air conditioning GMC CANYON 2005 Owner's Manual

Fan Knob
9
(Fan):The center knob on the control panel is used
to control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the knob is set on “0” (zero), some outside air will still
enter the vehicle and will be directed according to
the position of the mode knob.
Mode Knob
The right knob on the control panel is used to direct the
airow inside your vehicle. Turn the knob to select
one of the following modes:
H(Vent):Select this mode to direct air to the
instrument panel outlets.
\(Bi-Level):Select this mode to direct approximately
half of the air to the instrument panel outlets, and the
remaining air to the oor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):Select this mode to direct air to the oor
outlets. Enabling recirculation in heat mode may
cause interior window fogging under some conditions.
If this occurs, see “Defogging and Defrosting” following.
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 in the bi-level, vent and oor
(heat) modes. It should only be used while in bi-level
and vent modes. Recirculation is not available, and
the light will not come on, while in oor/defog or
defrost modes.
#(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
3-20

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.
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.

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

Radiator Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
SeeEngine Compartment Overview on page 5-12for
more information on location.
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.
5-28

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 4-56.
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.If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. Push down
the accelerator until the engine speed is about twice as
fast as normal idle speed for at least three minutes
while you are parked. If you still have the warning,turn
off the engine and get everyone out of the vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.
