Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2
Emissions
Achieving fuel economy and reducing CO2 emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accord ance with the messages displayed on the
multi-information display.
• Use engine oil with the viscosity recommended.
2 Recommended Engine Oil P. 499
•Maintain the specified tire pressure.
• Do not load the vehicl e with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more
information on how this test is performed, please visit
https://www.nrcan.gc.ca and search for “fuel
consumption testing” in the search field at the top of
the page.

the engine may fail or be damaged.
This seal indicates the oil is energy conserving
and that it meets the American Petroleum
Institute’s latest requirements.
Use Honda Genuine Motor Oil or another
commercial engine oil of suitable viscosity for
the ambient temperature as shown.
■Synthetic oil
