battery TOYOTA MIRAI 2020 Warranties & Maintenance Guides (in English)

SAFETY PRECAUTIONS
Your Mirai Fuel Cell 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 plugs located on top of the high voltage traction
battery and fuel cell stack assemblies.
If an accident occurs, do not touch any high-voltage wiring, connectors or parts, such as the
under hood inverter with converter assembly or the high voltage traction battery assembly.
Do not touch the potassium hydroxide electrolyte that might spill or leak from the high
voltage traction 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.
The hydrogen gas is fl ammable, and can ignite within a large range of concentrations
(4 to 74.5%). However, it diffuses easily and tends not to remain near the ground. If the
sound of hydrogen leaking (a loud hissing sound) can be heard, immediately step away
from the vehicle as there is a chance that the hydrogen gas may ignite.
Water is recommended as the extinguishing agent for vehicle fi res except for hydrogen
and/or high voltage traction battery fi res, which should be allowed to burn out.
The Toyota Mirai Fuel Cell is being offered in limited quantities. While non-powertrain
and non-fuel cell component warranty service can be performed by any Toyota
dealership, powertrain warranty service and fuel cell component warranty service
must only be performed by an authorized Mirai Fuel Cell Toyota dealership.
To locate your nearest authorized Mirai Fuel Cell Toyota dealership, log on to
www.toyota.com or contact the Toyota Customer Experience Center at (800) 331-4331.
