flatbed truck, it should be tied
down at the locations shown in the
illustration.
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45°.
Do not overly tighten the tie
downs or the vehicle may be dam-
aged.
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 distances at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes. The

■While towing
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
■ Wheel nut wrench
Wheel nut wrench is installed in luggage compartment. ( →P. 610)
■ Towing eyelet installation hole on the rear of the vehicle
The hole is equipped for fastening the
vehicle while shipping. Your vehicle can-
not tow another vehicle.
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 power switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
■ Installing towing eyelets to the vehicle
● The towing eyelets are only for the vehicle equipped with them. Do not use
the towing eyelets for another vehicle, and do not use the towing eyelets
for this vehicle on another 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.
