Your vehicleEquipment or remote type

Help identify your model and equipment

What is excluded?

Other model years or markets, Axela / diesel and aftermarket equipment with a different procedure.
4-Door sedan trunk lights use a different 3 W lamp and access method and are outside this plan. Aftermarket LEDs, unknown lamp units, damaged wiring, trim removal beyond the lamp lens and fuse / circuit work are excluded.

2 Prepare

You can save preparation while your vehicle or equipment is still unconfirmed.

Park away from traffic, set the parking brake and keep the ignition off unless a final parked functional observation explicitly requires the normal controls.Is this the original 2017 US Mazda3 5-Door luggage-compartment lamp with the OFF / ON switch shown on printed page 5–112, a confirmed matching 5 W bulb and safe access to its lens?Manual illustrations on printed pages 5–112 and 6–58/59Small flathead screwdriver wrapped with a soft clothOriginal-equipment-compatible 5 W bulb confirmed for the actual hatchback luggage lamp; the specification table gives no UNECE category or universal part numberSoft cloth for protecting the lens

With the lamp fully refitted and liftgate safely open, check both ON illumination and OFF response. An unchecked control, remaining outage or insecure lens leaves the work incomplete or requiring inspection.

3 Follow the steps

Confirm compatibility and choose the readiness branch before recording steps.

Confirm the 5-Door luggage-compartment light and the switch shown on printed page 5–112. With the ignition off and liftgate safely open, set this lamp switch to OFF before handling the lens. ON lights it when the liftgate is open; ignition OFF does not by itself turn this lamp off. Let any recently lit bulb cool before handling it. Stop if the switch or unit differs.Manual reference · PDF 405; printed 5–112
Confirm a replacement that matches the actual original bulb and its 5 W rating. The separate 4-Door trunk light is 3 W and uses a different removal method; do not substitute its specification. Since the table leaves the UNECE category blank, confirm the physical bulb / base match rather than guessing a universal code or size.Manual reference · PDF 593; printed 9–10
Keep the screwdriver away from interior electrical terminals because contact can cause a short circuit. Use the tool only at the illustrated lens edge. Mazda recommends dealer help for bulb replacement; do not probe a terminal, bypass the switch or extend this task to wiring.Manual reference · PDF 458; printed 6–45
Wrap the small flathead screwdriver with a soft cloth. Carefully release the lens at the edge illustrated for the 5-Door luggage lamp on printed page 6–58. Stop if the lens is stuck, cracks or does not match the illustration; keep other trim in place.Manual reference · PDF 471; printed 6–58
Following printed page 6–59, press the connector tab with a finger and pull the connector from the lamp unit; pull on the connector body, not the wires. Then remove the bulb by pulling it out as illustrated. Stop for a damaged connector or one that will not release normally.Manual reference · PDF 472; printed 6–59
Install the confirmed 5 W replacement and refit in the reverse order of removal. Restore the connector and lens, making sure both are securely seated and no wiring is caught. Keep the lamp switch OFF until reassembly is complete.Manual reference · PDF 472; printed 6–59
For the result record, with the lens fully installed and liftgate still safely open, set the luggage-light switch to ON and check illumination; then select OFF and check that it goes out. Record both results and leave the desired normal setting. A lamp that stays out, flickers or will not switch normally needs inspection, without fuse or wiring work in this task.Manual reference · PDF 405; printed 5–112

4 Check the result

Matched 5 W bulb fitted, connector and lens secure, and the lamp responds normally to OFF / ON with the liftgate open
With the lamp fully refitted and liftgate safely open, check both ON illumination and OFF response. An unchecked control, remaining outage or insecure lens leaves the work incomplete or requiring inspection.
Preserve any unresolved defect and its next action; a completed web record does not certify a repair.

Select what you actually observed. If you have only prepared the plan, record that instead.

Stop and get help if

An unknown unit or replacement, a lamp that cannot be kept OFF, a stuck / cracked lens, a connector that will not release, exposed or heat-damaged wiring, insecure refitting or a remaining outage
Stop for an unmatched unit or bulb, a switch that will not keep the lamp off, damaged / stuck lens or connector, exposed wiring or heat damage. If normal operation is not restored after correct refitting, ask Mazda or a suitable repairer to inspect it without moving into wiring or fuse diagnosis.
Stop if the actual part, attachment or surface differs from the matched manual.
