Countermeasures for Accidents or Fire
When an accident occurs while driving the electric vehicle, turn on the Hazard warning
light, move the vehicle to a safe place, and take following measures.
WARNING When a vehicle accident occurs and the high voltage battery is damaged, harmful gas
and electrolytes may leak.
• Be careful not to touch the leaked liquid.
• When you suspect leakage of inflammable gas and other harmful gases, open the windows and immediately evacuate to a safe location.
• If any leaked fluid comes in contact with your eyes or skin, immediately clean the affected area thoroughly with tap water or saline solution and have doctors inspect it
as soon as possible.

Turning Off the High Voltage Battery
In case disconnecting the high voltage cut-off switch is required in an emergency, follow
the instructions below.
WARNING • Do not intentionally disconnect the high voltage cut-off switch except in an emergency. The vehicle will not start if the high voltage battery is disconnected. Also,
when the switch is disconnected, dangerous accidents, such as electric shock, may
occur and various electric devices may be damaged.
• Do not touch any components inside the motor compartment with wet hands.
• Do not touch any components except for the components instructed to operate in this manual for a specific task.
• Do not touch wires exposed inside or outside the vehicle.
• Do not touch the high voltage electric wire (orange), connector, and all electric components and devices.

1. Open the hood and open the high voltage cut-off switch box on the right side of the motor compartment.
2. Pull the yellow label in the high voltage cut-off switch to shut down high voltage battery.
CAUTION Do not put excessive force to the switch lever while shutting down the high voltage
battery. Doing so may damage the high voltage cut-off switch.

If the Electric Vehicle Catches Fire
If a small scale fire occurs, use a fire extinguisher (ABC or BC) to extinguish the fire.
• If the fire cannot be extinguished early, evacuate to a safe place and do not let other people approach the site.
• Contact the fire department, report an electric vehicle fire, and then follow its instructions.
CAUTION • If you cannot put out the fire, immediately evacuate to a safe place and wait until the firefighters arrive.
• If the high voltage battery on the lower part of the vehicle catches fire, large amount of water must be supplied continuously for a long time to completely extinguish the fire.
It is hard to extinguish the fire without sufficient water and appropriate fire
extinguishers. If you approach the vehicle carelessly, it may cause accidents, such as
electric shock, and result in serious injury.

If the Electric Vehicle Is Submerged
If the electric vehicle is submerged while driving, immediately turn off the vehicle and
evacuate to a safe place. Contact the emergency rescue service such as a fire
department, or an authorized HYUNDAI dealer.
