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
on page 5‑29 for more information.

When the Low Fuel warning
lamp is on and the FUEL LEVEL
LOW message is displayed in
the Driver Information Center
(DIC), the Computer‐Controlled
Cranking System is disabled to
prevent possible vehicle
component damage. When this
happens, hold the ignition switch
in the START position to
continue engine cranking.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down. 2. If the engine does not start after
5‐10 seconds, especially in very
cold weather (below −18°C or
0°F), it could be flooded with too
much gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for
up to a maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, let go of
the key and accelerator. If the
vehicle starts briefly but then
stops again, repeat these steps. This clears the extra gasoline
from the engine. Do not race the
engine immediately after starting
it. Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the engine operates.
Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.

on the console between the seats.
There is a display, located on the
instrument panel cluster, that will
indicate the gear the vehicle is in.
Maximum engine speed is limited on
automatic transmission vehicles
while in P (Park) or N (Neutral) to
protect driveline components from
improper operation.
There are several different positions
for the shift lever. P (Park):
This position locks the
front wheels. It is the best position
to use when the engine is started
because the vehicle cannot
move easily.

Electronic Stability
Control (ESC)
Your vehicle may have an Electronic
Stability Control (ESC) system
which combines antilock brake,
traction, and stability control
systems and helps the driver
maintain directional control of the
vehicle in most driving conditions.
When you first start your vehicle
and begin to drive away, the system
performs several diagnostic checks
to ensure there are no problems.
You may hear or feel the system
working. This is normal and does
not mean there is a problem with
your vehicle. The system should
initialize before the vehicle reaches
32 km/h (20 mph). If the system fails to turn on or
activate, the ESC/TCS light will be
on solid, and the SERVICE
STABILITRAK message will be
displayed.
For more information, see
Ride
Control System Messages on
page 5‑32.
This light will flash on the instrument
panel cluster when the ESC system
is both on and activated.
You may also feel or hear the
system working; this is normal.
When the light is on solid and the
SERVICE STABILITRAK message
is displayed, the system will not
assist the driver in maintaining
directional control of the vehicle. Adjust your driving accordingly. See
Ride Control System Messages on
page 5‑32.
The Electronic Stability
Control (ESC) system is
automatically enabled whenever you
start your vehicle. To assist the
driver with vehicle directional
control, especially in slippery road
conditions, you should always leave
the system on. But, you can turn
ESC off if you ever need to.
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

operating range, the engine could
be damaged. You should drain
out the excess oil or limit your
driving of the vehicle and seek a
service professional to remove
the excess amount of oil.
SeeEngine Compartment Overview
on page 10‑6 for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade:
Specification
Use and ask for engine oils with the
dexos™ certification mark. Oils
meeting the requirements of your
vehicle should have the dexos™
certification mark on the container. This certification mark indicates that
the oil has been approved to the
dexos™
specification.
Your vehicle was filled at the factory
with dexos™ approved engine oil.
Notice: Use only engine oil that is
approved to the dexos™
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine oils
approved to the dexos™
specification will show the
dexos™ symbol on the container.
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty. If you are
unsure whether your oil is
approved to the dexos™
specification, ask your service
provider. Use of Substitute Engine Oils if
dexos™
is unavailable: In the event
that dexos™ approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil
displaying the API Starburst symbol
and of SAE 5W-30 viscosity grade.
Use of oils that do not meet the
dexos™ specification, however, may
result in reduced performance under
certain circumstances.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity oils such as
SAE 10W‐30, 10W‐40, or 20W-50.

Black plate (10,1)Chevrolet Impala Owner Manual - 2011
10-10 Vehicle Care
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below−29°C
(−20°F), an SAE 0W-30 oil should be used. An oil of this viscosity
grade will provide easier cold
starting for the engine at extremely
low temperatures. When selecting
an oil of the appropriate viscosity
grade, be sure to always select
an oil that meets the required
specification, dexos™. See
“Specification”
for more information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos™
specification and displaying the
dexos™certification mark are all
that is needed for good performance
and engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably.

Black plate (11,1)Chevrolet Impala Owner Manual - 2011
Vehicle Care 10-11
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
SeeDIC Warnings and Messages.
Change the oil as soon as possible
within the next 1 000 km (600 miles).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the
proper level. If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. Always reset the
engine oil life to 100% after every oil
change. It will not reset itself.
To reset the system:
1. Display OIL LIFE REMAINING
on the DIC.
2. Press and hold the SET/RESET button on the DIC for more than
five seconds. The oil life will
change to 100%.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
A good time to check the automatic
transmission fluid level is when the
engine oil is changed.
Change the fluid and filter at the
intervals listed in Scheduled
Maintenance on page 11‑2, and be
sure to use the transmission fluid
listed in Recommended Fluids and
Lubricants on page 11‑6.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, it may be decided to
have this done at the dealer service
department.
If not taken to the dealer, be sure
to follow all the instructions here,
or a false reading on the dipstick
could result.
