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 Lexus dealer. 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 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 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 properly, it may cause electric shock
that can result in death or serious injury.

CAUTION
■The multi-information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal multi-
information display. At extremely low temperatures, the multi-information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cause the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
■Cautions during setting up the display
As the engine 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 car-
bon monoxide (CO) may collect and enter the vehicle. This may lead to death or a
serious health hazard.
NOTICE
■During setting up the display
To prevent 12-volt battery discharge, ensure that the engine is running tem is operating> while setting up the display features.
