2009 CHEVROLET IMPALA light

Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on and off.
Mirror Reading Lamps
The vehicle has reading lamps on the rearview mirror.
Push the button to turn the reading lamps on and off.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not
be spinning fast enough at idle to produce all the
power that is needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams,
fog lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 3-49.

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/retailer for additional information on
the power accessory plugs.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would
not be covered by the vehicle 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/retailer 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 the 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
The vehicle may have an ashtray and a cigarette lighter.
The ashtray and cigarette lighter may be located in the
console, if the vehicle has one, otherwise, they may be
located in the center armrest of the front seat.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage the 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 is ready, it will pop back out by itself.

6(Floor):Air is directed to the oor outlets, with
some of the air directed to the windshield and side
window outlets. In this mode, the system automatically
selects outside air.
-(Defog):This mode clears the windshield of fog or
moisture. Air is directed 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 clears the windshield of fog or
frost more quickly. Air is directed to the windshield with
some air to the side window vents and the oor vents.
When defrost is selected, the system automatically
forces 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).
#(Air Conditioning):Press to turn the air
conditioning system on or off. An indicator light
comes on to show that it is on. The air conditioning
can be selected in any mode as long as the fan is
on and the outside temperature is above freezing.
A ashing indicator light indicates that the air
conditioning compressor is currently not available.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the 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
Hmode.
2. Press the
#button.
3. Select the coolest temperature for both zones.
4. Select the highest
9speed.
5. When the coolest temperature is selected in the
A/C mode, the system automatically goes into the
recirculation mode to improve cooling.
3-21

Using these settings together for long periods of time
may cause the air inside the vehicle to become too dry.
To prevent this from happening, after the air inside
the vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so a small amount of water may drip under
the vehicle while idling or after turning off the engine.
This is normal.
:(Outside Air):Press to turn on outside air.
An indicator light comes on to show that it is on.
Outside air will circulate throughout the vehicle.
?(Recirculation):Press to turn on the recirculation
mode. An indicator light comes on to show that it is on.
This mode helps to quickly heat or cool the air inside the
vehicle once the temperature inside the vehicle is equal
to or better than the outside temperature. It can be used
to prevent outside air and odors from entering the vehicle.
The recirculation mode is not available in outside air,
oor, defog or defrost modes. If the button is selected
while in these modes, the indicator ashes three times.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):The rear window
defogger turns off automatically after it has been
activated for 10 minutes. It can be turned off manually,
by pressing the button again or by turning the ignition
to the LOCK/OFF position. The rear window defogger
can be turned on again for additional window clearing.
The length of defogger operation will increase if the
vehicle is being driven.
For vehicles with heated outside rearview mirrors, the
mirrors heat to help clear fog or frost from the surface
of the mirror when the rear window defog button is
pressed. SeeOutside Power Mirrors on page 2-32.
Do not drive the vehicle until all the windows are clear.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would
not be covered by the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or anything
similar to the defogger grid.

Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or
is a problem with one of the vehicle’s functions.
Some warning lights come on briey when the
engine is started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains
what to do. Follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.

the airbag sensor, the pretensioners, the airbag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-57.
The airbag readiness light
ashes for a few seconds
when the engine is started.
If the light does not come
on then, have it xed
immediately.{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have
the vehicle serviced right away.
If there is a problem with the airbag system, an airbag
