–The Climate Ctrl. Timer is not ac-
tive or operating. For additional
information, see “Climate Ctrl.
Timer” (P. 4-38).
– The 12-volt battery is not being
charged by the Li-ion battery and
that all charging status indicator
lights are off. For additional infor-
mation, see “Charging the 12-volt
battery ” (P. EV-5) and “Charging
status indicator lights” (P. CH-49).
• The power switch is in the OFF posi-
tion. Place the power switch in the ON
position and then in the OFF position
to prevent the 12-volt battery auto-
matically being charged by the Li-ion
battery. For additional information,

other positions. The “Do-it-yourself ” section gives instruc-
tions regarding only those items that are
relatively easy for an owner to perform.
A Genuine NISSAN Service Manual is also
available. For additional information, see
“Owner’s manual/service manual order in-
formation” (P. 10-22).
You should be aware that incomplete or
improper servicing may result in operating
difficulties and could affect your warranty
coverage.

12-VOLT BATTERY
Do-it yourself8-9

• Keep the 12-volt battery surface cleanand dry. Clean the 12-volt battery with a
solution of baking soda and water.
• Make certain the terminal connections are clean and securely tightened.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec- tronic accessories that consume bat-
tery power when the EV system is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health
WARNING
• Do not expose the 12-volt battery to
flames or electrical sparks. Hydrogen
gas generated by the 12-volt battery
is explosive. Do not allow 12-volt bat-
tery fluid to contact your skin, eyes,
fabrics or painted surfaces. Af ter
touching a 12-volt battery or 12-volt
battery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If
the acid contacts your eyes, skin or
clothing, immediately flush with wa-
ter for at least 15 minutes and seek
medical attention.
• Do not operate the vehicle if the fluid
in the 12-volt battery is low. Low 12-
volt battery fluid can cause a higher
load on the 12-volt battery which can
generate heat, reduce battery life,
and in some cases lead to an
explosion. •
When working on or near a 12-volt
battery, always wear suitable eye
protection and remove all jewelry.
• 12-volt battery posts, terminals and
related accessories contain lead and
lead compounds. Wash hands af ter
handling.
• Keep the 12-volt battery out of the
reach of children.

1. Remove the vent caps with a screw-driver as shown. Use a cloth to protect
the battery case.
2. Check the fluid level in each cell. If it isnecessary to add fluid, add only distilled
water to bring the level up to the bottom
of the filler opening. Do not overfill.Re-
install the vent caps. Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the 12-volt battery fluid level.
JUMP STARTING
Jump starting provides power to the 12-
volt system to allow the electrical systems
to operate. The electrical systems must be
operating to allow the Li-ion battery to be
charged. Jump starting does not charge
the Li-ion battery. The Li-ion battery must
be charged before the vehicle can be
driven.
For additional information, see “Jump
starting” (P. 6-10). If the power switch does
not switch to the READY to drive position by
jump starting, the 12-volt battery may have
to be replaced. It is recommended that you
visit a NISSAN certified LEAF dealer for this
service.
