Conditions affecting operation
The smart key system uses weak radio waves. In the following si tuations, the
communication  between  the  electronic  key  and  the  vehicle  may  be   affected,
preventing  the  smart  key  system,  wireless  remote  control  and  immobilizer
system from operating properly. (Ways of coping:  P. 517)
● When the electronic key battery is depleted
● Near  a  TV  tower,  electric  power  plant,  gas  station,  radio  stati on,  large  dis-
play,  airport  or  other  facility  that  generates  strong  radio  wav es  or  electrical
noise
● When  the  electronic  key  is  in  contact  with,  or  is  covered  by  the  following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When other wireless keys (that emit radio waves) are being used nearby
● When  carrying  the  electronic  key  together  with  the  following  devices  that
emit radio waves
• A  portable  radio,  cellular  phone,  cordless  phone  or  other  wire less  com-
munication device
• Another vehicle’s electronic key or a wireless key that emits  radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If  window  tint  with  a  metallic  content  or  metallic  objects  are  attached  to  the
rear window
● When  the  electronic  key  is  placed  near  a  battery  charger  or  ele ctronic
devices

Notes for the entry function
●Even when the electronic key is within the effective range (det ection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door  handle, near
the ground, or in a high place when the doors are locked or unl ocked.
• The  electronic  key  is  on  the  instrument  panel,  luggage  cover  o r  floor,  in
the door pockets or glove box when the hybrid system is started  or power
switch modes are changed.
● Do  not  exit  the  vehicle  with  the  electronic  key  placed  on  the  i nstrument
panel or near the door pockets. Depending on the radio wave reception con-
ditions,  it  may  be  detected  by  the  antenna  outside  the  cabin  and  the  door
will  become  lockable  from  the  outside,  possibly  trapping  the  electronic  key
inside the vehicle.
● As long as the electronic key is within the effective range, th e doors may be
locked or unlocked by anyone. However, only the doors detecting  the elec-
tronic key can be used to unlock the vehicle.
● Whether  or  not  the  electronic  key  is  inside  the  vehicle,  the  hy brid  system
could be started if the electronic key is near the window.
● The doors may unlock if a large amount of water splashes on the  door han-
dle, such as in the rain or in a car wash when the electronic k ey is within the
effective  range.  (The  door  will  automatically  be  locked  after  a pproximately
60 seconds if the doors are not opened and closed.)
● The  lock  and  unlock  sensors  may  not  work  properly  if  they  come  into  con-
tact  with  ice,  snow,  mud,  etc.  Clean  the  sensors  and  attempt  to  operate
them again.
● If  the  wireless  remote  control  is  used  to  lock  the  doors  when  t he  electronic
key  is  near  the  vehicle,  there  is  a  possibility  that  the  door  m ay  not  be
unlocked by the entry function. (Using the wireless remote cont rol to unlock
the doors may resume the function.)
● If the  door  handle becomes  wet while the  electronic  key  is with in the  effec-
tive range, the door may lock and unlock repeatedly. In that ca se, follow the
following correction procedures to wash the vehicle:
• Place  the  electronic  key  in  a  location  6  ft.  (2  m)  or  more  awa y  from  the
vehicle. (Take care to ensure that the key is not stolen.)
• Set  the  electronic  key  to  battery-saving  mode  to  disable  the  s mart  key
system. ( P. 140)

Notes for locking the doors
●Touching  the  door  lock  sensor  while  wearing  gloves  may  delay  or  prevent
lock operation. Remove the gloves and touch the lock sensor aga in.
● When the lock operation is performed using the lock sensor, rec ognition sig-
nals  will  be  shown  up  to  two  consecutive  times. After  this,  no  recognition
signals will be given. 
● If  the  electronic  key  is  inside  the  vehicle  and  a  door  handle  b ecomes  wet
during  a  car  wash,  a  buzzer  will  sound  outside  the  vehicle.  To  turn off the
alarm, lock all the doors.
■ Notes for the un locking function
● A  sudden  approach  to  the  effective  range  or  door  handle  may  prevent  the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the  door handle
again.
● Gripping  the  door  handle  when  wearing  a  glove  may  not  unlock  th e  door.
Remove the gloves and touch the sensor on the back of the handle again.
● If  there  is  another  electronic  key  in  the  detection  area,  it  ma y  take  slightly
longer to unlock the doors after the door handle is gripped. 
■ When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic ke y within 6 ft. (2
m) of the vehicle.
● The  smart  key  system  can  be  deactivated  in  advance.  Ask  your  To yota
dealer for details.
■ To operate the smart key system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the  system from the
outside of the vehicle.
Depending on the position and holding condition of the electron ic key, the key
may not be detected correctly and the system may not operate pr operly. (The
alarm  may  go  off  accidentally,  or  the  door  lock  prevention  func tion  may  not
operate.)
■ If the smart key system does not operate properly
●Locking and unlocking the doors: Use the mechanical key. ( P. 517)
● Starting the hybrid system: P. 517
■ If the smart key system has been d eactivated in a customized setting
● Locking  and  unlocking  the  doors:  Use  the  wireless  remote  contro l  or
mechanical key. ( P. 126, 517)
● Starting the hybrid system and changing power switch modes: 
P. 517
● Stopping the hybrid system:  P. 191
■ Customization
Settings (e.g. operation signals) can be changed.

WARNING
■Caution regarding interfer ence with electronic devices
● People  with  implantable  cardiac  pacemakers,  cardiac  resynchroni zation
therapy-pacemakers or implantable cardioverter defibrillators s hould keep
away from the smart key system antennas. ( P. 139)
The  radio  waves  may  affect  the  operation  of  such  devices.  If  ne cessary,
the entry function can be disabled. Ask your Toyota dealer for  details, such
as  the  frequency  of  radio  waves  and  timing  of  the  emitted  radio   waves.
Then, consult your doctor to see if you should disable the entr y function.
● User of any electrical medical device other than implantable ca rdiac pace-
makers,  cardiac  resynchronization  therapy-pacemakers  or  implant able
cardioverter defibrillators should consult the manufacturer of  the device for
information about its operation under the influence of radio wa ves.
Radio  waves  could  have  unexpected  effects  on  the  operation  of  such
medical devices.
Ask your Toyota dealer for details for disabling the entry func tion.

WARNING
■When adjusting the seat position
● Take  care  when  adjusting  the  seat  position  to  ensure  that  other  passen-
gers are not injured by the moving seat.
● Do  not  put  your  hands  under  the  seat  or  near  the  moving  parts  t o  avoid
injury.
Fingers or hands may become jammed in the seat mechanism.
● Make sure to leave enough space around the feet so they do not  get stuck.
■ Seat adjustment
● Be careful that the seat does not hit passengers or luggage.
● To  reduce  the  risk  of  sliding  under  the  lap  belt  during  a  colli sion,  do  not
recline the seat more than necessary .
If  the  seat  is  too  reclined,  the  lap  belt  may  slide  past  the  hi ps  and  apply
restraint  forces  directly  to  the  abdomen,  or  your  neck  may  cont act  the
shoulder belt, increasing  the risk of death  or  serious  injury i n the  event of
an accident.
Adjustmen ts should not be made while driving as the seat may un expect-
edly move and cause the driver to lose control of the vehicle.
● After adjusting the seat, make sure that the seat is locked in position.
