General

Power Steering System

Full hydraulic steering system is adopted as the standard as on the previous models.
The power steering system on the previous models has used an exclusive motor pump to supply hydraulic
oil to the power steering system.
On the new models, the hydraulic oil from the oil pump is shunted by the priority valve to supply hydraulic
oil at an appropriate pressure to each power system.

Solenoid valve

Priority valve

Oil control valve

Steering valve

Oil pump

Oil tank

Rear axle

Rear axle cylinder
