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 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 engine switch <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.

■

To prevent damage to the vehicle

when towing using a wheel-lift type

truck

When raising the vehicle, ensure ade-

quate ground clearance for towing at the

opposite end of the raised vehicle. With-

out adequate clearance, the vehicle

could be damaged while being towed.

■

To prevent damage to the vehicle



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 tow-
ing eyelet. (



P.357)

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.

WARNING

■

Maintenance of the tires

Each tire, including the spare (if provided), should be checked monthly when cold and

inflated to the inflation pressure recommended by the vehicle manufacturer on the vehi-

cle placard or tire inflation pressure label (tire and load information label). (If your vehicle

has tires of a different size than the size indicated on the vehicle placard or tire inflation

pressure label [tire and load information label], you should determine the proper tire

inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitor-

ing system (TPMS-tire pressure warning system) that illuminates a low tire pressure tell-

tale (tire pressure warning light) when one or more of your tires is significantly under-

inflated. Accordingly, when the low tire pressure telltale (tire pressure warning light) illu-

minates, you should stop and check your tires as soon as possible, and inflate them to the

proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat

and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life,

and may affect the vehicle’s handling and stopping ability.

Please note that the TPMS (tire pressure warning system) is not a substitute for proper

tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure,

even if under-inflation has not reached the level to trigger illumination of the TPMS low

tire pressure telltale (tire pressure warning light).

Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-

function indicator to indicate when the system is not operating properly. The TPMS (tire

pressure warning system) malfunction indicator is combined with the low tire pressure

telltale (tire pressure warning light). When the system detects a malfunction, the telltale

will flash for approximately one minute and then remain continuously illuminated. This

sequence will continue upon subsequent vehicle start-ups as long as the malfunction

exists. When the malfunction indicator is illuminated, the system may not be able to

detect or signal low tire pressure as intended.

TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,

including the installation of replacement or alternate tires or wheels on the vehicle that

prevent the TPMS (tire pressure warning system) from functioning properly. Always

check the TPMS (tire pressure warning system) malfunction telltale after replacing one

or more tires or wheels on your vehicle to ensure that the replacement or alternate tires

and wheels allow the TPMS (tire pressure warning system) to continue to function prop-

erly.

To ensure the tire pressure warning system operates properly

Do not install tires with different specifications or makers, as the tire pressure warning

system may not operate properly.

A tire should only be repaired with the
emergency tire puncture repair kit if the
damage is caused by a nail or screw pass-
ing through the tire tread.
• Do not remove the nail or screw from

the tire. Removing the object may widen
the opening and make emergency
repair with the repair kit impossible.

• To avoid sealant leakage, move the vehi-

cle until the area of the puncture, if
known, is positioned at the top of the tire.

If you have a flat tire

Your vehicle is not equipped with a
spare tire, but instead is equipped
with an emergency tire puncture
repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired temporarily
with the emergency tire puncture
repair kit. (The emergency tire
puncture repair kit contains a bot-
tle of sealant. The sealant can be
used only once to temporarily
repair one tire without removing
the nail or screw from the tire.)
Depending on the damage condi-
tion of the flat tire, it may not be
able to repaired with the emer-
gency tire puncture repair kit.
(

WARNING

■

When fixing the flat tire

●

Stop your vehicle in a safe and flat

area.

●

Do not touch the wheels or the area

around the brakes immediately after

the vehicle has been driven.

After the vehicle has been driven, the

wheels and the area around the brakes

may be extremely hot. Touching these

areas with hands, feet or other body

parts may result in burns.

●

Connect the valve and hose securely

with the tire installed on the vehicle.

If the hose is not properly connected to
the valve, air leakage may occur or seal-
ant may be sprayed out.

●

If the hose comes off the valve while

inflating the tire, there is a risk that the

hose will move abruptly due to air

pressure.

●

After inflation of the tire has com-

pleted, the sealant may splatter when

the hose is disconnected or some air is

let out of the tire.

●

Follow the operation procedure to

repair the tire. If the procedure is not

followed, the sealant may spray out.

●

Keep back from the tire while it is

being repaired, as there is a chance of

it bursting while the repair operation is

being performed. If you notice any

cracks or deformation of the tire, turn

off the compressor switch and stop the

repair operation immediately.

●

The repair kit may overheat if oper-

ated for a long period of time. Do not

operate the compressor continuously

for more than 40 minutes.

●

Parts of the repair kit become hot

during operation. Be careful handling

the repair kit during and after opera-

tion. Do not touch the metal part con-

necting the bottle and the compressor.

It will be extremely hot.

Driving to spread the liquid sealant

evenly

Observe the following precautions to

reduce the risk of accidents.
Failing to do so may result in a loss of

vehicle control and cause death or seri-

ous injury.

●

Drive the vehicle carefully at a low

speed. Be especially careful when

turning and cornering.

●

If the vehicle does not drive straight or

you feel a pull through the steering

wheel, stop the vehicle and check the

following:

• Tire condition. The tire may have sepa-

rated from the wheel.

• Tire inflation pressure. If the tire infla-

tion pressure is 19 psi (130 kPa, 1.3
kgf/cm

or bar) or less, the tire may be

severely damaged.

NOTICE

■

When performing an emergency

repair

●

Perform the emergency repair without

removing the nail or screw that has

punctured the tread of the tire. If the

object that has punctured the tire is

removed, repair by the emergency tire

puncture repair kit may not be possi-

ble.

●

The repair kit is not waterproof. Make

sure that the repair kit is not exposed

to water, such as when it is being used

in the rain.

●

Do not put the repair kit directly onto

dusty ground such as sand at the side

of the road. If the repair kit vacuums up

dust etc., a malfunction may occur.

●

Make sure the sealant bottle of the

repair kit is in a vertical position. The

repair kit does not operate properly

when it is laid.

■

Precautions for the emergency tire

puncture repair kit

●

The repair kit power source should be

12 V DC suitable for vehicle use. Do

not connect the repair kit to any other

source.

●

If gasoline splatters on the kit, the kit

may deteriorate. Take care not to

allow gasoline to contact it.

●

When the emergency tire puncture

repair kit is not being used, be sure to

leave it in the plastic bag and keep it in

its proper storage position to prevent it

from being exposed to dirt or water.

●

Store the repair kit in its assigned

place out of reach of children.

●

Do not disassemble or modify the

repair kit. Do not subject parts such as

the air pressure indicator to impacts.

This may cause a malfunction.

■

To avoid damage to the tire pressure

warning valves and transmitters

When a tire is repaired with liquid seal-

ants, the tire pressure warning valve and

transmitter may not operate properly. If a

liquid sealant is used, contact your Lexus

dealer or other qualified service shop as

soon as possible. After use of liquid seal-

ant, make sure to replace the tire pres-

sure warning valve and transmitter when

repairing or replacing the tire.
