Maintenance and do-it yourself -> Maintenance precautions for Your Nissan Leaf 4 Door Second Generation (2018-2025)

MAINTENANCE PRECAUTIONS  
When performing any inspection or main-  
tenance work on your vehicle, always take  
care to prevent serious accidental injury to  
yourself or damage to the vehicle. The fol-  
lowing are general precautions that should  
be closely observed.  
Park the vehicle on a level surface,  
apply the parking brake securely and  
chock the wheels to prevent the ve-  
hicle from moving. Push the P (Park)  
position switch on the shift lever or  
place the vehicle into the N (Neutral)  
position.  
CAUTION  
Do not work under the hood while  
the motor compartment is hot. Push  
the power switch in the OFF position  
and wait until it cools down.  
Avoid direct contact with used cool-  
ant. Improperly disposed coolant  
and/or other vehicle fluids can dam-  
age the environment. Always con-  
form to local regulations for the dis-  
posal of vehicle fluids.  
WARNING  
If you must work with the EV (Electric  
Vehicle) system is turned on, keep  
hands, clothing, hair and tools away  
from moving fans and any other  
moving parts.  
The EV system uses high voltage up  
to approximately DC 400 volt. The  
system can be hot during and after  
starting and when the vehicle is shut  
off. Be careful of both the high volt-  
age and the high temperature. Obey  
the labels that are attached to the  
vehicle.  
Never connect or disconnect the bat-  
tery or any transistorized compo-  
nent while the power switch is in the  
ON position.  
Make sure that the power switch is in  
the OFF or LOCK position when per-  
forming any part replacement or  
repairs.  
Your vehicle is equipped with an au-  
tomatic cooling fan. It may come on  
at any time without warning, even if  
the power switch is not in the ACC, ON  
or READY to drive position. To avoid  
injury, always disconnect the nega-  
tive 12-volt battery cable before  
working near the fan.  
Never disassemble, remove or re-  
place high-voltage parts and cables  
as well as their connectors. High-  
voltage cables are colored orange.  
It is advisable to secure or remove  
any loose clothing and remove any  
jewelry, such as rings, watches, etc.  
before working on your vehicle.  
Disassembling, removing or replac-  
ing those parts or cables can cause  
severe burns or electric shock that  
may result in serious injury or death.  
The vehicle high-voltage system has  
no user serviceable parts. It is recom-  
mended that you visit a NISSAN cer-  
tified LEAF dealer for any necessary  
maintenance.  
Always wear eye protection when-  
ever you work on your vehicle.  
Never get under the vehicle while it is  
supported only by a jack. If it is nec-  
essary to work under the vehicle,  
support it with safety stands.  
Before performing any electrical  
maintenance work on the vehicle  
such as the battery, fuses or bulb re-  
placement, confirm the following:  
Keep smoking materials, flames and  
sparks away from the 12-volt battery.  
The charge connector is removed  
from the vehicle.
