7-2.Steps to take in an emergency

The following may indicate a problem
with your transmission. Contact your
Lexus dealer or commercial towing
service before towing.

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

Be sure to transport the vehicle with the

front wheels raised or with all four wheels

raised off the ground. If the vehicle is

towed with the front wheels contacting

the ground, the drivetrain and related

parts may be damaged.

■

While towing (vehicles with a towing

eyelet)

●

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 off.

There is a possibility that the steering

wheel is locked and cannot be oper-

ated.

■

Installing towing eyelets to the vehi-

cle (vehicles with a towing eyelet)

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 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 (vehicles

with a towing eyelet)

Do not secure cables or chains to the

suspension components.

Situations when it is necessary to
contact dealers before towing

7-2. Steps to take in an emergency

 The engine is running but the vehi-

cle does not move.

 The vehicle makes an abnormal

sound.

Do not tow with a sling-type truck to
prevent body damage.



From the front

Release the parking brake.



From the rear

Use a towing dolly under the front
wheels.

If your vehicle is transported by a flat-
bed truck, it should be tied down at the
locations shown in the illustration.

If you use chains or cables to tie down
your vehicle, the angles shaded in
black must be 45°.
Do not overly tighten the tie downs or
the vehicle may be damaged.

hen tro

ises

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 at most 50
miles (80 km) 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 towing eyelet.
(

P.363)

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.

Insert the towing eyelet into the
hole and tighten partially by hand.

Tighten down the towing eyelet
securely using a wheel nut wrench
or hard metal bar.

Securely attach cables or chains to
the towing eyelet.

Take care not to damage the vehicle body.

Enter the vehicle being towed and
start the engine.

If the engine does not start, turn the engine

switch to IGNITION ON mode.



If the tire pressure warning light blinks for

approximately 1 minute then stays on

There may be a malfunction in the tire pres-

sure warning system. Have the vehicle

inspected by your Lexus dealer immedi-

ately.



If the tire pressure warning light comes

After the temperature of the tires has

lowered sufficiently, check the inflation

pressure of each tire and adjust them to

the specified level.

If the warning light does not turn off

even after several minutes have

elapsed, check that the inflation pres-

sure of each tire is at the specified level

and perform initialization. (

P.321)

■

The tire pressure warning light may

come on due to natural causes

The tire pressure warning light may come

on due to natural causes such as natural air

leaks and tire inflation pressure changes

caused by temperature. In this case, adjust-

ing the tire inflation pressure will turn off the

warning light (after a few minutes).

■

When a tire is replaced with a spare tire

The compact spare tire is not equipped with

a tire pressure warning valve and transmit-

ter. If a tire goes flat, the tire pressure warn-

ing light will not turn off even though the flat

tire has been replaced with the spare tire.

Replace the spare tire with the repaired tire

and adjust the tire inflation pressure. The

tire pressure warning light will go off after a

few minutes.

ing system may not function properly

P.319

WARNING

■

If both the ABS and the brake system

warning lights remain on

Stop your vehicle in a safe place immedi-

ately 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 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 precau-

tions.

Failure to do so could cause a loss of

vehicle control and result in death or

serious injury.

●

Stop your vehicle in a safe place as

soon as possible. 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. Check the tires. If a tire is flat,

change it with the spare tire and have

the flat tire repaired by the nearest

Lexus dealer.

●

Avoid abrupt maneuvering and brak-

ing.

If the vehicle tires deteriorate, you

could lose control of the steering

wheel or the brakes.

WARNING

■

If a blowout or sudden air leakage

should occur

The tire pressure warning system may

not activate immediately.

■

Maintenance of the tires

Each tire, including the spare (if pro-

vided), should be checked monthly when

cold and inflated to the inflation pressure

recommended by the vehicle manufac-

turer on the vehicle placard or tire infla-

tion pressure label (tire and load

information label). (If your vehicle has

tires of a different size than the size indi-

cated on the vehicle placard or tire infla-

tion 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

monitoring system (TPMS-tire pressure

warning system) that illuminates a low

tire pressure telltale (tire pressure warn-

ing light) when one or more of your tires

is significantly under-inflated. Accord-

ingly, when the low tire pressure telltale

(tire pressure warning light) illuminates,

you should stop and check your tires as

soon as possible, and inflate them to the

proper pressure. Driving on a signifi-

cantly under-inflated tire causes the tire

to overheat and can lead to tire failure.

Under-inflation also reduces fuel effi-

ciency and tire tread life, and may affect

the vehicle’s handling and stopping abil-

ity.

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 illumina-

tion of the TPMS low tire pressure telltale

(tire pressure warning light).

Your vehicle has also been equipped with

a TPMS (tire pressure warning system)

malfunction 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 pres-

sure 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 subse-

quent 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 func-

tioning 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 properly.

NOTICE

■

To ensure the tire pressure warning

system operates properly

Do not install tires with different specifi-

cations or makers, as the tire pressure

warning system may not operate prop-

erly.
