tery produces hydrogen gas which
is flammable and explosive. There-
fore, observe the following precau-
tions before recharging:
●If recharging with the 12-volt bat-
tery installed on the vehicle, be
sure to disconnect the ground
cable.
●Make sure the charger is off when
connecting and disconnecting the
charger cables to the 12-volt bat-
tery.
■After recharging/reconnecting
the 12-volt battery
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the 12-volt battery. If this
happens, use the wireless remote
control or the mechanical key to
lock/unlock the doors.
●Start the fuel cell system with the
power switch in ACC. The fuel cell
system may not start with the
power switch turned off. However,
the fuel cell system will operate

If your vehicle needs
to be towed
If towing is necessary, we
recommend having your
vehicle towed by your Toy-
ota dealer or commercial
towing service, using a
wheel-lift type truck or flat-
bed truck.
Use a safety chain system
for all towing, and abide by
all state/provincial and local
laws.
WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When towing the vehicle
Be sure to transp ort the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires co ntacting the
ground, the drivetrain and related
parts may be damaged, an acci-
dent may occur due to a change
in direction of the vehicle or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending o n the nature of
the damage or malfunction.
■While towing
●When towing using cables or
chains, avoid sudden starts, etc.
which place excessive stress on
the towing eyelets, cables or
chains. The towing eyelets,
cables or chains may become
damaged, broken debris may hit
people, and cause serious dam-
age.
●Do not perform any of the fol-
lowing as doing so may cause
the parking lock mechanism to
engage, locking the rear wheels
and possibly leading to an acci-
dent resulting in death or seri-
ous injury:
• Unfasten the driv er’s seat belt
and open the driver’s door.
