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.

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.

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.
SeePower Mirrors on page 2‑15.
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.Air Vents
Use the thumbwheel located below
or to the side of the outlet, to
change the direction of the air flow.
Operation Tips
.Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into
the vehicle.
.Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
.Keep the path under the front
seats clear of objects to help
circulate the air inside the
vehicle more effectively.
.If the airflow seems low when
the fan is at the highest setting,
the passenger compartment air
filter, if equipped, may need to
replaced. For more information,
see Passenger Compartment Air
Filter on page 8‑6 and
Scheduled Maintenance on
page 11‑2.
.If fogging reoccurs while in vent
or bi-level modes with mild
temperature throughout the
vehicle, turn on the air
conditioner to reduce
windshield fogging.

9-4 Driving and Operating
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is
applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
Adding non‐dealer accessories can
affect vehicle performance. See
Accessories and Modifications on
page 10‑3.Steering
Power Steering
If power steering assist is lost
because the engine stops or the
system is not functioning, the
vehicle can be steered but it will
take more effort.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the road
surface, the angle at which the
curve is banked, and vehicle speed.
While in a curve, speed is the one
factor that can be controlled.
If there is a need to reduce speed,
do it before entering the curve, while
the front wheels are straight.
Try to adjust the speed so you can
drive through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until out of the curve, and
then accelerate gently into the
straightaway.
Steering in Emergencies
There are times when steering can
be more effective than braking. For
example, you come over a hill and
find a truck stopped in your lane,
or a car suddenly pulls out from
nowhere, or a child darts out from
between parked cars and stops right
in front of you. These problems can
be avoided by braking—if you can
stop in time. But sometimes you
cannot stop in time because there is
no room. That is the time for
evasive action —steering around
the problem.
The vehicle can perform very well in
emergencies like these. First apply
the brakes —but, unless the vehicle
has antilock brakes, not enough to
lock the wheels. See Braking on
page 9‑3. It is better to remove as
much speed as possible from a
Black plate (5,1)Chevrolet Impala Owner Manual - 2011
Driving and Operating 9-5
collision. Then steer around the
problem, to the left or right
depending on the space available.
An emergency like this requires
close attention and a quick decision.
If holding the steering wheel at the
recommended 9 and 3 o'clock
positions, it can be turned a full
180 degrees very quickly without
removing either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once
you have avoided the object.The fact that such emergency
situations are always possible is a
good reason to practice defensive
driving at all times and wear safety
belts properly.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving.
If the level of the shoulder is only
slightly below the pavement,
recovery should be fairly easy. Ease
off the accelerator and then, if there
is nothing in the way, steer so thatthe vehicle straddles the edge of the
pavement. Turn the steering wheel
8 to 13 cm (3 to 5 inches), about
one-eighth turn, until the right front
tire contacts the pavement edge.
Then turn the steering wheel to go
straight down the roadway.
Loss of Control
Let us review what driving experts
say about what happens when the
three control systems
—brakes,
steering, and acceleration —do not
have enough friction where the tires
meet the road to do what the driver
has asked.
In any emergency, do not give up.
Keep trying to steer and constantly
seek an escape route or area of
less danger.
Black plate (6,1)Chevrolet Impala Owner Manual - 2011
9-6 Driving and Operating
Skidding
In a skid, a driver can lose control of
the vehicle. Defensive drivers avoid
most skids by taking reasonable
care suited to existing conditions,
and by not overdriving those
conditions. But skids are always
possible.
The three types of skids correspond
to the vehicle's three control
systems. In the braking skid, the
wheels are not rolling. In the
steering or cornering skid, too much
speed or steering in a curve causes
tires to slip and lose cornering force.
And in the acceleration skid, too
much throttle causes the driving
wheels to spin.
If the vehicle starts to slide, ease
your foot off the accelerator pedal
and quickly steer the way you want
the vehicle to go. If you start
steering quickly enough, the vehicle
may straighten out. Always be ready
for a second skid if it occurs.Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
slow down and adjust your driving to
these conditions. It is important to
slow down on slippery surfaces
because stopping distance will be
longer and vehicle control more
limited.
While driving on a surface with
reduced traction, try to avoid
sudden steering, acceleration,
or braking, including reducing
vehicle speed by shifting to a lower
gear. Any sudden changes could
cause the tires to slide. You may not
realize the surface is slippery until
the vehicle is skidding. Learn to
recognize warning clues
—such as
enough water, ice, or packed snow
on the road to make a mirrored
surface —and slow down when you
have any doubt. If the vehicle has the Antilock Brake
System (ABS), remember: It helps
avoid only the braking skid. If the
vehicle does not have ABS, then in
a braking skid, where the wheels
are no longer rolling, release
enough pressure on the brakes to
get the wheels rolling again. This
restores steering control. Push the
brake pedal down steadily when you
have to stop suddenly. As long as
the wheels are rolling, you will have
steering control.

Driving and Operating 9-9
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in
your own lane.
.Top of hills: Be
alert—something could
be in your lane (stalled car,
accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or
grip. Wet ice can occur at about
0°C (32°F) when freezing rain
begins to fall, resulting in even less
traction. Avoid driving on wet ice or
in freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction. Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The
Antilock Brake System (ABS)
on page 9‑27 improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control on
slippery surfaces.
