Air suspention lights on battery is dead how to fix it

You have a problem in the air suspension. There are several options for fixing this. The system has a diagnostic plug which can quickly and easily indicate what part is bad.
The dealer will have the tools, you will have to ask anywhere else you want to go if they have the diagnostic tool.

If you turn off the air suspension switch in the trunk you can charge the battery and it should stay charged.
You can start the car and then switch the suspension on to get to a repair shop. For that matter, you can turn off the air suspension each time you park your car to save your battery.

You will damage the metal parts in the suspension if you drive the car without the air pump turned on. The problem may be 1 simple switch or something bigger. There are places which patch or recondition the rubber bags if that is the problem.

I usually recommend Autozone or Oreillys for a free scan but not all have the suspension tester. They also could not repair it for you but may have the parts.
