your authorized Audi dealer or quali­
fied workshop immediate ly. Because the vehi­
cle battery is discharg ing, turn off all unnec ­
essary electrical equipment such as the rad io .
Seek professional assistance if the battery
charge level is too low .
r•j Low battery charge: battery will be
charged while driving
If the indicator light turns on and the mes­
sage appears, there may be limited starting
ability.
If this message turns off after a litt le while,
