{WARNING
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you
have to. If you have left the
engine running, the vehicle can
move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park on
page 9‑21. If you are pulling a
trailer, see Trailer Towing on
page 9‑46. 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
brake pedal then press the shift
lever button before you can shift
from P (Park) while the ignition key
is in ON/RUN. If you cannot shift
out of P (Park), ease pressure on
the shift lever and push the shift
lever all the way into P (Park) as
you maintain brake application.
Then move the shift lever into
another gear. See
Shifting 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.
M (Manual Mode): This position,
allows you to change gears similar
to a manual transmission. If the
vehicle has this feature, see Driver
Shift Control (DSC).
Manual Mode
Driver Shift Control (DSC)
To use this feature, do the following:
1. Move the shift lever from D (Drive) rearward to
M (Manual).
While driving in manual mode,
the transmission will remain
in the driver selected gear.
When coming to a stop in the
manual position, the vehicle
will automatically shift into
2 (Second) gear.

2. Press the + (plus) end of thebutton on the side of the shifter
to upshift, or push the −(minus)
end of the button to downshift.
The Driver Information Center (DIC)
in the instrument cluster will
change from the currently displayed
message to the letter “M,”for
Manual position, and a number
indicating the requested gear. While using the DSC feature the
transmission will have firmer shifting
and sportier performance. You can
use this for sport driving or when
climbing hills to stay in gear longer
or to downshift for more power or
engine braking.
The transmission will only allow you
to shift into gears appropriate for
the vehicle speed and engine
revolutions per minute (rpm):.The transmission will not
automatically shift to the next
higher gear if the vehicle speed
or engine rpm is too low.
.The transmission will not allow
shifting to the next lower gear if
the vehicle speed or engine rpm
is too high.
Second or Third Gear Start
Feature
When accelerating the vehicle
from a stop in snowy and icy
conditions, you may want to shift
into 2 (Second) or 3 (Third) gear.
A higher gear allows you to gain
more traction on slippery surfaces.
With the DSC feature, the vehicle
can be set to pull away in Second or
Third gear.
1. Move the shift lever from
D (Drive) into the
M (Manual Mode).
2. With the vehicle stopped, press (+) end of the button to
select 2 (Second) or 3 (Third)
gear. The vehicle will start from
a stop position in 2 (Second) or
3 (Third) gear.
3. Once moving select the desired drive gear.

9-28 Driving and Operating
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 5‑19. 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.

Black plate (30,1)Chevrolet Malibu Owner Manual - 2012
9-30 Driving and Operating
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 the front wheels are
spinning too much or are beginning
to lose traction. When this happens,
the system works the front brakes
and reduces engine power by
closing the throttle and managing
engine spark to limit wheel spin.
This light will flash when the traction
control system is limiting wheel spin.The system may be heard or felt
while it is working, but this is
normal.
If the vehicle is in cruise control
when TCS begins to limit wheel
spin, the cruise control will
automatically disengage. The cruise
control may be re-engaged when
road conditions allow. See
Cruise
Control on page 9‑33.
When this light is on solid and
either the SERVICE TRACTION or
TRACTION OFF message is
displayed, the system will not limit
wheel spin.
Adjust your driving accordingly.
See Ride Control System Messages
on page 5‑28 for more information. The Traction Control System is
automatically enabled whenever the
vehicle is started. To limit wheel
spin, especially in slippery road
conditions, always leave the system
enabled. TCS can be turned off if
needed.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice or snow,
and you want to
“rock”the 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.
To turn the system off or on, press
and release this button located on
the center console.

Black plate (31,1)Chevrolet Malibu Owner Manual - 2012
Driving and Operating 9-31
The traction off light comes on and
the DIC will display the appropriate
message as described previously
when the button is pressed.
Traction Control Operation
Traction control limits wheel spin by
reducing engine power to the
wheels (engine speed management)
and by applying brakes to each
individual wheel (brake-traction
control) as necessary.
The traction control system is
enabled automatically when the
vehicle is started, and it will activate
and flash the ESC/TCS light and
display the LOW TRACTION
message if it senses either of the
front wheels are spinning or
beginning to lose traction while
driving. For more information on theLOW TRACTION message, see
Ride Control System Messages on
page 5‑28.
Notice:
If the wheel(s) of one axle
are allowed to spin excessively
while the ESC/TCS, ABS and
Brake warning lights and the
SERVICE ESC and/or SERVICE
TRACTION messages are
displayed, the differential could
be damaged. The repairs would
not be covered by the vehicle
warranty. Reduce engine power
and do not spin the wheel(s)
excessively while these lights and
this message are displayed.
Notice: When traction control is
turned off, it is possible to lose
traction. If you attempt to shift
with the front wheels spinning
with a loss of traction, it is
possible to cause damage to the
transmission. Do not attempt to
shift when the front wheels do not
have traction. Damage caused by
misuse of the vehicle is not
covered. See your warranty book
for additional information. The traction control system may
activate on dry or rough roads or
under conditions such as heavy
acceleration while turning or
abrupt upshifts/downshifts of the
transmission. When this happens,
a reduction in acceleration may be
noticed, or a noise or vibration may
be heard. This is normal.
If the vehicle is in cruise control
when the system activates, the
ESC/TCS light will flash and the
cruise control will automatically
disengage. The cruise control
may be re-engaged when road
conditions allow. See
Cruise Control
on page 9‑33.
Adding non‐dealer accessories can
affect the vehicle's performance.
See Accessories and Modifications
on page 10‑3 for more information.

9-36 Driving and Operating
Fuel
Use of the recommended fuel is
an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
The eighth digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine.
The VIN is at the top left of the
instrument panel. SeeVehicle
Identification Number (VIN) on
page 12‑1.
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
See Fuel E85 (85% Ethanol) on
page 9‑39. For all other vehicles,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑36.
Recommended Fuel
If the vehicle has the 2.4L L4 engine
(VIN Code 1) or the 2.4L L4 engine
(VIN Code U), use regular unleaded
gasoline with a posted octane rating
of 87 or higher. If the octane rating
is less than 87, an audible knocking
noise, commonly referred to as
spark knock, might be heard when
driving. If this occurs, use a
gasoline rated at 87 octane or
higher as soon as possible. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
If the vehicle has the 3.6L V6 engine
(VIN Code 7), use regular unleaded
gasoline with a posted octane
rating of 87 or higher. For best
performance or trailer towing, you
could choose to use middle grade
89 octane unleaded gasoline.
If the octane rating is less than 87,
an audible knocking noise,
commonly referred to as spark
knock, might be heard when driving.

Black plate (37,1)Chevrolet Malibu Owner Manual - 2012
Driving and Operating 9-37
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. If heavy knocking is heard
when using gasoline rated at
87 octane or higher, the engine
needs service.
Gasoline Specifications
(U.S. and Canada Only)
At a minimum, gasoline should
meet ASTM specification
D 4814 in the United States or
CAN/CGSB‐3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel Additives
on page 9‑37 for additional
information.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications.
See the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See Malfunction Indicator Lamp on
page 5‑16. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
Never use leaded gasoline or any
other fuel not recommended in the
previous text on fuel. Costly repairs
caused by use of improper fuel
would not be covered by the vehicle
warranty.
To check the fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you will be driving.
Fuel Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives that
help prevent engine and fuel system
deposits from forming, allowing the
emission control system to work
properly. In most cases, nothing
should have to be added to the fuel.

Black plate (38,1)Chevrolet Malibu Owner Manual - 2012
9-38 Driving and Operating
However, some gasolines contain
only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean
and avoid problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed by
the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.For customers who do not use
TOP TIER Detergent Gasoline
regularly, one bottle of GM Fuel
System Treatment PLUS, added to
the fuel tank at every engine oil
change, can help clean deposits
from fuel injectors and intake
valves. GM Fuel System Treatment
PLUS is the only gasoline additive
recommended by General Motors.
It is available at your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must not be used in
vehicles that were not designed for
those fuels.Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
spark plug life and affect emission
control system performance.
The malfunction indicator lamp
might turn on. If this occurs, return
to your dealer for service.

Black plate (39,1)Chevrolet Malibu Owner Manual - 2012
Driving and Operating 9-39
Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
For all other vehicles, use only the
unleaded gasoline described under
Recommended Fuel on page 9‑36.
We encourage the use of E85 in
vehicles that are designed to use it.
The ethanol in E85 is a“renewable”
fuel, meaning it is made from
renewable sources such as corn
and other crops.
Many service stations will not have
an 85% ethanol fuel (E85) pump
available. The U.S. Department of
Energy has an alternative fuels
website (www.afdc.energy.gov/afdc/
locator/stations/) that can help you
find E85 fuel. Those stations that do
have E85 should have a label
indicating ethanol content. Do not
use the fuel if the ethanol content is
greater than 85%. At a minimum, E85 should meet
ASTM Specification D 5798 or
CGSB Specification 3.512. Filling
the tank with fuel mixtures that
do not meet ASTM or CGSB
specifications can affect driveability
and could cause the malfunction
indicator lamp to come on. As the
outside temperature approaches
freezing, ethanol fuel distributors
should supply winter grade ethanol,
the same as with unleaded
gasoline.
The starting characteristics of
E85 fuel make it unsuitable for
use when temperatures fall below
−18°C (0°F). In the range of
−18°C
(0°F) to 0°C (32°F), it may take
more time to start the engine.
It is best not to alternate repeatedly
between gasoline and E85. If you
do switch fuels, it is recommended
that you add as much fuel as
possible —do not add less than
11 L (3 gal) when refueling. You should drive the vehicle
immediately after refueling for at
least 11 km (7 mi) to allow the
vehicle to adapt to the change in
ethanol concentration.
E85 has less energy per liter
(gallon) than gasoline, so you will
need to refill the fuel tank more
often when using E85 than when
you are using gasoline. See
Filling
the Tank on page 9‑40.
Notice: Some additives are not
compatible with E85 fuel and can
harm the vehicle's fuel system.
Do not add anything to E85.
Damage caused by additives
would not be covered by the
vehicle warranty.
Notice: This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
