STABILITY SYSTEM DISABLED Message
The STABILITY SYSTEM
DISABLED message
indicates that the stability
enhancement system has
been temporarily disabled.
There are three conditions that can cause this message to
appear. One condition is overheating, which could
occur if the stability enhancement system activates
continuously for an extended period of time.
The STABILITY SYSTEM DISABLED message will
also be displayed if the brake system warning light is on.
See ªBrake System Warning Lightº in the Index.
Finally, the message could be displayed if the stability
system takes longer than usual to complete its diagnostic
checks due to driving conditions. The STABILITY
SYSTEM DISABLED message will turn off as soon as
the conditions that caused the message to be displayed
are no longer present. See ªStabilitrak Systemº in
the Index.
Secondary Information Center (SIC)
This section explains the features of your SIC.
The SIC provides instant information about fuel,
mileage and vehicle history in addition to allowing you
to personalize certain features of your vehicle. If you
would like to skip to the section on personalizing your
vehicle, see the section under MENU.

Fuel
Each press of the FUEL button will change the
display between the fuel remaining range, average
fuel economy, instantaneous fuel economy and a
blank display.
The average fuel economy can be reset using the
RESET button.
Trip
Each press of the TRIP button will change the display
between personal trip computer, business trip computer,
timer, vehicle history, annual mileage and a blank display.Personal Trip Computer and Business Trip Computer
Each press of the arrow button will change the
display between turn on/off, trip odometer,
fuel used, average fuel economy and average speed.
The ON/OFF button will turn the trip computer on
and off. The information on the trip computer only
gets updated when it is turned on. The personal and
business computers are independent, i.e. turning one
of them on does not turn the other off.
All information associated with the trip computer
will be reset when the RESET button is pressed.
If the RESET button is pressed and held for more
than two seconds, all of the trip computer settings
will reset starting from the last ignition cycle
(turning the ignition from OFF to RUN). This
feature is for someone who has forgotten to reset the
trip computer when pulling out of the driveway and
does not realize it until after driving for awhile.

Each press of the ON/OFF button will turn the timer
on or off.
The RESET button will reset the timer to 00:00:00.
If turned on, the timer will accumulate whenever
the SIC is powered (the engine does not have to
be running).
The timer will rollover after 99:59:59.
Vehicle History Last 15 Days
The first press of the arrow button will display the
maximum speed and accumulated mileage for the
current day.
Every press of the arrow button after will display the
maximum speed and accumulated mileage for the
previous day.
This feature requires the date and time to be set
correctly. Refer to the setting of day/date/time under
the MENU button explained later in this section.Annual Mileage
The annual mileage displayed is the mileage
accumulated since the annual mileage was reset.
Pressing the RESET button will reset the annual
mileage to 0.
Pressing the arrow button will display the ratio of
personal trip computer mileage to annual mileage as
a percent.
Pressing the arrow button again will display the ratio
of business trip computer mileage to annual mileage
as a percent.

Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you'll go to your dealer for
all your service needs. You'll get genuine GM parts and
GM
-trained and supported service people.
We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you'll
want to use the proper service manual. It tells you much
more about how to service your vehicle than this manual
can. To order the proper service manual, see ªService
and Owner Publicationsº in the Index.
Your vehicle has an air bag system. Before attempting
to do your own service work, see ªServicing Your Air
Bag
-Equipped Vehicleº in the Index.
You should keep a record with all parts receipts and
list the mileage and the date of any service work you
perform. See ªMaintenance Recordº in the Index.

As in the chart shown previously, SAE 5W-30 is best for
your vehicle. However, you can use SAE 10W
-30 if it's
going to be 0F (
-18C) or above. These numbers on an
oil container show its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 20W
-50.
NOTICE:
Use only engine oil with the American
Petroleum Institute Certified 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 where the temperature falls below
-20F (-29C), consider using either an SAE 5W-30
synthetic oil or an SAE 0W
-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
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 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 ENGINE OIL message will
come on. Change your oil as soon as possible within
the next two times you stop for fuel. 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, your engine oil and filter must
be changed at least once a year and at this time the
system must be reset. 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
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed.

An Emission Control Service.
Lubricate chassis components with each engine oil and
filter change. Lubricate the front suspension, ball joints,
steering linkage, transmission shift linkage and parking
brake cable guides. Ball joints should not be lubricated
unless their temperature is 10F (
-12C) or higher,
or they could be damaged.
