Nissan Leaf 2018-2025 (ZE1) Owner's Manual : High voltage precautions

High-voltage components

WARNING

  • The advanced electric vehicle (EV) system in your Nissan Leaf operates using high-voltage electricity, reaching levels up to approximately 400 volts DC. Please be aware that these internal components can remain extremely hot during operation, immediately after starting, and even after the vehicle has been powered down. Exercise extreme caution around both the high-voltage electrical systems and high-temperature components to prevent accidental injury.

    Always pay close attention to all safety warning labels permanently affixed to the vehicle, as they provide critical information regarding high-voltage hazards.

  • Under no circumstances should you attempt to disassemble, remove, or replace any high-voltage components, cables, or their specific connectors. Unauthorized interference with these parts can result in catastrophic electrical shock or severe thermal burns, posing a significant risk of grave injury or fatality. For your safety, high-voltage cables are distinctly colored orange to alert you to their nature. The high-voltage infrastructure of the Nissan Leaf contains no user-serviceable parts; for any maintenance, inspection, or repairs, it is strictly recommended that you rely exclusively on a NISSAN certified LEAF dealer.
