●

Tire inflation pressure changes with tem-

perature. The displayed values may also

be different from the values measured

using a tire pressure gauge.

■

Situations in which the tire pressure

warning system may not operate prop-

erly

●

In the following cases, the tire pressure

warning system may not operate prop-

erly.

• If non-genuine Lexus wheels are used.

• A tire has been replaced with a tire that is

not an OE (Original Equipment) tire.

• A tire has been replaced with a tire that is

not of the specified size.

• Tire chains etc. are equipped.

• If a window tint that affects the radio wave

signals is installed.

• If there is a lot of snow or ice on the vehi-

cle, particularly around the wheels or

wheel housings.

• If the tire inflation pressure is extremely

higher than the specified level.

• If wheels without tire pressure warning

valves and transmitters are used.

• If the ID code on the tire pressure warn-

ing valves and transmitters is not regis-

tered in the tire pressure warning

computer.

●

Performance may be affected in the fol-

lowing situations.

• Near a TV tower, electric power plant,

gas station, radio station, large display,

airport or other facility that generates

strong radio waves or electrical noise

• When carrying a portable radio, cellular

phone, cordless phone or other wireless

communication device

If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.

●

When the vehicle is parked, the time

taken for the warning to start or go off

could be extended.

●

When tire inflation pressure declines rap-

idly for example when a tire has burst, the

warning may not function.

■

Warning performance of the tire pres-

sure warning system

The warning of the tire pressure warning

system will change in accordance with the

conditions under which it was initialized. For

this reason, the system may give a warning

even if the tire pressure does not reach a

low enough level, or if the pressure is higher

than the pressure that was adjusted to when

the system was initialized.

When replacing tires or wheels, tire
pressure warning valves and transmit-
ters must also be installed.
When new tire pressure warning
valves and transmitters are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. (

P.377)

■

When replacing the tires and wheels

If the ID code of the tire pressure warning

valve and transmitter is not registered, the

tire pressure warning system will not work

properly. After driving for about 10 minutes,

the tire pressure warning light blinks for 1

minute and stays on to indicate a system

malfunction.

A message is displayed on the multi-infor-

mation display. Also, “--” is displayed for

inflation pressure of each tire on the multi-

information display while the tire pressure

warning system determines the position.

Drive at approximately 40 km/h
(25 mph) or more for approxi-
mately 10 to 30 minutes.

When initialization is complete, the infla-

tion pressure of each tire will be displayed

on the multi-information display.
Even if the vehicle is not driven at approxi-

mately 40 km/h (25 mph) or more, initial-

ization can be completed by driving for a

long time. However, if initialization does

not complete after driving for 1 hour or

more, park the vehicle in a safe place for

approximately 20 minutes and then drive

the vehicle again.

■

When initializing

●

Initialization is performed while driving at

a vehicle speed of approximately 40

km/h (25 mph) or more.

●

Make sure to carry out initialization after

adjusting the tire inflation pressure.

Also, make sure the tires are cold before

carrying out initialization or tire inflation

pressure adjustment.

●

The tire pressure warning system can be

initialized by yourself, but depending on

the driving conditions and driving envi-

ronment, initialization may take some

time to complete.

■

The initialization operation

●

If you have accidentally turned the power

switch off during initialization, it is not

necessary to manually restart the initial-

ization again, as initialization will restart

automatically the next time the power

switch is turned to ON mode.

●

If you accidentally perform initialization

when initialization is not necessary, adjust

the tire inflation pressure to the specified

level when the tires are cold, and conduct

initialization again.

●

While the position of each tire is being

determined and the inflation pressures

are not being displayed on the multi-

information display, if the inflation pres-

sure of a tire drops, the tire pressure

warning light will come on.

■

If the tire pressure warning system is not

initialized properly

●

In the following situations, initialization

may take longer than usual to be com-

pleted or may not be possible. Normally,

initialization completes within approxi-

mately 30 minutes.

• Vehicle is not driven at approximately 40

km/h (25 mph) or more

• Vehicle is driven on unpaved roads

• Vehicle is driven near other vehicles and

system cannot recognize tire pressure

warning valve and transmitters of your

vehicle over those of other vehicles

If initialization does not complete after driv-
ing for 1 hour or more, park the vehicle in a
safe place for approximately 20 minutes
and then drive the vehicle again.

●

If the vehicle is reversed during initializa-

tion, the data up to that point is reset, so

perform the initialization procedure

again from the beginning.

●

In the following situations, initialization

will not be started or was not completed

properly and the system will not operate

properly. Perform the initialization pro-

cedure again.

• If, when attempting to start initialization,

6-3. Do-it-yourself maintenance

■

When registering ID codes

●

ID code registration is performed while

driving at a vehicle speed of approxi-

mately 40 km/h (25 mph) or more.

●

Before performing ID code registration,

make sure that no wheels with tire pres-

sure warning valve and transmitters

installed are near the vehicle.

●

Make sure to initialize the tire pressure

warning system after registering the ID

codes. If the system is initialized before

registering the ID codes, the initialized

values will be invalid.

●

but depending on the driving conditions

and driving environment, registration

may take some time to complete.

■

Canceling ID code registration

●

To cancel ID code registration after it has

been started, turn the power switch off

before driving the vehicle.

If the vehicle is driven after ID code regis-

tration is started, to cancel registration,

perform the ID code registration start

procedure again and turn the power

switch off before driving.

●

celed, the tire pressure warning light will

blink for approximately 1 minute when the

power switch is turned to ON mode and

then illuminate. The tire pressure warning

system will be operational when the tire

pressure warning light turns off.

●

If the warning light does not turn off even

after several minutes have elapsed, ID

code registration may not have been

canceled correctly. To cancel registra-

tion, perform the ID code registration

start procedure again and then turn the

power switch off before driving.

■

If ID codes are not registered properly

●

In the following situations, ID code regis-

tration may take longer than usual to be

completed or may not be possible. Nor-

mally, registration completes within

approximately 30 minutes.

• Vehicle is not parked for approximately

20 minutes or more before driving

• Vehicle is not driven at approximately 40

km/h (25 mph) or more

• Vehicle is driven on unpaved roads

• Vehicle is driven near other vehicles and

system cannot recognize tire pressure

warning valve and transmitters of your

vehicle over those of other vehicles

Effects of incorrect tire inflation pres-

sure

Driving with incorrect tire inflation pressure

may result in the following:

●

Reduced fuel economy

●

Reduced driving comfort and poor han-

dling

●

Reduced tire life due to wear

●

Reduced safety

●

Damage to the drivetrain

If a tire needs frequent inflating, have it

checked by any authorized Lexus retailer

or Lexus authorized repairer, or any reli-

able repairer.

■

Instructions for checking tire inflation

pressure

When checking tire inflation pressure,

observe the following:

●

Check only when the tires are cold.

If your vehicle has been parked for at

least 3 hours or has not been driven for

more than 1.5 km or 1 mile, you will get an

accurate cold tire inflation pressure read-

ing.

●

Always use a tire pressure gauge.

It is difficult to judge if a tire is properly

inflated based only on its appearance.

●

It is normal for the tire inflation pressure

to be higher after driving as heat is gener-

ated in the tire. Do not reduce tire infla-

tion pressure after driving.

●

Passengers and luggage weight should

be placed so that the vehicle is balanced.

Tire inflation pressure

Make sure to maintain proper tire
inflation pressure. Tire inflation
pressure should be checked at
least once per month. However,
Lexus recommends that tire infla-
tion pressure be checked once
every two weeks.

WARNING

■

Proper inflation is critical to save tire

performance

Keep your tires properly inflated.

If the tires are not properly inflated, the

following conditions may occur which

could lead to an accident resulting in

death or serious injury:

●

Excessive wear

●

Uneven wear

●

Poor handling

●

Possibility of blowouts resulting from

overheated tires

●

Air leaking from between tire and

wheel

●

Wheel deformation and/or tire dam-

age

●

Greater possibility of tire damage

while driving (due to road hazards,

expansion joints, sharp edges in the

road, etc.)

NOTICE

■

When inspecting and adjusting tire

inflation pressure

Be sure to put the tire valve caps back

on.

If a valve cap is not installed, dirt or mois-

ture may get into the valve and cause an

air leak, resulting in decreased tire infla-

tion pressure.
