Potential Hazards
Electrocution Risk
Always assume there is power to the system, even if you suspect the sensing system has disabled the high voltage battery.
Ensure the vehicle is disabled before performing extraction.
Potential Hazards
Please be aware of the following potential hazards, and always take the appropriate safety measures as outlined in your training and specified by your incident commander�s direction.
Personal Protection Equipment (PPE)
To ensure safety, wear Personal Protection Equipment (Insulation Gloves and Safety Glasses), and use HV insulated tools when working with the Kia Optima Hybrid.
Do not carry any metallic objects such as a watch or jewelry, as these can cause short circuits to occur. Always make sure that protective gear is not damaged and is free from any tears or moisture.
Flammable Fluids
Gasoline: 17.2 Gallons (65 liters)
Engine Oil: 4.76 Quarts (4.5 liters)
Automatic Transaxle Fluid: 6.87 Quarts (6.5 liters)
Undeployed Airbags and Pretensioners
The Kia Optima Hybrid is equipped with a driver�s front and side air bag, passenger�s front and side airbag, and curtain air bags.
To prevent accidental deployment of undeployed airbags, make sure the vehicle ignition switch is turned off, disconnect the negative cable from the 12V auxiliary battery, and recommended wait at least 3 minutes to allow the system to deactivate.
Unintended Airbag Deployment
To reduce the risk of injury during the 3-minute deactivation period, the following safety precautions are recommended:
Keep out of the path of an undeployed airbag. Refer to the above diagrams for the location of front, side and curtain airbags.
Do not cut into the center of the steering wheel or the dashboard where front airbags are stored.
Do not cut into the roof headliner where the curtain airbags are stored.
Be aware that extreme heat temperatures of 320-360� F (160-180� C) can cause unintended airbag inflation.
The Kia Optima Hybrid is equipped with driver�s and front passenger�s pretensioner seat belts.When the pretensioner seat belts are activated in a collision, a loud noise may be heard and fine dust, which may appear to be smoke, may be visible in the passenger compartment.These are normal operating conditions and are not hazardous. The pretensioner seat belt assembly mechanisms may become hot during activation, and may need several minutes to cool after they have been activated.
Electric Shock Potential
Electrocution Risk
The Kia Optima Hybrid uses a 270V DC voltage system. Unprotected contact with any electrically charged high-voltage component can cause serious injury or death.
To avoid electric shock potential, always wear Personal Protective Equipment including Safety Glasses and Insulating Gloves rated for 1,000V and above when handling High Voltage components or when removing the safety plug from the High Voltage Battery.
When the READY light is on and the EV MODE light is on, the electric motor is operational and the high voltage battery is supplying current to the high voltage system.
High Voltage Battery Electrolyte
The Kia Optima Hybrid High Voltage Battery Pack Assembly contains a pouch type, 270V lithium-ion polymer battery. In the event of high voltage battery electrolyte leakage, do not touch electrolyte.
12V Auxiliary Battery Electrolyte
The 12V auxiliary battery is located in the trunk of the vehicle, in the right side of the luggage compartment.
Electrolyte leakage hazards from the 12V auxiliary battery are the same as those in conventional passenger vehicles.
