■Power outlet
●The power outlet is a device in
order to use electronic devices
within the vehicle.
●While a power outlet is being
used, a cooling fan sound may be
heard from near a rear seat. This
does not indicate a malfunction.
■Devices which may not operate
correctly
The following 120 VAC devices may
not operate properly even if their
power consumption is less than
1500 W:
●Devices with high initial peak watt-
age
●Measuring devices that process
precise data
●Devices that require an extremely
stable power supply
●Devices that require a constant
power supply from the power out-
let, such as a device with a timer.
■When the power supply func-
tion cannot be used
If the AC120V switch is pressed but
the switch indicator does not illumi-
nate, the protection circuit may have
operated. In this case, perform the appropriate
procedures as follows.
●Disconnect the plug of each
device from the power outlets,
check that the total power con-
sumption of all de
vices to be con-
nected to the power outlets is less
than 1500 W, reconnect the
devices and then press the
AC120V switch again.
●Disconnect the plug of each
device from the power outlets,
check that the devices are not
malfunctioning, reconnect the
devices and then press the
AC120V switch again.
●Check the charge of the traction
battery ( P.119). If the charge is
low, shift the shift position to P,
allow the fuel cell system to oper-
ate to charge the traction battery,
and then press the AC120V
switch again.
●If the temperature inside the vehi-
cle is high, such as after the vehi-
cle has been parked under the
sun, move the vehicle to a shaded
area, use the air conditioning sys-
tem to sufficiently cool the interior,
and then press the AC120V
switch again.
●When it is particularly cold, the
power outlets may not be able to

the radar sensor which is
equipped behind the emblem.
Otherwise it may cause the
device to be damaged.
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Fuel cell stack
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, s uch as moldings
and bumpers, may be deformed
and damaged.
Also, do not continuously hold the
nozzle in the same place.
●Do not spray the lower part of
the windshield continuously.
