service interval TOYOTA PRIUS 2003 1.G Scheduled Maintenance Guide

Safety Precautions
Your Toyota Prius has both high-voltage DC and AC systems as well as a 12-volt
system. Both DC and AC high voltage are very dangerous and can cause personal
injury, severe burns, electric shock and even fatal injury.
To avoid personal injury, please follow all caution labels attached to high-voltage
parts. Do not touch or attempt to remove orreplace any high-voltage (orange-
colored) wiring and connectors. Do not touch the service plug located in the
driver’s side trim of the trunk.
If an accident occurs, do not touch any high-voltage wiring, connectors or parts
such as the inverter unit or hybrid vehicle battery assembly.
Do not touch the potassium hydroxide electrolyte that might spill or leak from
the hybrid vehicle battery as the resultof an accident. If potassium hydroxide
electrolyte gets on your skin or in your eyes, neutralize it immediately with a
saturated boric acid solution (ratio: 80 grams boric acid to two liters water).
Seek immediate medical attention.
If a vehicle fire occurs, extinguish it with a Class D powder-type fire extinguisher.
Complimentary Maintenance
Toyota provides five complimentary maintenance services for your Prius, to be
performed at the first7,500-mile/6-month maintenance intervals. If you drive
your Prius under special operating conditions (see page 14), you are responsible
for the cost of additional required maintenance.
To obtain your complimentary maintenance services, take your vehicle to an
authorized Toyota dealership. To locate your nearest authorized Toyota dealer-
ship, contact the Toyota Customer Assistance Center at (800) 331-4331 or log on
to www.toyota.com.

Maintenance Records
Maintaining your vehicle according to the recommendations in this booklet is
required to ensure that your warranty coverage remains intact. You should keep
detailed records of vehicle maintenance, including date of service, mileage at
time of service and a description of service and/or parts installation performed.
The scheduled maintenance log in this booklet can help you document this
information. If you sell your vehicle, be sure to give your maintenance records to
the new owner.
Toyota will not deny a warranty claim solely because you do nothave records
to show that you maintained your vehicle. However, damage or failures caused
by lack of proper maintenance are not covered under warranty.
Maintenance Providers
Maintenance and repair services may be performed by you or by any automotive
service provider you choose. Toyota will not deny a warranty claim solely because
you used a service provider other than a Toyota dealership for maintenance and
repairs. However, damage or failures caused by improper maintenance or repairs
are not covered under warranty.
Dealer-Recommended Maintenance
Your dealer may recommend more frequent maintenance intervals or more
maintenance services than those listed in the scheduled maintenance log. These
additional services are not required to maintain your warranty coverage. Ask your
dealer for an explanation of any recommended maintenance not included in the
scheduled maintenance log.
For a complete description of Toyota warranty coverages, see the booklet
entitled
2003 Prius Owner’s Warranty Informationlocated in your vehicle’s
glove box.
