Step by step.
- 01
Confirm that vehicle power is switched OFF.
- 02
Press Unlock on the registered key while approaching the parked Mazda3.
- 03
Confirm that the headlights, parking lights, taillights, side-marker lights and license-plate lights illuminate.
- 04
Enter the vehicle, or allow the lights to turn off automatically after 30 seconds.
- 05
To cancel early, set the light switch to OFF or press Lock on the key.
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.
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.
