◆Installing tire pressure warning valve and transmitters
When replacing the tires or wheels, the tire pressure warning v alve
and  transmitters  must  be  install ed  to  the  wheels  which  will  be
installed to the vehicle.
When  new  tire  pressure  warning  valve  and  transmitters  are
installed,  new  ID  codes  must  be  registered  in  the  tire  pressure
warning  computer  and  the  tire  pressure  warning  system  must  be
initialized. ( P. 477)
◆Initializing the tire pressure warning system
■The tire pressure warning system  must be initialized in the fol-
lowing circumstances:
● When the tire inflation pressure is changed such as when chang-
ing traveling speed  or load weight.
● When the tire inflation pressure is changed such as when the ti re
size is changed.
● When rotating the tires.
● Vehicles  with  a  tire  inflation  pr essure  display  function: After per-
forming the transmitter ID code registration procedure. ( P.   4 7 7 )
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  a  safe place  and stop  the engine for  20 min -
utes or more.
The  initialization  procedure  cannot  be  started  while  the  vehicle  is
moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 584)
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.
Start the engine. ( P. 209, 211)
Select    (4.2-inch  display)  or    (7-inch  display)  on  the  multi-
information display using the meter control switches on the ste er-
ing wheel. ( P. 103, 117).

Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You  have  tire  damage  such  as  cuts,  splits,  cracks  deep  enough  t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due  to the size
or location of a cut or other damage
If you are not sure, consult  with your Toyota dealer.
■Replacing tires and wheels
If the ID codes of the tire pressure warning valve and transmit ters are not
registered, the tire pressure warning system will not work properly. In this
case, after driving for about 20 minutes, the tire pressure warning light will
blink for approximately 1 minute and then illuminate to indicat e a system
malfunction.
■Tire life
Any tire over 6 years old must  be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks
The  tire  pressure  warning  system  does  not  replace  routine  tire  inflation
pressure  checks.  Make  sure  to  chec k  tire  inflation  pressure  as part  of
your routine of daily vehicle checks.
■Low profile tires (vehicles  with 18 or 19-inch wheels)
Generally,  low  profile  tires  will  wear  more  rapidly  and  tire  gr ip  perfor-
mance  will  be  reduced  on  snowy  and /or  icy  roads  when  compared  to
standard  tires.  Be  sure  to use snow  tires on snowy  and/or  icy  r oads and
drive carefully at a speed approp riate for road and weather conditions.
■Maximum load of tire
Check that the maximum load of t he replacement tire is greater than 1/2
of  the  Gross Axle  Weight  Ratings  (GAWR)  of  either  the  front  axl e  or  the
rear axle, whichever is greater.
For  the  GAWR,  see  the  Certification
Label. For the maximum load of the tire,
see  the  load  limit  at  maximum  cold  tire
inflation  pressure  mentioned  on  the
sidewall of the tire. ( P.   5 9 3 )

Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to hi
ghway
driving under dry conditions. Si nce summer tires do not have th e same
traction  performance  as  snow  tires,  summer  tires  are  inadequate  for
driving  on  snow-covered  or  icy  ro ads.  For  driving  on  snow-covered
roads or icy roads, the use of snow tires is recommended. When  install-
ing snow tires, be sure to replace all four tires.
●All season tires
All  season  tires  are  designed  to  provide  better  traction  in  sno w  and  to
be  adequate  for  driving  in  most  winter  conditions  as  well  as  fo r  use
year-round.  All  season  tires,  however,  do  not  have  adequate  tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season  tires  fall  short  in  acceleration  and  handling  performanc e  com-
pared with summer tires in highway driving.
●Snow tires
For  driving  on  snow-covered  roads  or  icy  roads,  we  recommend  us ing
snow  tires.  If  you  need  snow  tires,  select  tires  of  the  same  si ze,  con-
struction  and  load  capacity  as  t he  originally  installed  tires. Since  your
vehicle  has  radial  tires  as  original  equipment,  make  sure  your  snow
tires  also  have  radial  construct ion.  Do  not  install  studded  tires  without
first  checking  local  regulations  for  possible  restrictions.  Sno w  tires
should be install ed on all wheels. ( P. 377)
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■Situations  in  which  the  tire  pressure  warning  system  may  not  op er-
ate properly
●In  the  following  situations,  the  tire  pressure  warning  system  m ay  not
operate properly.
• If non-genuine Toyota wheels are used. 
• If  a  tire  has  been  replaced  with  a  tire  that  is  not  an  OE  (Ori ginal
Equipment) tire.
• If a tire has been replaced with a tire that is not of the spe cified size.
• If tire chains, e tc. are installed.
• If a window tint that affects r adio wave signals is installed.
• If  there  is  a  lot  of  snow  or  ice  on  the  vehicle,  particularly  around  the
wheels or wheel housings.
• If the tire inflation pressure  is much higher than the specifi ed level.
• If wheels not equipped with tire pressure warning valve and tr ansmit-
ter are used.
• If the ID codes of the tire pre ssure warning valve and transmi tters are
not registered in the tire  pressure warning computer.

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  facilit y  that  generates  strong
radio waves or electrical noise
• When  carrying  a  portable  radio,  cellular  phone,  cordless  phone  or
other wireless communication device
Vehicles  with  a  tire  inflation  pressure  display  function:  If  ti re  position
information is not correctly displayed due to the radio wave co nditions,
the display may be corrected by changing the location of the ve hicle 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  exampl e  when  a
tire has burst, the warning may not operate.
■Initialization procedure
●Make sure  to perform the  initialization procedure after adjusti ng the tire
inflation pressure.
Also,  make  sure  the  tires  are  cold  before  performing  the  initia lization
procedure or adjusting the  tire inflation pressure.
●If the engine switch is turned t o the “LOCK” position (vehicles  without a
smart  key  system)  or  off  (vehicles  with  a  smart  key  system)  dur ing  ini-
tialization,  it  is  not  necessary   to  restart  the  initialization procedure  from
the  beginning  as  it  will  begin  aut omatically  when  the  engine  switch  is
turned  back  to  the  “ON”  position  (vehicles  without  a  smart  key  system)
or IGNITION ON mode (vehicles with a smart key system).
●If  initialization  has  accidentally  been  started  when  it  is  not  necessary,
adjust the tire inflation pressu re to the specified level when  the tires are
cold and then perform the ini tialization procedure again.
●Vehicles with a tire inflation p ressure display function: While  the position
of each tire is being determined  and the inflation pressures are not being
displayed  on  the  multi-information  display,  if  the  inflation  pr essure  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  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.

Maintenance and care
■When registering ID codes (vehicles with a tire inflation pressure dis-
play function)
●Before  performing  ID  code  registration,  make  sure  that  no  wheel s  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 t he ID codes,
the initialized values will be invalid.
●As  the  tires  will  be  war m  when  registration  is  completed,  make  sure  to
allow the tires to cool befo re performing initialization.
■Canceling ID code registration ( vehicles with a tire inflation pressure
display function)
●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 r egistration start procedure aga in and turn
the engine switch of f before driving.
●If ID code registration has been canceled, the tire pressure wa rning light
will blink for approximately 1 mi nute when the engine switch is turned to
the  “ON”  position  (vehicles  witho ut a smart key system) or IGNITION
ON  mode  (vehicles  with  a  smart  ke y  system)  and  then  illuminate. The
tire  pressure  warning  system  will  be  operational  when  the  tire pressure
warning ligh t turns off.
●If  the  warning  light  does  not  turn  off  even  after  several  minut es  have
elapsed, ID code registration may not have been cancelled corre ctly. To
cancel  registration,  perform  the  ID  code  registration  start  procedure
again and then turn the engine switch off before driving.

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  accide nt
resulting in death o r serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other th an those recommended by Toyota.
●Do  not  mix  differently  constructed  tires  (radial,  bias-belted  o r  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 kn ow how they were used previously. 
■When initializing the tire pressure warning system
Do  not  initialize  the  tire  press ure  warning  system  without  firs t  adjusting
the tire inflation pressure to t he specified level. Otherwise,  the tire pres-
sure warning light may not come on even if the tire inflation p ressure is
low,  or  it  may  come  on  when  the  tire  inflation  pressure  is  actu ally  nor-
mal.

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  co r-
rectly.
●Make  sure  to  install  the  tire  val ve  caps.  If  the  tire  valve  caps  are  not
installed, water may enter the valves of the tire pressure warn ing valve
and transmitters and the valves may become stuck.
●When replacing tire valve caps, do not replace them with metal  caps or
any tire valve caps other than s pecified, as they may become st uck.
■To  avoid  damage  to  the  tire  pressure  warning  valve  and  transmit -
ters
When  a  tire  is  repaired  with  liqui d  sealants,  the  tire  pressure  warning
valve  and  transmitter  may  not  operate  properly.  If  a  liquid  sea lant  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. 475)
■Driving on rough roads
Take  particular  care  when  drivi ng  on  roads  with  loose  surfaces  or  pot-
holes.
These  conditions  may  cause  losses  in  tire  inflation  pressure,  reducing
the  cushioning  ability  of  the  t ires.  In  addition,  driving  on  ro ugh  roads
may  cause  damage  to  the  tires  themselves,  as  well  as  the  vehicl e’s
wheels and body.
■Low profile tires (vehicles w ith 18 or 19-inch wheels)
Low profile tires may cause gre ater 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 und er-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 drivi ng
Do not continue driving, or your t ires and/or wheels may be ruined.

Maintenance and care
■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 o nly 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  pre ssure  after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehi cle is
balanced.
WARNING
■Proper inflation is  critical to save tire performance
Keep your tires properly inflated. 
If  the  tires  are  not  properly  in flated,  the  following  conditions  may  occur
which could lead to an accident resulting in death or serious i njury:
●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  h azards,
expansion joints, sharp edges on the road, etc.)
NOTICE
■When inspecting and adjusti ng 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 pressu re.
