For safety and security
■Alarm-operated door lock
In  the  following  cases,  depending  on  the  situations,  the  door  may  automati-
cally lock to prevent improper entry into the vehicle:
●When  a  person  left  in  the  vehicle  tr iggers  the  alarm  by  unlocking  a  door  or
the back door.
● When a person left in the vehicle unlocks a door or the back door while the
alarm is operating.

■Setting display automatic cancelation
In  the  following  situations,  setting  display  in  which  the  settings  can  be
changed through the “DISP” switch will automatically be turned off.
●If a warning message appears while the setting display is displayed
● When the vehicle begins to move while the setting display is displayed
■ Liquid crystal display
Small  spots  or  light  spots  may  appear  on  the  display.  This  phenomenon  is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.
WARNING
■The information display at low temperatures
Allow  the  interior  of  the  vehicle  to  warm  up  before  using  the  liquid  crystal
information display. At extremely low temperatures, the display monitor may
respond slowly, and display changes may be delayed. 
For  example,  there  is  a  lag  between  the  driver’s  shifting  and  the  new  gear
number  appearing  on  the  display.  This  lag  could  cause  the  driver  to  down-
shift  again,  causing  rapid  and  excessive  engine  braking  and  possibly  an
accident resulting in death or injury.
■ Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that
the  vehicle  is  parked  in  a  place  with  adequate  ventilation.  In  a  closed  area
such as a garage, exhaust gases including harmful carbon monoxide (CO)
may  collect  and  enter  the  vehicle.  This  may  lead  to  death  or  a  serious
health hazard.
NOTICE
■During setting up the display
To prevent battery discharge, ensure that the engine is running while setting
up the display features.

Operation of each component
■When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. ( P. 431)
On  vehicles  without  the  smart  key  system,  provide  the  attendant  with  the
valet key.
On  vehicles  with  the  smart  key  system,  remove  the  mechanical  key  for  your
own use and provide the attendant with the electronic key only.
■ If you lose your keys
New  genuine  keys  can  be  made  by  your  Toyota  dealer  using  a  master  key
(vehicles without a smart key system) or  the other key (vehicles with a smart
key  system)  and  the  key  number  stam ped  on  your  key  number  plate.  Keep
the plate in a safe place such as your wallet, not in the vehicle.
■ When riding in an aircraft
When  bringing  a  key  with  wireless  remote  control  function  onto  an  aircraft,
make  sure  you  do  not  press  any  buttons  on  the  key  while  inside  the  aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.
