• Compressed air source
Washer fluid
( P.412)
• Water or washer
fluid containing
antifreeze (for
winter use)
• Funnel (used only for adding
water or washer
fluid)
WARNING
The fuel cell unit compartment
contains many mechanisms and
fluids that may move suddenly,
become hot, or become electri-
cally energized. To avoid death or
serious injury, observe the follow-
ing precautions.
■When working on the fuel cell
unit compartment
●Be careful not to touch the high-
voltage parts or hydrogen-
related parts.
●Make sure that the “READY”
indicator is off.
●Keep hands, clothing and tools
away from the moving fan.
●Be careful not to touch the
motor, inverter, radiator, etc.
right after driving as they may
be hot. Coolant and other fluids
may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the fuel cell unit com-
partment.
ItemsParts and tools●Do not smoke, cause sparks or
expose an open flame to the 12-
volt battery. 12-volt battery
fumes are flammable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid
can harm your hands or eyes
and damage painted surfaces. If
fluid gets on your hands or in
your eyes, flush the affected
area with clean water immedi-
ately.
If you still experience discom-
fort, consult a doctor.
●Never touch, disassemble,
remove or replace the high-volt-
age parts, cables and their con-
nectors. It can cause severe
burns or electric shock that may
result in death or serious injury.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is off.
With the power switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P. 4 1 1 )
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
motor wear due to dirt in the air.
