XPENG G9 damp air-conditioning smell: how to check Intelligent Cleaning

A damp smell after air-conditioning use can make an owner look for a drying setting. The international G9 manual calls its moisture-related feature Intelligent Cleaning; domestic posts may use different labels.

Checked on 27 October 2026 against XPENG’s 2025 English G9 manual for XOS V5.6.0, printed pages 236–238. Chinese-market owner reports identify the question; they do not establish a common defect, a guaranteed fix, or matching export equipment. Stop if your car’s controls differ.

THE QUICK ANSWER

Open the climate settings and the smart-mode control at the lower right. Check the Intelligent Cleaning option described in the handbook. It can detect water in the climate system after you exit and lock the vehicle while air-conditioning was operating.

Before you start

Check for wet mats, spilled liquid or damp luggage before changing settings. A persistent smell, visible leak or unhealthy air needs inspection. A drying feature is not a verified repair for a contaminated filter or water entering the cabin.

Check the documented cleaning feature

1Open climate smart modesBring up the air-conditioning screen and use the smart-mode control at the lower right of climate settings. Read the available options rather than translating a Chinese menu literally.
2Check Intelligent CleaningEnable or review Intelligent Cleaning if it is offered on your matching version. The manual explains its moisture-detection behaviour after locking.
3Finish a normal journeyIf air-conditioning was operating, leave the vehicle and lock it normally. Do not remain inside to run improvised high-temperature cleaning routines.
4Compare the next useNote whether the odour persists on the next start and whether the cabin itself is damp. Record the conditions if you need the filter, drains or climate system inspected.

Tick steps as you go. Your progress stays in this tab.

Check the result

The manual describes reduced moisture and odour risk, not guaranteed removal of every smell. Intelligent Cleaning uses some energy. If the car remains damp or odorous, arrange an inspection instead of repeatedly relying on fragrance or unsupported cleaning methods.

Chinese owner report — anecdotal context

A Chinese G9 owner discusses a drying feature when dealing with cabin odours. This guide uses the international manual’s Intelligent Cleaning description and does not assume identical domestic feature names. Report dated 2024-06-04; domestic-market anecdote.

Common questions

Does fan noise after locking prove a fault?+

The documented cleaning feature can operate after locking when its conditions are met; investigate unusual persistent behaviour with support.

Will this replace a dirty cabin filter?+

No. A setting does not physically replace or inspect the filter. Persistent odours need their source checked.
