MIRAI_OM_USA_OM62023UThe installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
●
Fuel cell system
● Dynamic radar cruise control system
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the fuel cell vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

WARNING
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. This could lead to an accident, resulting in
death or serious injury.
■When installing the driver’s floor mat
● Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
● Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
● With the fuel cell system stopped and
the shift position in P, fully depress each
pedal to the floor to make sure it does
not interfere with the floor mat.

Immobilizer system
The indicator flashes after the
power switch has been turned off
to indicate that the system is oper-
ating.
The indicator stops flashing after
the power switch has been turned
to ACCESSORY or ON mode to
indicate that the system has been
canceled.
The vehicle’s keys have built-in transponder chips that prevent
the fuel cell system from starting if a key has not been previ-
ously registered in the vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehi-
cle.
This system is designed to help prevent vehicle theft but does
not guarantee absolute security against all vehicle thefts.
