Maintenance and care
●Performance may be affected in the following situations.
• When driving near a TV tower, electric power plant, gas station, radio
station,  large  display,  airport or  other  facility  that  generates  strong
radio waves or electrical noise
• When  carrying  a  portable  radio,  cellular  phone,  cordless  phone or
other wireless communication device
If  tire  position  information  is  not  correctly  displayed  due  to the  radio
wave conditions, the display may be corrected by changing the location
of the vehicle as the radio wave conditions may change.
●When  the  vehicle  is  stopped,  the  time  taken  for  the  warning  to start  or
turn off may be longer.
●When  the  inflation  pressure  of  a  tire  drops  rapidly,  for  example  when  a
tire has burst, the warning may not operate.
■Initialization procedure
●Make sure  to perform the  initialization procedure after adjusting the tire
inflation pressure.
Also,  make  sure  the  tires  are  cold  before  performing  the  initialization
procedure or adjusting the tire inflation pressure.
●If  the  engine  switch  is  turned  off  during  initialization,  it  is  not  necessary
to  restart  the  initialization  procedure  from  the  beginning  as  it  will  begin
automatically  when  the  engine  switch  is  turned  back  to  IGNITION ON
mode.
●If  initialization  has  accidentally  been  started  when  it  is  not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold and then perform the initialization procedure again.
●While the position of each tire is being determined and the inflation pres-
sures  are  not  being  displayed  on  the  multi-information  display,  if  the
inflation pressure of a tire drops, the tire pressure warning light will come
on.
■Warning performance of the tire pressure warning system
The  warning  of  the  tire  pressure  warning  system  will  change  in accor-
dance  with  the  conditions  under  which  it  was  initialized.  For  this  reason,
the system may give a warning even if the tire pressure does not reach a
low  enough  level,  or  if  the  pressure  is  higher  than  the  pressure  that  was
adjusted to when the system was initialized.

■If the tire pressure warning system is not initialized properly
●In the following situations, initialization may take longer than usual to be
completed  or  may  not  be  possible.  (Usually,  the  vehicle  will  need  to  be
driven for approximately 10 to 30 minutes to complete initialization.) 
If  initialization  is  not  complete  after  driving  approximately  30  minutes,
continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer to com-
plete initialization.
• If  the  vehicle  is  backed  up  while  performing  initialization,  data  col-
lected  during  initialization will  be  cleared  and  it  will  take  longer  than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other
vehicles are driven close by, it may take time for the system to recog-
nize  the  tire  pressure  warning  valve  and  transmitters  of  your  vehicle
over those of other vehicles.
If  initialization  is  not  complete  after  driving  for  approximately 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
drive the vehicle again.
●In  the  following  situations,  initialization  will  not  be  started or was not
completed  properly  and  the  system  will  not  operate  properly.  Perform
the initialization procedure again.
• If, when attempting to start initialization, the tire pressure warning light
does not blink 3 times.
• If,  when  the  vehicle  has  been  driven  for  about  20  minutes  after  per-
forming initialization, the tire pressure warning light blinks for approxi-
mately 1 minute and then illuminates.
●If  initialization  cannot  be  completed  after  performing  the  above  proce-
dure, contact your Toyota dealer.

Maintenance and care
■When registering ID codes
●Before  performing  ID  code  registration,  make  sure  that  no  wheels  with
tire pressure warning valve and transmitters installed are near the vehi-
cle.
●Make sure to initialize the tire pressure warning system after registering
the ID codes. If the system is initialized before registering the ID codes,
the initialized values will be invalid.
●As  the  tires  will  be  warm  when  registration  is  completed,  make sure  to
allow the tires to cool before performing initialization.
■Canceling ID code registration
●To cancel ID code  registration  after  it has been started, turn the engine
switch off before driving the vehicle.
If the vehicle is driven after ID code registration is started, to cancel reg-
istration, perform the ID code registration start procedure again and turn
the engine switch off before driving.
●If ID code registration has been canceled, the tire pressure warning light
will blink for approximately 1 minute when the engine switch is turned to
IGNITION ON mode and then illuminate. The tire pressure warning sys-
tem will be operational when the tire pressure warning light turns off.
●If  the  warning  light  does  not  turn  off  even  after  several  minutes  have
elapsed, ID code registration may not have been cancelled correctly. To
cancel  registration,  perform  the ID  code  registration  start  procedure
again and then turn the engine switch off before driving.

■If ID codes are not registered properly
●In  the  following  situations,  ID  code  registration  may  take  longer  than
usual to be completed or may not be possible. (Usually, the vehicle will
need  to  be  driven  for  approximately  10  to  30  minutes  to  complete  ID
code registration.) 
If ID code registration is not complete after driving for approximately 30
minutes, continue driving for a while.
• If  the  vehicle  is  driven  on  an  unpaved  road,  it  may  take  longer  than
normal to complete registration.
• If  the  vehicle  is  backed  up  while  performing  registration,  data  col-
lected  during  registration  will be  cleared,  and  it  will  take  longer  than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other
vehicles are driven close by, it may take time for the system to recog-
nize  the  tire  pressure  warning  valve  and  transmitters  of  your  vehicle
over those of other vehicles.
• If a wheel with a tire pressure warning valve and transmitter installed
is  inside  or  near  the  vehicle,  registration  of  the  ID  codes  for the
installed wheels may not be possible.
If  ID  registration  is  not  complete  after  driving  for  approximately  1  hour,
park the vehicle in a safe place for approximately 20 minutes and then
perform the ID code registration procedure again.
●In the following situations, ID code registration will not be started or was
not  completed  properly  and  the  system  will  not operate  properly.  Per-
form the ID code registration procedure again.
• If,  when  attempting  to  start  ID  code  registration,  the  tire  pressure
warning light does not blink slowly 3 times.
• If,  when  the  vehicle  has  been  driven  for  about  20  minutes  after  per-
forming ID code registration, the tire pressure warning light blinks for
approximately 1 minute and then illuminates.
●If  ID  code  registration  cannot  be  completed  after  performing  the  above
procedure, contact your Toyota dealer.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous  handling  characteristics,  which  may  lead  to  an  accident
resulting in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do  not  mix  differently  constructed  tires  (radial,  bias-belted  or  bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously. 
■When initializing the tire pressure warning system
Do  not  initialize  the  tire  pressure  warning  system  without  first  adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pres-
sure warning light may not come on even if the tire inflation pressure is
low,  or  it  may  come  on  when  the  tire  inflation  pressure  is  actually  nor-
mal.

Maintenance and care
NOTICE
■Repairing  or  replacing  tires,  wheels,  tire  pressure  warning  valve
and transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitters, contact your Toyota dealer as the tire pressure
warning  valve  and  transmitters  may  be  damaged  if  not  handled  cor-
rectly.
●Make  sure  to  install  the  tire  valve  caps.  If  the  tire  valve  caps  are  not
installed, water may enter the valves of the tire pressure warning valve
and transmitters and the valves may become stuck.
●When  replacing  tire  valve  caps,  do  not  use  tire  valve  caps  other  than
those specified. The cap may become stuck.
■To  avoid  damage  to  the  tire  pressure  warning  valve  and  transmit-
ters
When  a  tire  is  repaired  with  liquid  sealants,  the  tire  pressure  warning
valve  and  transmitter  may  not  operate  properly.  If  a  liquid  sealant  is
used, contact your Toyota dealer or other qualified service shop as soon
as  possible.  Make  sure  to  replace  the  tire  pressure  warning  valve  and
transmitter when replacing the tire. (P.   3 9 6 )
■Driving on rough roads
Take  particular  care  when  driving  on  roads  with  loose  surfaces or  pot-
holes.
These  conditions  may  cause  losses in  tire  inflation  pressure,  reducing
the  cushioning  ability  of  the  tires.  In  addition,  driving  on  rough  roads
may  cause  damage  to  the  tires  themselves,  as  well  as  the  vehicle’s
wheels and body.
■Low profile tires (vehicles with 18 or 19-inch wheels)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention
to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire and wheel damage.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to deflate.
After  completing  the  tire  inflation  pressure  measurement  and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating, have it checked by your Toyota dealer.

■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If  your  vehicle  has  been  parked  for  at  least  3  hours  or  has  not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
●It  is  normal  for  the  tire  inflation  pressure  to  be  higher  after  driving  as
heat  is  generated  in  the  tire.  Do  not  reduce  tire  inflation  pressure  after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated. 
If the tires are not properly inflated,  the  following  conditions  may  occur
which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire damage
●Greater  possibility  of  tire  damage  while  driving  (due  to  road  hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.
