air conditioning PONTIAC GRAND AM 2005 Owners Manual

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
To change the current mode, select one of the following:
HMAX:This mode is used for maximum cooling. It
will recirculate much of the air inside your vehicle.
It maximizes your air conditioner’s performance and your
vehicle’s fuel economy. The air-conditioning compressor
will run automatically in this mode when it is needed
to help dry the air in the vehicle.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs most of the
remaining air to the floor outlets with some air directed
at the side windows.
A(Floor):This mode directs most of the air to the
floor outlets with some air directed to the side windows.
The right knob can also be used to select defog or
defrost modes. Information on defogging and defrosting
can be found later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Temperature Control:Turn the center knob clockwise
or counterclockwise to manually increase or decrease
the temperature inside your vehicle.
When it’s cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-19.

A/C (Air Conditioning):Press this button to turn the
air-conditioning system on or off. When A/C is pressed,
an indicator light above the button will come on to let you
know that air conditioning is activated. The fan knob must
be set to a speed for the air conditioning to operate.
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:
1. Select the vent mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the recirculation mode.
5. Select the coolest temperature.
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.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 choose from to
clear fog or frost from your windshield. 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.
Turn the right knob clockwise or counterclockwise
to select defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield with most of the remaining air directed to the
floor outlets and some air directed at the side windows.
When you select this mode, the system turns off
recirculation automatically 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.
1FRONT (Defrost):This mode directs most of the air
to the windshield, with some air directed to the floor
outlets. In this mode, the system will automatically turn off
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. Do not drive the vehicle until all the windows
are clear.

Tire Size
The following illustration shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as the
first character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 60, as shown in item C of the
illustration, it would mean that the tire’s sidewall is
60 percent as high as it is wide.(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The letter
R means radial ply construction; the letter D means
diagonal or bias ply construction; and the letter B means
belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent
the load range and speed rating of the tire. The load
index represents the load carry capacity a tire is certified
to carry. The load index can range from 1 to 279. The
speed rating is the maximum speed a tire is certified
to carry a load. Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kiloPascal (kPa).
Accessory Weight:This means the combined weight
of optional accessories. Some examples of optional
accessories are, automatic transmission, power steering,
power brakes, power windows, power seats, and air
conditioning.
Aspect Ratio:The relationship of a tire’s height to its
width.

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, chafing, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect drum brake linings for wear or cracks.
Inspect other brake parts, including drums, wheel
cylinders, calipers, parking brake, etc.
(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, chafing, etc.
(c)Visually inspect hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
fittings 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.(d)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
(The airbag system does not need regular maintenance.)
(f)Lubricate all key lock cylinders, door hinges and
latches, hood hinges and latches and trunk lid hinges and
latches. More frequent lubrication may be required when
exposed to a corrosive environment. Applying silicone
grease on weatherstrips with a clean cloth will make them
last longer, seal better and not stick or squeak.
(g)Check system for interference or binding and for
damaged or missing parts. Replace parts as needed.
Replace any components that have high effort or
excessive wear. Do not lubricate accelerator or cruise
control cables.
