engine CHEVROLET MALIBU 2007 6.G Service Manual

Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 346. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration.
(These conditions may go away once the engine
is warmed up.) This will be detected by the
system and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require
at least one full tank of the proper fuel to turn
the light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed
to evaluate critical emission control systems
during normal driving. This may take several
days of routine driving. If you have done this and
your vehicle still does not pass the inspection
for lack of OBD system readiness, your dealer
can prepare the vehicle for inspection.

Oil Pressure Light
If your vehicle has low
engine oil pressure,
this light will stay on after
you start your engine,
or come on and you
will hear a chime when
you are driving.
This indicates that your engine is not receiving
enough oil. The engine could be low on oil,
or could have some other oil problem.
Have it xed immediately.
This light will come on briey when you turn
on the ignition as a check to show you it is
working. If it does not come on with the ignition
on, you may have a problem with the bulb.
Have it xed right away.{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become
so hot that it catches re. You or others
could be burned. Check your oil as
soon as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

Information Mode
INFO/4(Information):Press this button to scroll
through the vehicle information mode displays
in the following order:
TRIP A
TRIP B
FUEL RANGE (Fuel Range Until Empty)
ECON (Average Fuel Economy)
AV SPEED (Average Vehicle Speed)
OIL LIFE (Engine Oil Life System)
TRIP A or TRIP B:Press the information
button until TRIP A or TRIP B is displayed.
This shows the current distance traveled since
the last reset for each trip odometer in either
miles (mi) or kilometers (km). Both odometers
can be used at the same time. Each trip odometer
can be reset to zero separately by pressing and
holding the enter button for a few seconds
while the desired trip odometer is displayed.FUEL RANGE:Press the information button
until FUEL RANGE is displayed. This shows
the remaining distance you can drive without
refueling. It is based on fuel economy and
the fuel remaining in the tank.
When the fuel level is low, FUEL RANGE LOW
displays.
The fuel economy data used to determine fuel
range is an average of recent driving conditions.
As your driving conditions change, this data is
gradually updated. Fuel range cannot be reset.
ECON (Economy):Press the information
button until ECON is displayed. Average fuel
economy is how many miles 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 enter 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.
219

AV (Average) SPEED:Press the information
button until AV SPEED is displayed. This shows
the vehicle’s average speed in miles per hour (mph)
or kilometers per hour (km/h).
Press and hold the enter button while AV SPEED
is displayed to reset the average vehicle speed.
OIL LIFE:Press the information button until
OIL LIFE is displayed. The engine oil life system
shows an estimate of the oil’s remaining useful life.
It shows 100% when the system is reset after
an oil change. It will alert you to change the oil on
a schedule consistent with your driving conditions.
Always reset the engine oil life system after
an oil change. SeeEngine Oil Life System
on page 362.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual.
SeeScheduled Maintenance on page 460and
Engine Oil on page 359.Personalization
