FEATURES/OPERATIONS 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 the 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. Tips for improved fuel economy -Ensure tire pressures are maintained at levels specified in the Owner's Manual. -When 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.
