Instantaneous fuel consumption ("INST MPG" or "INST L/100 km") The instantaneous fuel consumption is calculated and displayed based on distance and fuel consumption at 20 revolutions of the engine. The displayed value is updated for a short time. An accurate figure may not be shown if the vehicle is driving down a long slope, and engine brake is applied. (The display will indicate the extremely low fuel consumption.) When the vehicle is stopped with the engine running MPG" will be shown on the display. The calculation is reset when the engine switch is turned off. 4. Driving range "RANGE km") ("RANGE MI" or The distance the vehicle can travel with the remaining fuel is calculated and displayed based on the quantity of remaining fuel and past fuel consumption. The driving range display indicates the approximate distance that you can drive until the fuel gauge reaches "E". It is different from the actual distance traveled. The displayed value is updated every time the fuel equivalent for 1 mile or 1 km is consumed. Every time you refuel the vehicle, the calculation is reset. The actual driving range varies with driving habits and road conditions. If fuel efficiency is good, the driving range will be longer than indicated. If fuel efficiency is poor, the driving range will be shorter than indicated. If the low fuel level warning light comes on, refuel the vehicle even if the display indicates that the vehicle can be driven further.
