WARNING
■When using the rear view monitor system 
The  rear  view  monitor  system  is  a  supplemental  device  intended  to  assist
the driver when backing up. When backing up, be sure to visually check all
around the vehicle both directly and using the mirrors before p roceeding. If
you do not, you may hit another vehicle, and could possibly cau se an acci-
dent.
Pay attention to the following precautions when using the rear  view monitor
system.
● Never depend on the rear view monitor system entirely when back ing up.
The image and the position of the guide lines displayed on the  screen may
differ from the actual state. 
Use caution, just as you would when backing up any vehicle.
● Be  sure  to  back  up  slowly,  depressing  the  brake  pedal  to  contro l  vehicle
speed.
● The instructions given are only guidelines.
When and how much to turn the steering wheel will vary accordin g to traf-
fic  conditions,  road  surface  conditions,  vehicle  condition,  etc .  when  park-
ing.  It  is  necessary  to  be  fully  aware  of  this  before  using  the   rear  view
monitor system. 
● When parking, be sure to check that the parking space will acco mmodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slop es.
● In  low  temperatures,  the  screen  may  darken  or  the  image  may  bec ome
faint.  The  image  could  distort  when  the  vehicle  is  moving,  or  y ou  may
become unable to see the image on the screen. Be sure to visual ly check
all  around  the  vehicle  both  directly  and  using  the  mirrors  befo re  proceed-
ing.
● If the tire sizes are changed, the position of the fixed guide  lines displayed
on the screen may change.
● The  camera  uses  a  special  lens.  The  distances  between  objects  a nd
pedestrians  that  appear  in  the  image  displayed  on  the  screen  will  differ
from the actual distances. ( P. 258)

If  the  tire  pressure  warning  light  frequently  comes  on  after  bl inking  for  1
minute  when  the  power  switch  is  turned  to  the  “ON”  position  (ve hicles
without  a  smart  key  system)  or  the  power  switch  is  turned  to  ON   mode
(vehicles  with  a  smart  key  system) ,  have  it  checked  by  your  Toyota
dealer.
■ Customization that can be configured at Toyota dealer
The  vehicle  speed  linked  seat  belt  reminder  buzzer  can  be  disab led.  (Cus-
tomizable features:  P. 560) However, Toyota recommends that the seat belt
reminder  buzzer  be  operational  to  alert  the  driver  and  front  pa ssenger  when
seat belts are not fastened.
■ Warning buzzer
In  some  cases,  the  buzzer  may  not  be  heard  because  of  noisy  pla ce  or  an
audio sound.
WARNING
■ When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
When  steering  wheel  operations  are  heavier  than  usual,  grip  the  steering
wheel firmly and operate it 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  t he  tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inf lation pres-
sure adjustment, it is probable that you have a flat tire. Chec k the tires.
If  a  tire  is  flat,  change  it  with  the  spare  tire  and  have  the  f lat  tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate,
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.

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  p ressure
label  (tire  and  load  information  label).  (If  your  vehicle  has  t ires  of  a  dif-
ferent size than the size indica ted on the vehicle placard or tire inflation
pressure  label  [tire  and  load  information  label],  you  should  de termine
the proper tire inflation p ressure 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.  Acco rdingly,
when  the  low  tire  pressure  telltale  (tire  pressure  warning  ligh t)  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  lif e, and may
affect the vehicle’s handl ing and stopping ability.
Please note that the TPMS (tire pressure warning system) is not  a sub-
stitute for proper tire maintena nce, 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  indicato r  to  indicate  when  the  system  is  not
operating  properly. The TPMS  (tire  pressure  warning  system)  mal func-
tion indicator is combined with  the low tire pressure telltale (tire pressure
warning  light).  When  the  system  detects  a  malfunction,  the  tell tale  will
flash for approximately one mi nute and then remain continuously  illumi-
nated.  This  sequence  will  continue  upon  subsequent  vehicle  star t-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  tir e  pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for  a vari-
ety of reasons, including the installation of replacement or al ternate tires
or  wheels  on  the  vehicle  that  prevent  the TPMS  (tire  pressure  w arning
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 sys tem) to
continue to function properly.
