TOYOTA PREVIA 91-97 REPAIR MANUAL

GENERAL INFORMATION AND MAINTENANCE 1-19

Proper maintenance and tune-up is the key to long and trouble-free

vehicle life, and the work can yield its own rewards. Studies have shown

that a properly tuned and maintained vehicle can achieve better gas mileage

than an out-of-tune vehicle. As a conscientious owner and driver, set aside

a Saturday morning, say once a month, to check or replace items which

could cause major problems later. Keep your own personal log to jot down

which services you performed, how much the parts cost you, the date, and

the exact odometer reading at the time. Keep all receipts for such items as

engine oil and filters, so that they may be referred to in case of related

problems or to determine operating expenses. As a do-it-yourselfer, these

receipts are the only proof you have that the required maintenance was per-

formed. In the event of a warranty problem, these receipts will be invalu-

able.

The literature provided with your vehicle when it was originally delivered

includes the factory recommended maintenance schedule. If you no longer

have this literature, replacement copies are usually available from the

dealer. A maintenance schedule is provided later in this section, in case you

do not
