Designed to boost low-speed traction for improved starts, docking and slippery road conditions, ET grips the road to help save fuel.
OT balances the weight between the two rear axles when loaded. If wheel slip is detected, it temporarily increases load to the drive axle for improved traction.
BT lowers the lift axle regardless to help maintain a 50/50 load split between axles during loading or unloading, prolonged stops or other areas that require 50/50 splits.
