Action Steps to Boost MPG
-
Switch to Eco mode: Press the drive mode button on your dash until Eco lights up. It tweaks throttle and transmission for fuel savings. Use it on daily drives and highways.
-
Check tires weekly: Inflate to 36 PSI cold. See the door sticker for exact specs. Low pressure kills MPG. Right pressure lets you go farther per tank.
-
Drive smooth: Accelerate and brake gently. Hold 55 to 65 MPH. Set cruise control on roads like I-76. Adaptive cruise keeps speeds steady for max savings.
-
Cut idles and weight: Shut off the engine after 1 minute stopped. Remove heavy cargo. Every 100 pounds drops 1-2 MPG.
-
Maintain filters and oil: Swap the air filter every 15,000 miles for 1-3 MPG gain. Stick to 0W-20 oil. Service every 7,500 miles.
-
Ease AC use: Set to 73 degrees in auto mode. Full cold costs 1 MPG. Use route apps to dodge Chester County traffic.
