Head Impact Protection (HIP)

A package of features designed to lessen the chance of head injury in an accident. Includes energy absorbing materials in the door trims, pillars, roof side-member, roof inner and roof side rails.


Hill-start Assist Control (HAC)

Automatic function that prevents the vehicle rolling downhill when starting off. It is particularly helpful on low-traction surfaces and when driving off road.


Hybrid Synergy Drive (HSD)

The Hybrid Synergy Drive developed by Toyota integrates the desirable elements of a petrol engine and an electric motor. It uses the spontaneous high torque from the electric motor from rest for starting. For cruising in the high-speed range, it utilizes the efficient power of the petrol engine. The management system carefully selects the optimum combination of the petrol engine and electric motor in order to maximise fuel efficiency and reduce emissions.
