WARNING
■Hybrid battery (traction 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 retailer or Lexus authoriz ed repairer, or any reliable repairer. Do not dispose of the battery yourself.
Unless the battery is properly collected, th e following may occur, resulting in death
or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is hazardous to
the environment or 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 generation, an explosion and elec- trolyte 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 Lexu s retailer or Lexus authorized repairer, or
any reliable repairer. If the hybrid battery is not disposed of properly, it may cause electric shock that can result in death or serious injury.
