the vehicle, and possibly a fire or injury.

●

Never use a fuse of a higher amperage

rating than that indicated, or use any

other object in place of a fuse.

●

Always use a genuine Lexus fuse or

equivalent.

Never replace a fuse with a wire, even

as a temporary fix.

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.
(



P.459, 457) If they are dam-

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. (



P.459, 457)

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.

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. (



P.335)

●

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.

When using a flat-bed truck to trans-
port the vehicle, use tire strapping
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
at under 18 mph (30 km/h).
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.

To have your vehicle towed by another

vehicle, the towing eyelet must be
installed to your vehicle. Install the tow-
ing eyelet using the following proce-
dure.

Take out the phillips-head screw-
driver and towing eyelet.
