Two checks

I had similar problem before, the dealer did the followings and the problem was fixed:

(1) All of the 4 tires pressure should be similar with no much difference---balance. If anyone of them is much higher than others, the 气压警告灯亮.

(2) The tire pressure should not be set much higher than that the manual suggested. If for some reasons, such as for saving gas, setting up too much higher of tire pressure, the 气压警告灯亮.
