Checked on 27 October 2026 against XPENG’s 2025 English G9 manual for XOS V5.6.0, printed pages 211, 234–235. 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 air-conditioning screen and select the rear-window heating/defrost symbol. In the cited G9 manual, that control activates rear-window and exterior-mirror heating together.

Before you start

Park before looking for the control. Check that the mirror glass is not physically obstructed and do not try to scrape it with a hard object. Keep hands off heated glass and use the car’s current instructions if its climate layout differs.

Activate the combined heating function

1Open air-conditioning controlsLocate the heating and circulation controls on the G9 climate screen. Identify the rear-window heating symbol rather than the front-windscreen defrost symbol.
2Switch rear heating onSelect the rear-window heating control. The international manual describes rear-window and exterior-mirror heating under this same function.
3Allow time and observeWatch the rear glass and both exterior mirrors for improved visibility. Heating will not instantly remove heavy ice or repair damaged glass.
4Switch off when no longer neededUse the same control to turn the function off when visibility is clear, and confirm the indicator changes. Avoid extended use with the vehicle not started.

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

Check the result

The mirror surfaces and rear glass should become clearer. If one mirror remains obstructed while the other clears, record which side, temperature and operating duration for service. Do not repeatedly touch the glass to test its temperature.

Chinese owner report — anecdotal context

A G9 owner discusses wet-weather visibility in a Chinese rain-driving report. The international manual, rather than the report’s voice commands or driving-assistance choices, verifies the heating control used here. Report dated 2024-05-11; domestic-market anecdote.
