12.1.3. Maintenance precautions
When performing any inspection or maintenance work on your vehicle, always take care to prevent serious accidental injury to yourself or damage to the vehicle. The following are general precautions that should be closely observed.
The electric vehicle 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 voltage and the high temperature. Obey the labels that are attached to the vehicle.
Never disassemble, remove or replace high-voltage parts and cables as well as their connectors. High-voltage cables are coloured orange.
Disassembling, removing or replacing 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. Take your vehicle to a knowledgeable LEAF repairer such as a NISSAN certified electric vehicle dealer for any necessary maintenance.
Park the vehicle on a level surface, apply the parking brake securely and chock the wheels to prevent the vehicle from moving. Push the P position switch on the shift lever or place the vehicle into the N (Neutral) position.
If you must work while the electric vehicle system is turned on, keep hands, clothing, hair and tools away from moving fans and any other moving parts.
Make sure that the power switch is in the OFF or LOCK position when performing any part replacement or repair.
It is advisable to secure or remove any loose clothing and remove any jewellery, such as rings, watches, etc. before working on your vehicle.
Always wear eye protection whenever you work on your vehicle.
Do not get under a vehicle that is supported by a jack.
Keep smoking materials, flames and sparks away from the 12-volt battery.
Do not work under the bonnet while the motor compartment is hot. Place the power switch in the OFF position and wait until the motor compartment has cooled down.
Avoid direct contact with used coolant. Improperly disposed coolant and/or other vehicle fluids can damage the environment. Always conform to local regulations for the disposal of vehicle fluids.
Never connect or disconnect the 12-volt battery or any transistorised component while the power switch is in the ON position.
Your vehicle is equipped with an automatic cooling fan. It may activate 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 negative 12–volt battery cable before working near the fan.
