4527-2. Steps to take in an emergency
When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the
owner’s manual of the flat-bed
truck for the tire strapping
method.
In order to suppress vehicle
movement during transporta-
tion, set the parking brake and
turn the power 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 eyelets. This
should only be attempted on
hard surfaced roads for short
WARNING
■When towing the vehicle
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 vehi-
cle may fly off the truck, or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending on the nature of
the damage or malfunction.
NOTICE
■To prevent damage to the
vehicle when towing using a
wheel-lift type truck
●Vehicles without smart key sys-
tem: Do not tow the vehicle from
the rear when th e power switch
is in the “LOCK” position or the
key is removed. The steering
lock mechanism is not strong
enough to hold the front wheels
straight.
●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.
■Towing with a sling-type
truck
Do not tow with a sling-type truck
to prevent body damage.

■While towing
If the hybrid system is off, the power
assist for the brakes and steering
will not function, making steering

WARNING
Observe the following precau-
tions. Failure to do so may result
in death or serious injury.
■While towing (vehicles with
towing eyelet)
●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.
●Vehicles without smart key sys-
tem: Do not turn the power
switch to the “LOCK” position.
There is a possibility that the
steering wheel is locked and
cannot be operated.
■Installing towi ng eyelets to
the vehicle (vehicles with
towing eyelets)
Make sure that towing eyelets are
installed securely. If not securely
installed, towing eyelets may
come loose during towing.

vehicle during emergency
towing (vehicles with towing
eyelet)
Do not secure cables or chains to
the suspension components.
