GROUNDWORK — Check cold tire pressure Task: mazda-cold-tire-pressure | Content version 2.0.0 Source page: https://csl-12-auto-repair.pages.dev/tasks/mazda-cold-tire-pressure/ MODEL / APPLICABILITY [{"modelId":"mazda3-2017-us","market":"US","year":2017,"engine":"SKYACTIV-G 2.0 / 2.5 gasoline","configurations":["all","4-door","5-door","type-b-audio"]}] EXCLUSIONS Other model years and markets; imported Axela or diesel models; modified or aftermarket components with a different procedure. Snow-tire setup: the manual has additional pressure instructions on printed p.3-49; have that setup confirmed before using a standard label-only target. PREPARE [ ] Park in a safe place away from traffic. Work with the vehicle stationary, parking brake set and ignition off unless a step explicitly calls for a parked functional check. [ ] Has the vehicle been parked for at least three hours, with undamaged standard road tires and a readable pressure label? [ ] Keep children and pets away from tools, fluids and coin cells. Never enter underneath the vehicle. [ ] Reliable tire-pressure gauge [ ] Inflator if adjustment is needed [ ] Correct, secure valve caps [ ] Your vehicle’s door-frame pressure label OBSERVE & RECORD Observation date: __________ Vehicle / equipment confirmed: __________ Copy each real label target and cold gauge reading by wheel position, including any separate spare specification and initialization result. Affected road-tire label target (psi): __________ Affected road-tire cold reading (psi): __________ Wheel position and remaining tire readings: __________ Three-hour parked condition, adjustment and TPMS confirmation: __________ Before care: __________ STEPS 1. [ ] For this routine US placard check, use tires cold after the vehicle has been parked for at least three hours, as defined on printed page 8-30. Do not bleed warm tires to the cold target. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=563 | PDF page 563 2. [ ] Read the recommended tire pressures on the driver-side door-frame label and compare tire sizes with the vehicle specification. This plan does not supply a guessed PSI. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=563 | PDF page 563 3. [ ] Measure each road tire while cold and record how it compares with the label. Warm tires read higher; do not bleed warm tires down to a cold specification. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=564 | PDF page 564 https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=563 | PDF page 563 4. [ ] If undamaged standard road tires need adjustment, use the door-frame label target and recheck with a gauge. Refit Mazda-genuine valve caps as required by printed page 6-40. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=453 | PDF page 453 5. [ ] Inspect the spare’s pressure separately if equipped, using its own specified pressure rather than the road-tire setting. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=453 | PDF page 453 6. [ ] If equipped with the manual’s TPMS set switch, initialize only after all four tires are set to the door-frame label pressure: park safely with parking brake firmly applied, switch ignition ON, press and hold the set switch, and verify two warning-light flashes and one beep. Never initialize while driving or use initialization to conceal a damaged / low tire. If the switch or confirmation differs, seek help. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=285 | PDF page 285 7. [ ] If one tire repeatedly needs inflation, arrange inspection. A pressure check cannot clear a damaged tire for driving. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=454 | PDF page 454 8. [ ] Copy each real label target and cold gauge reading by wheel position, including any separate spare specification and initialization result. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=453 | PDF page 453 DECISION CHECKS Has the vehicle been parked for at least three hours, with undamaged standard road tires and a readable pressure label? Yes — ready for this check → Continue with the steps, stopping if the real component differs from the manual. Not yet / not sure → Preparation saved. Return when the condition is confirmed; leave the vehicle untouched. A tire is flat, damaged, repeatedly losing air or the label is unreadable → Damage, recurring pressure loss or a missing specification: arrange tire inspection; do not drive on a flat tire. What was verified after measuring / adjusting? Cold pressures match the vehicle label, caps secure; any required TPMS follow-up identified → Were all road tires checked against the actual label, and was required initialization confirmed after adjustment? Damage, recurring pressure loss or a missing specification: arrange tire inspection; do not drive on a flat tire. → Damage, recurring pressure loss or a missing specification: arrange tire inspection; do not drive on a flat tire. I have only prepared the plan → Plan prepared; no physical maintenance result recorded. Were all road tires checked against the actual label, and was required initialization confirmed after adjustment? All applicable readings and initialization recorded; no damage or loss → Cold pressures match the vehicle label, caps secure; any required TPMS follow-up identified The observation or repeat check is still incomplete → Plan prepared; no physical maintenance result recorded. A tire loses air again, warning persists or a specification is uncertain → Damage, recurring pressure loss or a missing specification: arrange tire inspection; do not drive on a flat tire. RECHECK At the next comparable cold check, does a tire need air again, and has the TPMS warning returned? After care: __________ Retest: not checked / improved / unchanged / worse If an earlier condition changes, reassess the later checks and result. RESULT CHECK What was verified after measuring / adjusting? Cold pressures match the vehicle label, caps secure; any required TPMS follow-up identified Record only the result you actually observed. A saved web checklist is not confirmation that a vehicle has been repaired. Were all road tires checked against the actual label, and was required initialization confirmed after adjustment? At the next comparable cold check, does a tire need air again, and has the TPMS warning returned? STOP CONDITIONS A tire is flat, damaged, repeatedly losing air or the label is unreadable Damage, recurring pressure loss or a missing specification: arrange tire inspection; do not drive on a flat tire. A part, label, connector or fastener differs from the cited manual; access requires raising the vehicle; you cannot identify the correct component. SERVICE HANDOFF Take the recorded observations, their dates and any actual work history to the service provider. Damage, recurring pressure loss or a missing specification: arrange tire inspection; do not drive on a flat tire.
