anteed. When connecting the battery terminal clamps, always
keep the tightening specification for the corresponding vehicle
from the repair manual in mind. Refer to ⇒ Electrical Equip‐
ment; Rep. Gr. 27 ; Battery . If the battery post clamps are not

WARNING
Risk of injury. Follow all warning messages and safety pre‐
cautions.

Visual Indicator General Information:
The visual indicator provides information concerning the electro‐
lyte level and the Battery - A- charge level.
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 indi‐
cator is more accurate.
Note
♦ Air bubbles can form under the visual indicator, especially if a
Battery - A- was recharged or if the Battery - A- was charged
while driving. These bubbles may cause the visual indicator to
read inaccurately.
♦ As the charge indicator is located in a single cell, the indication
is only valid for that cell. An exact assessment of battery con‐
dition should always be confirmed by performing battery test.
Refer to ⇒ “2.6.3 Battery Load Test”, page 18 .
♦ The visual indicator can be installed at various locations on top
of the Battery - A- .
There Are Three Possible Color Indications
♦ »Green«: the Battery - A- is sufficiently charged.
♦ »Black«: the Battery - A- is partially charged, the charge level
is less than 65% or discharged.
♦ »No color/bright yellow«: the Battery - A- must be replaced.
