If the vehicle is submerged or water on the
road is rising
● If the door can be opened, open the door and exit the vehicle.
● If the door can not 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. When
the outside water level exceeds half the height of the door, the door
cannot be opened from the inside due to water pressure.
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 dan-
gerous to remain in the vehicle, if it anticipated that the vehicle
will be flooded or set a drift. Remain calm and follow the follow-
ing.
