When performing any inspection or maintenance work on your Nissan Leaf, it is imperative to prioritize safety to prevent serious accidental injury to yourself or damage to the vehicle's sophisticated components. The following general precautions represent essential safety standards that must be observed during any service procedure.

WARNING

• The EV system in your Nissan Leaf utilizes a high-voltage architecture of approximately 400 volts DC. This system can remain extremely hot both during and immediately after operation, even when the vehicle is powered down. Always be mindful of both the high-voltage electrical hazards and the high operating temperatures. Strictly adhere to all safety warning labels attached to the vehicle components.
• Under no circumstances should you attempt to disassemble, remove, or replace any high-voltage components, cables, or connectors. For your safety, these high-voltage cables are identified by their distinctive orange outer insulation.
• Unauthorized tampering with these specific parts or cables can lead to severe electrical shock or thermal burns, which may result in serious permanent injury or death.

  Please note that the vehicle's high-voltage system contains no user-serviceable components. It is strictly recommended that you visit a NISSAN certified LEAF dealer for any necessary maintenance or diagnostics.

• Always park the vehicle on a flat, level surface, engage the parking brake firmly, and utilize wheel chocks to prevent any unexpected movement. Ensure the transmission is securely set by pressing the P (Park) position switch on the shift lever or placing the vehicle in the N (Neutral) position as required by the specific task.
• If you are required to perform maintenance while the EV system is powered ON, keep your hands, clothing, hair, and all tools clear of radiator fans and any other automated moving parts that may engage without warning.
• Always ensure that the power switch is explicitly set to the OFF or LOCK position before commencing any repairs or part replacements.
• For your personal safety, remove any loose clothing and take off all jewelry, including rings, watches, and bracelets, before working under the hood.

  These items can inadvertently cause electrical shorts or become snagged on moving parts.

• Always wear approved industrial eye protection whenever you are working on your vehicle to guard against debris or chemical splashes.
• Never position yourself or any part of your body underneath the vehicle when it is supported solely by a jack. If work beneath the chassis is required, the vehicle must be supported by certified safety stands placed at the designated jacking points.
• Maintain a safe distance from the 12-volt battery, keeping all potential sources of flames, sparks, or intense heat away, as the battery may emit flammable hydrogen gas.

CAUTION

• Do not attempt to perform work under the hood while the motor compartment is hot. Always set the power switch to the OFF position and allow the system ample time to cool down completely before touching any components.
• Avoid direct skin contact with used coolant, as it can be harmful. If contact occurs, wash the affected area thoroughly with soap and water.

Improper disposal of engine coolant, brake fluid, or other automotive fluids poses a significant threat to the ecosystem. You must strictly adhere to all local, state, and federal environmental regulations regarding the responsible collection and disposal of all vehicle fluids.

NOTE:

In the event that the high-voltage battery is completely depleted, the transmission selector will be locked and cannot be manually shifted into different positions.
