Trailers and Towing
Tow Placard Toyota Hilux 3.0 Turbo Diesel
The placard will show the tow-ball down-force rating (or trailer ball load) and towing capacity braked and un-braked. The down-force that is applied by the trailer to the vehicle through the tow-ball, counts toward the vehicles GVM, as do accessories like bull-bars, roll cages, auxiliary batteries, long range fuel tanks, etc.

Towing Safety
The maximum weight of a trailer is specified by its Aggregate Trailer Mass (ATM). The ATM is the combined weight of the trailer and its load. Safety chains are compulsory in Australia and should be attached and shortened to be no longer than necessary. They must be strong enough to hold the trailer and prevent the drawbar from touching the ground in the event the trailer disconnects from the ball. Trailers over 2,500kg must have two safety chains.
All trailers with an ATM over 750kg require brakes, and electronic brake controllers are required to be fitted to vehicles that tow these trailers for the brakes to operate correctly. The control unit is usually fitted within reach of the driver so adjustments can be made to the level of braking applied to the trailer wheels. The control unit sends braking signals to the trailer brakes via the trailer wiring. When adjusted correctly, the tow vehicle and trailer can be slowed as quickly as if the vehicle was stopping by itself.
Electronic Brake Controller
The trailer should be loaded so that the majority of the weight is sitting over the axle(s) and sits as low as possible. Overloading a trailer with too much weight toward the rear will cause the trailer to sway. Overloading a trailer with too much weight toward the front will cause it to oversteer.
Trailer Wiring
