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.
■
Water level exceeds the floor
When the water level exceeds the floor and time has passed, the electrical 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
When using a flatbed truck to transport the vehicle, use tire strapping belts. Refer
to the owner’s manual of the flatbed truck for the tire strapping method.
In order to suppress vehicle movement during transportation, set the parking
brake and turn the engine switch off.
If a tow truck is not available in an emergency, your vehicle may be temporarily
towed using cables or chains secured to the emergency towing hooks. This
should only be attempted on hard surfaced roads for at most 50 miles (80 km)
at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes. The vehicle’s
wheels, drive train, axles, steering and brakes must be in good condition.

When towing the vehicle
■
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 damage.
●
For models with the rear height control air suspension: Make sure to disable all func-
tions of the vehicle height control of the rear height control air suspension. Other-
wise, the vehicle height may change and part of your body may be caught under the
vehicle, possibly causing injury. (
●
Do not turn the engine switch off.
There is a possibility that the steering wheel is locked and cannot be operated.
Be sure to transport the vehicle with all four
wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground, the
drivetrain or related parts may be damaged,
the vehicle may fly off the truck.
