12V starter battery
WARNING
 When installing the 12V starter battery,
start connection with the positive (+) ter-
minal. If connection is started from the
negative (-) terminal, sparks will occur if
the positive (+) terminal touches any other
parts, and this may cause the 12V starter
battery to explode.
NOTE
 Remove the 12V starter battery upper cover
before disconnecting the terminal of 12V
starter battery. Refer to "Removing and
installing the 12V starter battery upper
9
cover" on page 9-8.
 Open the terminal cover (A) before discon-
necting or connecting the positive (+) termi-
nal of the 12V starter battery.

9-10 Vehicle care and maintenance
WARNING
 Open doors and windows in any closed
space where you may be charging or
working with the 12V starter battery.
 Always wear protective clothing and gog-
gles when working with the 12V starter
battery, or have a skilled automobile tech-
nician do it.
 If you are quick-charging your 12V
starter battery, first disconnect the 12V
starter battery cables.
 In order to prevent a short circuit, be sure
to disconnect the negative (-) terminal
first, and reconnect it last.
 If the electrolyte level is very low, have the
12V starter battery checked at a certified
i-MiEV dealer.
 12V starter battery terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
CAUTION
 When replacing the 12V starter battery,
remove the connected positive (+) and nega-
tive (-) terminals after turning the electric
motor switch to the "LOCK" position and
waiting at least 1 minute. If the 12V starter
battery terminal is removed just after the
electric motor switch is turned to the
"LOCK" position, this may cause damage to
components of the electric motor unit.
NOTE
 Before cleaning the 12V starter battery,
tighten all the filler port caps to keep dirt and
moisture out.
 Check each 12V starter battery terminal for
corrosion. If necessary, clean the terminals
with a solution of baking soda and water.
Grease the posts and clamps after cleaning or
tightening them.
 Check to see that the 12V starter battery is
securely installed and cannot be moved. Also
check each terminal for tightness.
 If you will not be driving your vehicle for a
long period of time, remove the 12V starter
battery and store it in a place where the 12V
starter battery fluid will not freeze. Memory
data for settings made by the user may be
erased when the 12V starter battery is
removed. If this happens, reset the settings
again using the relevant procedures. The
12V starter battery only should be stored
with a full charge.
