2002 Oldsmobile Silhouette mileage

Speedometer and Tamper
Resistant Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has been
driven, in either miles (used in the United States) or
kilometers (used in Canada).
Your vehicle has a tamper
-resistant odometer.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
If it can't, then it's set at zero and a label must be put on
the driver's door to show the old mileage reading when
the new odometer was installed.
Dual Trip Odometers
In addition to the standard odometer, the cluster can also
display two separate trip odometers (designated by the
letter A or B in the display window) as well as your
vehicle's Engine Oil Life (designated by the word OIL
in the display window). The display can be toggled
between the odometer, the trip odometers and engine oil
life by quickly pressing and releasing the trip/reset
button located to the right of the temperature gage.
The display toggles once each time the trip/reset button
is pressed for less than 1.5 seconds. The display toggles
in the following sequence: Odometer
- Trip Odometer
A
- Trip Odometer B - Engine Oil Life. If the engine
oil life is left on the display, it will automatically toggle
back to the odometer after approximately 15 seconds.
Each of the two trip odometers can be used to keep track
of different trip distances (for example, the mileage of a
long trip and the mileage driven on the current tank of
fuel). The trip odometers will continue to keep track of
miles (kilometers) driven even if they are not currently
displayed. To reset the odometer to zero (0), press and
hold the trip/reset button for at least 1.5 seconds, but less
than three seconds. Only the trip odometer that is
showing in the display will be reset.

2-98
Retro-Active Reset
Each of the two trip odometers has a feature called
retro
-active reset. This feature can be used to set either
(or both) trip odometer(s) to the number of miles
(kilometers) driven since the ignition was last turned on.
This can be used if you forget to reset your trip
odometer at the beginning of a trip. To use the
retro
-active reset feature, press and hold the trip/reset
button for at least three seconds. The trip odometer will
then display the number of miles (kilometers) driven
since the ignition was last turned on and you began
driving. (If you use the retro
-active reset feature after
you have started the vehicle, but before you begin
moving, the display will show the number of miles
(kilometers) you drove during the last ignition cycle.)
Once you begin driving, the trip odometer will
accumulate mileage. For example, if you have driven
5.0 miles (8.0 km) since you started your vehicle, and
then activate the retro
-active reset feature, the display
will show 5.0 miles (8.0 km). As you drive, the display
will then increase to 5.1 (8.2 km), 5.2 (8.4 km), etc.
Only the trip odometer that is displayed will be affected
by the retro
-active reset so that both trip odometers can
be used separately.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.

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.

6-15
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.

Change engine oil and filter as indicated by the
GM Oil Life System
(or every 12 months,
whichever occurs first). Reset the 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. See ªOil Life Systemº in the Index
for information on resetting the system.
An Emission Control Service.
Lubricate chassis components with each engine oil and
filter change. Lubricate the suspension, steering linkage,
transaxle shift linkage, and the underbody contact points
and linkage.
