NOTICE
■ To prevent 12-volt battery discharge
● Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the hybrid system on.
●
If the hybrid system is off, but the indicator on the “POWER” switch is illu-
minated, this indicates that the “POWER” switch is still turned on. When
exiting the vehicle, always check that the “POWER” switch is off.
■ Symptoms indicating a malfunction with the “POWER” switch
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 your Toyota dealer immediately.
