If the fuel cell system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
■ Wheel nut wrench

■ Before transporting or towing in frozen areas
Operate the water release function. Otherwise, the fuel cell sy stem may
freeze and the vehicle may not be able to be started. ( P. 190)

Failure to do so may result in death or serious injury.
■When towing the vehicle
■ 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 damage.
● Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the

Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
Be sure to transport the vehicle with the
front wheels raised or with all four wheels
raised off the ground. If the vehicle is
towed with the front wheels contacting
the ground, the drivetrain and related
parts may be damaged or electricity gen-
erated by the operation of the motor may
cause a fire to occur depending on the
nature of the damage or malfunction.
