HOW TO HANDLE THE DAMAGED VEHICLES AT AN ACCIDENT SCENE

High voltage system shut-down procedure
Shut down the high voltage system according to vehicle damage level. Any of the following procedures can shut down the high voltage system. The first response operation should be done after shutting down the high voltage system.
If the vehicle is heavily damaged, for example the Li-ion battery is deformed, broken or cracked, appropriate
PPE must be used and the Li-ion battery and high voltage components must not be touched.
DANGER:


-Failure to properly shut down the high voltage system before the Emergency Response Procedures are performed may result in serious injury or death from electrical shock. To prevent from serious injury or death, DO NOT touch high voltage harnesses or components with bare hands.
-When contact with high voltage components or high voltage harnesses is unavoidable, or when there is risk of such contact, be sure to wear appropriate PPE.

WARNING:
-If the charge connector is connected to the vehicle, remove it. Refer to Removing the Charge
Connector.
-The vehicle contains parts that contain powerful magnets. If a person who is wearing a pacemaker or other medical device is close to these parts, the medical device may be affected by the magnets. Such persons must not perform work on the vehicle.
- Be sure to check the READY indicator in the instrument cluster, and verify that the READY indicator is off and the high voltage system is stopped.
- There is a possibility of remaining high voltage in the air conditioning system by the remote air conditioning system. If the READY indicator is turned OFF and the air conditioning remote timer indicator is turned ON the high voltage system is active. Please ensure that the air conditioning remote timer indicator is turned OFF and the air conditioning system is inactive.
- After high voltage system shut-down, please wait for 10 minutes for complete discharge of the high voltage condenser. While waiting, do not operate any vehicle functions.
- The high voltage full discharge takes 10 minute, but after 5 minutes the voltage has dropped below
60 V.
- Remove the 12V battery negative terminal and wait for 3 minutes to discharge the air bag condenser.
Even though the 12V battery negative is disconnected, the Supplemental Restraint System (SRS) air bag maintains voltage for 3 minutes. There is a possibility of sudden SRS air bag inflation due to harness short circuit or damage and it may cause serious injuries.





1.If the READY indicator is ON, the high voltage system is active.
2.If the charge indicator is ON, the high voltage system is active.
3.If the air conditioning remote timer indicator (located on the HVAC controller) is ON, the high voltage system is active.
4.If the remote controlled air conditioning system is active, push the power switch to the ON position. This will turn OFF the remote controlled air conditioning system.
NOTE:
Remote controlled air conditioning system is a feature that allows the vehicle owner to activate the air conditioning system via telematics communication (cell phone, personal computer, etc.). When this system is active, the air conditioning remote timer indicator (located on the HVAC controller) is illuminated.
Before disconnecting the 12V battery terminal, if necessary, set the parking brake, lower the windows, unlock the doors, and open the rear hatch as required. Once 12V battery is disconnected, power controls will not operate.
Procedure 1: Turning OFF the Power Switch.
1.Check the READY indicator status. If it is ON, the high voltage system is active.
2.Press the power switch once to turn OFF the high voltage system. Then verify whether the READY indicator is OFF.
3.If possible, keep the intelligent key at least 5 meters (16 feet) away from the vehicle.
4.Open the hood.
5.Disconnect the negative 12V battery cable. Insulate the negative 12V battery cable terminal with insulated tape.
6.Wait 10 minutes for complete discharge of the high voltage condenser after the power switch has been turned OFF and the battery cable has been disconnected.
7.Perform the first response action.
Procedure B: Removing Fuses Under Hood
1.Open the hood.
2.Press and expand the pawls on the sides of the fuse box and remove the fuse box from its housing.
3.Remove the following fuses:
-VCM ING fuse (F15 VCM IGN 10A)
-PBW Fuse (F21 PBW IGN 15A)
-VCM Fuse (F3 VCM 20A)
4.If you cannot identify the above fuses, remove all fuse in the fuse box.
5.Disconnect the negative 12V battery cable. Insulate the negative 12V battery cable terminal with insulated tape.
6.Wait 10 minutes for complete discharge of the high voltage condenser after the fuses and pulled and battery cable has been disconnected.
7.Perform the first response action.

WARNING:


To avoid unintended installation and risk of electrical shock, the rescuer should carry the fuses on his/her person and cover the fuse box with insulated tape.
Procedure C: Removing the Service Plug
DANGER:


-Do not remove the service plug without wearing appropriate PPE to help protect the responder from any serious injury or death by electrical shock.
-Immediately cover the service plug socket with insulated tape. To avoid electric shock, DO NOT
touch the terminals inside the socket.

WARNING:


To avoid unintended installation and risk of electrical shock, the rescuer should carry the service plug on his/her person while work is in progress.





1.Locate the carpet flap (1) behind center console on the floor raised area. At the notched area (A) pull up on the carpet flap (1).






2.Remove the access cover bolts (A) and remove the cover (1).

3.Remove the service plug by pressing the locking tab (1) and rotating the handle (2) upward. Using the handle, pull the service plug completely out of its socket.





4.Wait 10 minutes for complete discharge of the high voltage condenser after the service plug has been removed.
5.Open the hood.
6.Disconnect the negative 12 V battery cable. Insulate the negative 12V battery cable terminal with insulated tape.
7.Wait 3 minutes for complete discharge of the air bag condenser after the battery cable has been disconnected.
8.Perform the first response action.

VEHICLE FIRE


WARNING:
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. Small amounts of water will make toxic gas produced by a chemical reaction between the Li-ion battery electrolyte and water.

CAUTION:
In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire caused 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 thet the vehicle is an electric car and contains a high voltage system and warm all others.

LI-ION BATTERY DAMAGE AND FLUID LEAKS

- Clear in color
- Sweet odor
- Similar viscosity to water
- Skin irritant
- Eye irritant - If contact with plenty of water and see a doctor immediately.
- 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.
- Since the Li-ion battery is made up of many small sealed battery modules, electrolyte solution should not leak in large quantity.
NOTE:
Other fluids in the vehicle (such as washer fluid, brake fluid, coolant, etc.) are the same as those in a conventional internal combustion vehicle.
