M62048U(19MY)The installation of a mobile two-way radio system in your vehic
le could affect
electronic systems such as:
● Fuel cell system
● Anti-lock brake system

● Seat belt pretensioner system
● Toyota Safety Sense 2.0
Be sure to check with your Toyota dealer for precautionary meas ures or spe-
cial instructions regarding instal lation of a mobile two-way radio system.
High voltage parts and cables on the fuel cell vehicles emit ap proximately the
same amount of electromagnetic waves as the conventional gasoli ne pow-
ered vehicles or home electronic appliances despite of their el ectromagnetic
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 acc ident, resulting in
death or serious injury.
■ When installing the driver’s floor mat
● Do not use floor mats designed for other models or different mo del 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

the fuel cell system from starting if a key has not been previ-
ously registered in the veh icle’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.

The electric motor (traction motor) allows smooth, powerful takeoff
and acceleration. This vehicle dr ives similarly to a gasoline vehicle
without any special actions by the driver. ( P. 172) As there are no
engine sounds and the vehicle is q uiet, operation noises unique to
fuel cell vehicle com ponents may be heard. ( P. 8 8 )
The system may behave differently on cold days. It is performin g a
special cold-start process to im prove start-up performance. (P. 189)
Operation noises ( P. 88), purge process ( P. 189), etc., differ from
usual. However, this is not a malfunction.
