■ If the “READY” indicator does not come on
If the “READY” indicator does not come on when you press the “POWER”

Toyota dealer immediately.
■ When the “POWER” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your

■ Auto power OFF function
If the vehicle is left in ACCESSORY or ON mode (hybrid system is not oper-
ating) for more than an hour with the shift position in “P”, the “POWER”
switch will automatically turn OFF. However, this function cannot entirely pre-
vent battery discharge. Do not leave the vehicle with the “POWER” switch in
ACCESSORY or ON mode for long perio ds of time when the hybrid system
is not operating.
■ Operation of the “POWER” switch
● When operating the “POWER” switch, one short, firm press is enough. If
the switch is pressed improperly, the hybrid system may not start or the
“POWER” switch mode may not change. It is not necessary to press and
hold the switch.
● Even if the “POWER” switch is turned to off and then quickly re-pressed,
the “POWER” switch mode may not change. After turning the “POWER”
switch to off, wait for a short time before operating again.
