TIPS FOR IMPROVED FUEL ECONOMY
DEFAULT SETTING
CUSTOMIZED SETTING
STARTING YOUR VEHICLE
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 
and reduced vehicle emissions.
NOTE: Fuel consumption and energy information of the Hybrid System are 
shown on the Audio Multimedia System screen or the navigation system (if 
equipped).
1. Ensure tire pressures are maintained at levels specified in the Owner’s Manual.
2. When possible, link trips to reduce engine cold starts. 
3. Avoid driving at speeds that are higher than necessary, especially on the highway.
4. When possible, avoid sudden stops to maximize regenerative braking energy.
5. Minimize use of the air conditioning.
