Volkswagen Polo Service & Repair Manual: “2 Color” Visual Indicator, Checking
WARNING
| Risk of injury. Follow all Warnings and Safety
Precautions. Refer to
→ Chapter „Warnings and Safety Precautions“. |
|
| Visual Indicator General Information |
| The general introduction of the “2-color” display began as a
running change in 2009. The color »green«
for the state of charge was discontinued on the “2-color”. |
| The visual indicator shows the battery acid level. |
| It is no longer possible to read the battery state of charge
using the visual indicator. It is necessary to perform a battery
test. Refer to
|
| To obtain an accurate reading, gently tap the charge
indicator with a screwdriver handle or rock vehicle slightly. By
doing this, the air bubbles that occur normally during battery
charging (even during vehicle operation) that adversely affect
charge indicator reading will be displaced. Thereby, the color
indicator of the visual indicator is more accurate. |
 Note
| Air bubbles can especially form under visual indicator when
a battery is charged, including when charged while driving. This
will cause an incorrect display. |
| The display is valid for only that one battery cell in which
the visual indicator is located. An exact assessment of battery
charge is only possible by performing a battery test. Refer to
→ Chapter „Battery Tester -VAS6161-“. |
| The visual indicator may be located on different locations
on the battery. |
| Two Visual Indicators Are Possible: |
| »Black«, the electrolyte level
is OK |
| »Bright yellow«, the electrolyte
level is too low. The Battery must be replaced. |
WARNING
| Do not check or charge batteries that have a visual
indicator that is bright yellow. Jump starting must not
be used! |
| There is a risk of explosion during testing,
charging or jump starting. |
| These batteries must be replaced. |
