Battery
The maintenance-free battery is
located in the trunk under the
right-hand wheel well cover panel.
The service life of the battery is
dependent on its condition of
charge. The battery should always
be kept sufficiently charged, in
order to last an optimum length of
time.
Therefore, we strongly recom­
mend that you have the battery
charge checked frequently, and
corrected if necessary, espe­
cially if you use the vehicle less
than approximately 200 miles
(300 km) per month, mostly for
short distance trips, or if it is
not used for long periods of
time.
Only charge a battery with a
battery charger after the battery
has been disconnected from the
vehicle electrical circuit.
When removing and connecting
the battery, always make sure that
all electrical consumers are off
and the key is in steering lock
position 0.
While the engine is running the
battery terminal clamps must not
be loosened or detached, other­
wise the alternator and other
electronic components would be
damaged.
Battery Recycling
Batteries contain materials that
can harm the environment with
improper disposal.
Large 12 Volt storage batteries
contain lead, and smaller watch-
type batteries (such as in the
Infrared Remote Control Unit) may
contain mercury.
Recycling of batteries is the
preferred method of disposal.
Many states require sellers of
batteries to accept old batteries for
recycling.
Warning!
Never lean over batteries
while connecting, you might
get injured.
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 and
seek medical help.
A battery will also produce
hydrogen gas, which is
flammable and explosive.
Keep flames or sparks away
from battery, avoid improper
connection of jumper cables,
smoking etc..
