AITO M5 maintenance schedule (China)
Real, source-extracted maintenance intervals from the official China owner manual.
Safety and service note
What is confirmed
The official 2025 China owner manual gives a genuine first-service point (3 months or 5,000km, whichever comes first) and a routine-maintenance cycle of every 12 months or 10,000km (whichever comes first), tabulated out to 180 months/150,000km. Within that structure, several items have their own specific replacement intervals: range-extender oil and oil filter (1 year or 10,000km of range-extender operation), air filter (clean at 1 year/10,000km, replace at 2 years/20,000km), spark plugs (3 years/30,000km), range-extender coolant (4 years/100,000km), fuel filter (3 years/100,000km), brake fluid (3 years/60,000km), cabin/AC filter (1 year/20,000km), reduction-gear oil (5 years/100,000km, for both the Jinkang-motor and Huawei-motor variants named in the manual), and drive-motor/HV-battery coolant (4 years/100,000km). The range-extender-specific items apply only to the Extended-Range trims, not the Pure Electric trim; the HV-battery, charging-system, drive-motor and coolant items apply to all trims.
Scope and safety boundaries
This is the real maintenance schedule from the official China manual and is scoped to the China market. This is a reference summary, not a repair guide; high-voltage battery, charging-system and range-extender work must be performed by authorized AITO/Seres service, never as a DIY task.
| Topic | Status |
|---|---|
| Official China manual maintenance/warranty/warning-light facts | Published with citations (China market) |
| DTC codes / global-export manual / accessories catalogue | Research only until an official source is found |
| Philippines / UAE market facts | Kept separate from China, official regional facts only |
Important
Check market, powertrain (EV vs EREV), trim, VIN and official AITO/Seres/dealer confirmation. Safety-critical topics stay service-only.
Frequently asked questions
Is this page official AITO content?
No. It is an AutoTechHelp source-backed owner-help page. Official AITO/Seres sources, including the directly-extracted China owner manuals, are cited at the bottom.
Does this apply to AITO M6, M7, M8, M9 or Seres SF5/5?
No. This page covers AITO M5 (问界M5) only. Other AITO models and Seres-branded vehicles are modeled separately and their facts are not merged in here.
Are EV and EREV (range-extender) facts the same?
No. Battery, range, motor and maintenance facts differ between the Pure Electric Ultra trim and the Extended-Range Ultra RWD/AWD trims. Do not mix them.
Does an official owner manual exist?
Yes. AutoTechHelp directly downloaded and extracted the official China owner manual PDFs (2025 and 2024 editions). No confirmed global/export-market manual was found this rollout.
Is the maintenance schedule real or invented?
It is extracted directly from the official 2025 China owner manual's maintenance chapter, including specific intervals for range-extender oil, spark plugs, brake fluid, cabin filter, reduction-gear oil and coolant. It is scoped to the China market.
Is the warranty information official?
Yes, for the China market. The 4-year/100,000km vehicle warranty, 8-year/160,000km core-component warranty and wear-item warranty table are extracted from the official 2025 China owner manual, which states it applies to mainland China only.
Are DTC/error codes published for this model?
No. The manual's dashboard chapter documents named warning lights but not numeric fault codes, and no official diagnostic manual with exact codes was found.
Can I repair the car from this page?
No. High-voltage battery, range-extender, brakes, steering, airbags, ADAS and wiring repair procedures are excluded.
Is the Philippines market the same as China?
No. The Philippines page markets AITO M5 only as a range-extended (EREV) vehicle and does not confirm a Pure-Electric variant, China-market pricing, or China-market warranty terms for that market.
How often are sources checked?
The seed stores checked dates and review tasks; pages should be rechecked as AITO/Seres publishes new manual editions or regional pages.
