NOTICE
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. D oing 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 i s flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, 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, transp ort the vehi-
cle with both front wheels or all four wheels lifted. ( P. 655)
