CAUTION
■Hybrid battery (traction battery)
Never resell, hand over or modify the hybrid battery (traction battery). To pre-
vent  accidents,  hybrid  batteries  (traction  batteries)  that  have  been  removed
from  a  disposed  vehicle  are  collected  through  Toyota  dealers.  Do  not  dis-
pose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in
death or serious injury:
•The hybrid battery (traction battery) may be illegally disposed of or
dumped,  and  someone  may  touch  a  high  voltage  part,  resulting  in  an
electric shock.
•The hybrid battery (traction battery) is intended to be used exclusively
with  your  hybrid  vehicle.  If  the  hybrid  battery  (traction  battery)  is  used
outside of your vehicle or modified in any way, accidents such as electric
shock,  heat  generation,  smoke  generation,  an  explosion  and  electrolyte
leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident is
extremely high because the person receiving the vehicle may not be  aware
of these dangers.
■Disposal of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery (traction battery) hav-
ing been removed, there is a danger of serious electric shock if high voltage
parts, cables and their connectors are touched. In the event that your vehicle
must  be  disposed  of,  the  hybrid  battery  (traction  battery)  must  be  disposed
of  by  your  Toyota  dealer  or  a  qualified  service  shop.  If  the  hybrid  battery
(traction battery) is not disposed of properly, it may cause electric shock that
can result in death or serious injury.

■Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic  shielding,  and  therefore  emit  approximately  the  same  amount
of  electromagnetic  waves  as  conventional  gasoline  powered  vehicles  or
home electronic appliances.
●Yo u r   v e h i c l e   m a y   c a u s e   s o u n d   i n t e r f e r e n c e   i n   s o m e   t h i r d   p a r t y - p r o d u c e d

■Hybrid battery (traction battery) (lithium-ion battery)
The hybrid battery (traction battery) has a limited service life.
The  hybrid  battery  (traction  battery)  capacity  (the  ability  to  hold  a  charge)
reduces with time and use in the same way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how
the vehicle is driven and how the hybrid battery (traction battery) is charged.
This is a natural characteristic of lithium-ion batteries, and is not a malfunc-
tion.  Also,  even  though  the  distance  that  can  be  driven  in  EV  mode
decreases when the hybrid battery (traction battery) capacity reduces, vehi-
cle performance does not significantly become worse.
In  order  to  reduce  the  possibility  of  the  capacity  reducing,  follow  the  direc-
tions  listed  on  P.  98,  “Capacity  reduction  of  the  hybrid  battery  (traction  bat-
tery)”.

CAUTION
■High voltage precautions
The  vehicle  has  high  voltage  DC  and  AC  systems  as  well  as  a  12-volt  sys-
tem. DC and AC high voltage is very dangerous and can cause severe burns
and electric shock that may result in death or serious injury.
●Never  touch,  disassemble,  remove  or  replace  the  high  voltage  parts,
cables or their connectors.
●The  hybrid system  will  become hot  after  starting  as  the  system  uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the caution labels attached to the vehicle.
●Never  try  to  open  the  service  plug
access  hole  located  in  the  luggage
compartment.  The  service  plug  is  used
only when the vehicle is serviced and is
subject to high voltage.

PRIUS PHV_OM_OM47A11U_(U)
Yo u r   v e h i c l e   i s   e q u i p p e d   w i t h  ADVANCED AIRBAGS designed based
on  the  US  motor  vehicle  safety standards  (FMVSS208).  The  airbag
sensor  assembly  (ECU)  controls  airbag  deployment  based  on  infor-
mation  obtained  from  the  sensors etc.  shown  in  the  system  compo-
nents  diagram  above.  This  information  includes  crash  severity  and
occupant  information.  As  the  airbags  deploy,  a  chemical  reaction  in
the inflators quickly fills the airbags with nontoxic gas to help restrain
the motion of the occupants.
■If the SRS airbags deploy (inflate)
●Bruising  and  slight  abrasions  may  result  from  contact  with  a  deploying
(inflating) SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, parts of the front and rear pillars, and roof side
rails, may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event
of  a  severe  rear-end  collision,  the  system  is  designed  to  send  an  emer-
gency call to the response center, notifying them of the vehicle’s location
(without  needing  to  push  the  “SOS”  button)  and  an  agent  will  attempt  to
speak with the occupants to ascertain the level of emergency and assis-
tance  required.  If  the  occupants  are  unable  to  communicate,  the  agent
automatically  treats  the  call  as  an  emergency  and  helps  to  dispatch  the
necessary emergency services. ( oP.   4 2 1 )

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions. 
■Pre-winter preparations
●Use  fluids  that  are appropriate  to the  prevailing  outside  tem-
peratures. 
•Engine oil
•Engine/power control unit coolant
•Washer fluid
●Have a service technician inspect  the  condition of  the 12-volt
battery.
●Have  the  vehicle  fitted  with  four  snow  tires  or  purchase  a  set
of tire chains for the front tires. 
Ensure  that  all  tires  are  the  same  size  and  brand,  and  that  chains
match the size of the tires.
