In case of emergency -> Jump starting for Your Nissan Leaf 4 Door Second Generation (2018-2025)

JUMP STARTING  
To start your EV system with a booster bat-  
tery, the instructions and precautions be-  
low must be followed.  
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.  
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.  
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.  
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.  
WARNING  
Do not attempt to jump start a frozen  
battery. It could explode and cause  
serious injury.  
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.  
Your vehicle has an automatic cool-  
ing fan. It could come on at any time.  
Keep hands and other objects away  
from it.  
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.  
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 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.  
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.

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 bat-  
tery.
