2009 CHEVROLET CORVETTE engine oil

If the temperature overheat gage is no longer in the
overheat zone or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive
the vehicle slow for about 10 minutes. Keep a safe
vehicle distance from the car in front of you. If the
warning does not come back on, continue to drive
normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
three minutes while parked. If the warning is still
displayed, turn off the engine until it cools down.
Also, see “Overheated Engine Protection Operating
Mode” next in this section.Overheated Engine Protection
Operating Mode
This emergency operating mode lets the vehicle
be driven to a safe place, up to 50 miles (80 km),
in an emergency situation. If an overheated engine
condition exists and the messages COOLANT OVER
TEMPERATURE and REDUCED ENGINE POWER
are displayed, along with the check engine light, an
overheat protection mode which alternates ring groups
of cylinders helps prevent engine damage. In this mode,
there is a signicant loss in power and engine
performance.
Driving extended distances in the overheat protection
mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair the
cause of coolant loss, change the oil and reset the oil
life system. SeeEngine Oil on page 5-20.

Checking Brake Fluid
Check brake uid by looking at the brake uid reservoir.
SeeEngine Compartment Overview on page 5-14.
The uid level should be above the MIN mark on the
reservoir. If it is not, have the brake hydraulic system
checked to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the level is between the MIN and MAX marks.
What to Add
Use only new DOT-3 brake uid from a sealed
container. SeeRecommended Fluids and Lubricants
on page 6-12.
Always clean the brake uid reservoir cap and the area
around the cap before removing it. This helps keep
dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake uid.
Notice:
Using the wrong uid can badly damage brake
hydraulic system parts. For example, just a few
drops of mineral-based oil, such as engine oil, in
the brake hydraulic system can damage brake
hydraulic system parts so badly that they will
have to be replaced. Do not let someone put in
the wrong kind of uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on the vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 5-95.

4. Open the hoods and locate the positive (+) and
negative (−) terminal locations on each vehicle.
6.2 L LS3 shown, 7.0 L LS7 and 6.2 L LS9 similar.
Your vehicle has a remote positive (+) terminal (A)
and a remote negative (−) terminal (B), as shown in
the illustration, which should be used to jump start
your vehicle.The remote positive (+) terminal (A) can be
accessed by opening the cover of the engine
compartment fuse block.
The remote negative (−) terminal (B) is located
underneath the engine cover, below the engine
oil ll cap.
SeeEngine Compartment Overview on page 5-14
for the location of the engine compartment fuse
block and engine oil ll cap.
You will not need to access the battery for jump
starting. The remote terminals are for that purpose.
{CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements the vehicle warranties. See the Warranty
and Owner Assistance booklet or your dealer/retailer for
details.
Maintenance Requirements
Notice:Maintenance intervals, checks, inspections,
replacement parts, and recommended uids and
lubricants as prescribed in this manual are necessary
to keep this vehicle in good working condition. Any
damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep
the vehicle in good working condition, but also helps
the environment. All recommended maintenance is
important. Improper vehicle maintenance can even affect
the quality of the air we breathe. Improper uid levels or
the wrong tire ination can increase the level of emissions
from the vehicle. To help protect the environment, and to
keep the vehicle in good condition, be sure to maintain
the vehicle properly.
Using the Maintenance Schedule
We want to help keep this vehicle in good working
condition. But we do not know exactly how you will drive
it. You might drive very short distances only a few
times a week. Or you might drive long distances all the
time in very hot, dusty weather. You might use the
vehicle in making deliveries. Or you might drive
it to work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You might need more
frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep the vehicle in good condition,
see your dealer/retailer.

Scheduled Maintenance
When the CHANGE ENGINE OIL message displays,
service is required for the vehicle. Have the vehicle
serviced as soon as possible within the next 600 miles
(1 000 km). It is possible that, if driving under the
best conditions, the engine oil life system may not
indicate that vehicle service is necessary for over a year.
However, the engine oil and lter must be changed at
least once a year and at this time the system must
be reset. Your dealer/retailer has trained service
technicians who will perform this work using genuine
parts and reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-26for information on the Engine
Oil Life System and resetting the system.When the CHANGE ENGINE OIL message appears,
certain services, checks, and inspections are required.
Required services are described in the following for
“MaintenanceI” and “MaintenanceII.” Generally, it is
recommended that the rst service be MaintenanceI,
the second service be MaintenanceII, and then alternate
MaintenanceIand MaintenanceIIthereafter. However,
in some cases, MaintenanceIImay be required more
often.
MaintenanceI— Use MaintenanceIif the message
displays within 10 months since the vehicle was
purchased or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message displays
10 months or more since the last service or if the
message has not come on at all for one year.

dependability, and emission control performance. Your
dealer/retailer can assist with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to the
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-12.
At Each Fuel Fill
It is important to perform these underhood checks at
each fuel fill.
Engine Oil Level Check
Notice:It is important to check the engine oil
regularly and keep it at the proper level. Failure to
keep the engine oil at the proper level can cause
damage to the engine not covered by the vehicle
warranty.
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-20.
