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 acc ident, resulting in
death or serious injury.
■ When installing the dr iver's floor mat 
● Do  not  use  floor  mats  designed  for  other  models  or  different  mo del  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 hybrid system stopped and the
shift lever in P, fully depress each pedal
to  the  floor  to  make  sure  it  does  not
interfere with the floor mat.

PRIUS c_U
WARNING
■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do  not  allow  children  to  play  with  the  seat  belt.  If  the  seat  b elt  becomes
twisted around a child’s neck, it may lead to choking or other serious inju-
ries that could result in death.
If  this  occurs  and  the  buckle  cannot  be  unfastened,  scissors  sh ould  be
used to cut the belt.
● 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.
● When  a  booster  seat  is  installed,  always  ensure  that  the  should er  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.
● Follow  all  installation  instructions  provided  by  the  child  rest raint  system
manufacturer.
● When securing some types of child restraint systems in rear 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  ef fectiveness.  Be
sure your seat belt fits snugly across your shoulder and low on  your hips. If
it  does  not,  or  if  it  interferes  with  the  child  restraint,  move   to  a  different
position. Failure to do so may result in death or serious injur y.
■ When installing a booster seat
To  prevent  the  belt  from  going  into ALR  lock  mode,  do  not  fully   extend  the
shoulder  belt. ALR  mode  causes  the  belt  to  tighten  only.  This  c ould  cause
injury or discomfort to the child. ( P. 34)
■ Do not use a seat belt extender
If  a  seat  belt  extender  is  used  when  installing  a  child  restraint  system,  the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the  event of sud-
den braking, sudden swerving or an accident.

■ Eco score
●As the accelerator pedal is not depressed, the driven distance  using cruise
control (if equipped) is not included in the eco score.

ronmental factors, in some cases it may not be linked to fuel c onsumption. 
■ Eco savings
●Fuel cost and savings should be used as a guide only.
● Depending on refueling methods, driving conditions and environm ental fac-
tors, the actual and displayed fuel costs may differ.
● In  some  cases,  fuel  cost  and  savings  may  not  be  linked  to  the  eco  score
evaluation.
