1. Turn the plastic nut (A) counterclockwise, and then remove the 12V starter battery upper cover (B).
1. Install the 12V starter battery upper cover (B) onto the 12V starter battery, and then push the plastic nut (A) in the direction shown by the arrows to secure the cover.

Before checking the 12V starter battery elec-trolyte level, remove th
e 12V starter battery’s
upper cover. The electrolyte level
must be between the
limits shown on the outside of the 12V starterbattery. Fill it with distilled water as needed. The inside of the 12V starter battery is divided into several compartments. Take the cap off of each compartment and fill to the mark.Do not fill above the t
op line because a spill
during driving could cause damage.

 Be careful not to lose the removed plastic nut.
To install
CAUTION Be sure to install the 12V starter battery upper cover. Otherwise,
the battery electro-
lyte may spill and
cause a malfunction.
When installing the 12V
starter battery upper
cover and plastic nut
do not touch the cool-
ing fan or other moving parts under the hood.Be especially carefu
l that the cables, your
clothing or hair, etc.,
do not get caught in the
cooling fan or ot
her moving parts.
NOTE
Be sure to install the plastic nut in the correct direction.

ter battery electro-
lyte level before connecting booster cables.

The 12V starter battery is weaker in cold tem- peratures. This has to do with its chemicaland physical propertie
s and is why a very
cold 12V starter battery, especially one with a
low charge, will have a hard time starting your vehicle.It is recommended that you have your 12V starter battery and charging system checked by a certified i-MiEV dealer before the startof cold weather. If necessary, have it charged. This will guarantee more reliable starting, and longer 12V starter battery life.

To disconnect the 12V starter battery cable,stop the electric motor.
Disconnect the nega-
tive (-) terminal first, then the positive (+) ter- minal. To reconnect th
e 12V starter battery,
first connect the positi
ve (+) terminal and
then the negative (-) terminal, before starting the vehicle.
 After checking the 12V starter battery electrolyte level, make sure the caps arefitted securely. If any of the caps cannot be re-secured to the 12V starter battery, replace the 12Vstarter battery. Electrolyte (battery acid) is made of corro- sive diluted sulfuric acid. If it spills on nearby parts, it can crack, stain, or dis- color them. And if gets on your skin or inyour eyes, it can cause burns or blindness. Please observe the following handling instructions:• If electrolyte gets on plastic parts orother nearby parts, wi
pe it off with a soft
cloth or chamois soak
ed in a solution of
water and neutral detergent then imme- diately rinse the affected parts withplenty of water.• If electrolyte gets on your hands orclothes, rinse thoroughly with water. If electrolyte gets in your eyes, flush them with water immediat
ely and get immedi-
ate medical attention.

Disconnection and connection
WA R N I N G Never disconnect the
12V starter battery
while the electric motor unit is running, or you could damage the
vehicle’s electrical
parts.  Never short-circuit
the 12V starter bat-
tery. This could cause it to overheat and be damaged.  Keep sparks, cigarette
s, and flames away
from the 12V starter battery because the 12V starter battery could explode.
 When installing the
12V starter battery,
start connection with the positive (+) ter-minal. If connection is started from thenegative (-) terminal,
sparks will occur if
the positive (+) termin
al touches any other
parts, and this may cause the 12V starterbattery to explode.NOTE
 Remove the 12V starte
r battery upper cover
before disconnecting the terminal of 12V starter battery. Refer to “Removing and installing the 12V st
arter battery upper
cover” on page 9-8.  Open the terminal cover (A) before discon- necting or connecting the positive (+) termi- nal of the 12V
starter battery.
 Loosen the nut (B), and then disconnect the 12V starter batt
ery cable from the positive
(+) terminal.WA R N I N G

It is important to familiarize yourself with the following terms:  Cold tire pressure: • The measured pressure after the vehiclehas been parked for
at least three hours,
or • The measured pressure when the vehicleis driven less than 1 mile (1.6 km) after having been parked for three hours.
 Maximum inflation pressure: the maxi- mum permissible cold
tire inflation pres-
sure for this tire.  Recommended inflation pressure: the inflation pressure for optimum tire perfor- mance.
WA R N I N G Open doors and wind
ows in any closed
space where you may be charging orworking with the 12V starter battery.  Always wear protective clothing and gog- gles when working wi
th the 12V starter
battery, or have a sk
illed 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 (-) terminalfirst, 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 te
rminals 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 andwaiting at least 1 minut
e. 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 terminalswith a solution of baking soda and water. Grease the posts and cl
amps 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 driv
ing your vehicle for a
long period of time, re
move the 12V starter
battery and store it in a place where the 12V starter battery fluid wi
ll 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 settingsagain using the releva
nt procedures. The
12V starter battery
only should be stored
with a full charge.
Tires
WA R N I N G Driving with tires that are worn, damaged or improperly inflated is dangerous.These type tire conditions will adversely affect vehicle performance. These type tire conditions can also cause atread separation or blowout which may result in an accide
nt causing serious
injury or death. Tires degrade over ti
me with age even
when they are not being used. It is recom-mended that tires ove
r 6 years generally
be replaced even if
damage is not obvious.

 Some fuses may not be installed on your vehicle, depending on
the vehicle model
or specifications.  The table above show
s the main equip-
ment corresponding to each fuse.

1. Before replacing a fuse, always turn off the electrical item connected to the fuse and turn the electric motor switch to the “LOCK” position.
2. Remove the fuse puller (A) from the inside of the fuse cover in the passengercompartment. 3. Clamp it on the fuse you wish to remove, and pull the fuse straight out from the fuseblock.
4. Use the fuse location diagrams and their corresponding tables, to check the fusethat is related to the problem. If the fuse is not blown, something
else must be caus-
ing the problem.Contact a certified i-
MiEV dealer to have
the problem checked. 5. Insert a new fuse of the same capacity securely into the appropriate slot.
