2007 CHEVROLET COBALT oil change

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine will continue
cranking for a few seconds or until the vehicle
starts. If the engine does not start and the key
is held in START for many seconds, cranking
will be stopped after 15 seconds to prevent
cranking motor damage. To prevent gear
damage, this system also prevents cranking if
the engine is already running. Engine cranking
can be stopped by turning the ignition switch to
the ACC or LOCK position.
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 allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor 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 briey but
then stops again, do the same thing. This
clears the extra gasoline from the engine.
Do not race the engine immediately after
starting it. Operate the engine and transaxle
gently until the oil warms up and lubricates all
moving parts.
Notice:Your engine is designed to work with
the electronics in your 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, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.

per gallon (mpg) or liters per 100 kilometers
(L/100 km) your vehicle is getting based on
current and past driving conditions.
Press and hold the reset button while ECON is
displayed to reset the average fuel economy.
Average fuel economy will then be calculated
starting from that point. If the average fuel
economy is not reset, it will be continually
updated each time you drive.

displayed. The engine oil life system shows
an estimate of the oil’s remaining useful life. It will
show 100% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual.
SeeEngine Oil on page 293andScheduled
Maintenance on page 396.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life
System” underEngine Oil Life System on
page 298.

oil has expired and it should be changed.
When you acknowledge the CHANGE OIL SOON
message by clearing it from the display, you
still must reset the engine oil life system
separately. SeeEngine Oil Life System on
page 298andScheduled Maintenance on
page 396for more information.
CHECK GAS CAP
This message displays if the fuel cap has not
been fully tightened. Recheck the fuel cap to
make sure that it is on properly. A few driving
trips with the cap properly installed should turn
the message off.

Notice:If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
have the starburst
symbol on the
container. This
symbol indicates
that the oil has been
certied by the
American Petroleum
Institute (API).Look for this on the oil container, and use only
those oils that are identied as meeting GM
Standard GM4718M and have the starburst
symbol on the front of the oil container.
Your vehicle’s engine is lled at the factory with
a synthetic oil which meets all requirements
for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard
GM4718M may not be available. You can add
substitute oil designated SAE 5W-30 with the
starburst symbol at all temperatures. Substitute oil
not meeting GM Standard GM4718M should not be
used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
standards are all you need for good performance
and engine protection.

Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter.
This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change
will be indicated can vary considerably. For the
oil life system to work properly, you must reset
the system every time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE OIL SOON message in
the Driver Information Center (DIC) will come on.
SeeDIC Warnings and Messages on page 184.
Change your oil as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the oil life system
may not indicate that an oil change is necessary for
over a year. However, your engine oil and ltermust be changed at least once a year and at this
time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system.
It is also important to check your oil regularly and
keep it at the proper level.
If the system is ever reset accidentally, you
must change your oil at 3,000 miles (5 000 km)
since your last oil change. Remember to reset the
oil life system whenever the oil is changed.
How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change
your oil prior to a CHANGE OIL SOON message
being turned on, reset the system.
298

After changing the engine oil, the system must be
reset as follows:
1. Turn the ignition to RUN, with the engine off.
2. Press the information and reset buttons
on the DIC at the same time to enter the
personalization menu. SeeDIC Vehicle
Personalization on page 186.
3. Press the information button to scroll through
the available personalization menu modes
until the DIC display shows OIL-LIFE RESET.
4. Press and hold the reset button until the DIC
display shows ACKNOWLEDGED. This will
tell you the system has been reset.
5. Turn the key to LOCK.
If the CHANGE OIL SOON message comes back
on when you start your vehicle, the engine oil
life system has not reset. Repeat the reset
procedure.What to Do with Used Oil
Used engine oil contains certain elements that may
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 lter before disposal. Never dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station,
or a local recycling center for help.
