WARNING
-=
Whenever working on the battery or on the
electrical system, there is the risk of injury,
accident and even fire. Read and heed the fol-
lowing WARNINGS:
- Always wear eye protection . Do not let bat-
tery acid or any lead particles get on your
skin or clothing. Shield your eyes. Explosive
gases can cause blindness or other injury .
- Battery acid contains sulfuric acid . Sulfuric
acid can cause blindness and severe burns.
- Always wear gloves and eye protection. Do
not tilt the battery because acid could leak
out of the ventilation openings.
- If you get battery acid in your eyes or on
your skin, immediately rinse with cold wa-
ter for several minutes and get medical at-
tention .
- If you should ingest any battery acid, seek
medical attention immediately .
- Do not expose the battery to an open flame,
electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and nega-
tive cables.
- When working on the battery, be sure not to
short-circuit the terminals with tools or oth-
er metal objects. This would cause the bat-
tery to heat up very quickly, which could
lead to damage or explosion and personal
injury .
- When a battery is charged, it produces hy-
drogen gas which is explosive and could
cause personal injury .
- Always keep the battery well out of the
reach of children .
- Before work is done on the electrical sys-
tem, disconnect the negative ground cable.
- Before performing any work on the electri-
cal system, switch off the engine and igni-
tion as well as any electrical equipment . The
negative cable on the battery must be dis-
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights .
-
Checking
and Filling
- Before disconnecting the battery, switch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis-
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off. Re-
connect the positive cable first and then the
negative cable. Never interchange the ca-
bles - this could start a fire!
- Never charge a frozen or a thawed -out bat-
tery . It could explode! If a battery has fro-
zen, then it must be replaced. A discharged
battery can freeze over at 32 °F (0 °C).
- Make sure the vent hose is always attached
to the opening on the side of the battery.
- Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.

Note
- Do not disconnect the vehicle battery when
the ignition is on or when the engine is run-
ning, otherwise, you will damage electronic
components in the electrical system.
- If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing", otherwise it
will be damaged and will then have to be re-
placed.
- When opening the doors, the windows low-
er approximately 10 mm automatically. This
function is not available when the battery is
disconnected, which means there is a risk
that the door seal or the window could be
damaged .
