Owners Manual_USA_M62064_ennot flat.
*: Depending on the weather, sea-
son, usage environment, etc., the
vehicle compartment may
undergo extreme high or low tem-
peratures.
■When using while the vehicle is
parked or stopped
●The door cannot be locked or
unlocked with the electronic key.
The door can be locked/unlocked
only with the mechanical key
( P.126).
●When the surroundings become
dark while power is being sup-
plied, the headlig hts will automati-
cally turn on.
Turn off the light ( P.198)
■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
be used, to prote ct the traction
battery. In that c ase, drive the
vehicle and use the power outlets
after the traction battery has
warmed up.
●When the fuel door is open, close
the door and press the AC120V
switch again.
If the power outlets cannot be used
even after performing the appropri-
ate procedures above, have the
vehicle inspected by your Toyota
dealer.
●If any electrical device has mal-
functioned, park the vehicle in a
safe location and turn the AC
inverter off.
