Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Procedures At An Accident Scene
- Preparation items
Protective equipment (insulated gloves, rubber gloves, protective goggles, and rubber boots for electrical purposes)
Saturated boric-acid solution 20 L (In a container, dissolve 800 g of boric acid powder purchased at a drug store in 20 L of water.)
Red litmus paper (purchase at a drug store)
Fire extinguisher (used for both oil fire and electric fire)
Cloth, old towels (for wiping electrolytic solution)
Insulating tape
Circuit tester
- Procedures at an accident scene
Do not touch the exposed wires, when whether they are high voltage wires or not is unknown. When it is necessary or possible to touch them, make sure to wear insulated gloves and insulate the wires using insulating tape.
When vehicle is on fire, extinguish a fire using an electrical fire extinguisher. Attempting to extinguish a fire with a small amount of water may be more of a danger. Therefore, spray a large amount of water from a fire hydrant, or wait for arrival of firefighters.
When the vehicle is submerged in water, do not touch the service disconnect plug and any other high voltage parts and wires due to a possibility of electrical shock. Perform work after completely pulling out the vehicle.
- Check for any leakage in the high voltage battery vicinity.
CAUTION:- Do not touch any leaked fluid, because it may be strong alkaline electrolytic solution. When it is necessary to touch it, wear insulated gloves and protective goggles, neutralize with saturated boric-acid solution, confirm that red litmus paper does not change to blue, and then wipe off with cloth.
- Do not touch the skin or eyes with rubber gloves with the electrolytic solution (strong alkaline) adhered, because it may cause inflammation and blindness.
- When the vehicle is damaged due to collision, stop the hybrid system in the following steps.
- Turn the ignition to OFF.NOTE: When the ignition cannot be turned to OFF, remove the fuse in engine compartment.
- Wear insulated gloves and remove the service disconnect plug. < Ref. to SERVICE DISCONNECT PLUG REMOVAL , CAUTION (HYBRID SYSTEM), Precaution.>

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
