Help identify your model and equipment

What is excluded?

Other model years or markets, Axela / diesel and aftermarket equipment with a different procedure.
Vanity-mirror lights, cargo / trunk lights, aftermarket LED conversions, integrated LED units, unknown fittings, roof-console removal, headliner work, airbag-area work and electrical fault finding 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 the failed original overhead / map fixture matched to the manual illustration and its 8 W or 10 W rating, with the overhead switch at OFF, any individually switched map light off and safe access to the lens only?The exact matching fixture illustration on printed pages 6–57/58Small flathead screwdriver wrapped with a soft clothA stable position that reaches the lens without pulling roof trimOriginal-equipment-compatible replacement bulb matched to the actual fixture: front overhead/map assembly 8 W; separate front overhead fixture 10 W; rear overhead fixture 10 WSoft cloth for protecting the lens

YOUR OBSERVATIONS

Keep the before and after.

Only on this device

Record the exact fixture and lamp position, correct 8 W or 10 W rating, confirmed bulb fit, OFF controls and secure lens retention. Keep a real parked switch result separate from merely installing a new bulb.

Before the checkAfter the check

After full lens refitting, operate only the affected lamp with its normal control while parked. A missing check stays incomplete; a remaining outage, damaged fitting or unsecured overhead lens needs inspection.

3 Follow the steps

Confirm compatibility and choose the readiness branch before recording steps.

Identify one affected fixture and match its actual shape to the manual. The front overhead/map-light assembly uses 8 W bulbs; the separate front overhead fixture uses 10 W; the rear overhead fixture uses 10 W. The table supplies no UNECE bulb category for these rows, so confirm the actual base and bulb fit with Mazda or a correct vehicle-specific listing before removal. Do not assume equal-looking bulbs have the same rating.Manual reference · PDF 593; printed 9–10
Park and turn the ignition off as a preparation precaution. Put the overhead-light switch at OFF, rather than DOOR or ON. With map lights, the lenses are individual switches: if a map light is on, press its lens to turn it off after selecting overhead OFF. If the lamp cannot be kept off, stop. Let a recently lit lamp cool before handling; ignition OFF alone is not a lamp-off setting.Manual reference · PDF 404; printed 5–111
Wrap the small flathead screwdriver in a soft cloth and use only the lens edge shown for the matched fixture. Keep the tool away from interior electrical terminals; contact can cause a short circuit. Mazda recommends dealer help for bulb replacement, so stop if access or the attachment is unclear. Leave the roof console, wiring and headliner in place.Manual reference · PDF 458; printed 6–45
For the original front overhead/map assembly, carefully release only the affected lens at the edge illustrated on printed page 6–57. Pull the bulb out as illustrated. For a separate front or rear overhead fixture, use the next step instead; do not pry the outer roof-console housing.Manual reference · PDF 470; printed 6–57
For a separate front or rear overhead fixture, carefully release its lens at the fixture-specific edge shown on printed page 6–58, then pull the bulb out. Skip this step for the front map-light assembly. Stop rather than force a lens, damaged retainer or different bulb attachment.Manual reference · PDF 471; printed 6–58
Fit the confirmed bulb of the correct fixture rating, then reinstall the lens in the reverse order of removal for that same fixture. Confirm it sits normally and is securely retained. Stop for a cracked lens or a retaining feature that will not seat; do not leave a loose lens overhead.Manual reference · PDF 471; printed 6–58
For the result record, after complete reassembly, test the affected fixture while parked. Use the overhead switch for an overhead lamp, or use the map-light lens with the overhead switch OFF for an individual map light. Record illuminated / still out / not checked, then return the controls to the desired normal setting without leaving lamps on unnecessarily. Do not continue into wiring or fuse work for a remaining outage.Manual reference · PDF 404; printed 5–111

4 Check the result

Correct fixture-specific bulb installed, lens securely refitted and the affected lamp responds normally to its switch
After full lens refitting, operate only the affected lamp with its normal control while parked. A missing check stays incomplete; a remaining outage, damaged fitting or unsecured overhead lens needs 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

Uncertain fixture / bulb, a lamp that cannot be kept switched off, a stuck or cracked lens, damaged terminals, abnormal heat, insecure lens retention or a remaining outage
Stop if the fixture or bulb cannot be matched, the lamp will not stay switched off, access requires roof / airbag-area work, a lens or terminal is damaged or retention is insecure. Ask Mazda or a suitable repairer to inspect a remaining outage without extending this procedure into electrical diagnosis.
Stop if the actual part, attachment or surface differs from the matched manual.

All observation paths

Is the failed original overhead / map fixture matched to the manual illustration and its 8 W or 10 W rating, with the overhead switch at OFF, any individually switched map light off and safe access to the lens only?

Yes — equipment, materials and safe conditions confirmed: Follow the matched-equipment plan and record only what you actually do and observe.
Not yet / uncertain: Preparation saved. Confirm the equipment, material and safe conditions before proceeding.
Uncertain fixture / bulb, a lamp that cannot be kept switched off, a stuck or cracked lens, damaged terminals, abnormal heat, insecure lens retention or a remaining outage: Stop if the fixture or bulb cannot be matched, the lamp will not stay switched off, access requires roof / airbag-area work, a lens or terminal is damaged or retention is insecure. Ask Mazda or a suitable repairer to inspect a remaining outage without extending this procedure into electrical diagnosis.

After the matched bulb and lens are fully refitted, what happened in a parked control check?

Correct fixture-specific bulb installed, lens securely refitted and the affected lamp responds normally to its switch: The actual fixture, replacement and parked switch result are recorded. A remaining outage or damaged fitting still needs inspection.
Uncertain fixture / bulb, a lamp that cannot be kept switched off, a stuck or cracked lens, damaged terminals, abnormal heat, insecure lens retention or a remaining outage: Stop if the fixture or bulb cannot be matched, the lamp will not stay switched off, access requires roof / airbag-area work, a lens or terminal is damaged or retention is insecure. Ask Mazda or a suitable repairer to inspect a remaining outage without extending this procedure into electrical diagnosis.
Work or the repeat observation is still incomplete: Preparation or incomplete work recorded. A satisfactory repeat observation is still pending.
