2. Remove the old battery. Do notuse a metal object.
3. Insert the new battery, positive side facing down. Replace with a
CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
Your vehicle may have a remote
starting feature that allows you to
start the engine from outside the
vehicle. It may also start the
vehicle's heating or air conditioning
systems and rear window defogger.
When the remote start system is
active and the vehicle has an
automatic climate control system,
it will automatically regulate the
inside temperature. Normal
operation of these systems will
return after the ignition key is
turned to ON/RUN. Laws in some communities may
restrict the use of remote starters.
For example, some laws may
require a person using remote start
to have the vehicle in view when
doing so. Check local regulations for
any requirements on remote starting
of vehicles.
Do not use the remote start feature
if your vehicle is low on fuel. Your
vehicle may run out of fuel.
If your vehicle has the remote start
feature, the RKE transmitter
functions will have an increased
range of operation. However, the
range may be less while the vehicle
is running.
There are other conditions which
can affect the performance of the
transmitter. See
Remote Keyless
Entry (RKE) System on page 2‑2.
/(Remote Start): This button will
be on the RKE transmitter if you
have remote start.
To start the vehicle using the
remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release
Q, then
immediately press and hold
/
for two to four seconds or until
the vehicle's turn signal lamps
flash. The doors will lock.
When the vehicle starts, the
parking lamps turn on and
remain on while the engine is
running.
The remote start feature provides
two separate starts per ignition
cycle, each with 10 minutes of
engine running time, or one start
with a time extension. The first start
must expire or be canceled to get
two separate 10-minute starts.

For dual
zone, turn the thumbwheels up or
down to increase or decrease the
temperature on the driver or the
passenger side of the vehicle. For
single zone, turn the knob clockwise
or counterclockwise to increase or
decrease the temperature.
9(Fan Control): Turn clockwise
or counterclockwise to increase or
decrease the fan speed. Positioning
the knob between two modes can
select a combination of those
modes.
If the airflow seems low when the
fan is at the highest setting, the
passenger compartment air filter
may need to be replaced. There will
be some airflow noticeable from the
various outlets when driving, even
with the fan in the off position. For
more information, see Passenger
Compartment Air Filter on page 8‑6
and Scheduled Maintenance on
page 11‑2.

Black plate (3,1)Chevrolet Impala Owner Manual - 2011
Climate Controls 8-3
Air Delivery Mode Control:Turn
clockwise or counterclockwise to
change the direction of the airflow
inside the vehicle.
To change the current mode, select
one of the following:
H(Vent): Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
6(Floor): Air is directed to the
floor 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 floor outlets. When defog is
selected, the system turns off
recirculation and runs the air
conditioning compressor unless the
outside temperature is below
4°C (40°F).
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 floor 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
4°C (40°F).
#(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 flashing 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.
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.

Black plate (4,1)Chevrolet Impala Owner Manual - 2011
8-4 Climate Controls
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 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.
