If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center (DIC)
appears, check the engine oil level right away.
For more information, see LOW OIL LEVEL and
LOW OIL PRESSURE underDIC Warnings and
Messages on page 3-60. Check the engine oil level
regularly; this is an added reminder.
Checking Engine Oil
It is a good idea to check the 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 6-12for
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 Kind of Engine Oil to Use
Look for three things:
GM4718M
This vehicle’s engine requires a special oil meeting
GM Standard GM4718M. Oils meeting this standard
may be identied as synthetic. However, not all
synthetic oils will meet this GM standard. Use only
an oil that meets GM Standard GM4718M.Notice:Using oils that do not have the GM4718M
Standard designation can cause engine damage not
covered by the vehicle warranty.
SAE 5W-30
SAE 5W-30 is best for the vehicle. These numbers
on an oil container show its viscosity, or thickness.
Do not use other viscosity oils such as SAE 20W-50.
American Petroleum Institute (API) starburst symbol
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).
This vehicle’s engine was lled at the factory with a
Mobil 1
®synthetic oil meeting all requirements for this
vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
might 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 Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in the vehicle for ve years or
150,000 miles (240 000 km), whichever occurs rst.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a
problem with the engine overheating, seeEngine
Overheating on page 6-27.
What to Use
{CAUTION:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch re and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing else
needs to be added. This mixture:
Gives freezing protection down to−34°F (−37°C),
outside temperature.
Gives boiling protection up to 265°F (129°C),
engine temperature.
Protects against rust and corrosion.
Will not damage aluminum parts.
Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 7-11for more information.
