While towing

●

When towing using an elastic towing rope, avoid sudden starts, etc. which place

excessive stress on the towing hooks, the elastic towing rope. The towing hooks, the

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 vehicle may fly off the truck.
