■While towing
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
■ Wheel nut wrench
Wheel nut wrench is installed in luggage compartment. ( P. 5 9 8 )
■ Towing eyelet installation hole on the rear of the vehicle
The hole is equipped for fastening the
vehicle while shipping. The towing eyelet
installed in this hole cannot be used for
towing another vehicle.
WARNING
Observe the following precautions.
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 eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple, 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
parking lock.
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.
