Note that an accurate figure may not be shown in the following cases. "Cruising Range" 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. When refueling, be sure to stop your vehicle and turn the ignition switch off. The actual driving range varies with driving habits and road conditions. If fuel consumption is good, the driving range will be longer. If fuel consumption is poor, the driving range will be shorter. If the low fuel level warning light comes on, refuel even if the display indicates that the vehicle can be driven further. D When the vehicle is stopped with the engine running, the display will indicate the extremely high fuel consumption. D When the vehicle is driving down a long slope, applying the engine brake, the display will indicate the extremely low fuel consumption. "Consumption" The instantaneous fuel consumption is calculated and displayed based on distance and fuel consumption for 1 second with the engine running. The displayed value is updated every 1 second. The calculation is reset when the ignition switch is turned off. "After Refueling" The average fuel consumption is calculated and displayed based on total driving distance and total fuel consumption with the engine running. The displayed value is updated every 10 seconds. Every time you refuel the vehicle, the calculation is reset. When refueling, be sure to stop your vehicle and turn the ignition switch off. cxxiv
