Battery With Visual Indicator
There is risk of explosion if the visual indicator is colorless or light yellow!
- Do not jump start the vehicle.
- Do not check or charge the battery.
- Replace the battery.
The battery is in the luggage compartment.
Removal Procedures:
-- Raise the luggage compartment floor covering and secure.
-- Remove the nut -1- for the vehicle tool kit and remove the cover with the vehicle tool kit -2- or temporary spare tire.
Procedure:
-- Check the battery housing for the following:
- Corrosion or damage to the battery terminals
- Mechanical damage to the battery housing or cover, recognizable by electrolyte leakage or crystallization on the damaged location.
-- Replace damaged batteries.
-- Before checking the electrolyte level, carefully tap on the visual indicator -arrow- with the handle of a screwdriver.
-- 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.
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.
