discharge may occur.


If the hybrid system becomes difficult to start, have your vehicle checked
by your Lexus dealer or repairer, or another duly qualified and equipped
professional immediately.

If the "POWER" switch seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Con-
tact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional immediately.
