■High-voltage and high-temperature components
The fuel cell electric vehicle has high-voltage components (abo ut
650 V maximum) such as a fuel c ell stack, traction battery, power
control unit, fuel cell converter, high-voltage cables (which a re distin-
guished from low-voltage cables b y their orange covers), electric
motor (traction motor), etc., and high-temperature parts such a s the
radiator for cooling. Pay attention to all warning 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.351).
 Using eco air conditioning
mode, this helps curb fuel
consumption even with the air
conditioning system turned
on. ( P.334, 341)
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.
