WARNING
■Used engine oil
● Used  engine  oil  contains  potentially  harmful  contaminants  which  may
cause  skin  disorders  such  as  inflammation  and  skin  cancer,  so  c are
should be taken to avoid prolonged and repeated contact. To remove used
engine oil from your skin, wash thoroughly with soap and water.
● Dispose  of  used  oil  and  filters  only  in  a  safe  and  acceptable  manner.  Do
not dispose of used oil and filters in household trash, in sewe rs or onto the
ground.  Call  your  Toyota  dealer,  service  station  or  auto  parts  store  for
information concerning recycling or disposal.
● Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil
● Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, or the engine could be damaged.
● Check the oil level on the dipstick every time you refill the v ehicle.
● Be sure the engine oil filler cap is properly tightened.

WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner's Manual, as this may  result in a loss of handling control.
●Never  use  an  inner  tube  in  a  leaking  wheel  which  is  designed  fo r  a
tubeless tire. Doing so may resu lt in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts. 
Oil and grease may cause the wheel nuts to be excessively tight ened,
leading to bolt or disc wheel damage. In addition, the oil or g rease can
cause the wheel nuts to loosen and the wheel may fall off, caus ing an
accident  and  resulting  in  death  or  serious  injury.  Remove  any  oil  or
grease from the wheel  bolts or wheel nuts.
NOTICE
■Replacing tire pressure warn ing valves and transmitters
●Because  tire  repair  or  replacement  may  affect  the  tire  pressure   warn-
ing  valves  and  transmitters,  make  sure  to  have  tires  serviced  b y  your
Toyota dealer or other  qualified service shop. In addition, make sure to
purchase  your  tire  pressure  warning  valves  and  transmitters  at  your
Toyota dealer.
●Ensure that only genuine Toyota  wheels are used on your vehicle. 
Tire  pressure  warning  valves  and  transmitters  may  not  work  prop erly
with non-genuine wheels. 
●Be  sure  to  install  the  wheel  nuts  with
the  tapered  ends  facing  inward.
Installing  the  nuts  with  the  tapered
ends  facing  outward  can  cause  the
wheel  to  break  and  eventually  cause
the  wheel  to  come  off  while  driving,
which  could  lead  to  an  accident
resulting in death o r serious injury.Tapered

■LED light bulbs
The  headlights/daytime  running  lights,  front  fog  lights  (if  equipped),  side
marker  lights,  side  turn  signal  lights,  stop/tail  lights  and  hi gh  mounted  stop-
light consist of a number of LEDs. If any of the LEDs burn out, take your vehi-
cle to your Toyota dealer to have the light replaced.
■ Condensation build-up on the inside of the lens
Temporary condensation build-up on the inside of the headlight  lens does not
indicate a malfunction. Contact your Toyota dealer for more information in the
following situations:
● Large drops of water have built up on the inside of the lens.
● Water has built up inside the headlight.
WARNING
■Replacing light bulbs
● Turn  off  the  lights.  Do  not  attempt  to  replace  the  bulb  immedia tely  after
turning off the lights. 
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clea n dry cloth
to avoid getting moisture and oils on the bulb. 
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Fa ilure to do so
may  result  in  heat  damage,  fire,  or  water  entering  the  headligh t  unit. This
may damage the headlights or cause condensation to build up on  the lens.
■ To prevent damage or fire 
Make sure bulbs are fully seated and locked.

*: The engine oil  capacity is a reference  quantity to be  used when changing
the  engine  oil.  Warm  up  the  engine  and  turn  off  the  hybrid  system,  wait
more than 5 minutes, and check the oil level on the dipstick.

Engine oil selection
“Toyota  Genuine  Motor  Oil”  is  used  in  your  Toyota  vehicle.  Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat isfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE  0W-20  is  the  best  choice
for  good  fuel  economy  and
good starting in cold weather.
If  SAE  0W-20  is  not  available,
SAE  5W-20  oil  may  be  used.
However,  it  must  be  replaced
with  SAE  0W-20  at  the  next  oil
change.

Oil viscosity (0W-20 is explained here as an example):
• The  0W  in  0W-20  indicates  the  characteristic  of  the  oil  which allows cold startability. Oils wi th a lower value before the W allow
for easier starting of the engine in cold weather.
• The  20  in  0W-20  indicates  the  vi scosity  characteristic  of  the oil
when the oil is at high temperature. An oil with a higher visco sity
(one  with  a  higher  value)  may  be  better  suited  if  the  vehicle  i s
operated at high speeds, or un der extreme load conditions.
How to read oil container label:
The  International  Lubricant
Specification  Advisory  Commit-
tee  (ILSAC)  Certification  Mark
is added to  some oil  containers
to  help  you  select  the  oil  you
should use.
