Today after being out of town for a while, I need to jump start my CLK430

Battery was down enought to not be able to turn the engine all the
way over. Jumped and it started right away. Now I have the BAS/ABS
light is on. It was not on before the need to jump ( or when I parked it ).

I read once that sometimes when the battery goes really low this happens.

I restarted the car but lights are still on. Will they reset, or is it usually
a need to replace the switch ??

Thanks for any assistance.
