■When towing the vehicle
Be sure to transport the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires contacting the
ground, the drivetrain or related
parts may be damaged, the vehi-
cle may fly off the truck, or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending on the nature of
the damage or malfunction.
