SAFETY PRECAUTIONS The RX 450h is a gas/electric hybrid vehicle that 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 unless appropriate precautions are taken. To avoid personal injury, please follow all caution labels attached to highvoltage parts. Do not touch or attempt to remove or replace any high-voltage (orange-colored) wiring and connectors. Do not touch the service plug behind the trim under the left rear seat. If an accident occurs, do not touch any high-voltage wiring, connectors or parts such as the inverter under the hood or the hybrid battery assembly under the rear seat. Do not touch the potassium hydroxide electrolyte that might spill or leak from the hybrid 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.
