2010 CHEVROLET IMPALA window

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,
floor, defog or defrost modes. If the button is selected
while in these modes, the indicator flashes three times.
Rear Window DefoggerThe 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 3-34.
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.

Compass CalibrationThe compass can be manually calibrated. Only calibrate
the compass in a magnetically clean and safe location,
such as an open parking lot, where driving the vehicle
in circles is not a danger. It is suggested to calibrate
away from tall buildings, utility wires, manhole covers,
or other industrial structures, if possible.
If CAL should ever appear in the DIC display, the
compass should be calibrated.
If the DIC display does not show a heading, for example,
N for North, or the heading does not change after making
turns, there may be a strong magnetic field interfering
with the compass. Such interference may be caused by a
magnetic CB or cell phone antenna mount, a magnetic
emergency light, magnetic note pad holder, or any other
magnetic item. Turn off the vehicle, move the magnetic
item, then turn on the vehicle and calibrate the compass.To calibrate the compass, use the following procedure:
Compass Calibration Procedure1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in
which the vehicle is located. See “Compass
Variance (Zone) Procedure” earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.
2. Press the vehicle information button until
PRESS
V
TO CALIBRATE COMPASS displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE IN
CIRCLES. Drive the vehicle in tight circles at less
than 5 mph (8 km/h) to complete the calibration.
The DIC will display CALIBRATION COMPLETE
for a few seconds when the calibration is complete.
The DIC display will then return to PRESS
V
TO
CALIBRATE COMPASS.

Cellular Phone UsageCellular phone usage may cause interference with
the vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
causes an increased level of static while listening to
the radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.Backglass AntennaThe AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Make sure that
the inside surface of the rear window is not scratched
and that the lines on the glass are not damaged. If the
inside surface is damaged, it could interfere with radio
reception. For proper radio reception, the antenna
connector needs to be properly attached to the post
on the glass.
If a cellular telephone antenna needs to be attached to
the glass, make sure that the grid lines for the AM-FM
antenna are not damaged. There is enough space
between the grid lines to attach a cellular telephone
antenna without interfering with radio reception.Notice:Using a razor blade or sharp object to clear
the inside rear window can damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by the vehicle warranty. Do not
clear the inside rear window with sharp objects.
Notice:Do not apply aftermarket glass tinting with
metallic film. The metallic film in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by the vehicle warranty.
XM™ Satellite Radio Antenna
SystemThe XM Satellite Radio antenna is located on the roof of
the vehicle. Keep the antenna clear of obstructions for
clear radio reception.
If the vehicle has a sunroof, the performance of the
XM system may be affected if the sunroof is open.

Blizzard ConditionsBeing stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use theRoadside Assistance Program on page 8-7.To
get help and keep everyone in the vehicle safe:•
Turn on theHazard Warning Flashers on page 4-3.
•
Tie a red cloth to an outside mirror.{
WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
•
Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
•
Check again from time to time to be sure
snow does not collect there.
WARNING: (Continued)
WARNING: (Continued)
•
Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
•
Fully open the air outlets on or under the
instrument panel.
•
Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting. See
Climate Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 3-31.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.
Run the engine for short periods only as needed to
keep warm, but be careful.
To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine off
and close the window most of the way to save heat.

If No Steam Is Coming From The
Engine CompartmentIf an engine overheat warning is displayed but no steam
can be seen or heard, the problem may not be too
serious. Sometimes the engine can get a little too hot
when the vehicle:•
Climbs a long hill on a hot day.
•
Stops after high-speed driving.
•
Idles for long periods in traffic.
•
Tows a trailer.
If the overheat warning is displayed with no sign of
steam:
1. Turn the air off.
2. Turn the heater on to the highest temperature and
to the highest fan speed. Open the windows as
necessary.3. In heavy traffic, let the engine idle in N (Neutral)
while stopped. If it is safe to do so, pull off the
road, shift to P (Park) or N (Neutral) and let
the engine idle.
If the temperature overheat gage is no longer in the
overheat zone or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive
the vehicle slow for about 10 minutes. Keep a safe
vehicle distance from the car in front of you. If the
warning does not come back on, continue to drive
normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
three minutes while parked. If the warning is still
displayed, turn off the engine until it cools down. Also,
see ‘‘Overheated Engine Protection Operating Mode’’
later in this section.

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.
Belt
:
A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead:
The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire
:
A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.Cold Tire Pressure
