California Proposition 65
Warning
Most motor vehicles, including this
one, contain and/or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm. Engine
exhaust, many parts and systems,
many fluids, and some component
wear by-products contain and/or
emit these chemicals.
California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained in
remote keyless transmitters, may
contain perchlorate materials.
Special handling may be necessary.
For additional information, see
www.dtsc.ca.gov/hazardouswaste/
perchlorate.
Accessories and
Modifications
Adding non-dealer/non-retailer
accessories to the vehicle can affect
vehicle performance and safety,
including such things as airbags,
braking, stability, ride and handling,
emissions systems, aerodynamics,
durability, and electronic systems
like antilock brakes, traction control,
and stability control. Some of these
accessories could even cause
malfunction or damage not covered
by the vehicle warranty.
Damage to vehicle components
resulting from the installation or use
of non-GM certified parts, including
control module modifications, are
not covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.GM Accessories are designed to
complement and function with other
systems on the vehicle. Your GM
dealer/retailer can accessorize the
vehicle using genuine GM
Accessories. When you go to your
GM dealer/retailer and ask for GM
Accessories, you will know that
GM-trained and supported service
technicians will perform the work
using genuine GM Accessories.

10-8 Vehicle Care
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. SeeEngine
Compartment Overview
on
page 10‑6for 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.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add at
least one quart/liter of the
recommended oil. This section
explains what kind of oil to use. For
engine oil crankcase capacity, see
Capacities and Specifications
on
page 12‑2. Notice:
Do not add too much oil.
If the engine has so much oil that
the oil level gets above the
cross-hatched area that shows
the proper operating range, the
engine could be damaged.
See Engine Compartment Overviewon page 10‑6for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range in the cross-hatched area.
Push the dipstick all the way back in
when through.

Vehicle Care 10-9
What Kind of Engine Oil to Use
Look for three things:
.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 −20°F
(−29°C), 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. See “What
Kind of Engine Oil to Use” for more
information.

10-10 Vehicle Care
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.
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.
Change the oil as soon as possible
within the next 600 miles (1 000 km).
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 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 the
engine oil and filter based on
vehicle use. Whenever the oil is
changed, reset the system so it can
calculate when the next oil change
is required. If a situation occurs
where the oil is changed prior to a
CHANGE ENGINE OIL SOON
message being turned on, reset the
system.

Vehicle Care 10-11
To reset the Engine Oil Life System:
1. Turn the ignition to ON/RUN,with the engine off.
2. Press the vehicle information button until OIL LIFE
REMAINING displays.
3. Press and hold the set/reset button until 100% is displayed.
Three chimes sound and the
CHANGE ENGINE OIL SOON
message goes off.
4. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.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
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 the
dealer/retailer and have it repaired
as soon as possible.
Change the fluid at the intervals
listed in Scheduled Maintenance
on
page 11‑2, and be sure to use the
transmission fluid listed in
Recommended Fluids and
Lubricants on page 11‑7.
