2021 NISSAN LEAF jump start

CAUTION
• To prevent damage to the charging
equipment:
– Do not close the charge port lid
without closing the charge port
cap.
– Do not subject the charging
equipment to impact.
– Do not store and use charging
equipment in locations where the
temperature is over 185°F (85°C) •
Make sure the charge port cap is
closed on the charge port when
charging is finished. If the charge
port lid is closed when the charge
port cap is open, water or foreign
materials may enter the charge port.
• Do not charge when a vehicle body
cover is in use. This may cause dam-
age to the charge connector.
• Do not attempt to perform a jump
start on the 12-volt battery at the
same time that the Li-ion battery is
being charged. Doing so may dam-
age the vehicle or charging equip-
ment and could cause an injury. For
additional information, see “Jump
starting” (P. 6-10). •
In normal charging (AC 220 - 240 volt)
and trickle charging (AC 110 - 120 volt)
using the EVSE (Electric Vehicle Sup-
ply Equipment) provided with the ve-
hicle, NISSAN recommends using an
AC 220 - 240 volt, 50A and an AC 110-
120 volt, 15A dedicated electrical cir-
cuit and outlet. The dedicated circuit
is used to help prevent circuit dam-
age or the circuit breaker from trip-
ping due to the high draw of charging
the Li-ion battery. If the dedicated
circuit is not used, the circuit may
cause adverse interference on MCB
(Moulded Circuit Board) and house-
hold electrical appliances such as
televisions and audio systems. If the
circuit is shared, and another electri-
cal device is being used at the same
time the vehicle is charging, the
breaker may trip. A qualified electri-
cian should install a dedicated circuit
if one is not already available.

•If you used the Genuine NISSAN
Emergency Tire Sealant to repair a
minor tire puncture, it is recom-
mended that you visit a NISSAN cer-
tified LEAF dealer to replace the
TPMS sensor in addition to repairing
or replacing the tire.
• NISSAN recommends using only
Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure. To start your EV system with a booster bat-
tery, the instructions and precautions be-
low must be followed.
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.
WARNING
• If done incorrectly, jump starting can
lead to a 12-volt battery explosion,
resulting in severe injury or death. It
could also damage your vehicle.
• Explosive hydrogen gas is always
present in the vicinity of the 12-volt
battery. Keep all sparks and flames
away from the 12-volt battery.
• Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric acid solution that
can cause severe burns. If the fluid
comes into contact with anything,
immediately flush the contacted
area with water. •
Keep the 12-volt battery out of the
reach of children.
• The booster battery must be rated at
12 volt. Use of an improperly rated
battery can damage your vehicle.
• Whenever working on or near a 12-
volt battery, always wear suitable
eye protectors (for example, goggles
or industrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
12-volt battery when jump starting.
• Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
• Your vehicle has an automatic cool-
ing fan. It could come on at any time.
Keep hands and other objects away
from it.
• Always follow the instructions below.
Failure to do so could result in dam-
age to the DC/DC converter and
cause personal injury.
• Do not attempt to perform a jump
start on the 12-volt battery at the
same time that the Li-ion battery is
being charged. Doing so may dam-
age the vehicle or charging equip-
ment and could cause an injury.
JUMP STARTING
6-10In case of emergency

CAUTION
LEAF cannot be used as a booster ve-
hicle because it cannot supply enough
power to start a gasoline engine. How-
ever, a gasoline engine vehicle can be
used to jump start LEAF's 12-volt
battery.
1. If the booster battery is in another ve-hicle
OB, position the two vehicles (OA)
and
OB) to bring their 12-volt batteries
into close proximity to each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. If the 12-volt battery is discharged, the
power switch cannot be moved from
the OFF position. Connect the jumper
cables to the booster vehicle
OBbe-
fore pushing the power switch.
3. Push the P (Park) position switch to place the vehicle in the P (Park) position. 4. Switch off all unnecessary electrical sys-
tems (headlights, heater, air conditioner,
etc.).
5. Place the power switch in the OFF position.
6. Ensure vent caps are level and tight.
7. Connect jumper cables in the sequence as illustrated (
O1→O2→O3→O4).
LCE2388
In case of emergency6-11

CAUTION
• Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (for example, as illustrated),
not to the 12-volt battery.
• Make sure the jumper cables do not
touch moving parts in the motor
compartment and that the cable
clamps do not contact any other
metal.
8. Start the engine of the booster vehicle
OB.
9. While the booster vehicle
OBengine is
running, place the EV system in the
READY to drive position.
CAUTION
If the system does not start right away,
push the power switch to the OFF posi-
tion and wait 10 seconds before trying
again.
10. Af ter starting your EV system, carefully disconnect the negative cable and
then the positive cable (
O4→O3→O2
→O1) and keep in the READY to drive
position over 20 minutes to charge the
12-volt battery. 11. If necessary, connect the vehicle to a
charging station or EVSE (Electric Ve-
hicle Supply Equipment) to charge the
Li-ion battery. Be sure to read the
“Charging” section and follow the proce-
dures and guidelines described. The ve-
hicle cannot be driven until the Li-ion
battery is charged.
12. Af ter jump starting your vehicle it is rec- ommended you visit a NISSAN certified
LEAF dealer to have the 12V battery
tested.
NOTE:
If it is not possible to turn the system ON
by following this procedure, it is recom-
mended that you visit a NISSAN certified
LEAF dealer immediately. If the power limitation indicator light
illuminates, the traction motor output is
limited resulting in reduced vehicle speed.
Stop the vehicle in a safe location before
the Li-ion battery becomes completely dis-
charged and no power is available to drive
the vehicle. Contact Roadside assistance;
refer to a NISSAN Warranty Information
Booklet.
If possible, place the power switch in the
OFF position while waiting for assistance to
prevent discharging the 12-volt battery.
NOTE:
If the Li-ion battery becomes completely
discharged:
• The vehicle is automatically placed in
the ON position and it will not be pos-
sible to switch to the READY to drive
position.
• The vehicle is automatically switched to the N (Neutral) position and it will not
be possible to drive the vehicle.

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.
