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 P position control system is damaged by flooding, it may not be possi-
ble to shift the shift position to P, or from P to other positions. When the shift
position 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.
