service schedule BUICK LESABRE 2003 User Guide

Selecting the Right Schedule
First you'll need to decide which of the two schedules is
right for your vehicle. Here's how to decide which
schedule to follow:
Short Trip/City De®nition
Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:
·Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
·Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
·You frequently tow a trailer or use a carrier on top
of your vehicle.
·If the vehicle is used for delivery service, police,
taxi or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km):Engine Oil and Filter
Change (or 3 months, whichever occurs ®rst).
Every 6,000 Miles (10 000 km):Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection.
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement.
Every 50,000 Miles (83 000 km):Automatic Transaxle
Service (severe conditions only).
Every 100,000 Miles (166 000 km):Spark Plug Wire
Inspection. Spark Plug Replacement. Automatic
Transaxle Service (normal conditions).
Every 150 000 Miles (240 000 km):Cooling System
Service (or every 60 months, whichever occurs
®rst). Engine Accessory Drive Belt Inspection.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
6-5

Long Trip/Highway De®nition
Follow this scheduled maintenanceonlyif none of the
conditions from the Short Trip/City Scheduled
Maintenance are true. Do not use this schedule if the
vehicle is used for trailer towing, driven in a dusty area
or used off paved roads. Use the Short Trip/City
schedule for these conditions
Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break down
slower.
Long Trip/Highway Intervals
Every 7,500 Miles (12 500 km):Engine Oil and Filter
Change (or every 12 months, whichever occurs
®rst). Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection.
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement.
Every 50,000 Miles (83 000 km):Automatic Transaxle
Service (severe conditions only).Every 100,000 Miles (166 000 km):Spark Plug Wire
Inspection. Spark Plug Replacement. Automatic
Transaxle Service (normal conditions.)
Every 150,000 Miles (240 000 km):Cooling System
Service (or every 60 months, whichever occurs
®rst). Engine Accessory Drive Belt Inspection.
These intervals only summarize maintenance services.

Footnotes
²The 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 engine oil
and ®lter. 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 ®lter 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 Engine Oil on
page 5-13
for information on resetting the system.
Whenever the tires are rotated, the Check Tire Pressure
System (if equipped) must be reset.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-22.

purchase/lease customers in conjunction with the
Bumper-to-Bumper coverage provided by the New
Vehicle Limited Warranty. Several transportation options
are available when warranty repairs are required.
This will reduce your inconvenience during warranty
repairs.
Plan Ahead When Possible
When your vehicle requires warranty service, you
should contact your dealer and request an appointment.
By scheduling a service appointment and advising
your service consultant of your transportation needs,
your dealer can help minimize your inconvenience.
If your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem is
safety-related. If it is, please call your dealership, let
them know this, and ask for instructions.
If the dealer requests that you simply drop the vehicle
off for service, you are urged to do so as early in
the work day as possible to allow for same day repair.
7-7

Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait Buick helps
minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealers can provide you with shuttle
service to get to your destination with minimal
interruption of your daily schedule. This includes a one
way shuttle ride to a destination up to 10 miles from
the dealership.
Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight warranty repairs,
reimbursement up to $30 per day (®ve days maximum)
may be available for the use of public transportation
such a s taxi or bus. In addition, should you arrange
transportation through a friend or relative,
reimbursement for reasonable fuel expenses up to
$10 per day (®ve day maximum may be available).
Claim amounts should re¯ect actual costs and be
supported by original receipts.
Courtesy Rental Vehicle
When your vehicle is unavailable due to overnight
warranty repairs, your dealer may arrange to provide
you with a courtesy rental vehicle or reimburse you for a
rental vehicle you obtained, at actual cost, up to a
maximum of $30.00 per day supported by receipts. This
requires that you sign and complete a rental agreement
and meet state, local and rental vehicle provider
requirements. Requirements vary and may include
minimum age requirements, insurance coverage, credit
card, etc. You are responsible for taxes, levies,
usage fees, excessive mileage or rental usage beyond
the completion of the repair.

courtesy rental.
