BASIC HYBRID VEHICLE OPERATION Hybrid Synergy Drive System The Hybrid Synergy Drive System utilizes a computer controlled gasoline engine and electric motor to provide the most efficient combination of power for the vehicle. To conserve energy, when the brakes are applied, braking force generates electricity which is then sent to the traction battery. In addition, the engine shuts off when the vehicle is stopped. The benefits are better fuel economy, reduced vehicle emissions and improved performance. Note: Fuel consumption and energy information of the Hybrid System are shown on the multi-information display. Refer to this screen for important driving information and feedback to maximize energy use/creation and conserve fuel. Tips for improved fuel economy -Ensure tire pressures are maintained at levels specified in the Owner's Manual. -If possible, link trips to reduce engine cold starts. -Avoid driving at speeds that are higher than necessary, especially on the highway. -When possible, avoid sudden stops to maximize regenerative braking energy. -Minimize use of the Air Conditioning. Refer to the Owner's Manual for more details. 2
