.The A/C-Heater Timer (Climate Ctrl. Timer)
settings cannot be modified while it is
operating. If timer settings are modified
while the A/C-Heater Timer (Climate Ctrl.
Timer) is operating, these changes will be
reflected the next time the A/C-Heater Timer
(Climate Ctrl. Timer) operates.
. When charging is set as the first priority, the
A/C-Heater Timer (Climate Ctrl. Timer) does
not start until 10 segments of the LI-ION
BATTERY AVAILABLE CHARGE GAUGE
are illuminated.
. When the climate control is set as the first
priority, the climate control system will be
turned on as scheduled by the A/C-Heater
Timer (Climate Ctrl. Timer) regardless of the
remaining battery energy.
. Even when the climate control is set as the
first priority, the climate control system will
be turned off when the climate control
spends more electric than the charging Li-
ion battery.
. The Li-ion battery may not charge or may
even become discharged if the A/C-Heater
Timer (Climate Ctrl. Timer) or remote climate
control is used in low ambient temperatures.REMOTE CLIMATE CONTROL
This vehicle incorporates a communication
device that is called a TCU (Telematics Com-
munication Unit). The communication connec-
tion between this unit and NISSAN CARWINGS
Data Center allows for various remote function
services.
Even when away from the vehicle, climate
control can be started by accessing the
NISSAN CARWINGS Data Center website
using a cellular phone or a personal computer.
When operation is started, or at the set start
time, the NISSAN CARWINGS Data Center
accesses the vehicle. When the vehicle receives
a command for remote operation, the climate
control immediately turns ON and operates for
the specified period of time. Confirmation of the
ON/OFF of the climate control operation can be
checked by accessing the website or by e-mail.
Establishing the CARWINGS
TMservice is ne-
cessary before using the service. See LEAF
Navigation System Owner’s Manual.

speed driving you may feel that regenerative
brake provides less deceleration than the engine
braking in an ordinary vehicle. This is normal.
Less deceleration is provided by the regenera-
tive brake system when the Li-ion battery is fully
charged. Regenerative brake is automatically
reduced when the Li-ion battery is fully charged
to prevent the Li-ion battery from becoming
overcharged. Regenerative brake is also auto-
matically reduced when the battery temperature
is high/low (indicated by the red/blue zones on
the battery temperature gauge) to prevent Li-ion
battery damage.
The brake pedal should be used to slow or stop
the vehicle depending on traffic or road condi-
tions. The vehicle brakes are not affected by
regenerative brake system operation.
NOTE:
.When applying the regenerative
brakes, you may hear a sound coming
from the regenerative brake system.
This is a normal operating character-
istic of an EV (Electric vehicle) .
. If the power switch position is in a
position other than ON or READY to
drive, you can stop the vehicle by
depressing the brake pedal. However,
greater foot pressure on the brake pedal will be required to stop the
vehicle, and the stopping distance will
be longer.
. When depressing the brake pedal, the
braking pedal feel will not be smooth
or may change when the cooperative
regenerative brake system activates.
However, the electronically controlled
brake system is operating normally and
this does not indicate a malfunction.
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake pads and shoes
faster and will reduce driving range.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
select ECO position before going down a slope
or long grade. Overheated brakes may reduce
braking performance and could result in loss of
vehicle control.

in the P (Park) position, and the electric
parking brake cannot be applied. If this
occurs, place suitable blocks at both
the front and back of a wheel to prevent
the vehicle from moving. Failure to
block a wheel may allow the vehicle to
move unexpectedly which may result in
serious personal injury or death.
To place the vehicle in the READY position so
the vehicle can be driven, charge the Li-ion
battery until the driving range on the instrument
panel changes from “---” to a numeric distance.

webbing for cuts, fraying, wear or damage.
Steering wheel:Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
emits from the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that
the wipers and washers operate properly and
that the wipers do not streak.
Under hood and vehicle
The maintenance items listed here should be
checked periodically.
12-volt battery*: Check the fluid level in each
cell.
It should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
12-volt battery fluid level.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir. Coolant level*:
Check the coolant level when
the motor compartment is cold.
Fluid leaks: Check under the vehicle for water
or other fluid leaks after the vehicle has been
parked for a short period of time. Water dripping
from the air conditioner after use is normal. If you
notice any leaks, check for the cause and have it
corrected immediately.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure that
the hoses have no cracks, deformation, rot or
loose connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan and frame. At
the end of winter, the underbody should be
thoroughly flushed with plain water, being care-
ful to clean those areas where mud and dirt may
accumulate. For additional information, see
“Cleaning exterior” in the “7. Appearance and
care” section.
Windshield washer fluid*: Check that there is
an adequate amount of fluid in the reservoir.

tery automatically being charged by
the Li-ion battery. See “Charging
the 12-volt battery” in the “EV.
Overview” section.
This “8. Maintenance and do-it-yourself” section
gives instructions regarding only those items
that are relatively easy for an owner to perform.
A genuine NISSAN Service Manual is also
available. See “Owner’s Manual/Service Manual
order information” in the “9. Technical and
consumer information” section.
You should be aware that incomplete or
improper servicing may result in operating
difficulties and could affect your warranty cover-
age. If in doubt about any servicing, we
recommend that it be done by a NISSAN
certified LEAF dealer.

1. Remove the cell plugs*A.
2. Add distilled water up to the UPPER LEVEL
*1line.
If the side of the 12-volt battery is not clear,
check the distilled water level by looking
directly above the cell; the condition
*1indicates OK and the condition*2needs
more to be added.
3. Tighten cell plugs
*A.
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 operat-
ing 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.
If jump starting is necessary, see “Jump starting”
in the “6. In case of emergency” section. If the
power switch does not switch to READY to drive
position by jump starting, the 12-volt battery
may have to be replaced. Contact a NISSAN
certified LEAF dealer.
