Safety Precautions
Your Toyota Highlander 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 on the left-hand side of the rear seat base.
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 a result of the 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 .
KEEP IT GENUINE

built with — Genuine Toyota Parts!
