If the Main drive lithium-ion battery is severely damaged, the Main drive lithium-ion battery must be discharged by soaking in water prior to any dismantling work in order to reduce the risk of electric shock and/or fire. If one of the following conditions is observed, the battery is likely severely damaged: - Organic solvent odor is detected around the vehicle that is unlike gasoline, light oil or oil odors. - Inner components such as batteries or electric wirings are visible through an opening in the damaged Main drive lithium-ion battery case. - An object is penetrating into the Main drive lithium-ion battery case. - Driver's, front passenger's, and/or the rear seat is deformed or tilted due to floor deformation. WARNING;  Wear Personal Protection Equipment when checking for damage to the Main drive lithiumion battery.  If the Main drive lithium-ion battery is severely damaged, even after the high voltage circuit has been shut off, there is still a risk of electrical shock and/or fire.  If it is not possible to proceed immediately with the process for discharging the Main drive lithium-ion battery, place the vehicle in an open space away from any structure or vehicle, and continue to monitor the vehicle until the discharging process has been completed and the risk of fire is eliminated.  If you detect leaking fluids, sparks, smokes, flames, increased temperature, gurgling, popping, or hissing noises from the HV compartment, notify the Fire Department. Ensure area is clear around the vehicle. If possible, open windows to avoid potential gas build-up. 9 Step 2A: Shutting Off the High Voltage WARNING; If the Main drive lithium-ion battery is severely damaged, do not carry out the procedures described in this section. Instead, discharge the Main drive lithium-ion battery in accordance with Step 2B. 1) Shut down the vehicle’s high voltage system using one of the following two methods. This will disconnect the high voltage electricity current supplied from the Main drive lithium-ion battery. ① Turn the Electric Motor Switch (Ignition switch) on the steering column to the “LOCK” position. ② If it is impossible to turn off the electric motor switch, use needle-nose pliers to remove the Power control unit fuse from the fuse box under the hood. It is the No.7 15A fuse shown in the figure below. If you cannot locate this fuse, remove all fuses and relays in the fuse box. The hood release is under the instrument panel beside the front passenger’s door. Pull Fuse No. 7 10 2) Wait at least 1 minute before proceeding to the next step. High voltage system shut down is performed during this waiting time. 3) Disconnect the 12V battery negative terminal. This will disconnect the power supply to the SRS airbag system and the EV ECU. Disconnect the 12V battery negative terminal by using a 10mm wrench as follows: ① Remove the cover of the 12V battery under the hood. Turn the plastic nut (A) counter clockwise, and then remove the battery upper cover (B). ② Disconnect the negative terminal from the 12V battery. 4) If necessary, cut the negative 12V battery cable, then wrap electrical tape to insulate the cable ends. WARNING; After disconnecting the 12V battery negative terminal, to avoid the risk of inadvertent air bag deployment, wait at least 1 minute. The SRS air bag system is designed to retain enough voltage to deploy the air bag for a short time even after the 12V battery has been disconnected. 5) Wait at least 5 minutes before proceeding to the next step. Working with the High voltage circuit in the Main drive lithium-ion battery can be performed about 5 minutes after disconnecting the 12V battery negative terminal. 6) Remove the Service Plug by following the procedure below. WARNING;  Always wear Personal Protective Equipment (PPE) when removing the Service Plug.  If the Service Plug is removed without following the procedure described in this section, a short circuit can occur and melted metal debris may fly from the service plug terminal, resulting in injury to dismantlers. ① Adjust the front left side seat to its rear most position and roll up the carpet under the seat. Detach the service lid by removing two wing nuts. If it is difficult to move the seat, remove it. 11 ② Pull up the lever of the Service Plug and then remove the Service Plug by pulling upward on the lever. WARNING;  After removing the Service Plug, keep it in a secure place away from other dismantlers to prevent accidental handling/improper re-installation.  There are some high voltage components and wiring cables which retain high voltage for 5 minutes after disconnecting the 12V battery. When it is necessary to cut the high voltage components and wiring cables, wait at least 5 minutes after cutting before commencing the next action. at 7) Measurement of the Main drive lithium-ion battery's voltage WARNING; Always wear eye protection (safety glasses) to protect your eyes from flying debris. ① Remove the undercover for the Main drive lithium-ion battery 12 ② Remove the service hole lids on the bottom of the Main drive lithium-ion battery and carry out the measurement of the battery’s voltage as shown below.

When the high voltage circuit is successfully shut down, the voltage shows 0V. 13 Step 2B: Discharging the Main Drive Lithium-ion Battery WARNING; - Do not use salt water to discharge the Main drive lithium-ion battery. Using water containing salt can generate a large volume of flammable hydrogen and increases the risk of fire or explosion. - Hydrogen gas is generated during the discharging process, even when fresh water is used and proper discharging procedures are followed. To reduce the risk of fire; ● The discharging must be done in a well-ventilated area located outside. ● Keep all windows, doors and the tailgate open to prevent hydrogen from accumulating in the passenger compartment. - Do not remove the vehicle from the water for 72 hours in order to discharge the battery completely. 1) Soaking the vehicle in water Marked ★ items are required. The other items should be available and used as necessary. Step 1. Set up an easy set pool in the size of approximately 450cm X 200cm X 70cm [approximately 180 inch X 80 inch X 30 inch] (length X width X height). Step 2. Use a forklift or similar equipment to place the vehicle in the center of the pool. Step 3. ★Open all windows, doors and the tailgate. Step 4. ★Make sure to use water that does not contain salt (use tap water, well water or pond water) to prevent an aggressive chemical reaction and the excessive release of flammable hydrogen gas.  ★Required water level: Fill the pool with water until a minimum required depth of 50cm [20 inch] is achieved. Front and Rear tire height is about 50cm [20 inch]. (See illustration below.) This water level is considered deep enough for the Main drive lithium-ion battery to be completely submerged in water. If the vehicle body is significantly deformed due to impact from a crash, make sure that the Main drive lithium-ion battery installed under the floor is completely submerged in water. Add additional water if necessary. ★Maintain this water level for at least 72 hours with the Main drive lithium-ion battery soaking in water. Illustration: Required Water Level Front and rear tire should be located under water. 14 2) Draining the Main drive lithium-ion battery Step 1.
