2019 TOYOTA PRIUS battery

SAFETY PRECAUTIONS
Your 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 or replace 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 result of 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.
Toyota recommends having maintenance and repairs for your Prius performed
by an authorized Toyota dealership. To locate your nearest authorized Toyota
dealership, contact the Toyota Customer Experience Center at (800) 331-4331
or log on to www.toyota.com.
