2018 AUDI A4 warning lights

@ Tips
The discharged battery must be properly con­
nected to the vehicle's electrical system .
When jump starting or charg ing the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negative ground cable to the negative ground
post of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!
