Battery

The battery is located in the trunk.
Check fluid level in each cell
approximately every four weeks,
and more frequently during the
summer and in hot climates.
Refill battery only with distilled
water. Do not use metal funnels or
push through the overfill-protection
diaphragms in filler holes.
The battery is completely filled
when the water stops draining
through the overfill-protection
diaphragm.
»
To check the battery charge with a
hydrometer, push its tip through
the overfill-protection diaphragm
and take the electrolyte sample.
Coat battery terminal clamps with
acidproof grease. Keep battery
clean and dry.

The service life of the battery is
also dependent on its condition of
charge. It must be maintained suffi­
ciently charged for the battery to
last an optimum length of time.
Therefore, we recommend that you
have the battery charge checked
frequently if you use the vehicle
mostly for short distance trips, or if
it is not used for long periods of
time.
Only charge battery with a battery
charger when it is disconnected
from the vehicle electrical circuit.
Warning!
Battery fluid contains sulfuric acid.
Do not allow this fluid to come in
contact with eyes, skin, or clothing.
In case it does, immediately flush
affected area with water; if neces­
sary seek medical help.
A battery will also produce hydro­
gen gas, which is flammable and
explosive. Keep flames or sparks
away from battery, i. e. improper
connection of jumper cables, ciga­
rette smoking, etc..
While the engine is running the bat­
tery terminal clamps must not be
loosened or detached as otherwise
the alternator and other electronic
units would be damaged.
Only tow vehicle with the battery
connected.
