SPORT HYBRID i-MMD (intelligent Multi-Mode
Drive)
Your SPORT HYBRID i-MMD vehicle uses both an electric motor and a gasoline engine as propulsion sources, with the electric motor
receiving electricity from an internal High Voltage battery or internal generator. The High Voltage battery is charged from the generator
driven by the engine or regenerative braking.
When driving, your vehicle is propelled exclusively by the electric motor, exclusively by the gasoline engine, or by a combination of the two.
The system selects which propulsion source is most appropriate and automatically switches to it. Under certain circumstances, pressing the
EV button can manually enable EV (driven only on electricity) mode.
● Energy efficiency
As with a gasoline-powered vehicle, hybrid vehicle fuel efficiency and driving range is most impacted by your driving style. Aggressive
acceleration and high-speed driving can easily trigger the system to switch the propulsion source to the gasoline-powered engine.
In addition, heavy climate control system use negatively affects vehicle range and efficiency. Either of these use patterns will more quickly
reduce the High Voltage battery's state of charge.
● Battery types
There are two types of batteries used in this vehicle; a standard 12-volt battery that powers the airbags, the interior and exterior lights, and
other standard 12-volt systems; and a high voltage battery that is used to power the propulsion motor and recharge the 12-volt battery.
