4. Jump Starting
T
o start the EV system with a booster battery, the instructions and precautions below must be followed. If done incorrectly, jump starting can lead to a 12-volt battery explosion, resulting in severe
personal
injury or death. It could also damage your vehicle.
Discharged 12-volt battery may cause the following issues: • The instrument cluster cannot be displayed while the power switch is turned ON. The start-upsound is not audible. (The electric car system cannot start.)
• The high-voltage battery cannot be charged.
• The vehicle cannot be shifted out of PARK normally. • To avoid electrical shock, the high-voltage battery CANNOT be jump started.
•
Explosive hydrogen gas is always present in the vicinity of the 12-volt battery. Keep all
sparks and flames away from the 12-volt battery. Make sure the vent tube is correctly
installed.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution that can cause severe burns.
If the fluid comes into contact with anything, immediately flush the contacted area
with water.
• The booster battery must be rated at 12 volts. Use of an improperly rated battery can damage the vehicle.
• Whenever working on or near a 12-volt battery, always wear suitable eye protectors (for example, goggles or industrial safety spectacles) and remove rings, metal bands,
or any other jewelry. Do not lean over the 12-volt battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• LEAF is equipped with an automatic cooling fan. It could come on at any time. Keep hands and other objects away from it.
• Always follow the jump starting instructions below. Failure to do so could result in damage to the charging system and cause personal injury. • Do not use LEAF to jump start another vehicle.
•
Do not attempt to perform a jump start on the 12-volt battery at the same time that the
high-voltage battery is being charged. Doing so may damage the vehicle or charging
equipment and could cause an injury.
