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