3. Roadside Assistance Response Steps
• NEVER assume the LEAF is shut OFF simply because it is quiet.
• If the vehicle is damaged and you are not sure about the condition of the electric
vehicle system, contact first responders immediately. If the vehicle is damaged, the high
voltage system should be shut down by first responders while following the procedures in
the First Responders Guide and while wearing appropriate Personal Protective
Equipment (PPE) .
• If the READY indicator or charging indicator are ON, the high voltage system is
• If possible, be sure to verify that the READY indicator on the instrument cluster
OFF and the high voltage system is stopped.
• Some of the under hood parts get hot and may cause serious burns. Use caution when working on or around these parts.
3-1 Indications the High Voltage System is ON 1. If the READY indicator is ON, the high voltage system is active.
The high voltage system is active if any charge indicator
is ON (blue LEDs on top of the instrument panel) .
Before disconnecting the 12V battery terminal, if necessary, lower the windows, unlock the doors, and open

voltage system. Then verify whether the READY indicator is OFF.
If possible, keep the Nissan Intelligent Key® at least 5
meters (16 feet) away from the vehicle to prevent
accidentally turning ON the EV system while the
roadside assistance is in progress.
3-4 Water Submersion Damage level of submerged vehicle may not be apparent. Handling a submerged
without appropriate Personal Protective Equipment (PPE) will result in serious
injury or death from electrical shock. •
The power switch of the submerged vehicle must be turned OFF first, if possible. Then
vehicle must be completely out of the water and drained to avoid electrical shock.
• If the vehicle is in the water, to avoid electrical shock NEVER touch the high voltage
harnesses or service plug. PPE must always be worn when touching or
working on high voltage components.
Only first responders wearing appropriate Personal Protective Equipment (PPE) should shut down
the vehicle. After shut down, standard towing/recovery procedures can be used.
Refer to 4-3 Towing (RAG–22) . AAYIA0091ZZ

3-5 Vehicle Fire
• Always utilize full Personal Protective Equipment (PPE) and self-contained breathing
apparatus during fire fighting operations. Smoke from a LEAF vehicle fire is similar to
smoke from a conventional vehicle fire.
• In the case of extinguishing a fire with water, large amounts of water from a fire hydrant (if possible) must be used. DO NOT extinguish fire with a small amount of water. In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire
by wiring harnesses, electrical components, etc. or oil fire.
In case of vehicle fire, contact fire department immediately and extinguish the fire if possible. If you must
walk away from the vehicle, notify an appropriate responder or a rescue person of the fact that the vehicle is
an electric car and contains a high voltage system and warn all others.

3-6 Li-ion Battery Damage and Fluid Leaks
The Li-ion battery contains electrolyte solution. To avoid exposure to electrolyte solution
serious personal injury, always wear appropriate solvent resistant Personal Protective
Equipment (PPE) and read the following precautions:
• Electrolyte solution is a skin irritant.
• Electrolyte solution is an eye irritant – If contact with eyes, rinse with plenty of water and
see a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up the spilled electrolyte. Be sure to adequately ventilate the area.
• Electrolyte solution is highly flammable
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these cases,
rinse with plenty of water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
In cases of battery case breach or electrolyte leakage, contact the fire department immediately. If you must
walk away from the vehicle, notify an appropriate responder of the fact that the vehicle is an electric car and
contains a high voltage system and warn all others.
Li-ion Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the Li-ion battery is made up of many small sealed battery modules, electrolyte solutionleakage should be minimal.
Other fluids in the vehicle are the same as those in a conventional internal combustion

4. Roadside Assistance
To 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 12V battery explosion, resulting in severe
injury or death. It could also damage your vehicle.
Discharged 12V 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 Li-ion battery cannot be charged.
• The vehicle cannot be shifted out of PARK normally. • To avoid electrical shock, the high voltage Li-ion battery CANNOT be jump started.
Explosive hydrogen gas is always present in the vicinity of the 12V battery. Keep all
sparks and flames away from the 12V battery. Make sure the vent tube is correctly
• 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
• 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 12V 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 12V 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.
