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 vehi-
cle 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 pres-
sure.
