Tips to get better MPG from your Yaris
Accelerate briskly to your cruising speed, then lift off and tap the throttle to force the car into EV (electric) mode.
Use 'B' mode (engine braking) only on steep descents; using it on flat roads reduces coasting efficiency.
Maximize time in Eco mode; it smooths out throttle responses and optimizes climate control efficiency.
