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 accord ance with the messages displayed on the
driver information interface.
• Use the recommended vi scosity engine oil.
2Recommended Engine Oil P. 488
•Maintain the specified tire pressure.
• Do not load the vehicle 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

Maintenance
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior.
• Do not spray water into the engine compartment.
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, coolant, or batter y fluid on resin coated parts, they may be
stained or the coating may peel. Promptly wipe it away using a soft cloth and clean
water.
Wipe using a glass cleaner.

you want to repair the pa inted surface of the parts
made of resin.
1 Cleaning the Window
When you raise a wiper arm, you may inadvertently
alter the position of the arm by applying undue force.
If you notice that an arm is not in its proper return
position, active the wipers once and they will
automatically reset. 2 Wipers and Washers P. 168
