2021 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.

1 Inspect sealed transmissions, transfer cases and differentials for signs of leakage. If any leakage from a sealed component is suspected, it is recommended that you have the sealed component inspected by a Toyota dealer. Inspect power steering fluid (if equipped) and brake fluid level/condition. Inspect engine and inverter (if equipped) coolant level/condition/freezing point. Your dealer may recommend services (Dealer-Recommended Maintenance) based on inspection results.2 Reset the oil replacement reminder light (“MAINT REQD”) or the message “OIL MAINTENANCE REQUIRED” on the multi-information display after maintenance at every 5,000 miles.3 Perform these service items only if you drive primarily under the conditions indicated.4 Refer to “Engine/Inverter Coolant” in the “Explanation of Maintenance Items” section in the back of this guide for more information.5 Visually check the HV battery cooling intake filter for dirt or dust every 5,000 miles and clean if necessary. Clean every 20,000 miles.6 Not all vehicles are designed for towing. Refer to your Vehicle Owner’s Manual for details.
NOTE: Driving in heavy traffic, on dirt roads or in urban, dusty or desert areas may shorten the life of the cabin air filter. Replacement may be needed if you notice reduced airflow from the air conditioner and heater or if the windows fog easily when you use the Fresh mode. Consult your dealer if any of these conditions occur.
