GX 460 _O M_ OM6 0L 72U _( U)
If your Lexus is transported by a flatbed
truck, it should be tied down at the
locations shown in the illustration.
If you use cables or chains 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 temporarily
towed using cables or chains secured to the emergency towing hooks. This
should only be attempted on hard surfaced roads for 50 miles (80 km) at low
speeds.
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.
