Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. You must fully apply the
regular brake before shifting from
P (Park) when the ignition key is in
ON/RUN. If you cannot shift out of
P (Park), ease pressure on the shift
lever, then push the shift lever all
the way into P (Park) as you
maintain brake application. Then
move the shift lever into another
gear. SeeShifting out of Park on
page 9‑22.
R (Reverse): Use this gear to
back up.
Notice: Shifting to R (Reverse)
while the vehicle is moving
forward could damage the
transmission. The repairs would
not be covered by the vehicle
warranty. Shift to R (Reverse) only
after the vehicle is stopped. To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission, see
If
the Vehicle Is Stuck on page 9‑10.
N (Neutral): In this position, the
engine does not connect with the
wheels. To restart the engine when
the vehicle is already moving, use
N (Neutral) only. Also, use
N (Neutral) when the vehicle is
being towed.
{WARNING
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D (Drive):
This position is for
normal driving. It provides the best
fuel economy. If you need more
power for passing, and you are:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
Notice: If the vehicle seems to
accelerate slowly or not shift
gears when you go faster, and
you continue to drive the vehicle
that way, you could damage the
transmission. Have the vehicle
serviced right away. You can
drive in L (Low) when you are
driving less than 56 km/h (35 mph)
and D (Drive) for higher speeds
until then.

9-28 Driving and Operating
Downshifting the transmission in
slippery road conditions could result
in skidding, see "Skidding" under
Loss of Control on page 9‑5.
L (Low):This position gives you
access to gear ranges. This
provides more engine braking but
lower fuel economy than D (Drive).
You can use it on very steep hills,
or in deep snow or mud. See the
following text on Manual Mode.Manual Mode
Electronic Range Select
(ERS) Mode
ERS mode allows you to choose the
top-gear limit of the transmission,
which can help control the vehicle's
speed while driving downhill or
towing a trailer. The vehicle has an
electronic shift position indicator
within the instrument cluster. When
using the ERS mode a number will
display next to the L, indicating the
current range that has been
selected. To use this feature:
1. Move the shift lever to L (Low).
2. Press the + (Plus) or
−(Minus)
button located on the left side of
the steering wheel, to increase
or decrease the gear range
available.
When you shift from D (Drive) to
L (Low), the transmission will shift to
a pre-determined lower gear range.
The highest gear available for this
pre-determined range is displayed
next to the L in the DIC. The
number displayed in the DIC is the
highest gear that the transmission
will be allowed to operate in. All
gears below that number are
available. For example, when
4 (Fourth) is shown next to the L,
1 (First) through 4 (Fourth) gears are
automatically shifted by the vehicle.
The transmission will not shift into
5 (Fifth) until the + (Plus) button is
used or you shift back into D (Drive).
While in L (Low), the transmission
will prevent shifting to a lower gear
range if the engine speed is
too high.

Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑20. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

9-30 Driving and Operating
Parking Brake
The parking brake is located to the
left of the brake pedal, near the
driver door.
To set the parking brake, hold the
brake pedal down, then push down
the parking brake pedal.
To release the parking brake, hold
the brake pedal down and push the
parking brake pedal. When you lift
your foot off the parking brake
pedal, the pedal will follow it to the
released position.A warning chime will sound and a
brake warning light located on the
instrument panel cluster will come
on, if the parking brake is set, the
ignition is on, and the vehicle speed
is greater than 8 km/h (5 mph).
Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
If you are towing a trailer and
parking on any hill, see Driving
Characteristics and Towing Tips on
page 9‑43.
Ride Control Systems
Traction Control
System (TCS)
The vehicle may have a Traction
Control System (TCS) that limits
wheel spin. This is especially useful
in slippery road conditions. The
system operates only if it senses
that one or both of the front wheels
are spinning or beginning to lose
traction. When this happens, the
system reduces engine power and
may also upshift the transmission
and apply the front brakes to limit
wheel spin.

Black plate (31,1)Chevrolet Impala Owner Manual - 2012
Driving and Operating 9-31
This light will flash when the TCS is
limiting wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. SeeCruise Control on
page 9‑34.
The TCS operates in all
transmission shift lever positions.
But the system can upshift the
transmission only as high as the
shift lever position chosen, so use
the lower gears only when
necessary. See Automatic
Transmission on page 9‑26.When the system is on, this warning
light comes on and stays on if there
is a problem.
A SERVICE TRACTION CONTROL
message also appears on the DIC.
When this warning light is on, the
system will not limit wheel spin.
Adjust your driving accordingly. See
Ride Control System Messages on
page 5‑33 for more information.
To limit wheel spin, especially in
slippery road conditions, TCS
should always be left on. But the
system can be turned off if needed.
Turn the system off if the vehicle
gets stuck in sand, mud, or snow
and rocking the vehicle is required.
See If the Vehicle Is Stuck on
page 9‑10 for more information.To turn the system on or off, press
the ESC OFF button located on the
instrument panel.
When the system is turned off, the
TRACTION CONTROL OFF
message appears on the DIC. If the
traction control system is limiting
wheel spin when the button is
pressed to turn the system off, the
TRACTION CONTROL OFF
message will appear on the DIC and
the system will turn off right away.
Press the ESC OFF button again to
turn the system back on. The
TRACTION CONTROL ON
message will appear in the DIC.
Adding non‐dealer accessories can
affect the vehicle performance. See
Accessories and Modifications on
page 10‑3for more information.

Driving and Operating 9-33
If the vehicle is in cruise control
when the system begins to assist
the driver maintain directional
control of the vehicle, the ESC/TCS
light will flash and the cruise control
will automatically disengage. When
road conditions allow you to use
cruise again, you may re-engage
the cruise control. SeeCruise
Control on page 9‑34.
The ESC OFF button is located on
the instrument panel.
The traction control system can be
turned off or back on by pressing
the ESC OFF button. To disable
both traction control and ESC, press
and hold the button briefly.
When the ESC system is turned off,
the TRACTION CONTROL OFF
message will appear, the
STABILITRAK OFF message will
appear, and the ESC OFF light will
be on solid to warn the driver that
both traction control and ESC are
disabled.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if your vehicle
is stuck in sand, mud, ice, or snow,
and you want to “rock”your vehicle
to attempt to free it. It may also be
necessary to turn off the system
when driving in extreme off-road
conditions where high wheel spin is
required. See If the Vehicle Is Stuck
on page 9‑10. ESC may also turn off automatically
if it determines that a problem exists
with the system. The SERVICE
STABILITRAK message and the
ESC/TCS light will be on solid to
warn the driver that ESC is disabled
and requires service. If the problem
does not clear after restarting the
vehicle, you should see your dealer
for service. See
Ride Control
System Messages on page 5‑33 for
more information.
Adding non‐dealer accessories can
affect your vehicle performance.

9-34 Driving and Operating
Cruise Control
With cruise control, you can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.If your vehicle has the Traction
Control System (TCS) and the
cruise control is on, TCS will begin
to limit wheel spin and the cruise
control automatically turns off . See
Traction Control System (TCS) on
page 9‑30. When road conditions
allow you to safely use it again, the
cruise control can be turned
back on.

(1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase vehicle speed. When you
take your foot off the pedal, the
vehicle will slow down to the cruise
speed you set earlier.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brakes are applied the
cruise control will turn off.
