INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION

PRECAUTION (Continued)

4. ACTIONS TO BE TAKEN WHEN BATTERIES ARE DEPLETED
(a) Perform this procedure when the auxiliary battery is fully depleted.
HINT: The following problems indicate that the auxiliary battery is depleted:
- No display appears on the instrument panel when the power switch is ON (IG).
- The hybrid system does not start.
- The headlights are dim.
- The sound from the horn is weak.
NOTICE:
Never use a quick charger.
(1) Move the shift lever to the P position and engage the parking brake.
(2) Remove the key from the vehicle.




(3) Using a booster cable, connect the rescue vehicle's 12 V battery positive (+) lead to the stalled vehicle's relay block positive (+) terminal and the negative (-) lead to the suspension support's nut on the right side.
NOTICE:
Do not allow the booster cable to contact the seat vibration module assembly. The positive (+) terminal side of the auxiliary battery is close to the seat vibration module assembly. When charging the battery, it is extremely dangerous if the booster cable contacts the seat vibration module assembly, as sparks occur and the seat vibration module assembly may be damaged.
(4) Start the engine of the rescue vehicle and run the engine at a speed slightly higher than the idling speed for 5 minutes to charge the auxiliary battery of the stalled vehicle.




(5) Depress the brake pedal and push the power switch to start the hybrid system.
NOTICE:
If the hybrid system fails to start, the master warning light flashes, and the multi-information display is as shown in the illustration, the HV battery may be depleted.
(6) Disconnect the booster cable in the reverse order of the connection procedure.
NOTICE:
If the auxiliary battery needs to be replaced, replace it only with a 12 V battery specially designed for use with the LEXUS LS600h L.

(b) When the HV battery is depleted, replace the HV battery.




HINT: If the HV battery is depleted, the master warning light flashes, the multi-information display is as shown in the illustration, and DTC P3000-388, 389 or 603 is output.

5. ACTIONS TO BE TAKEN FOR VEHICLE DAMAGED BY IMPACT
(a) Items to be prepared for operation at the site of the accident.
- Protective clothing (insulated gloves, rubber gloves, goggles, and safety shoes)
- Saturated boric acid solution 20 L (obtain 800 g of boric acid powder, put it into a container, and dissolve it in water)
- Red litmus paper
- ABC fire extinguisher (effective against both oil flames and electrical flames)
- Shop rags (for wiping off electrolyte)
- Vinyl tape (for insulating cables)
- Electrical tester

(b) Actions to be taken at the accident site.
(1) Wear insulated or rubber gloves, goggles and safety shoes.
(2) Do not touch a bare cable that could be a high voltage cable. If the cable must be touched or if accidental contact is unavoidable, follow these instructions: 1) wear insulated or rubber gloves and goggles, 2) measure the voltage between the cable and the body ground using an electrical tester, and 3) insulate the cable using vinyl tape.
(3) If the vehicle catches on fire, use an ABC fire extinguisher to extinguish the fire. Trying to extinguish a fire using only a small amount of water can be more dangerous than effective. Use a substantial amount of water or wait for firefighters.
(4) Visually check the HV battery and immediate area for any electrolyte leakage. Do not touch any leaked liquid because it could be a highly alkaline electrolyte. Wear rubber gloves and goggles, and then apply red litmus paper to the leak. If the paper turns blue, the liquid must be neutralized before wiping. Neutralize the liquid using the following procedures: 1) apply saturated boric acid solution to the liquid, and 2) reapply red litmus paper and make sure it does not turn blue. Repeat steps 1 and 2 above until the paper does not turn blue. Then, wipe the neutralized liquid with a shop rag.
(5) If damage to any of the high-voltage components and cables is suspected, cut the high-voltage circuit using the procedure below.





1 Move the shift lever to the P position and engage the parking brake.
2 Remove the key from the vehicle. Then disconnect the cable from the negative (-) terminal of the auxiliary battery.
3 Remove the service plug while wearing insulated gloves.




CAUTION:
Do not turn the power switch ON (READY) while removing the service plug.




NOTICE:
If the service plug cannot be removed due to damage to the rear portion of the vehicle, remove the IGCT NO. 1 fuse from the engine room No. 1 relay block instead.

(c) Moving the damaged vehicle.
HINT: If any of the following applies, tow the vehicle away using a tow truck.
- One or more of the high-voltage components and cables are damaged.
- The driving, traction, or fuel system is damaged.





The READY light is not illuminated when you start the engine.
NOTICE:
- Tow the damaged vehicle with its front and rear wheels lifted off the ground. In an emergency where a tow truck is not available, the vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet. Also, make sure that the following conditions are met: 1) the towing should only be performed on paved roads for short distances at low speeds; 2) a driver must be in the vehicle to steer and operate the brakes; and 3) the vehicle's wheels, drive train, axles, steering and brakes must be operating normally.
- Before towing the vehicle away using a tow truck, disconnect the cable from the negative (-) terminal of the auxiliary battery and remove the service plug. Only if none of the above applies and there are no problems that might affect driving, drive the vehicle away from the accident site to a safe place nearby.
- Perform the procedure below if the READY light turns OFF, or there are abnormal noises, unusual smells, or strong vibrations while driving:
1 Park the vehicle in a safe place.
2 Move the shift lever to the P position and engage the parking brake.
3 Disconnect the cable from the negative (-) terminal of the auxiliary battery.
4 Remove the service plug while wearing insulated gloves.

(d) Actions required after moving the damaged vehicle. If you see any liquid on the road surface, it could be a highly alkaline electrolyte leakage.
Wear rubber gloves and goggles, and apply red litmus paper to the leak. If the paper turns blue, the liquid must be neutralized before wiping. Neutralize the liquid using the following procedures: 1) apply saturated boric acid solution to the liquid, and 2) reapply red litmus paper and make sure it does not turn blue. Repeat steps 1 and 2 above until the paper does not turn blue. Then wipe the neutralized liquid with a shop rag.
