2003 CHEVROLET MONTE CARLO climate control

Defogging and Defrosting
Fog on the inside of your 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
fog or moisture from the windows and warm the
passengers. Use the defrost mode to quickly remove
fog or frost from the windshield.
Turn the right knob clockwise or counterclockwise to
select one of the following modes:
/(Defog):This mode directs half of the air to the
windshield and side window vents and half to the ¯oor
vents. In this mode, the system will automatically
force outside air into your vehicle. The recirculation
mode cannot be selected while in the defog mode. The
air conditioning compressor will run automatically in
this setting, unless the outside temperature is below
40ÉF (4ÉC).
Do not drive the vehicle until all the windows are clear.
0(Defrost):This mode directs most of the air to the
windshield and the side window vents, with only a
little air directed to the ¯oor vents. In this mode, the
system will automatically force outside air into your
vehicle. There is a 5 minute timer linked to this function.
The recirculation mode cannot be selected while in
the defrost mode. The air conditioning compressor will
run automatically in this setting, unless the outside
temperature is below 40ÉF (4ÉC).
Do not drive the vehicle until all the windows are clear.
To circulate outside air and clear the windshield
quickly and bring outside air into your vehicle, do the
following:
1. Select defrost mode.
2. Select the temperature.
3. Select the highest fan speed.

Ventilation Tips
·
Clear away any ice, snow or leaves from the air
inlets on the hood that may block the ¯ow of air
into your vehicle. This will help to remove fog
or frost from the windows it will also improve
heating.
·Select the ¯oor mode and set the fan at the highest
speed when ®rst starting your vehicle to help clear
the air intake ducts of moisture or snow. This
will also help to remove fog from the windows.
·Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air ®lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger's side of the vehicle, underneath
the air inlet grille.
The ®lter traps most of the pollen from air entering the
Climate Control System. Like your engine's air
cleaner/®lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
®lter, see
Scheduled Maintenance on page 6-5.

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, 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
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 speci®ed 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 signi®cantly 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 speci®ed 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.
