WARNING
Observe the following precautions. 
Failure  to  do  so  may  cause  the  driver’s  floor  mat  to  slip,  possibly  interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. This could lead to an accident, resulting in
death or serious injury.
■When installing the driver’s floor mat 
●Do  not  use  floor  mats  designed  for  other  models  or  different  model  year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always  install  the floor  mat  securely  using  the retaining  hooks (clips)  pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
●Check  that  the  floor  mat  is  securely
fixed  in  the  correct  place  with  all  the
provided  retaining  hooks  (clips).  Be
especially  careful  to  perform  this  check
after cleaning the floor.
● With  the  engine  stopped  and  the  shift
lever  in  P,  fully  depress  each  pedal  to
the  floor  to  make  sure  it  does  not  inter-
fere with the floor mat.

WARNING
■When installing a child restraint system
●When  installing  a  child  restraint  system  on  the  third  center  seat,  adjust
both  seatbacks  at  the  same  angle.  Otherwise,  the  child  restraint  system
cannot be securely restrained and this may cause death or serious injuries
in the event of sudden braking, sudden swerving or an accident.
● When using the LATCH anchors for a child restraint system, move the seat
as far back as possible (second seat only), with the seatback close to the
child restraint system.
● When  a  booster  seat  is  installed,  always  ensure  that  the  shoulder  belt  is
positioned  across  the  center  of  the  child’s  shoulder.  The  belt  should  be
kept  away  from  the  child’s  neck,  but  not  so  that  it  could  fall  off  the  child’s
shoulder. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
● Ensure that the belt and plate are securely locked and the seat belt is not
twisted.
● Shake the child restraint system left and right, and forward and backward
to ensure that it has been securely installed.
● After securing a child restraint system, never adjust the seat.
● Follow  all  installation  instructions  provided  by  the  child  restraint  system
manufacturer.
● When securing some types of child restraint systems in second (8-passen-
ger  models)  or  third  row  seats,  it  may  not  be  possible  to  properly  use  the
seat belts in positions next to the child restraint without interfering with it or
affecting  seat  belt  effectiveness.  Be  sure  your  seat  belt  fits  snugly  across
your shoulder and low on your hips. if it dose not, or if it interferes with the
child  restraint,  move  to  a  different  position.  Failure  to  do  so  may  result  in
death or serious injury.
