Nissan LEAF 2023 Owners Manual
10.3.4. If the Li-ion battery becomes completely discharged
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 discharged and no power is available to drive the vehicle. Contact Roadside assistance, see your NISSAN LEAF Warranty Booklet and Maintenance Record.
If possible, place the power switch in the OFF position while waiting for assistance to prevent discharging the 12-volt battery.
If the Li-ion battery becomes completely discharged:
The vehicle is automatically placed in the ON position and it will not be possible to switch to the READY position.
The vehicle is automatically switched to the N (Neutral) position and it will not be possible to drive the vehicle.
If the vehicle is in the N (Neutral) position and the Li-ion battery and the 12-volt battery become completely discharged, the vehicle can not be placed in the P (Park) position, and the 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.
Some vibration may occur when the vehicle is stopped in case the Li-ion battery becomes completely discharged. This is not a malfunction.
If the Li-ion battery is completely discharged, it is required to charge until the low battery charge warning light (yellow) turns off (white).
