Engine Oil
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. 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 9‑6for 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 this is not
done, 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.

Vehicle Care 9-13
.GM6094M
Use only an oil that meets GM
Standard GM6094M.
.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 certified by the American
Petroleum Institute (API).Notice:
Use only engine oil
identified as meeting GM
Standard GM6094M and showing
the American Petroleum Institute
Certified For Gasoline Engines
starburst symbol. Failure to use
the recommended oil can result
in engine damage not covered by
the vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold, where
the temperature falls below −29°C
(−20°F), use either an SAE 5W-30
synthetic oil or an SAE 0W-30
engine oil. Both provide easier cold
starting for the engine at extremely
low temperatures. Always use an oil
that meets the required
specification, GM6094M.Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the starburst
symbol that meet GM Standard GM6094M are all that is needed for
good performance and engine
protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.

9-14 Vehicle Care
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A Change Engine Oil
Soon message comes on. See
Engine Oil Messages
on
page 4‑35. Change the oil as soon
as possible within the next 1 000 km
(600 miles). It is possible that,
if driving under the best conditions,
the oil life system might not indicate
that an oil change is necessary for
over a year. However, the engine oil
and filter must be changed at least
once a year and at this time the
system must be reset. Your dealer/
retailer has trained service people
who will perform this work using
genuine parts and reset the system.
It is also important to check the oil
regularly and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
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
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the key to ON/RUN with the engine off.
2. Press the DIC menu button on the turn signal lever to scroll
through the menu items on the
DIC screen.
3. Press the set button to clear the Change Engine Oil Soon
message and/or restore the
Remaining Oil Life 100%
message.
4. Turn the key to LOCK/OFF.
The system is reset when the
Change Engine Oil Soon message
is off and the Remaining Oil Life
100% message is is displayed.
What to Do with Used Oil
Used engine oil contains certain
elements that can 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 filter 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. Recycle it by taking it to a
place that collects used oil.

Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer/retailer service department
and have it repaired as soon as
possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, you should
have this done at your dealer/
retailer service department. Contact
your dealer/retailer for additional
information or the procedure can be
found in the service manual. To
purchase a service manual, see
Service Publications Ordering
Information on page 12‑12.Change the fluid and filter at the
intervals listed in
Scheduled
Maintenance
on page 10‑2, and be
sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 10‑7.
Engine Air Cleaner/Filter
The engine air cleaner/filter is
located in the engine compartment
on the driver's side of the vehicle.
See Engine Compartment Overview
on page 9‑6for more information
on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
Maintenance IIintervals and replace
it at the first oil change after each
80 000 km (50,000 mile) interval.
See Scheduled Maintenance
on
page 10‑2for more information.
If you are driving in dusty/dirty
conditions, inspect the filter at each
engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains caked with dirt, a new filter
is required.
To inspect or replace the engine air
cleaner/filter do the following:
2.4 L L4 Engine
1. Remove the screws on top of the engine air cleaner/filter
housing.

10-2 Service and Maintenance
{WARNING
Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer/
retailer to have a qualified
technician do the work.
SeeDoing Your Own Service
Work on page 9‑4.
At your General Motors dealer/
retailer, you can be certain that you
will receive the highest level of
service available. Your dealer/
retailer has specially trained
service technicians, uses genuine GM replacement parts, as well as,
up to date tools and equipment
to ensure fast and accurate
diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed in
Recommended Fluids and
Lubricants
on page 10‑7and
Maintenance Replacement Partson
page 10‑9. We recommend the
use of genuine parts from your
dealer/retailer.
Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed
when they have 8 000 to 13 000 km
(5,000 to 8,000 miles). See Tire
Rotation on page 9‑59.
Scheduled
Maintenance
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter.
See Engine Oilon page 9‑11.
An Emission Control Service.
When the Change Engine Oil Soon
message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 miles. If driving under the best
conditions, the engine oil life system
might not indicate the need for
vehicle service for more than a year.
The engine oil and filter must be
changed at least once a year and
the oil life system must be reset.
Your dealer/retailer has trained
service technicians who will perform
this work and reset the system.
