When trouble arises
7-2.Steps to take in an emergency
If your vehicle needs to be
towed
If towing is necessary, we recom-
mend having your vehicle towed by
your Lexus dealer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.
Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■When towing the vehicle
LC500: Be sure to transport the vehicle
with all four wheels raised off the ground.
If the vehicle is towed with the tires con-
tacting the ground, the drivetrain and
related parts may be damaged or an
accident may occur due to a change in
direction of the vehicle.
LC500h: Be sure to transport the vehi-
cle with all four wheels raised off the
ground. If the vehicle is towed with the
tires contacting the ground, the drive-
train and related parts may be damaged,
an accident may occur due to a change
in direction of the vehicle 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 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 engine switch
switch> off.
This may lead to an accident as the
rear wheels will be locked by the park-
ing lock.
Also, there is a possibility that the
steering wheel is locked and cannot be
operated.
