Why are the interior lights not turning off in my Toyota Highlander?

Possible Causes for Interior Lights Not Turning Off in a Toyota Highlander
There can be several reasons why the interior lights in a Toyota Highlander may not turn off. Let’s explore some possible causes based on the search results:
1. Issue with the Light Icon Button: In some Toyota Highlanders, there is a light icon button that controls the interior lights. Pressing this button can fix the problem and turn off the lights.
2. Dome Light or Dimmer Switch: The most common cause of interior lights not turning off is when someone other than the driver uses the dome light or dimmer switch. This can leave the lights in a state where they no longer come on when the door is opened. Rotating the dimmer switch or trying different positions may help resolve the issue.
3. Smart Key System: In Toyota Highlanders with a smart key system, the interior lights automatically turn on/off according to the engine switch position, whether the doors are locked/unlocked, and whether the doors are open/closed. If the lights remain on when the engine switch is turned off, they will go off automatically after 20 minutes.
4. Optional Preference: Some Toyota Highlanders have an optional preference to have the lights come on when the doors are open, with or without pressing the “door” button. This feature can be activated through a scan code.
5. Electrical Issue: In rare cases, there may be an electrical issue causing the interior lights to stay on. If none of the above solutions work, it is recommended to consult a professional or contact a Toyota dealership for further assistance.
Please note that these are general suggestions based on the search results, and it is always best to consult the owner’s manual or seek professional help for specific troubleshooting steps.
