GS450h_OM_OM30F70U_(U)If your vehicle is transported by a
flatbed truck, it should be tied down
at the locations shown in the illustra-
tion.
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 damaged.
If a tow truck is not available in an emergency, your vehicle may be tempo-
rarily towed using cables or chains secured to the emergency towing eye-
lets. This should only be attempted on hard surfaced roads for short
distances at under 3 mph (5 km/h).

cle’s wheels, drive train, axles, steering and brakes must be in good condi-
tion.

tion, making steering and braking more difficult.
■Wheel nut wrench

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 exces-
sive 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.
●Do not turn the power 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.
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 and related parts may be dam-
aged, an accident may occur due to a
change in direction of the vehicle or electric-
ity generated by the operation of the motor
may cause a fire to occur depending on the
nature of the damage or malfunction.
