WARNING
■When driving on slippery road surfaces 
Do not accelerate or shift the shift lever suddenly.  
Sudden  changes  in  engine  braking  may  cause  the  vehicle  to  spin  or  skid, 
resulting in an accident. 
■ To prevent an accident when releasing the shift lock 
Before pressing the shift lock override button, make sure to se t the parking 
brake and depress the brake pedal.  
If the accelerator pedal is accidentally depressed instead of t he brake pedal 
when  the  shift  lock  override  button  is  pressed  and  the  shift  le ver  is  shifted 
out  of  P,  the  vehicle  may  suddenly  start,  possibly  leading  to  a n  accident 
resulting in death or serious injury.
NOTICE
■ Hybrid battery (traction battery) charge 
If  the  shift  lever  is  in  N,  the  hybrid  battery  (traction  batter y)  will  not  be 
charged. To  help  prevent  the  battery  from  discharging,  avoid  le aving the  N 
position selected for an extended period of time.

■Before recharging 
When  recharging,  the  12-volt  battery  produces  hydrogen  gas  whic h  is  flam- 
mable  and  explosive.  Therefore,  observe  the  following  precautio ns  before 
recharging: 
● If recharging with the 12-volt battery installed on the vehicle, be sure to dis- 
connect the ground cable. 
● Make sure the power switch on the charger is off when connecting and dis- 
connecting the charger cables to the 12-volt battery. 
■ After recharging/reconnecting the 12-volt battery 
● The hybrid system may not start. Follow the procedure below to initialize the 
system. 
Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
● Vehicles  with  entry  function:  Unlocking  the  doors  using  the  smart  entry  & 
start system may not be possible immediately after reconnecting  the 12-volt 
battery.  If  this  happens,  use  the  wireless  remote  control  or  th e  mechanical 
key to lock/unlock the doors. 
● Start  the  hybrid  system  with  the  power  switch  in ACCESSORY  mode.  The 
hybrid  system  may not  start  with  the  power  switch  turned  off. H owever,  the 
hybrid system will operate normally from the second attempt. 
● The  power  switch  mode  is  recorded  by  the  vehicle.  If  the  12-volt  battery  is 
reconnected,  the  vehicle  will  return  the  power  switch  mode  to  t he  status  it 
was  in  before  the  12-volt  battery  was  disconnected.  Make  sure  t o  turn  off 
the  power  switch  before  disconnect  the  12-volt  battery.  Take  ex tra  care 
when  connecting  the  12-volt  battery  if  the  power  switch  mode  pr ior  to  dis- 
charge is unknown. 
If the system will not start even after multiple attempts at al l methods above, 
contact  any  authorized  Toyota  retailer  or  Toyota  authorized  rep airer,  or  any 
reliable repairer.

WARNING
■When there is insufficient 12-volt battery fluid 
Do not use if there is insufficient fluid in the 12-volt batter y. There is a possi- 
ble danger that the 12-volt battery may explode. 
■ When disconnecting the 12-volt battery 
Do  not  disconnect  the  negative  (-)  terminal  on  the  body  side.  T he  discon- 
nected negative (-) terminal may touch the positive (+) termina l, which may 
cause a short and result in death or serious injury.
NOTICE
■ When recharging the 12-volt battery 
Never  recharge  the  12-volt  battery  while  the  hybrid  system  is  o perating. 
Also, be sure all accessories are turned off. 
■ When adding distilled water 
Avoid  overfilling.  Water  spilled  during  battery  recharging  may  cause  corro- 
sion.

Maintenance and care
■Cleaning the air intake vent 
● Dust in the air intake vent may interfere with the cooling of the hybrid battery 
(traction  battery).  If  charging/discharging  of  the  hybrid  batte ry  (traction  bat- 
tery) becomes limited, the distance that the vehicle can be dri ven using the 
electric  motor  (traction  motor)  may  be  reduced  and  the  fuel  eco nomy  may 
be reduced. Inspect and clean the air intake vent periodically. 
● Improper  handling  of  the  air  intake  vent  cover  and  filter  may  result in dam- 
age to them. If you have any concerns about cleaning the filter , contact any 
authorized  Toyota  retailer  or  Toyota  authorized  repairer,  or  an y  reliable 
repairer. 
■ If  “Maintenance  required  for  Traction  battery  cooling  parts  See owner’s 
manual.” is shown on the multi-information display 
● If  this  message  is  shown  on  the  multi-information  display,  remove the air 
intake vent cover and clean the filter. ( P. 640) 
● After cleaning the air intake vent, start the hybrid system and check that the 
warning message is no longer displayed.  
After  the  hybrid  system  is  started,  it  may  be  necessary  to  driv e  the  vehicle 
up to approximately 20 minutes before the warning message disap pears. If 
the  warning  message  does  not  disappear  after  driving  for  approp riately  20 
minutes,  have  the  vehicle  inspected  by  any  authorized  Toyota  re tailer  or 
Toyota authorized repairer, or any reliable repairer.
WARNING
■ When cleaning the air intake vent 
● Before cleaning the air intake vent, make sure to turn the power switch off 
to stop the hybrid system. 
● Do  not  use  water  or  other  liquids  to  clean  the  air  intake  vent.  If  water  is 
applied to the hybrid battery (traction battery) or other compo nents, a mal- 
function or fire may occur. 
■ When removing the air intake vent cover 
Do not touch the service plug located near the air intake vent.  (P. 126)
