■ The initialization operation 
● Make sure to carry out initialization after adjusting the tire inflation pressure. 
Also,  make  sure  the  tires  are  cold  before  carrying  out  initiali zation  or  tire 
inflation pressure adjustment. 
● If you have accidentally turned the power switch off during initialization, it is 
not  necessary  to  press  the  reset  switch  again  as  initialization   will  restart 
automatically  when  the  power  switch  has  been  turned  to  ON  mode  for  the 
next time.  
● If you accidentally press the reset switch when initialization is not necessary, 
adjust  the  tire  inflation  pressure  to  the  specified  level  when  the  tires  are 
cold, and conduct initialization again. 
■ Warning performance of the tire pressure warning system 
The  warning  of  the  tire  pressure  warning  system  will  change  in  accordance 
with the conditions under which it was initialized. For this re ason, the system 
may  give  a  warning  even  if  the  tire  pressure  does  not  reach  a  l ow  enough 
level, or if the pressure is higher than the pressure that was  adjusted to when 
the system was initialized. 
■ When initialization of the tire pressure warning system has failed 
Initialization  can  be  completed  in  a  few  minutes.  However,  in  t he  following 
cases,  the  settings  have  not  been  recorded  and  the  system  will  not  operate 
properly.  If  repeated  attempts  to  record  tire  inflation  pressur e  settings  are 
unsuccessful, have the vehicle inspected by any authorized Toyo ta retailer or 
Toyota authorized repairer, or any reliable repairer as soon as  possible. 
● When  operating  the  initialization  of  the  system,  the  tire  pressure  warning 
light does not flash 3 times and the setting message does not a ppear on the 
multi-information display. 
● After  driving  for  a  certain  period  of  time  since  the  initialization  has  been 
completed, the warning light comes on after blinking for 1 minu te. 
■ Registering ID codes 
The ID codes of the tire pressure warning valve and transmitter s for two sets 
of wheels can be registered.  
It  is  not  necessary  to  register  the  ID  codes  when  replacing  nor mal  tires  with 
snow tires, if the ID codes for the wheels of both normal tires  and snow tires 
are registered beforehand.  
For  information  about changing  ID  codes,  ask  any  authorized Toy ota  retailer 
or Toyota authorized repairer, or any reliable repairer.
