Repeat this until help arrives
but only when you feel really
uncomfortable from the cold.
Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If the vehicle has a traction
system, it can often help to free
a stuck vehicle. Refer to the
vehicle's traction system in theIndex. If stuck too severely for the
traction system to free the vehicle,
turn the traction system off and use
the rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph) as
shown on the speedometer.
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑58.
Rocking the Vehicle to
Get it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction or
stability system. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears.
Release the accelerator pedal while
shifting, and press lightly on the
accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. If the vehicle
does need to be towed out, see
Towing the Vehicle on page 10‑74.

Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
In an emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location. 3. Come to a complete stop, shift
to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑29
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from left to right while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle
needs service.
B (ACC/ACCESSORY): This is the
position in which you can operate
the radio and windshield wipers
while the engine is off. To use
ACC/ACCESSORY, turn the key
clockwise. C (ON/RUN):
This position can
be used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. The switch
stays in this position when the
engine is running.
If you leave the key in the ACC/
ACCESSORY or ON/RUN position
with the engine off, the battery could
be drained. You may not be able to
start the vehicle if the battery is
allowed to drain for an extended
period of time.
D (START): This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving.
A warning chime will sound and the
Driver Information Center (DIC) will
display DRIVER DOOR OPEN
when the driver door is opened, the
ignition is in ACC/ACCESSORY or
LOCK/OFF, and the key is in the
ignition. See Door Ajar Messages

driving less than 35 mph (55 km/h)
and D (Drive) for higher speeds
until then.
3 (Third):This position is also used
for normal driving. However, it
reduces vehicle speed more than
D (Drive) without using the brakes.
You might choose 3 (Third) instead
of D (Drive) when driving on hilly,
winding roads, when towing a trailer,
so there is less shifting between
gears and when going down a
steep hill.
2 (Second): This position reduces
vehicle speed even more than
3 (Third) without using the brakes.
You can use 2 (Second) on hills.
It can help control vehicle speed as
you go down steep mountain roads.
You would also want to use the
brakes off and on.
Notice: Driving in 2 (Second) for
more than 25 miles (40 km) or at
speeds over 55 mph (90 km/h)
may damage the transmission. Also, shifting into 2 (Second) at
speeds above 65 mph (105 km/h)
can cause damage. Drive in
3 (Third) or D (Drive) instead of
2 (Second).
1 (First):
This position reduces
vehicle speed even more than
2 (Second) without using the brakes.
You can use it on very steep hills,
or in deep snow or mud. If the shift
lever is in 1 (First) while the vehicle
is moving forward, the transmission
will not shift into first gear until the
vehicle is going slowly enough.
Notice: Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.Brakes
Antilock Brake
System (ABS)
The vehicle might have the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
If the vehicle has ABS, this warning
light comes on briefly when the
vehicle is started.
The warning light is on the
instrument panel cluster. See
Antilock Brake System (ABS)

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 9‑41.
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.
This light will flash when the TCS is
limiting wheel spin.

Black plate (30,1)Chevrolet Impala Owner Manual - 2011
9-30 Driving and Operating
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 9‑32.
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 9‑25.
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 5‑32 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 9‑11 for more information.
To turn the system on or off, press
the Traction Control button located
on the instrument panel.
When the system is turned off, the
traction control warning light comes
on and TRACTION CONTROL OFF
appears on the DIC. If the traction
control system is limiting wheel spin
when the button is pressed to turn
the system off, the warning light
comes on and the system will turn
off right away.
Press the Traction Control button
again to turn the system back on.
The Traction Control warning light
should go off.

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 9‑11.
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 5‑32 for
more information.
Adding non‐dealer accessories can
affect your vehicle's performance.
See Accessories and Modifications
on page 10‑3 for more information.
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
