The 12-volt battery*Ais located on the
left hand side of the trunk behind an
access panel.
. Keep the battery surface clean and dry.
Clean the battery with a solution of
baking soda and water.
. Make certain the terminal connections
are clean and securely tightened.
. If the vehicle is not to be used for 30
days or longer, disconnect the negative
(-) battery terminal cable to prevent
discharge.
WARNING
. Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by the battery is explosive. Do not
allow battery fluid to contact your skin,
eyes, fabrics or painted surfaces. After
touching a battery, do not touch or rub
your eyes. Thoroughly wash your hands.
If the acid contacts your eyes, skin or
clothing, immediately flush with water
for at least 15 minutes and seek medical
attention.
. The Hybrid vehicle uses a special bat-
tery. If the battery needs to be replaced,
use a battery of the same design. Using
the wrong battery can cause hydrogen
gas to build up in the vehicle, which
could lead to an explosion and personal
injury.
. When working on or near a battery,
always wear suitable eye protection and
remove all jewelry.
. Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
