If the vehicle is submerged or water on the road is rising
This vehicle is not designed to be able to drive on roads that are deeply flooded
with water. Do not drive on roads where the roads may be submerged or the water
may be rising. It is dangerous to remain in the vehicle, if it anticipated that the
vehicle will be flooded or set a drift.
Remain calm and follow the following.
●
If the door can be opened, open the door and exit the vehicle.
●
If the door cannot be opened, open the window using the power window switch
and ensure an escape route.
●
If the window can be opened, exit the vehicle through the window.
●
If the door and window cannot be opened due to the rising water, remain calm,
wait until the water level inside the vehicle rises to the point that the water
pressure inside of the vehicle equals the water pressure outside of the vehicle
and then open the door after waiting for the rising water to enter the vehicle, and
exit the vehicle.
9-1. What to do if a problem occurs while driving
606
When the outside water level exceeds half the height of the door, the door cannot be
opened from the inside due to water pressure.
INFORMATION
■

get damaged, the power windows will not operate, the engine and motor stop, and the
vehicle may not be able to get moving.

WARNING
■
Caution while driving
Do not drive on roads where the roads may be submerged or the water may be rising.
Otherwise the vehicle may be damaged and cannot move, as well as become flooded
and set a drift, which may lead to death.
Operation of emergency shut off system
When a certain level of impact is detected by an impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not be able to be restarted. To restart the hybrid system,
contact your Lexus dealer.
