◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating the tires.
● When the tire inflation pressure is changed such as when chang-
ing tire size. (When there are  multiple specified pressures)
● After registeri ng the ID codes. ( P. 429)
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set  as the benchmark pressure.
■How to initialize the tire pressure warning system
Park the vehicle in s afe place and turn the  engine switch off.
Initialization cannot be perfo rmed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 529)
Make  sure  to  adjust  the  tire  pre ssure  to  the  specified  cold  tire infla-
tion  pressure  level.  The  tire  pressure  warning  system  will  oper ate
based on this pr essure level.
Turn the engine switch to ON.
Push  and  hold  the  tire  pres-
sure  warning  reset  switch
until  the  tire  pressure  warn-
ing light blinks 3 times.
A message is displayed on the
multi-information  display. Also,
“-  -”  is  displayed  for  inflation
pressure of each tire on the
multi-information  display  while
the  tire  pressure  warning  sys-
tem determines the position.

The initialization operation
●Make sure to carry out initializ
ation after adjusting the tire inflation pres-
sure. 
Also, make sure the tires are co ld before carrying out initialization or tire
inflation pressure adjustment.
●If  you  have  accidentally  turned  the  engine  switch  to  OFF  during  initial-
ization, it is not necessary to press the reset switch again as  initialization
will restart automatically when the  engine switch has been turned to ON
for the next time.
●If you accidentally press the reset switch when initialization  is not neces-
sary,  adjust  the  tire  inflation  pressure  to  the  specified  level   when  the
tires are cold, and cond uct initialization again.
●While the position of each tire is being determined and the inf lation pres-
sures  are  not  being  displayed  on  the  multi-information  display,   if  the
inflation pressure of a tire drops, the tire pressure warning l ight will come
on.
■Warning performance of the tire pressure warning system
The  warning  of  the  tire  pressu re  warning  system  will  change  in  accor-
dance  with  the  conditions  under  which  it  was  initialized.  For  t his  reason,
the system may give a warning even if the tire pressure does no t reach a
low  enough  level,  or  if  the  pressure  is  higher  than  the  pressur e  that  was
adjusted to when the sys tem was initialized.
■When initialization of the tire  pressure warning system has fai led
Initialization  may  take  longer  to   complete  if  the  vehicle  is  driven  on  an
unpaved  road.  When  performing  ini tialization,  drive  on  a  paved road  if
possible. Depending on the driving environment and condition of  the tires,
initialization will be completed i n approximately 10 to 30 minutes. If initial-
ization is not complete after dr iving approximately 10 to 30 mi nutes, con-
tinue driving for a while.
If  the  inflation  pressure  of  each  tire  is  not  displayed  after  d riving  for
approximately 1 hour, perf orm the following procedure.
●Park  the  vehicle  in  a  safe  place  for  approximately  20  minutes. Then
drive  straight  (with  occasional  left  and  right  turns)  at  approx imately
25 mph (40 km/h) or more for approximately 10 to 30 minutes.
However, in the following  situatio ns, the tire inflation  pressure will  not  be
recorded  and  the  system  will  not  operate  properly.  Perform  initialization
again.
●When operating the tire pressure warning reset switch, the tire  pressure
warning light does  not blink 3 times.
●After  performing  initialization,  t he  tire  pressure  warning  light  blinks  for
1 minute then stays on while  driving about 20 minutes.
If the inflation pressure of eac h tire is still not displayed, have the vehicle
inspected by you r Toyota dealer.
