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.

IF YOU NEED ASSISTANCE
oth Toyota and your Toyota dealer
are dedicated to serving your
automotive needs. Your complete
satisfaction is our ﬁrst priority. Should
you have a problem or concern — either
during or after the warranty period —
please take the following steps to ensure
the quickest possible response:
Discuss the situation with a dealership
manager, such as the service manager
or customer relations manager. In most
cases, a satisfactory solution can be
reached at this step.
If the dealership does not address your
concern to your satisfaction, call the
Toyota Customer Experience Center
at (800) 331-4331.
Please have the following information
ready when you call:
• Your Toyota’s vehicle identification number
(located on the driver’s side corner of the
dashboard, under the windshield)
• Current mileage on your vehicle
• Name of your Toyota dealership
A Toyota customer relations representative
will assist you in working with the dealership
to ﬁnd a satisfactory solution.
If your concern has still not been resolved
to your satisfaction, Toyota offers
additional assistance through the Dispute
Settlement Program, a dispute resolution
program administered by the National
Center for Dispute Settlement. The
purpose of the Dispute Settlement
Program is to resolve disputes through
arbitration — a process by which two
parties authorize an independent third
party to hear and resolve a dispute. The
program is informal and free of charge.
To request that your case be reviewed
through the program, complete the
customer claim form in the
Warranty Rights Notification
(found in your glove box) and mail it to:
National Center for Dispute Settlement
P.O. Box 688
Mt. Clemens, MI 48046
To initiate arbitration, you must complete
an NCDS customer claim form and mail it
to NCDS. To request a form, call NCDS
at (800) 777-8119 or obtain a copy at
www.ncdsusa.org. When you call,
please have your vehicle identiﬁcation

THE IMMOBILIZER KEY
THE NEW WORLD OF
This Toyota vehicle may be equipped
with an electronic “immobilizer” anti-theft
system. When the key is inserted into the
ignition switch it transmits an electronic
code to an immobilizer computer. The
engine will only start if the code in the
key matches the code in the immobilizer.
If the code does not match, the immobilizer
disables the ignition and fuel systems.
While an exact physical copy of the key
will open the door and allow retrieval of
items locked in the vehicle, it won’t start
the vehicle unless the key has the same
code as the immobilizer.
For security purposes, access to key
codes and service procedures for
electronically registering replacement
keys is restricted. Only a Toyota dealer
or certain bonded/registered independent
locksmiths can generate replacement keys.
Page 10 of 52
REPLACING THE KEY
Upon purchase, each vehicle should have
two master keys and an aluminum tag
with a key-code imprinted on it.
To generate a fully functional replacement
key (one that will both open the doors and
start the engine), one of the master keys
is required. To make a key that will open
the door for retrieval of items locked
inside the vehicle, the aluminum key-code
tag can be used. If a master key or the
aluminum key-code tag is not available,
a Toyota dealer or certain registered
locksmiths can obtain the key code from
a restricted-access database. These
businesses can also access a service
utility to reprogram the immobilizer if
all registered master keys have been
lost. If a Toyota dealer is not available,
please refer to www.aloa.org to ﬁnd
a bonded/registered locksmith who
performs high-security key service.
KEEPING THE KEY SAFE
Replacing an immobilizer key may be
costly. It is advisable to keep a spare
master key and the aluminum key-code
tag in a safe place. If you record the
key-code in more than one place, do not
record it in a way that can be easily
identiﬁed and associated with the vehicle.
It is wise to keep a copy of the key-code
outside of the vehicle.
If the vehicle was delivered with less than
two keys and the aluminum key-code tag,
consider having the Toyota dealer or a
qualiﬁed independent automotive locksmith
make a duplicate key before you need it.
