The battery-shaped warning light usually means the 12-volt charging system is not charging the battery while the engine runs. It does not automatically mean the battery itself is the only cause.
Reduce electrical load
Turn off nonessential electrical accessories when safe to do so. Follow your owner’s manual because vehicle instructions can vary.
Plan for prompt help
A charging fault can leave the vehicle unable to restart or running on limited battery power. Arrange professional diagnosis promptly.
Do not confuse warnings
Warning icons and messages differ by vehicle. Use the manual for the exact symbol and instructions.
