2006 PONTIAC G6 adding oil

LOW OIL LEVEL:This message may display on some
vehicles. For correct operation of the low oil sensing
system, your vehicle should be on a level surface.
A false LOW OIL LEVEL message may appear if the
vehicle is parked on a grade. The oil level sensing
system does not check for actual oil level if the engine
has been off for a short period of time, and the oil
level is never checked while the engine is running. If the
LOW OIL LEVEL message appears, and your vehicle
has been parked on level ground with the engine off for
at least 30 minutes, the oil level should be checked
by observing the oil dipstick. Prior to checking the
oil level, be sure the engine has been off for a few
minutes and your vehicle is on a level surface. Then
check the dipstick and add oil if necessary. SeeEngine
Oil on page 5-17.
LOW WASHER FLUID:This message will display
when your vehicle is low on windshield washer uid. You
should rell the windshield washer uid reservoir as
soon as possible. See “Adding Washer Fluid” under
Windshield Washer Fluid on page 5-38.
PARKING BRAKE:This message will display if the
parking brake is left engaged and you try to drive away.
SeeParking Brake on page 2-33for more information.
POWER STEERING:This message will display if
a problem has been detected with the electric power
steering, if equipped. Have your vehicle serviced
immediately by your GM dealer.SERVICE AIR BAG:There is a problem with the airbag
system when this message appears. Have your

Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice:If you use the proper coolant, you do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.

Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
1. You can remove the coolant surge tank pressure
cap when the cooling system, including the coolant
surge tank pressure cap and upper radiator
hose, is no longer hot. Turn the pressure cap
slowly counterclockwise about two or two and
one-half turns.
If you hear a hiss, wait for that to stop. This will
allow any pressure still left to be vented out
the discharge hose.
