802-1. Fuel cell vehicle
Owners Manual_USA_M62084_en
■High-voltage and high-temperature components
The fuel cell vehicle has high-voltage components (about 650 V
maximum) such as a fuel cell stack, traction battery, power con trol
unit, fuel cell converter, high-voltage cables (which are distinguished
from low-voltage cables by their orange covers), electric motor (trac-
tion motor), etc., and high-temperature parts such as the radiator for
cooling. Pay attention to all w arning labels attached to the vehicle.
This diagram is for illustrative purposes only and may differ f rom the actual
vehicle.

can help reduce excessive
fuel consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing
so will help to reduce the bur-
den on the air conditioning
system and reduce fuel con-
sumption as well.
In winter: Avoid excess heat-
ing. Use the seat heater (if
equipped) or steering heater
(if equipped) to minimize the
need for cabin heating
(P.342).
 Using eco air conditioning
mode, this helps curb fuel
consumption even with the air
conditioning system turned
on. ( P.326, 334)
Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to reduced fuel economy. Install-
ing a large roof rack will also reduce fuel economy.

WARNING
●Make sure to use only standard
sized tires, such as those that
were installed to the vehicle
when it was shipped from the
factory. Otherwise, the
Advanced Park may not operate
properly. Also, when the tires
have been replaced, the dis-
played position of the lines or
box displayed on the screen
may become incorrect. When
replacing the tires, contact your
Toyota dealer.
●As Advanced Park is designed
to assist in parking the vehicle
in a set parking space, depend-
ing on the condition of the road
surface or the vehicle, the dis-
tance between the vehicle and a
parking space, etc., it may not
be possible to detect a parking
space or may not be able to pro-
vide assistance to the point the
vehicle is fully parked.
●In situations such as the follow-
ing, it may not be possible for
the Advanced Park to provide
assistance to the selected park-
ing spot:
• When the tires are extremely worn or the tire inflation pres-
sure is low
• When carrying a heavy load
• When the vehicle is tilted due to the carried load
• When a heater is installed in the surface of the parking space
(road surface freeze prevention
heater)
• When the wheels are mis- aligned, such after a wheels has
been subjected to a strong
impact
If the vehicle deviates greatly from
the set parking space in any situa-
tion other than the above, have
the vehicle inspected by your Toy-
ota dealer.
