page 3-30.
Your air conditioning may stop working if your engine
is too hot. This is normal and helps cool the engine.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood.
Stay away from the engine if you see or hear
steam coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned. Stop
your engine if it overheats, and get out of
the vehicle until the engine is cool.Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
If No Steam Is Coming From Your
Engine
If you get an engine overheat warning but see or
hear no steam, the problem may not be too serious.
Sometimes the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” under
Towing a Trailer on page 4-54.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL
while stopped. If it is safe to do so, pull off the
road, shift to PARK (P) or NEUTRAL and let the
engine idle.
2. Turn off the air conditioning.
3. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.

between the plies and the tread. Cords may be made
from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped by
steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies are
laid at alternate angles less than 90 degrees to the
centerline of the tread.
Cold Ination Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat from
driving. SeeInation - Tire Pressure on page 5-58.
Curb Weight:This means the weight of a motor vehicle
with standard and optional equipment including the
maximum capacity of fuel, oil and coolant, but without

Maintenance Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chang, etc. Inspect
drum brake linings for wear or cracks. Inspect disc
brake pads for wear and rotors for surface condition.
Inspect other brake parts, including drums, wheel
cylinders, calipers, parking brake, etc. Check parking
brake adjustment.(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts or
signs of wear. Inspect power steering lines and hoses
for proper hook-up, binding, leaks, cracks, chang,
etc. Visually check constant velocity joints, rubber boots,
and axle seals for leaks.
(c)Visually inspect hoses and have them replaced if they
are cracked, swollen, or deteriorated. Inspect all pipes,
ttings, and clamps; replace with genuine GM parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
