climate control CHEVROLET IMPALA 2007 9.G User Guide

Accessory Power Outlet(s)
Your vehicle has three 12-volt outlets which can be
used to plug in electrical equipment such as a
cellular telephone, a compact disc player, etc.
On vehicles with a center console, one outlet is
located at the rear of the console in the bottom of
the bin and two outlets are located at the front
of the console bin under the instrument panel.
Lift the cover to access the outlet. Close the cover
when not using the outlet.
On vehicles without a center console, two are
located under the climate controls and another
outlet for the rear seat passengers is at the rear
of the center front seat. Remove the rubber
cover to access the outlets. When not using
the outlet, make sure the cover is on it.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.Certain accessory plugs may not be compatible to
the accessory power outlet and could result in
blown vehicle and adapter fuses. If you experience
a problem, see your dealer for additional
information on the power accessory plugs.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should.
The repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer/retailer before adding
electrical equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment. Check with your dealer
before adding electrical equipment, and never use
anything that exceeds the maximum amperage
rating of 20 amps.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.

Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and a cigarette
lighter. The ashtray and cigarette lighter may
be located in the console, if your vehicle has one,
otherwise, they may be located in the center
armrest of the front seat.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
Notice:Holding a cigarette lighter in while
it is heating does not let the lighter back away
from the heating element when it is hot.
Damage from overheating can occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in while it
is heating.
To use the lighter, just push it in all the way and
let go. When it’s ready, it will pop back out by itself.
Climate Controls
Climate Control System
This vehicle may have a dual or single climate
control system. With this system you can control
the heating, cooling, defrost, defog and
ventilation for the vehicle. If this vehicle has
heated seats, seeHeated Seats on page 10.
Dual Zone with Optional Heated Seat Controls
168

:(Outside Air):Press this button to turn on
outside air. When this mode is on, outside air
will circulate throughout your vehicle. When the
button is pressed, an indicator light will come on to
show that it is on.
?(Recirculation):Press this button to turn
on the recirculation mode. When the button
is pressed, an indicator light will come on to show
that it is on.
This mode keeps outside air from entering the
vehicle. It can be used to prevent outside air and
odors from entering your vehicle. Recirculation
may also help heat or cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is equal to or better than the outside
temperature. The recirculation mode cannot
be used with outside air, oor, defrost, or
defogging modes.
Temperature Control:Turn the thumbwheels up
or down to increase or decrease the temperature
on the driver’s side or the passenger side of
the vehicle for the dual zone system. Turn the
center knob clockwise or counterclockwise
to increase or decrease the temperature for the
single zone system.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. When
A/C is pressed, an indicator light will come on to
let you know that the air conditioning is on.
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, do the
following:
1. Select the vent mode.
2. Select A/C.
3. Select the coolest temperature for both zones.
4. Select the highest fan speeds.
5. When the coolest temperature is selected in
the A/C mode, the system will automatically
go into the recirculation mode to improve
cooling. Press the Outside Air or Recirculation
button to turn off the automatic recirculation.
This feature will stay off until the climate
control system is powered on again or the
vehicle has been turned off and on again.

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 inside of 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 the 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. 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.Do not drive the vehicle until all the windows
are clear.
Turn the right knob clockwise to select the defog
or defrost mode.
-(Defog):This mode directs air equally to the
windshield and the oor outlets. When defog
is selected, the system turns off recirculation and
runs the air conditioning compressor unless
the outside temperature is below 40°F (4°C).
0(Defrost):This mode directs most of the air to
the windshield with some air to the side window
vents and the oor vents. When defrost is selected,
the system will automatically force outside air into
the vehicle. The air conditioning compressor will run
automatically in this setting, unless the outside
temperature is below 40°F (4°C).

Passenger Compartment Air Filter
This vehicle has 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, under 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 ensure system performance. For
information on how often to change the passenger
compartment air lter, seeScheduled Maintenance
on page 408.
To change the passenger compartment air lter,
use the following steps:
1. Turn off the ignition when the windshield
wipers are in the up position.
2. Raise the vehicle hood.
3. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway
to center.4. Remove the air inlet grille retainers.
5. Lift the air inlet grille and disconnect the
washer hose at the quick-connect.
6. Remove the air inlet grille.
7. Remove the water deector plate.
8. Remove the old passenger compartment
air lter.
9. Reverse the steps to install the new air lter.
For best climate control system performance,
be sure to re-install the air lter.
For the type of lter to use, seeNormal
Maintenance Replacement Parts on page 419.

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.
