Charge System
One of the original “idiot” lights, the symbol to the left indicates a serious problem with the Charging System. The vehicle should be brought to a complete stop as quickly as possible or the vehicle may simply stop running in the middle of traffic. Roadside assistance will be necessary.
- But, before we continue, are you sure this is your symbol?? If yes, then read on.
- Otherwise return to our main Picture Symbols page and scan again!
In most cases, there are two possible scenarios: a bad battery, which will not allow itself to be charged, or a failing alternator, which is no longer sending enough charge to the battery. In either case, your vehicle will soon stop running. In some cases, a failing alternator will cause a weak battery to fail as well, and both will need to be replaced.
Note that Electric Vehicles (EVs) also use a 12-volt battery for start up, and this same symbol may be displayed. It is an issue with the low voltage battery (12-volt) not the high voltage battery and points out an issue either with charging the 12-volt battery or with the battery itself.

Note that if the word Main is seen beneath the battery image, the light is actually a Hybrid Battery Trouble Indicator. The vehicle’s hybrid battery must be serviced by your dealer or qualified service professional as soon as possible.
