CAUTION
Hybrid battery (traction battery)
Your vehicle contains a sealed nickel-metal hydride 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 any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in
death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and someone
may touch a high voltage part, resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified in
any way, accidents such as electric shock, heat generation, smoke genera-
tion, 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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional. If the
hybrid battery is not disposed of properly, it may cause electric shock that can
result in death or serious injury.
