If your vehicle needs to be

mend having your vehicle towed by
your Lexus dealer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.

towing, and abide by all state/pro-
vincial and local laws.
If towing your vehicle with a wheel-
lift type truck, use a towing dolly.
( → P.361, 360) WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury. ■
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 vehicle may
fly off the truck, or electricity generated
by the operation of the motor may cause
a fire to occur depending on the nature
of the damage or malfunction. ■
While towing ●
When towing using a 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 dam-
aged, 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 oper-
ated. ■
Installing towing eyelets to the vehi-
cle
Make sure that towing eyelets are
installed securely.
If not securely installed, towing eyelets
may come loose during towing.
NOTICE■
To prevent damage to the vehicle
when towing using a wheel-lift type
truck ●
Do not tow the vehicle from the rear
when the power switch is off. The
steering lock mechanism is not strong
enough to hold the front wheels
straight.
●
When raising the vehicle, ensure ade-
quate ground clearance for towing at
the opposite end of the raised vehicle.
Without adequate clearance, the vehi-
cle could be damaged while being
towed.
