When adjusting, you need to observe the vehicle's dashboard, which will display the instantaneous fuel consumption and fuel consumption per 100 kilometers. The data is for reference only. There are control buttons on both the left and right sides of the display screen, which can switch display items, showing instantaneous fuel consumption and average fuel consumption. The relationship between vehicle weight and fuel consumption is directly proportional. It is said that for every 10% reduction in vehicle weight, fuel consumption will also decrease by a certain percentage.

The most convenient fuel consumption display for the Corolla is right on the instrument panel, visible on the multi-function display. There are usually three buttons on the right side of the steering wheel, and the middle one labeled 'DISP' is the toggle button. Press it a few times to cycle through various fuel consumption data. I often check this because it clearly shows recent changes in driving fuel efficiency—numbers spike during city traffic jams but drop on highways. Besides the current instant fuel consumption, it also displays average fuel consumption after startup and after a single refuel, which is perfect for someone like me who enjoys tracking vehicle costs. Occasionally, a small leaf icon appears in the lower right corner of the instrument panel, indicating eco-driving tips, which are also related to fuel efficiency.

From a technical perspective, the central trip computer display on the Corolla's instrument cluster serves as the core area for monitoring fuel consumption. By using the control buttons on the right side of the steering wheel to toggle through display items, common readings include 'AVG' (average fuel consumption), 'KM/L' (kilometers per liter), and instant fuel consumption indicators. Personally, I've noticed slight differences in button layouts between the 9th and 12th generation Corollas, with the 12th generation's up/down arrows being more intuitive. Interestingly, when ECO mode is activated, the system displays real-time power output ratios through blue backlighting, which indirectly affects fuel economy. If the data hasn't been reset for an extended period, it reflects long-term driving habits. A quick 1-second press of the DISP button resets the trip data for recalculation.

When I first got the car, I couldn't find the fuel consumption display either. Later, I discovered it's actually very simple: After starting the car, look at the steering wheel. There's a button with a square pattern on the right side (the DISP button). Each press switches the dashboard to a different data page. The small square area below the fuel gauge will alternately display 'distance to next refueling in km', 'current speed', and most importantly, the 'AVG fuel consumption'. I've made it a habit to switch to the fuel consumption page as soon as I get in the car. Recently, I've been quite satisfied with 7.2L/100km. Remember, real-time data only appears after you start moving – the readings aren't accurate when idling in place.
