mileage BUICK LESABRE 2002 Owner's Manual

2-70 Speedometer and 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 or kilometers. Press The ENG/MET
button which is located to the left of the speedometer
to change from mph to km/h.
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 it must be.
But 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.
Trip Odometer
A trip odometer can tell you how far you have driven
since you last set it to zero. To reset it, push the TRIP
RESET button. If your vehicle is equipped with a DIC,
see ªDriver Information Center (DIC)º in the Index for
information on resetting the trip odometer.
Tachometer (If Equipped)
The tachometer tells you
how fast the engine is
running. It displays engine
speed in thousands of
revolutions per minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the shaded area or engine damage may occur.

Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver
Information Center (DIC). The DIC will display
information about how your vehicle is functioning,
as well as warning messages if a system problem is
detected. This feature also allows two different drivers
to store and recall their own personal choice settings.
See ªDIC Personal Choice Programmingº later in
this section.
DIC Displays and Controls
There are two lines in the DIC display. The DIC
displays the driver number identified when entering the
vehicle. You can have your dealer program your name to
appear on this display line. See your dealer for more
information.
When you turn the ignition on, the DIC will display
your DRIVER NUMBER. The system will then perform
a status check and display any messages if a problem
is detected.
If there are no problems detected, the display will return
to the mode selected by that driver the last time the
ignition was turned off.If a problem is detected, a diagnostic message will
appear in the display. The following pages will show
the messages you may see on the DIC display.
The message center is continuously updated with the
vehicle's performance status.
The following buttons are
on the DIC control panel
which is located to the left
of the steering column:
ODO/TRIP (Odometer/Trip): When this button is
pressed, the display will show the total mileage, and
Trip 1 or Trip 2 miles. Trip 1 and Trip 2 will display the
miles traveled since the last reset. To reset the trip
odometer, press the ODO/TRIP button until the
preferred trip number (1 or 2) is shown in the DIC
display, then press the RESET button. The trip odometer
will now accumulate miles until the next reset.

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 When to Change Engine Oil (Vehicles With
the GM Oil Life System
Option)
If so equipped, 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 SOON 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.
How to Reset the Oil Life System (If Equipped)
The GM Oil Life System
calculates when to change
your engine oil and filter 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
ENGINE OIL SOON message being turned on, reset
the system.
To reset the Oil Life System, do the following:
1. Display the OIL LIFE INDEX on the DIC.
2. Press and hold the RESET button on the DIC
for more than five seconds. The oil life will change
to 100%.

Short Trip/City Scheduled Maintenance
7-8
The services shown in this schedule up to 100,000 miles
(166 000 km) should be repeated after 100,000 miles
(166 000 km) at the same intervals for the life of
this vehicle. The services shown at 150,000 miles
(240 000 km) should be repeated at the same interval
after 150,000 miles (240 000 km) for the life of
this vehicle.
See ªOwner Checks and Servicesº and ªPeriodic
Maintenance Inspectionsº following.Footnotes

The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle's useful life. We, however,
urge that all recommended maintenance services
be performed at the indicated intervals and the
maintenance be recorded.
* If your vehicle has the GM Oil Life System, a
computer system lets you know when to change the 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.
