Doing so interferes with the sensor detecting the level of ambient light and may cause the automatic headlight system malfunction. n Automatic light off system When driving The headlights turn off automatically, if the engine is stopped and the driver's door is opened while the headlights are turned on. To turn the headlights on again, turn the key to ON, or turn the light switch off once and then back to or position. n Automatic headlight leveling system The level of the headlights is automatically adjusted according to the number of passengers and the loading condition of the vehicle, to ensure that the headlights do not interfere other road users. n Customization The time takes for headlights to automatically turn on or off can be changed. 97
