Driving
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 accordance with the messages displayed on the 
driver information interface.
• Use the recommended viscosity engine oil.
2 Recommended Engine Oil P. 484
•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
