Important limits

  • If the function has been disabled in Mazda Connect, pressing Unlock will not invoke the lighting sequence.
  • The lights time out after 30 seconds unless one of the documented early-cancel actions occurs.
  • Leaving Home Light is separate from Coming Home Light, which is activated from inside after power is switched to ACC or OFF.
If it does not work

Quick checks.

  • ✓If the doors unlock but the lights stay off, check the Leaving Home Light setting in Mazda Connect.
  • ✓Confirm vehicle power is OFF before retrying.
  • ✓If only one exterior lamp is missing, inspect that lamp rather than repeating the key sequence.
