When trouble arises
■When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: P. 471
If none of the tires are punctured:
Turn the power switch off then turn it to ON mode. Check if the tire pres-
sure warning light comes on or blinks.
If the tire pressure warning light comes on
After  the  temperature  of  the  tires  has  lowered  sufficiently,  check  the
inflation pressure of each tire and adjust them to the specified level.
If  the  warning  light  does  not  turn  off  even  after  several  minutes  have
elapsed, check that the inflation pressure of each tire is at the specified
level and perform initialization. (P.   4 1 7 )
If the warning light does not turn off several minutes after the initialization
has  been  performed,  have  the  vehicle  inspected  by  your  Toyota  dealer
immediately.
If the tire pressure warning light blinks for 1 minute then stays on
There  may  be  a  malfunction  in  the  tire  pressure  warning  system. Have
the vehicle inspected by your Toyota dealer immediately.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as  natural  air  leaks  and  tire  inflation  pressure  changes  caused by tem-
perature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning valve
and  transmitter.  If  a  tire  goes  flat,  the  tire  pressure  warning  light  will  not
turn  off  even  though  the  flat  tire  has  been  replaced  with  the  spare  tire.
Replace  the  spare  tire  with  the  repaired  tire  and  adjust  the  tire  inflation
pressure. The tire pressure warning light will go off after a few minutes.
■Conditions  that  the  tire  pressure  warning  system  may  not  function
properly
P.   4 2 2
■Warning buzzer
In  some  cases,  the  buzzer  may  not  be  heard  because  of  noisy  place  or
an audio sound.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop  your  vehicle  in  a  safe  place  immediately  and  contact  your To y o t a
dealer. The vehicle will become extremely unstable during braking, and the
ABS  system  may  fail,  which  could  cause  an  accident  resulting  in  death  or
serious injury.
■When the electric power steering system warning light comes on
When  the  light  comes  on  yellow,  the  assist  to  the  power  steering  is
restricted. When the light comes on red, the assist to the power steering is
lost  and  handling  operations  of  the  steering  wheel  become  extremely
heavy.
If  the  steering  wheel  becomes  heavier  than  usual  when  operating,  hold
firmly and operate using more force than usual.
■
If the tire pressure warning light comes on
Be  sure  to  observe  the  following  precautions.  Failure  to  do  so could
cause a loss of vehicle control and result in death or serious injury.
●Stop  your  vehicle  in  a  safe  place  as  soon  as  possible. Adjust  the  tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If  a  tire  is  flat,  change  it  with  the  spare  tire  and  have  the  flat  tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

When trouble arises
WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when  cold  and  inflated  to  the  inflation  pressure  recommended  by the
vehicle  manufacturer  on  the  vehicle  placard  or  tire  inflation  pressure
label  (tire  and  load  information  label).  (If  your  vehicle  has  tires  of  a  dif-
ferent size than the size indicated on the vehicle placard or tire inflation
pressure  label  [tire  and  load  information  label],  you  should  determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure  monitoring  system  (TPMS-tire  pressure  warning  system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one  or  more  of  your  tires  is  significantly  under-inflated.  Accordingly,
when  the  low  tire  pressure  telltale  (tire  pressure  warning  light)  illumi-
nates,  you  should  stop  and  check  your  tires  as  soon  as  possible,  and
inflate  them  to  the  proper  pressure.  Driving  on  a  significantly  under-
inflated  tire  causes  the  tire  to  overheat  and  can  lead  to  tire failure.
Under-inflation  also  reduces  fuel  efficiency  and  tire  tread  life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s responsibility to
maintain  correct  tire  pressure,  even  if  under-inflation  has  not  reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing  system)  malfunction  indicator  to  indicate  when  the  system  is  not
operating  properly. The TPMS  (tire  pressure  warning  system)  malfunc-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning  light).  When  the  system  detects  a  malfunction,  the  telltale  will
flash for approximately one minute and then remain continuously illumi-
nated.  This  sequence  will  continue  upon  subsequent  vehicle  start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated,  the  system  may  not  be  able  to  detect  or  signal  low  tire  pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or  wheels  on  the  vehicle  that  prevent  the TPMS  (tire  pressure  warning
system)  from  functioning  properly. Always  check  the  TPMS  (tire pres-
sure  warning  system)  malfunction telltale  after  replacing  one  or  more
tires  or  wheels  on  your  vehicle  to  ensure  that  the  replacement or  alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
