Checking the vehicle battery acid level
If the lighting conditions are poor, use a flashlight so that you can clearly see the battery acid level
indicator and tell what color it is. Never use an open flame or an unprotected light source.
The round battery window (acid level indicator) on the top of the battery changes color, depending
on the battery's electrolyte level.
Battery electrolyte level is too low. The vehicle battery may need to be re‐
placed. Have it checked by an authorized Volkswagen dealer or an authorized Volkswagen
Service Facility.
Battery electrolyte level is satisfactory.
