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.
SeeEngine Compartment Overview on page 242
for 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 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.

When to Add Engine Oil
If the oil is below the MIN (minimum) mark, you
will need to add at least one quart/liter of oil.
But you must use the right kind. This section
explains what kind of oil to use. For engine
oil crankcase capacity, seeCapacities and
Specications on page 331.
Notice:Do not add too much oil. If the
engine has so much oil that the oil level
gets above the upper mark that shows the
proper operating range, the engine could
be damaged.SeeEngine Compartment Overview on page 242
for the location of the engine oil ll cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range.
Push the dipstick all the way back in when
you are through.

What Kind of Engine Oil to Use
For Vehicles With the 2.0L L4 Engine
Look for two things:
GM4718M
Your vehicle’s engine requires a special oil
meeting GM Standard GM4718M, such as
Mobil 1
®or equivalent. Oils meeting this
standard may be identied as synthetic.However, not all synthetic oils will meet this
GM standard. You should look for and use only
an oil that meets GM Standard GM4718M.
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
also have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certied by the
American Petroleum
Institute (API).
You should 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.For Vehicles With the 2.4L L4 Engine
Look for two things:
GM6094M
Your vehicle’s engine requires oil meeting
GM Standard GM6094M. You should look for
and use only an oil that meets GM Standard
GM6094M.

and have the starburst symbol on the front of
the oil container.Notice:Use only engine oil identied as
meeting GM Standard GM6094M and showing
the American Petroleum Institute Certied
For Gasoline Engines starburst symbol. Failure
to use the recommended oil can result in
engine damage not covered by your warranty.
GM Goodwrench
®oil meets all the requirements
for your vehicle.
If you are in an area of extreme cold, where
the temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will need for
good performance and engine protection.

Engine Oil Life System
When to Change Engine Oil
Your vehicle has the Engine Oil Life System,
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
will come on. SeeDIC Warnings and Messages
on page 147. Change the 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, the
engine oil and lter must be changed at least once
a year and at this time the system must be reset.Your retailer has trained service people who will
perform this work using genuine Saturn 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 the oil at 3,000 miles (5 000 km) since
the 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.
250
ProCarManuals.com

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 Driver Information Center (DIC) at
the same time to enter the personalization
menu. SeeDIC Vehicle Personalization
on page 152.
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
used oil, ask your retailer, a service station, or a
local recycling center for help.

When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter element at each
scheduled MaintenanceIIservice interval and
replace the air cleaner/lter element at the
rst oil change after 50,000 miles (85 000 km).
If you are driving in dusty/dirty conditions,
inspect the lter at each engine oil change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect the air cleaner/lter remove the lter
from the vehicle and lightly shake the lter to
release loose dust and dirt. If the lter remains
caked with dirt, a new lter is required.
To inspect or replace the lter, open the clamps
that hold the cover on and lift off the cover.
Be sure to reinstall the cover tightly.
{CAUTION:
Operating the engine with the air
cleaner/lter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop ames if
the engine backres. If it is not there
and the engine backres, you could be
burned. Do not drive with it off, and be
careful working on the engine with the
air cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre
can cause a damaging engine re. And, dirt
can easily get into your engine, which will
damage it. Always have the air cleaner/lter
in place when you are driving.

Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years
or 150,000 miles (240 000 km), whichever
occurs rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 258.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would
not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
