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.
If towing your vehicle with a
wheel-lift type truck from the front,
the vehicle’s rear wheels and axles
must be in good conditions.
(
aged, use a towing dolly or flatbed
truck.
For AWD models: If towing your
vehicle with a wheel-lift type truck,
use a towing dolly. (
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■
When towing the vehicle
2WD models
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 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.

7-2. Steps to take in an emergency
LEXUS LS500h Owner's Manual
WARNING
AWD models
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 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.
●
Make sure to disable all functions of
the vehicle height control of the elec-
tronically modulated air suspension.
Otherwise, the vehicle height may
change and part of your body may be
caught under the vehicle, possibly
causing injury. (
●
Do not perform any of the following as
doing so may cause the parking lock
mechanism to engage, locking the
rear wheels and possibly leading to an
accident resulting in death or serious
injury:
• Unfasten the driver’s seat belt and
open the driver’s door.
• Turn the power switch off.
■
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.
■
To prevent damage to the vehicle
when towing with a sling-type truck
Do not tow with a sling-type truck, either
from the front or rear.
■
To prevent damage to the vehicle
during emergency towing
Do not secure cables or chains to the
suspension components.

belts. Refer to the owner’s manual of
the flat-bed truck for the tire strapping
method.
In order to suppress vehicle movement
during transportation, set the parking
brake and turn the power switch off.
If a tow truck is not available in an
emergency, your vehicle may be tem-
porarily towed using cables or chains
secured to the emergency towing eye-
lets. This should only be attempted on
hard surfaced roads for short distances

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.
