WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■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 eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple, and cause serious damage.
● Do not turn the engine switch to the “LOCK” position (vehicles without a
smart key system) or the “POWER” switch off (vehicles with a smart key
system).
There is a possibility that the steering wheel is locked and cannot be oper-
ated.
■ 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.
Be sure to transport the vehicle with the
front wheels raised or with all four wheels
raised off the ground. If the vehicle is
towed with the front wheels contacting
the ground, the drivetrain and related
parts may be damaged or electricity gen-
erated by the operation of the motor may
cause a fire to occur depending on the
nature of the damage or malfunction.
