●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 an other duly qualified and equipped profes- sional. 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 dispos ed 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 batterymust be disposed of by any authorized Lexu s dealer or repairer, or another duly qual-
ified 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.

WARNING
■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the safety of the area around the vehicle.
●Do not look continuously at the multi-info rmation display while driving as you may fail to see pedestrians, objects on the road, etc. ahead of the vehicle.
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information display. At extremely low temperatures, th e information display monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the dr iver’s shifting and the new gear number appearing on the display. This lag could cau se the driver to downshift again, causing rapid and excessive engine braking and po ssibly an accident resulting in death or
injury.
■Cautions during setting up the display
As the hybrid system needs to be running during setting up the display, ensure that the
vehicle is parked in a place with adequate ventilation. In a closed area such as a garage, exhaust gases including harmful carbon monoxide (CO) may collect and enter thevehicle. This may lead to death or a serious health hazard.
NOTICE
■While setting up the display
To prevent battery discharge, ensure that the engine is running while setting up the dis- play features.
