If the key is removed from the ignition switch or placed in the ACC position or the LOCK/OFF position with the headlights ON, the headlights (and/or parking lights) remain on for about 5 minutes. However, if the driver’s door is opened and closed, the headlights are turned off after 15 seconds.
The headlights can be turned off by pressing the LOCK button on the remote key or smart key twice or turning the light switch to the OFF or AUTO position. However, if you turn the light switch to the AUTO position when it is dark outside, the headlights will not be turned off.
CAUTION
If the driver gets out of the vehicle through other doors (except the driver’s door), the battery saver function does not operate and the headlight escort function does not turn off automatically. Therefore, it causes the battery to be discharged. In this case, make sure to turn off the lamp before getting out of the vehicle.
