91 1-4. Hybrid system 1 For safety and security WARNING ● If electrolyte is leaking from the hybrid battery (traction battery), do not approach the vehicle. Even in the unlikely event that the hybrid battery (traction battery) is damaged, the internal construction of the battery will prevent a large amount of electrolyte from leaking out. How- ever, any electrolyte that does leak out will give off a vapor. This vapor is an irritant to skin and eyes and could cause acute poisoning if inhaled. ● Do not bring burning or high-tem- perature items close to the electrolyte. The electrolyte may ignite and cause a fire. ● If a fire occurs in the hybrid electric vehicle, leave the vehicle as soon as possible. Never use a fire extinguisher that is not meant for electric fires. Using even a small amount of water may be dangerous. ● If your vehicle needs to be towed, do so with rear wheels raised. If the wheels connected to the electric motor (traction motor) are on the ground when towing, the motor may continue to generate electricity. This may cause a fire. ( P.379) ● Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto the ground, the fuel sys- tem may have been damaged. Leave the vehicle as soon as possible. ■ Hybrid battery (traction battery) ● Your vehicle contains a sealed lithium- ion battery ● Never resell, hand over or modify the hybrid battery. To prevent accidents, hybrid batteries that have been removed from a disposed vehicle are collected through Lexus dealer. Do not dispose of the battery yourself. Unless the battery is properly col- lected, the following may occur, result- ing in death or serious injury: • The hybrid battery may be illegally dis- posed of or dumped, and it is hazard- ous to the environment or someone may touch a high voltage part, result- ing in an electric shock. • The hybrid battery is intended to be used exclusively with your hybrid elec- tric vehicle. If the hybrid battery is used outside of your vehicle or modified in any way, accidents such as electric shock, heat generation, smoke gener- ation, an explosion and electrolyte leakage may occur. When reselling or handing over your vehicle, the possibility of an accident is extremely high because the person receiving the vehicle may not be aware of these dangers. ● If your vehicle is disposed of without the hybrid battery having been removed, there is a danger of serious electric shock if high voltage parts, cables and their connectors are touched. In the event that your vehicle must be disposed of, the hybrid battery must be disposed of by your Lexus dealer or a qualified service shop. If the hybrid battery is not disposed of prop- erly, it may cause electric shock that can result in death or serious injury. NOTICE ■ Hybrid battery (traction battery) Do not carry large amounts of water such as water cooler bottles in the vehi- cle. If water spills onto the hybrid battery (traction battery), the battery may be damaged. Have the vehicle inspected by your Lexus dealer.

Hybrid system There are air intake vents under the When a certain level of impact is A message is automatically displayed Hybrid battery (traction battery) NOTICE ■ Hybrid battery (traction battery) air intake vents ● Make sure not to block the air intake vent with anything, such as a seat cover, plastic cover, or luggage. If the vents become blocked, the hybrid bat- tery (traction battery) input and output may be restricted, leading to a reduc- tion in hybrid battery (traction battery) output and a malfunction. ● When dust etc. has accumulated in the air intake vent, periodically clean it with a vacuum cleaner to prevent the vent from clogging. ● Filters are installed to the air intake vent. When the filters remain notice- ably dirty even after cleaning the air intake vent, filter cleaning or replace- ment is recommended. When clean- ing or replacing the filters, contact your Lexus dealer. Refer to P.324 for details on how to clean the filters. ● Do not get water or foreign materials in the air intake vents as this may cause a short circuit and damage the hybrid battery (traction battery).
