 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 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.
■Water level exceeds the floor
When the water level exceeds the
floor and time has passed, the elec-
trical equipment will get damaged,
the power windows will not operate,
the engine stop, and the vehicle
may not be able to get moving.

When trouble arises
7-2.Steps to take in an emergency
If your vehicle needs
to be towed
If towing is necessary, we
recommend having your
vehicle towed by your Toy-
ota dealer or commercial
towing service, using a
wheel-lift type truck or flat-
bed truck.
Use a safety chain system
for all towing, and abide by
all state/provincial and local
laws.
WARNING
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
■When towing the vehicle
Be sure to transport the vehicle
with the front wh eels raised or
with all four wheels raised off the
ground. If the vehicle is towed
with the front wh eels contacting
the ground, the drivetrain and
related parts may be damaged.
■While towing
●When towing using cables or
chains, avoid sudden starts, etc.
which place excessive stress on
the towing eyelets, cables or
chains. The towing eyelets,
cables or chains may become
damaged, broken debris may hit
people, and cause serious dam-
age.
●Do not turn the engine switch
off.
There is a possibility that the
steering wheel is locked and
cannot be operated.
■Installing towing eyelets to
the vehicle
Make sure that towing eyelets are
installed securely.
If not securely installed, towing
eyelets may come loose during
towing.
NOTICE
■To prevent damage to the
vehicle when t owing using a
wheel-lift type truck
●Vehicles without a smart key
system: Do not tow the vehicle
from the rear when the engine
switch is off or the key is
removed. The steering lock
mechanism is not strong
enough to hold the front wheels
straight.
●Vehicles with a smart key sys-
tem: Do not tow the vehicle from
the rear when the engine switch
is off.
●When raising the vehicle,
ensure adequate ground clear-
ance for towing at the opposite
end of the raised vehicle. With-
out adequate clearance, the
vehicle could be damaged while
being towed.
