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 <power

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.

342

7-2. Steps to take in an emergency

In the following situations, it is not pos-
sible to be towed by another vehicle
using cables or chains, as the rear
wheels may be locked due to the park-
ing lock. Contact your Lexus dealer or
commercial towing service.



There is a malfunction in the shift

control system. (

WARNING

■

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 engine switch <power

switch> is off. The steering lock mecha-

nism 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.



From the rear

Use a towing dolly under the front
wheels.

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 engine
switch <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 screwdriver and the
towing eyelet. (

P.322)

Remove the eyelet cover using a
flathead screwdriver.

To protect the bodywork, place a rag

between the screwdriver and the vehicle

body as shown in the illustration.

WARNING

■

If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehicle

will become extremely unstable during braking, and the ABS system may fail, which could

cause an accident resulting in death or serious injury.

■

When the electric power steering system warning light comes on

When the light comes on in yellow, the assist to the power steering is restricted. When the

light comes on red, the assist to the power steering is lost and handling operations of the

steering wheel become extremely heavy. When steering wheel operations are heavier

than usual, grip the steering wheel firmly and operate it using more force than usual.

■

If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-

cle control and result in death or serious injury.

●

Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 50

mph (80 km/h).

●

Check and adjust the tire inflation pressure immediately.

●

If the tire pressure warning light comes on even after tire inflation pressure adjustment,

it is probable that you have a flat tire. Have the flat tire replaced by the nearest Lexus

dealer.

●

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose

control of the steering wheel or the brakes.

■

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.
