Impact on distance to empty

The vehicle displays the distance to empty differently according to the drive mode selected in the drive mode integrated control system.

For more information, see the list below.

  • Driving range depends on your driving style, the vehicle’s electrical load usage, the environment, and the high voltage battery charge level. These effects might cause the distance to empty displayed on the vehicle to be higher or lower than the certification range.

  • Driving style refers to your driving speed and your acceleration and deceleration tendencies. The higher the speed, or the more frequently you accelerate and decelerate, the more the distance to empty decreases.

  • Electrical loads usage means air conditioning, heaters, lamps or additional auxillary loads, and as the usage increases, distance to empty will be reduced.

  • Environment refers to weather, temperature, and terrain. The distance to empty decreases in cases of snow, rain, high winds, low temperatures, and uphill, slippery, or rough road surfaces.

  • High voltage battery energy is proportional to SOC (charge amount), but might vary depending on the battery temperature, SOH (battery health), and so on.

Change of distance to empty when 100% charging

  • If the distance to empty decreases while the vehicle learns your driving style or due to the environment in which you use the vehicle, the driving distance might increase again if you drive according to the Good driving practices. You can have the distance to empty reset at a workshop, but this does not actually increase the range. Therefore, the distance to empty might be inaccurate until the vehicle learns your driving style.

  • Distance to empty decreases when the high voltage battery temperature is low in winter. This is not a permanent change. If the temperature rises, the distance to empty increases again.

  • Reducing the use of electrical loads increases the available range.

  • The longer you use the vehicle, the more the high voltage battery naturally degrades, which reduces the distance to empty.

Operating tips to improve driving range

  • As electric vehicles speed up, air resistance increases rapidly, so not speeding helps increase your driving range.

  • Rapid acceleration consumes significant driving energy. Rapid deceleration restricts motor regenerative braking. Keep your speed and the engagement of the accelerator pedal constant.

  • Excessively operating the heater and air conditioner can increase power consumption and shorten the driving range. Setting the temperature to 72°F (22°C) AUTO leads to optimal energy consumption while driving. Using a heated seat and reducing air heating in winter is very helpful. Turn off the heater and air conditioner when you do not need to heat or cool the vehicle.

  • Selecting recirculation mode consumes less energy than selecting fresh mode. Fresh mode consumes significant energy because the vehicle must reheat or cool air from outside. Driving with the window open increases air resistance and heater and air conditioner use. To reduce energy consumption, close the window completely while driving.

  • When driving alone, use DRIVER ONLY mode for the heater and air conditioner.

  • Always maintain the specified tire pressure and use tires made specifically for electric vehicles.

  • Do not use unnecessary electrical components while driving.

  • Do not load unnecessary items in the vehicle.

  • Do not mount parts that might increase air resistance.
