2018 TOYOTA AVALON HYBRID battery

SAFETY PRECAUTIONS
Your Avalon Hybrid 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 f re occurs, extinguish it with a Class D powder-type f re extinguisher.
Toyota recommends having maintenance and repairs for your Avalon Hybrid
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.

MAINTENANCE
You are responsible for performance of
the required maintenance indicated in the

lack of maintenance is not covered by this
warranty.

failure or noncompliance caused by
improper maintenance or repairs is not
covered by this warranty.
