■ To operate the system properly
Make sure to carry the electronic key when operating the system. 
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The door lock prevention may not operate.)
■ Note for the smart key system
● Even when the electronic key is within the effective range (detection
areas), the system may not operate properly.
For example, the electronic key is on the instrument panel, luggage
cover, floor or in the door pockets or glove box when the hybrid system is
started or “POWER” switch modes are changed.
● Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.

PRIUS PHV_OM_OM47787U_(U)
■Operating the power wi ndows after turning the hybrid system off
The power windows can be operated for approximately 45 seconds even
after the “POWER” switch is tur ned to ACCESSORY mode or turned off.
They cannot, however, be operated once either front door is opened. 
■ Jam protection function
If an object becomes caught between the window and the window frame,
window travel is stopped and the window is opened slightly. 
■ When the power window does not close normally
If the jam protection function is operating abnormally and a window cannot
be closed, perform the following operations using the power window switch
on the relevant door.
● After stopping the vehicle, the window can be closed by holding the
power window switch in the one-touch closing position while the
“POWER” switch is turned to ON mode.
● If the window still cannot be closed even by carrying out the operation
explained above, initialize the function by performing the following proce-
dure. 
Hold the power window switch in the one-touch closing position.
Continue holding the switch for a further 6 seconds after the win-
dow has closed.
Hold the power window switch in the one-touch opening position.
Continue holding the switch for a further 2 seconds after the win-
dow has opened completely.
Hold the power window switch in the one-touch closing position
once again. Continue holding the switch for a further 2 seconds
after the window has closed.
If you release the switch while the window is moving, start again from the
beginning. 
If the window continues to close but then re-open slightly even after perform-
ing the above procedure correctly, have the vehicle inspected by your Toyota
dealer.

Immobilizer system
■System maintenance
The vehicle has a maintenance-free type immobilizer system.
■ Conditions aff ecting operation
Depending on the surrounding environment and conditions, the immobilizer
system may not operate properly. This may prevent the hybrid system from
starting. ( P. 119)
The  vehicle’s  keys  have  built-in  tr ansponder  chips  that  prevent  the
hybrid  system  from  starting  if  a  key  has  not  been  previously  regis-
tered in the vehicle’s  on-board computer. 
Never leave the keys inside the vehicle when you leave the vehicle.
The indicator light flashes after
the “POWER” switch has been
turned off to indicate that the
system is operating.
The indicator light stops flash-
ing after the “POWER” switch
has been turned to ACCES-
SORY or ON mode to indicate
that the system has been can-
celed.
