Towing
A
B D
C
If the vehicle needs to be towed, call a professional
towing service. Never tow the vehicle behind another
vehicle with a rope or chain. It is very dangerous.
There are three popular methods of towing a vehicle.
The operator loads the vehicle
on the back of a truck.
To accommodate flat-bed equipment, the vehicle is
equipped with front towing hooks (A), front tie down
hook slots (B), rear towing hook (C), and rear tie down
hook slots (D).
The rear towing hook can be used with a winch to pull
the vehicle onto the truck, and the tie down hook slots
can be used to secure the vehicle to the truck.
