Volkswagen Jetta Wagon 2004 Owner's Manual page 398

TIPS AND ADVICE
On the upper side of the battery, you'll fin.d
a round "window". This window (magiC
eye) changes color as the battery charge
and electrolyte level change. This color
helps your authorized Volkswagen dealer
when diagnosing your battery.
Air bubbles in the w indow can cause an in-
accurate reading. Carefully tap on the side
of the window.
If the window has no color or is bright
yellow, the acid level is low. Add distilled
w ater to top up.
We recommend you have your authorized
Volkswagen dealer inspect your battery.
A battery that is older than five years and
has a low acid level should be replaced.
Note
Do not overfill the battery. Other-
wise battery acid will overflow
through the vent opening. This will
damage the paint and cause corro-
sion.
Always heed all WARNINGS
on page 40.
