When driving
NOTICE
■When encountering flooded roads
Do  not  drive  on  a  road  that  has  flooded  after  heavy  rain  etc.  Doing  so  may
cause the following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In  the  event  that  you  drive  on  a  flooded  road  and  the  vehicle  is  flooded,  be
sure to have your Toyota dealer check the following:
●Brake function
●Changes  in  quantity  and  quality  of  engine  oil,  transmission  fluid  for  the
hybrid system, etc.
●Lubricant  condition  for  the  bearings  and  suspension  joints  (where  possi-
ble), and the function of all joints, bearings, etc.
If  the  shift  control  system  is  damaged  by flooding,  it  may not  be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion  cannot  be  changed  from  P  to  any  other  position,  the  front  wheels  will
lock,  and  you  will  be  unable  to  tow  the  vehicle  with  the  front  wheels  on  the
ground, as the front wheels may be locked. In this case, transport the vehicle
with both front wheels or all four wheels lifted.

CAUTION
■Replacing tires
Make sure that all tires are of the specified size and of the same brand, tread
pattern  and  total  load  capacity.  In  addition,  make  sure  that  the  tires  are
inflated to the recommended tire inflation pressure level.
The  ABS  and  VSC  systems  will  not  function  correctly  if  different  tires  are
installed on the vehicle.
Contact  your  Toyota  dealer  for  further  information  when  replacing  tires  or
wheels.
■Handling of tires and the suspension
Using  tires  with  any  kind  of  problem  or  modifying  the  suspension  will  affect
the driving assist systems, and may cause a system to malfunction.
