-- Read the battery electrolyte level using the color display. Two different results are possible:

Color display on visual indicator:	Action:
Black or green	Battery electrolyte level is OK: no further action necessary.
Colorless or light yellow	Battery electrolyte level too low: the battery must be replaced.

Installation procedures occur in reverse order.

NOTE:

The visual indicator is also called the ALI (Acid Level Indicator).

Only use the visual indicator for assessing the electrolyte level!

Bubbles can build up under the visual indicator when the battery is charging and also while driving, causing the color display to be incorrect. Gently tapping on the visual indicator dissolves these bubbles.
